IGP: Enabled (idle in desktop)
No Overclock
HT: On
Turbo: On (so 3.7GHz with all cores loaded)
Ambient temp: ~20°C
TIM: Arctic Cooling MX-2
This is the 'black' Megahalems - it has some kind of stupid powder coating on it.
The fan is a Noctua NF-S12B on the motherboards auto controller (~650rpm at full load).
Temperature at full load: 58°C, 64°C, 68°C, 66°C
I was expecting better, but then every time I buy a large and expensive cooler they seems to perform like rubbish.
What do you guys think?

Re: Megahalems + i7-3770 Temperatures
Assuming you're running IntelBurnTest or something similar as a load test, those temperatures are about what I'd expect for an IB CPU, particularly with a relatively slow fan like that.

1. That is higher than I would like. But it is tolerable if your regular day to day, non-benchmark temps are reasonable. What temp does it usually run when you are not stressing it.
2. 650rpm is pretty slow, why not add a second fan. In fact why not try two Nexus 120mm fans,
3. Try reseating the cooler and use a TIM that doesn't require a break in period.
4. 58-66 C is well below the 110C that these chips are designed for. 48 - 56C when not loaded, isn't that bad. And the 3770 has a reputation for running hot because of poor heat transfer from the chip to its casing. See:

5. It would be much worse with the stock cooler.

What's the core idle temps when your ambient is 20C?
Re: Megahalems + i7-3770 Temperatures
Try this cheap trick to get a few more degrees of cooling. Please let us know if it helps:

22-33°C (it fluctuates rapidly, apparently normal for this proc) at 19.5°C ambientCA_Steve wrote:What's the core idle temps when your ambient is 20C?
The fan runs at ~250rpm during idle.
I need a picture of what you're proposing. You mean basically turning the heatsink into a duct by blanking the sides?ces wrote:Try this cheap trick to get a few more degrees of cooling. Please let us know if it helps:
