This is what I have:

All these in a cooler master rc690 case with the 3 standard fans + 2 enermax 80 mm fans. All the fans are on low to make as little noise as possible. I have made the following changes to the fan config:

- I moved one of the case's 120mm fans that pushed air in from the sides to push air in from the bottom
- I have 1 80mm fan pushing air out from the top
- 1 80mm pushing air in over the video card.

I have a Zalman CNPS9700 cooling the cpu. The thermal paste is fresh (only applied yesterday) and still hasn'n completed the break in period. The fan speed on the Zalman is set to 1800 RPM (I can't hear it at this level).


Stock temps (all temps are according to coretemp,realtemp and speedfan):

Cores Idle at 34-33 C
Cores Max temp 47 C

Here are my results so far:

1.

CPU 2.66 GHZ (266 x 10) 1.325 V (Vdroop to 1.280 full load)
Memory 889 Mhz 1.8 V

Cores Idle at 34-33
Cores Full Load Max: 57
Case temp is 39 C
Ambient temp is 30 C

2. CPU 3.0 GHZ (300 x 10) 1.375 V (Vdroop to 1.312m full load)
Memory 960 Mhz 2.1V

Cores Idle at 35-34
Cores Full Load: 60
Case temp is 39.

I am testing with prime right now and my full load temps have fallen to 57. Case temp has also fallen to 37 due to the ambient temp falling.

Right now I'm worried about the rather high core temps and the high case temp. I think that this is caused by poor airflow (my poor 80mm fans don't cut it anymore) but I could be wrong. It does seem a bit odd that my cores would idle at a lower temp than the case temp. I wonder why this is the case.....

Right now I'm open to any suggestions/comments so keep em comming.

Edit: I tried setting voltage control to auto and the cpu voltage got set really high (1.48). As far as votlages go I wonder if I could get away with 1.35 or even 1.325...

Yes, You may be able to get voltages that low.
Perhaps even lower, but you just need to test with your CPU.

I have a rather old E6300 running at 3.0Ghz under 1.3v.
Your Stepping is definitely newer so may be able to hit that.

you wont get much higher than what you get now.i only manage to get 3ghz on a insanely 1.525v@BIOS,1.72 idle/load@CPU-Z.

any higher of every voltage just wouldnt let the CPU go higher.its a defect these chips.speed bin as the slowest Core 2

here is my result by the way.nothing impressive.but still very difficult due to the stupid nvidia mobo.

Rivatuner doesn't seem to be working properly with my video card (8800gs). Drivers seem to be buggy too for some reason....

Anyway I've bumped my CPU to 2.7 with default vcore until my temps stabilize a bit and I get a chance to see whether I'm happy or not with what performance I get right now (time to put that COD4 bundled with my vid card to good use)

Still, would anyone have any recomandations when it comes to case fans? I'd really like'em to be as quiet as possible, i've set a zero noise goal for my computer.

Yate Loon fans are dirt cheap though I don't think their the quietest fans. Maybe some foam dampening foam would help if noise is a problem?

that is good idea.but if i were building a pc i will get high performance fan and hook it up to a fan controller.so that adds flexibility when you need the extra cooling.trust me!one day you would want more from it and you need to buy better fans then you will regrat.

left prime95 on overnight.. and as long as the cpu lasts me 2 years im happy, having a low temp helps to stop the cpu from cooking

Ok then, I'll try and see if I can get the CPU to run Prime stable at 3.0 overnight (not that I really need more speed).

What do you think about the memory? I have it running at 960 Mhz @2.1 V but it won't budge any further. Any advice on that?

change the memory multiplier to 1:1 because doesnt matter how much higher you run it at it will be limited by the FSB.so its always better to lower the cpu multiplier to get higher fsb to increase memory subsystem performance.use everest to benchmark the memory and you will see what i mean.
