Intel Core 2 Duo Retail Cooler?

Post by elitezoid » Wed Mar 07, 2007 11:10 am

Hi,
Will be buying a Intel Core 2 Duo E6600, I'm not planning to do any overclocking for a while, and will probably instead try to get the cpu to run at default speed on as little voltage as possible.
As it will be the Retail version coming with a heatsink, was wondering what the cooling and noise levels are like, as I will probably use it to start off with?

If not overclocking, the stock cooler is fine. After all, that's what the stock cooler was designed for.

Noise-wise, the CPU fan is not the noisiest thing in my system, the video card fan is. The sound from the CPU fan (E6300) is actually quite tolerable for me. Then again, I am pretty tolerant of noise, so YMMV.

As previous poster said, cooling capacity of the Intel HSF is fine. However, if you are looking for quiet, this HSF will not do it for you. The fan is just too loud. You can cure some of this by playing with the fan's PWM control. If you don't have good flexibility through your BIOS (mine won't let PWM drop below 70%, for example), the SpeedFan software works well. Still, I bet you will be looking to replace this HSF if you are serious about quiet.

Before installing a Ninja. Setting the stock cooling to 800 RPM did fine for me. It's was really quiet in my office space and the temps were completely fine with Orthos/Prime95 running. You might not want to run past the stock voltages though with 800 RPM. But even stock voltages get you pretty far in overclocking.

I have an e6600 with a stock fan/hs. It's silent enough at low RPM but once it starts jacking up it gets loud. Every other fan in the system is quiet including the one in my BFG 8800GTS.

That said once you get everything almost perfectly silent the hard drive starts making sound as it ages :D

I found the stock cooler for e4300 was OK, but the fan had an annoying buzz to it - not loud, but sort of penetrating. So it had to go : )

Plus, when o/c to 2.4ghz, it started to struggle a bit... I presume the e6600 hsf is a bit beefier to start with.

Thanks for the replies!

The motherboard is a Gigabyte GA-965P-DS3P, should be getting the board/cpu tomorrow. To start off I was hoping to undervolt as low as possible (1volt, read a post from a DS3 user who's done this), and if necessary drop the cpu speed, currently I'm only using a AMD 3000+ so it should be a decent improvement, even if underclocked.
So assuming I'll be able to reduce the fan speed to a near silent level the box heatsink should be good enough to start off with?

Also anyone know if speedfan works with this board?

Well got my system built, and thought I'd leave some feedback....

I'm quite impressed with the retail cooler, surprised to see it has a copper core, and looks a decent quality for boxed cooler. However I really don't like the push pins system for mounting, felt concerned that I had to apply too much pressure for the pins to click into place, had images of a crushed cpu core!

When I first fired up the system I was a little concerned to see that the fan wasn't even spinning, the smart fan system in the bios was set to auto and I had to wait for the temps to increase before the fan started.
In terms of noise, well I can't hear it, it's probably the quietest item in the box, essentially it's silent. However this may be because I've underclocked and undervolted, currently running @ 1volt, and a x7 multiplier, giving me 1866Mhz.

Although it still seems allot more responsive than my old single core AMD 3000+, and leaves plenty more to come when I need it.

I’m also impressed with the Gigabyte DS3P board (revision 2), couple of niggles, poorly placed fan headers, currently can’t connect up my exhaust fan, and the northbridge runs hotter than I expected (I assume this is the reason they have included a heatpipe on the DS4 and DQ6), and I can't see any options for reducing chipset and ram voltages.
Still got allot of tweaking to do, but so far so good, didn’t even done a clean install, and that went smoothly!

Has anyone done some measurements on the retail core 2 duo cooler? Or maybe a link to an article with a thorough test? I just got myself an E6400 and I'm a bit disappointed with my ninja.

I forgot to record the readings form the stock cooler, but I have a strong suspicion that the stock cooler was quite on par. Right now my ninja shows 42 degrees idle (32 - 34 for each core), and about 58 degrees on full load with Intel TAT. The measurements were done with Speedfan 3.42 and the readings are from the sensor in the middle. I think the Intel cooler was actually better at full load.

And yes, I've read a lot of threads about the ninja here. Mine is rev. A mounted with a bracket on the back. I reseated it and applied thermal compound once more, and this is as good as I can get it to perform :( I wonder if I should go back to the stock cooler.

That does seem a bit warm for a ninja... I've an overclocked a64 (3200+ @ 2.4ghz), with ninja - passive, with those kind of temps.

Are you using the ninja fan? How is the case airflow?

Zenith, I agree your temps are similar to what you can get with the retail Intel HSF. I have an E6300 OC'd to 2.2 GHz and got max temps around 60C using the retail cooler. Now, at such temperatures the retail cooler fan was spinning 2400 RPM and was very loud. What kind of fan is attached to your Ninja? 58C is perfectly safe for your CPU, so if your Ninja does it more quietly than the Intel HSF it is a success. People tend to measure cooler performance backwards. The goal is not to get the lowest possible temperatures -- it is to get a specific temperature with the lowest possible noise.

I have Nexus 12cm fan attached to the Ninja which blows through it. Opposite to it, it the rear, I have 12cm Papst fan running at quite low speed, I would guess 1200 - 1500 rpm. Also a Seasonic S12 PSU. In front a have a pretty silent 92mm Nexus fan and 3 suspended Samsung drives.

The Ninja's heatpipes are only mildly warm to touch at full load. I did undervolt the CPU to 1.185V, and now the maximum CPU temp is 50.5C, as shown in speedfan. What's interesting is that the maximum temperature for one of the cores is around 43 - 44C (in TAT).

System temperature on idle is 38C, and both cores on idle are on 31C.

I've investigated this a bit more, and I'm more and more convinced that the readings might not be entirely correct. Probably speedfan reports a bit too high temps.

My motherboard is Asus P5B-Plus, btw with latest BIOS.

I think I'll leave it as it is. As jessekopelman noted, I probably tend to measure it backwards ;)

Another possibilities is that your heat sink base is not planar or your cpu:s hs is not planar. It's quite common that those are not. And when people have leveled those temp drops have been in some cases over 10 *C

Just remember that the "CPU" reading in SpeedFan is from a motherboard sensor of indeterminate placement. With version 3.42, SpeedFan can also read the individual core temps from inside the chip -- the same readings TAT uses. There will be a slight variation with TAT due to sample timing (it tends to be ~ 1 deg on my machine). I would rather go by the internal temperature readings, as, again, who knows where that MB sensor actually is. The funny thing is that on my machine the SpeedFan CPU temperatures are far lower than the internal core temperatures. I can have a core at over 60C and CPU is still reading in the low 50s. The consistency you will get across platforms (assuming they all use C2D, but different motherboards) is another reason to go with the internal core temperatures over MB sensors.
