Passive E6600 overclocked + passive 8800GTS

[bystander]

My recent HR-03 Plus just completed my passive collection. (Well there are still fans and wind tunnel, so it's not that passive )

Specs

CPU: E6600 @ 356*9=3.2Ghz, 1.3125V in BIOS
RAM: Buffalo Firestix PC2-6400 @ 445Mhz 4-4-4-10, 2.15V in BIOS
Video: EVGA Geforce 8800GTS 640MB @ stock
Motherboard: Asus P5B-Deluxe
Drives: NEC DVDRW, Samsung SATA 200Gb, 250GB, 500GB
PSU: Corsair HX520W
Case: Antec P180


Cooling

CPU: Scythe Ninja Rev.B w/ custom spring mounting and ghetto wind tunnel
Video: Thermalright HR-03 Plus

Fans

Top: Nexus Real Silent
Front (behind HD cage): Yateloon D12SL-12
Back: AC Arctic Fan 12
Bottom: Stock Antec 120mm (that came with my old 3700BQE)

Fan configurations:
Fans are controlled automatically by SpeedFan 4.32. Fan speeds depend on both Core0 and Core1. Fans are at 50% at start up, 75% when either core0 or core1 reaches 50C, and 100% when either core0 or core1 reaches 60C. Top, Front, and Back fans share the same config. Bottom fan in HD chamber is hard wired to 5V.

Temperatures

idle:
Case: 42C
CPU: 33C
Core0: 42C
Core1: 40C
GPU: 63C


20 min into Orthos:
Case: 42C
CPU: 50C
Core0: 60C
Core1: 59C
GPU: 60C

20 min into Need For Speed Carbon
Case: 41
CPU: 45
Core0: 55
Core1: 51
GPU: 75

Case, CPU, Core0, Core1 temperatures are read from SpeedFan 4.32. GPU temperature is read from nVidia Monitor.

Nice job, and great temps! Nice to see that 8800 cooled passively is working with good temps

Thanks. I was only trying to see if a passive 8800GTS would work at all, but it turns out it works slightly better than the stock! The stock fan never spin up, so the airflow was just dismal. I figured I would expose the heatsink to case's air flow rather than locking the heat inside the plastic cover.

A nice job of getting a maxed gamer rig about as quiet as could be done.

This may be a good candidate for a Crystal CPUID setup,if you can match your OC setting,and have a middle level that's a mild underclock/undervolt for those times when you need some power--but way less than an OC 6600.

With the fans spinning relative to temps---that could quiet some of the sound when you are not quite pushing this machine

Does Crystal CPUID work with Intel now?
Last time I used it with my A64 and I loved it. But when I tried the change the multi on the E6600, it doesn't do anything. I wanna use it tho.

Also one annoyance is that SpeedFan can't individually control each fan. So if I turn one down, I turn all down (except for the bottom hard wired one).

I really like your build and am especially astouned that 8800gts can be cooled pasively at such relatively low temperatures.

Now lets just hope you beat every record there is in an Urge for Speed Carbon.

try running the fur benchmark - in stability mode.
http://downloads.guru3d.com/download.php?det=1717
set at 32 MSAA and windowed mode, resolution doesn't matter.
Fire up TAT too, and set 1 core to 100% workload. Let it run for 20-30 mins, and report temps.

I've found games to not stress cards that much (!).

[bystander]

Fur: Stability Test, MSAA=32x, Windowed 1024*768
TAT: Core0 idle, Core1 100%
at the same time for 30min

Case: 39C
CPU: 53C
Core0: 58C
Core1: 64C
GPU: 71C

Keep in mind that the fan speeds depend on core temperatures. At this load, the fans are blowing hard at 100%, which is way beyond quiet. In games where cores are at low 50Cs, the fans were only at 75%.

Very economical design, to have it loud and cool when sound from games is overhealming noises from the case and silent when not in use, aka while donwloading and sleeping in the same room with it. Judging from pictures one wouldn't mind sharing the same bed with that sexy design

With that fanduct I'd be hard pressed to call it -passive- tho

[Fans

Top: Nexus Real Silent
Front (behind HD cage): Yateloon D12SL-12
Back: AC Arctic Fan 12
Bottom: Stock Antec 120mm (that came with my old 3700BQE)

If your fans are spinning at more than 1000rpm they probably all sound slightly different.

Using a single brand of fan throughout could help make the PC less obtrusive as all the fans should sound more or less the same then.

Excellent temps on the gpu. The cpu duct also looks very efficient yet for some reason I believe there is some room for improvement on the core temps. Have you tried alternative configurations? How about placing the top fan on the heatsink facing the excaust?

I already have a bunch of other different 120mm fans that are not being used. I need to think twice about buying more

I don't have a measurement yet, but I've tried it before. I think a fan on the heatsink actually didn't affect its temps much, and the case temps would increase a bit. I also wanted to take out the air duct and see if it's actually doing anything useful. I need some free time

[9ra55h0ppaH]

reviving an old thread... but do you have enough clearance between the HR03 and the Ninja to mount a 92/120mm fan? ive got the same motherboard and CPU cooler as you and i cant find any decent measurements to work out if an HR03+fan will fit mounted the same way yours is

[bystander]

The clearance between the two is about 2cm...
Considering most fans are 25mm thick, the answer unfortunately is no

It'll be awesome if there are thin and good fans for that!

I dont' think you could call the ninja passive, there are 2 fans very close by, including one that is ducted to it.

Also, you list a CPU temp and then 2 core temps, which are both about 8C higher than the CPU temp. Is the CPU temp the one in speedfan, and the other temps are reported in Coretemp? Oddly coretemp and speedfan would give me the same CPU temps w/ my old CPU, with my new one neither of them are able to read it (I think I need to update)

I won't defend myself from that

All temperatures were from SpeedFan 4.32. I was surprised that as soon as I installed SpeedFan, my temperatures were already labelled "CPU", "Core 1", "Core 2". According to section 11 in this guide
http://www.tomshardware.com/forum/22174 ... ture-guide
"CPU" is Tcase
"CoreX" is Tjunction
(although I haven't touched any calibration settings yet)

CoreTemp and TAT both show about 3 degrees higher for Core0 and equal for Core1 compared to SpeedFan.

Why not? Hey, I have a heatsink, I mounted a fan to it, but there are 1/4" foam spacers between the fan and the heatsink. Is that passive?

Passive = no fan

When you have a fan ducted to your heatsink, who's sole purpose is venting hot air off of the heatsink and no where else, how can you consider that passive?

All I'm saying is I believe your title to be misleading. You could argue there is a grey area, or that if the fan is not mounted on the heatsink directly, that could be considered passive. But what is causing most of the air to flow through the fins?
