Many of us (I would think) are looking for notebooks that can be cooled passively for light tasks, and quietly under load. Usually this is only achievable with software controllable fan speeds. (speedfan, i8kfangui etc).

The following easy-to-acquire info can really help to evaluate the quietness of a laptop IMHO. Contribute! See examples below.

1) Laptop mnfr & model number
2) Fan behavior (default start/stop temperature)
3) Support for speedfan, or other fan control software, and how it can improve the noise level.
4) Does the mnfr power management utility or bios help?
5) Subjective (or measured!) fan & harddrive noise levels & character
6) Can it run passive at low loads?

The holy grail would be a laptop that can stay below 60 degrees without help from the fan for light loads, yet still sport a powerful video card. I have yet to see the mobile GPU market really kick down the temps when their cards aren't doing 3D. They are seemingly a big liability still in laptops.

Also good would be a laptop that can idle at 50 degrees or less without active cooling. As long as it can stay under 60 though, it's a sensible choice for a low-noise laptop (all other things being equal).

The list! (i'll just keep editing this post as you guys post info)

NOTE: This is not a "recommended laptops" list. Everything goes here, the good, the bad, and hideously loud.

**********************************************************
**********************************************************


Thin & Light


IBM X40 (12.1", Low-Voltage 1.4Ghz P-M, Intel Extreme graphics 2)
Seemingly quiet laptop. Fan spins up seldomly and is reasonably quiet. 1.8" Hard drive looks stellar noisewise. Speenfan doesn't seem to work. A+ battery life Gross overview only. Not yet tested in ideal quiet conditions. - cloneman

Dell Inspiron 2200 (1.3ghz CelM, Intel GMA900 768ram, 40gb)
Absolutely silent. Top of the laptop and palmrest never gets even warm, though the underside of the laptop does. Using I8kfangui, I've set it to switch the fan on low only when temps hit 60C. When placed on a desktop, temps never exceed 55C and usually hover around 50C. - davidstone28

Acer Travelmate 290e
Uses a Celeron-M 1.3GHz, and fan doesn't run until I do some intense computing. Hard drive is also very very quiet. No mods, no fanGUI,...
Palm rests stay cool. Bottom gets warm, and rear of keyboard, next to display. steve8pi

Mainstream

Dell Inspiron 6400 (15.4" Wide, Core 2 Duo 2.16Ghz 667FSB, Mobility Radeon X1400)
Fan control is supported by i8kfangui. With the fan off, temps will rise, even undervolted & idle. Cannot be comfortably cooled passively. Fan does not need to go higher than its first stepping under most use, (2400rpm), and its fairly quiet. The hard drive (120GB WD, reviewed on this site) is definitely audible, but not intrusive. A coil whine howeever seems to be present, and is piped through the sound card as well. It's dependant on load and speed/voltage control. This is my 3rd sample. A decent choice if yours doesn't whine. If the fan control would allow lower rpm it would be much better. 7/10- cloneman

Dell Inspiron 6400 (15.4" WS) Core 2 Duo, T5600 (1.83 GHz) with ATI Mobility Radeon X1400
@IDLE:
fan on/off at 48/38
With FanGUI set for 55/47, still cycles, but less often.
Passive: 63? degrees in cool room
Hard Drive I consider somewhat loud for home use, but not noticable in an office environment - steve8pi
Note by cloneman: My thoughts exactly. Not safe for passive cooling, but reasonable overall, though not close to SPCR standards.


Notebooks with Powerful Graphics


Toshiba a100-sk9 (15.4" wide, Core Duo 2Ghz, Geforce Go 7600)
No fan control support as of now. Fan is noisy, easily audible at 4-5m away. Fan turns on after a few minutes of use, and will never turn off after that. Laptop base feels cool on your lap, could definitely survive much higher temps. With better fan control this would be excellent. 6.5/10 - cloneman

Dell Inspiron 9400 (E1705) , T7400 CPU with Nvidia 7900GS Video
Uses 2 heatsinks and 2 fans to cool the CPU & GPU seperately. This results in a more efficient operation and the possiblity to cool almost completely passively on idle. Coil whine can be controlled & minimized, but is present. Impressive acoustics for a desktop replacement. Both fans are quieter than the 6400 model's fan, & the GPU fan is barely audible over the HD. This laptop overclocks very well (without affecting it's clocks in powersaving mode). Would have even better passive & oc capabilities if it has the dual heatpipe cooler for the VGA card (found in the xps version)8.7 /10 - cloneman

I've been pleasantly surprised by the tweaking capabilities of my Dell laptop using I8kfanGUI - http://www.diefer.de/i8kfan/index.html

Fan control via I8kfangui and undervolting via RMClock has yielded a much cooler laptop with longer battery life.

please post info like default start and stop temperatures, bios options of interest, and the model number you got. Also feel free to give subjective noise impressions, e.g. the hard drive. Then I'll add it to the list!

Here's my (slightly extended) review of mine (now returned).

Well here's my contribution to start the list!

---------------------------------------------------------------------------------
TOSHIBA a100-sk9
Centrino Duo T2500 (2Ghz), Geforce 7600 GO 256MB

- Speedfan and other utilites not supported. Haven't tested under linux.
NHC (notebook hardware control) seems like might work if you know C#. (supposedly could set fan start and stop temps)

- Fan starts a few minutes after system bootup (35 degree startup temp?)
It never turns off after that. Does not ramp up to max rpm either. Noisy, audible from 5m away.

- Toshiba's power settings (cooling mode -> battery optimized) seems to have no effect on fan behaviour

- Bios has nothing of interest

- The base of the laptop feels very cool. This one could definitely take more thermal punishment, perhaps toshiba shivers at the thought off non-paranoid PWM on its machines with powerful graphics cards?

Dell Inspiron 1200, 1.4GHz Banias (originally 1.3GHz Celeron M) 256MB ram, 30GB hdd, GMA 900.

Same design as Dell Inspiron 2200 above. Upgraded to 1.4GHz Banias Pentium M for $11 off E-bay. Now that I can adjust multipliers and voltages, I have permanently set the CPU at 600MHz at 0.700 vcore using RMclock. I previously had fan set to turn on low speed at 60 C via i8kfangui, but have now set it to turn on at 35C, and off again at 30C (at 60C, the fan would never turn on, the Pentium M never got hotter than 45 C under continuous 100% cpu load). Doing this occasionally moves air through the laptop, keeping the GPU, hdd, and memory a lot cooler. If my apartment is less than 70 deg F, I can surf the internet for hours and never have the fan turn on (cpu temp will hover around 28-33C). The underside of the laptop just barely gets warm now. The underclocked/undervolted Pentium M has increased my battery runtime by a full hour, giving me a total of 3.5 hours runtime on a 43 watt/hr NiMH.

Dell Inspiron 6400 Core 2 Duo, T5600 (1.83 GHz) with ATI Mobility Radeon X1400.

From Dell fan cuts on/off at 48/38, cycling even when idle.
With FanGUI set for 55/47, still cycles, but less often.

As an experiment, I tried to see where passive cooling would stabilize. When idle, and with notebook at slight angle (rear propped up about 4cm), it looked like it was maybe settling around 63C (cool room temp). I wouldn't run it this way for long.

There is a mode that's kind of interesting. In FanGUI, go to Options/DisplayOptions/SensorUpdates/FanSettingEnforcement and set it to 1 second. In this mode, it seems the original Dell control starts the fan, and then fanGUI stops it before it gets up to speed, resulting in little bursts of air. The noise level is very low, and the temp stays around 50C. It sounds kindof like the computer is breathing softly. (gasping?)
But this may be a little stressful on the fan, possibly shortening it's life.

Hard Drive I consider somewhat loud for home use, but not noticable in an office environment.

Acer Travelmate 290e

It's not a current notebook, and it's not a high-performance one, but it's the one I use at home, and it's silent. Uses a Celeron-M 1.3GHz, and fan doesn't run until do some intense computing. Hard drive is also very very quiet. No mods, no fanGUI,...

Palm rests stay cool. Bottom gets warm, and rear of keyboard, next to display.

I really like the Celeron-M. I think it's a very efficient processor, and still powerful enough for most tasks.

Despite what Intel tries to claim, the Core Duo and Core 2 Duo run quite a bit hotter than the -M series. (and need more cooling)

My Inspiron 1200 isn't listed at the top of the page. I guess the only truely silent, passively cooled, lowest power consuming, cheapest to buy laptop here isn't worthy of being listed. :?

It most certainly is! This list is a work in progress (and even barely at that!)

I for one am very interigued. Does dell still sell those?

Please give the specs & other info as indicated in the original post and ideally the hard drive model#/ impressions if its a silent champ.

I am currently studying an inspiron 9400/e1705 (T7400, 7900GS). Looking decent so far!

If I I force settings down, the CPU "struggles" to reach 60 degrees on idle.

The GPU fan on the Nvidia 7900GS seems to be dead quiet on low (noticeableably quieter than the cpu fan).

It looks like we have a winner, at least with my preliminary tests, for a high performance laptop that can run passive on idle. It looks better than the 6400, which relies on a single fan and heatpipe arrangement to cool the CPU & GPU. That system quickly climbed above 65 degrees celcius if the fan was forced off.

Of course, i8kfangui is crucial.

I'll be posting my final thoughts within a week or so.

Also good news: the infamous whining noise that I had in my 6400 (that seems to plague macbook pro users as well) seems to be missing from this laptop. Well, I do occasionally hear _some_ electrical noise, but thus far it hasn't bothered me.

I'm impressed so far.

Here's an update

I've had the laptop for a few days now. The famous coil whine noise (described in the post "Forever whining CPUs") IS indeed present, however, it can be suppressed by using RMclock (see instructions in the other thread), or preferrably, plugging in a USB Drive.

This supresses the noise _almost_ entirely. My extra sensitive ears do percieve that there is still some electronic noise present - but it hasn't bothered me yet - much anyway. I can confirm that it's better than the two inspiron 6400s I was looking at - two samples which both whined terribly and uncontrolably. Who knows how they would be have with ordinary Core Duos?

Anyway, on the more interesting aspects. The hard drive is definitely audible, but, it doesn't bug me, the character is smooth. AAM is apparently supported, I haven't toyed with it as I feel no need to.

The most important part of this mini-review is the fan behavior.
By default, it appears that the system turns both fans to low (2400rpm CPU, 2700rpm VGA) as soon as either one of them reaches 70 degrees-ish. If you run the CPU at SpeedStep's minimum state, it will sit around 53 degrees (idle & fan forced off). As for the GPU, if you use Nvidia Powermizer and set it to minimum, it takes a long time to reach 70 degrees (passive - fan forced off). However, the GPU's fan is smaller, and even at 2,700rpm it's quieter than the cpu fan at 2,400rpm.

So what does this mean? Well for starters, it means this laptop can be quiet. I think it's a little hard to cool the GPU completely passively, but the GPU fan is so quiet at low that it is barely more disturbing than the hard drive - I would have no trouble having it on all time.

As for the CPU, if you force speedstep to low (or play with undervolting), active fan cooling should be unnecessary for light tasks.

Keeping both fans on slow all time time is also an option (i8kfangui comes into play). I personally find them quite smooth and unobtrusive. The CPU fan is a little louder than the GPU (even though it spins slower), but as a whole I would say it's fairly quiet, maybe even silent for non-spcr people.

In the end the genius is behind the use of two separate cooling systems for the GPU & CPU. The inspiron 6400 has a single heatsink&fan to handle the output from the CPU + GPU (albeit an easier-to-cool GPU) which results in basically impossible near-passive operation. It'd be be interesting to see how the 6400 would perform with an intel GMA 950 vs the ATI X1400 (I had the ATI in that system).

The 9400, on the other hand, uses 2 fans and 2 heatsinks to shuttle heat out. En plus, it's got a Montrous 7900GS, a very efficient & powerful, allegedly 20W Moblile GPU. You end up with a system that supports fan control through i8kfangui, is a great performer, can run near-passive. To top it all off, the stock fan settings are reasonble for the noise-minded people.

It would be interesting to see what a difference it would make if the stock thermal good was replaced by Arctic Silver 5. We've all seen the big mess apple makes with the TIM, would be interesting to see what kind of job Dell does. I personally don't have the guts to open a laptop still under warranty - but I think it adds a plus to this laptop that these very nice characteristics are all with a stock setup.

My biggest worry right now is that the infamous coil whine will eventually start to bother me, or become louder under certain conditions. It's important to note that I haven't used this system on battery much, (it's a desktop replacement after all) situations in which whine is commonly known to be worse.

Ah well. Enough ranting for today.

P.S. By the way, Inspiron 6400 = E1505
and Inspiron 9400 = E1705

Dell uses different naming for marketing reasons. Both models are the same.

Relevant specs for machine:

T7400 CPU, Nvidia 7900GS 256MB, 2GB 533Mhz RAM, ST9160821AS Seagate Momentus 5400.3 160GB Sata HD

P-M 1.6GHz Banias, ATI Mobility Radeon, 1GB Ram, 40GB Fujitzu 4200rpm HDD

- The air intake is below the laptop on its base. Allowing this area to be open to the air allows it to run without the fan coming on. CPU is undervolted by 0.2v per step. Temps for fan to kick in TBA

- 'Thinkpad Fan Control' works great with fully configurable fan speeds allowing you to choose at what temp you want certain fan levels to kick in.

- 'Notebook Hardware Control v2.0' allows undervolting to lower heat signature. e.g. at 600mhz 0.780V is required.

- Bios not entered yet.

- Fan noise character needs identifing.

(cross posted from the "whining laptops" thread + info on video card. I haven't run speedfan or anything. Didn't occur to me :? )

The laptop I'm using right now is a Dell Latitude D520, T2300 at 1.66GHz. Video card is inbuilt Intel 945GM Express on a 14.1" 5x4 display (I don't really dig widescreens. Besides this was a cheap used machine). The coil whine was the first thing I noticed and primarily on sites with Flash media. Like silentpcreview.com actually which is the site I used for testing fixes.

The USB fix works for me (note I have to disable power management on all root hubs, not just one) and makes all the difference. The battery life is indeed adversely affected but I still get over 3 hours. I say the USB fix works primarily as a bug in Windows XP rather than as a predictable side effect. I wouldn't otherwise see why the processor would be prevented from entering C3.

As an aside for those interested in a Latitude, the fan never goes on making it a quiet machine, processor wise at least. I can run Prime 95 and make it spin (I've had to now cause I've forgotten what the fan sounds like) and the fan isn't noisy but does have high pitch to it which isn't great.

Negatives are the annoying tweet (exactly like a cricket inside the machine) when charging above 75% that is really really annoying - what exactly is going on with power circuitry these days!?? Lucky you can avoid the issue most of the time.

And the hard disk in this machine is a SATA 40GB drive - a Fujitsu MHV2040BH. The idle noise isn't bad but the seek is quite loud. Probably the way XP does its filesystem flushes make it worse - "Chik chik" pause "chik chik" pause "shhhhhhhhhhhhhhh" and then "clack!" as it parks. Urgh. I guess I've never noticed hard disks before over the howl of fans :wink: but this is quite annoying and Dell don't make any effort to soft mount it (par for the course I'd say). Maybe I'll go check out some silentpcreview reviews on hard drives then!

Conor.

PS: My brothers old Latitude C640 (P4m) makes the same coil whine on flash media based sites. This has been around for a while. Of course he doesn't notice and thinks I'm just nuts :roll:

1. HP Compaq NC6400 (core duo t2400)
2. Starts at 50C, then stops at 43C
3. Does not support speedfan. Notebook hardware control can control the fan speeds and the temperature thresholds. Just need to download the ACPI modules for the model.
4. there is no manufacturer power management utility nor does the bios have any power management configurability.
5 & 6. The notebook can be passively cooled on battery power. On battery, the processor can go into lower sleep states (c3 and lower), while on ac power, it does not. I'm not sure why it does this, but according to the HP support forums, it seems that HP designed the notebook this way.

When it's running on battery power (ambient temp is around 28C right now), then the cpu idles between 45-46 C. During this usage, the fan does not run at all, as the fan only turns on when it hits 50C.

One piece of info, though. I am running the F.06 bios. Running the latest F.0A bios heats up the notebook more quickly (the release notes state that nothing was changed in the thermal management, but i beg to differ). Because of this, running the F.0A bios prevents the notebook from running passively cooled on battery power.

Currently running vista 32 business (superfetch and aero theme off)

I know HP messed with the C4 power state in the latest revision of some bioses, in order to deal with coil whine. I posted the link in the "Widespread notebook whine" thread

Thanks for the review and contributing to this ever growing list.

Welcome to SPCR! ;^P

I've got 2 mini reviews (of somewhat older models but still...):

Dell Latitude D610 (My current comp)
---------------------
1.86 Pentium-M running at 1.148volts, X300 Mobile
Has a single fan, both CPU and GPU are cooled by it. Fan is very well behaved, comes on at low speed, only audible in a quiet room, smooth airflow noise only. Hard to say for sure but kicks into high at about 55 degrees (rarely happens when not gaming), even at high, the noise signutare is not disturbing. Power draw is about 12 watts at idle at min display brightness with all power saving features on, more like 17 watts if you wanna see the screen. Only black mark on this machine is the 60gb toshiba harddisk that clicks every 3 seconds or so. (oh, and the fact that it tries to melt if I run Civ4...)

Dell Latitude D505 (of a friend)
---------------------
1.4 Banias Pentium-M, with older chipset that uses DDR, integrated graphics
This has pretty much the same cooling system and the noise signutare is pretty much the same, that is very very quiet. Because of the lack of graphics, I cannot recall ever hearing its fan on high. It is much cooler running than the 610, idle power is 9watts at min screen brigthness. It actually runs 4 hours 50 mins on the standard battery, amazing.


On a side note: The harddisk in my D610 has a tendency to heat up too much, up to 50-52 degrees. It is located on the bottom of the left front side. If i do anything like defrag it shoots up to the 50s and will not drop for hours and hours. Anyone know how I can reduce its temp? I am pretty sure it is not cooking because of cpu or system temps, it seems to cook itself. For example, right now, CPU is at 38, hdd at 45.....

Thanks for the reviews!

On my dell 6400 the HD temps would sit at around 53 degrees if power management was disabled. During intensive activity, it could hit 57 degrees. I don't know if it was defective... my 9400 runs much cooler. There's not much for the cooling to escape, as the drive is surrounded in plastic, so the main factor I guess would be the heat dissipated by the drive.

- The air intake is below the laptop on its base. Allowing this area to be open to the air allows it to run without the fan coming on. CPU is undervolted by 0.2v per step. Temps for fan to kick in TBA

- 'Thinkpad Fan Control' works great with fully configurable fan speeds allowing you to choose at what temp you want certain fan levels to kick in.

- 'Notebook Hardware Control v2.0' allows undervolting to lower heat signature. e.g. at 600mhz 0.780V is required.

- Bios not entered yet.

- Fan noise character needs identifing.


After some proper use in dynamic mhz undervoltaged.

Single fan, both CPU and GPU are cooled by it but it off 99% of the time, it rarely starts as CPU tends to stay around 53c when sitting in its base, and idles at 40c.

Fan is very well behaved, comes on at low speed when 68 degrees is reached, and then is turned off when cpu reaches 55c again which is a matter of seconds unless its 100% loaded.

Fan only audible in a silent room, smooth airflow noise only.

HDD makes such little noise you can only hear it putting your head to the keyboard.

Start 55c, stop 50c. Fan makes a terrible noise and it runs a lot. To be avoided at all times (I sold it to my boss last week, hurah!).

You're fired. (lol)

Sounds like when of those old Celerons based on the P4.

Actually, I have been made redundant :-). I have known for a while this would happen and am glad it happened. I can now use all my time looking for a new career, hopefully in IT, and still get paid for the next nine months.

BTW It was an old P4 based Celeron. I needed a laptop on short notice and this one was available at the time. Used it for a few months. Lets hope my hearing will recover.

I played around with a Mobile P4 - based toshiba (their old desktop replacement line). The thing would shutdown when loading up the CPU. and that's with copper heatpipes and 2 fans @ high. :roll:

I wonder who would want to replace their desktop with that.... strange.. I would have just put in the highest Pentium M if I were toshiba...

This thread ought to be a Sticky.

I bought a T41 for A$350 via E-Bay. It's a very nice Notebook with T series accessories available, AND RUNS PASSIVELY ALL DAY if you don't max out the CPU.

Only problem, I tried adding a Transend 32Gb SSD with no success. I'm not sure whether to keep trying SSD's for it, or whether these have issues like most Sony's that prevent SSD's from working correctly in them...?

Lenovo T400 with P8700 25W CPU / Radeon 3470

Can run passive, great cooling system, laptop is cool to the touch. Switchable graphics allows you to choose ATI or Intel WITHOUT REBOOTING.

Regardless, the laptop runs passive in low loads. When you apply a large load, the fan character seems more pleasant than most fans.


Unfortunately it has CPU whine which I was unable to fix with RMclock, and I will be returning it. The A/C Adapter also makes noise.
