Just got Noctua NH U12P 1366

[appplejack]

Just installed this heat sink.
I mounted the fan on the heat sink and was wondering which side of the fan I should put against the heatsink. I took two pictures but don't know how to include them here.
How much temperature is this heat sink supposed to drop? I used to use stock heat sink for Core i7 920. Please let me know. Thank you. It was around 30C before installing it and now it's around 25C for me.

The side of the fan with the bars goes against the heatsink. That will push air through the HSF.

Is that at idle? If so it sounds about right. You're never going to get better than ambient, and even the best air coolers won't do that.

Aftermarket coolers start doing their best work once you throw a load on them.

Yeah- like steve said-, run a stress test and see what the load temps are- that will be the greatest drop from stock cooling.

There I just uploaded ths images. I thought the arrows on the fan indicate the air flow so that's how I installed in my system.
As for the temperature.
It was around 23 as soon as installed and checked the Health Status at BIOS.
I've been running it in Vista X64 Ultimate for about an hour and the CPU temperature is fluctuating between 26 and 29.
The system temperature is 34.
I'm goolgling for stress test. You guys got any recommendation?

Thanks

Prime 95 is a classic, also OCCT. Could use IntelBurnTest even. They all put large amounts of load on the CPU.

[appplejack]

Thanks. I've been running Prime 95 for awhile tonight without any overclocking. The CPU temp is 42C and System temp is going between 31 and 32. I'm going to overclock the CPU after reading some threads here and there to be more accurate. What's your recommended CPU and System temperature after overclocking?

[Eagle Eye]

Do you have a the dual fan setup on that? Maybe we could get shot from a bit of distance, I love noctua and probably would have gone with the LGA775 version had Thermalright not been around.

I have EVGA 58 mainboard. There's a main board heat sink near the cpu. I think I can put another fan but I might have to trim the plastic in order to make it fit. Got any other idea? I don't know if it is a good idea though.
I will upload more shots tomorrow.
Thanks.

Not always true... I've got some that don't work that way. Apparently there isn't an industry standard.

Yep, go by the airflow indication on the fan body.
