Noctua NH-U12P CPU Cooler

Test Setup and Testing Method

Test Setup

The following Test Setup and Method was used:

CPU: Intel Core2Duo E6700 @ 3.33Ghz
Motherboard: XFX 650i Ultra
RAM: 2gb Mushkin XP2-6400 4-4-4-12

HDD: OS - 160gb Hitachi Deskstar SATA II
Power: Zippy 500w
Case: A+ Case Monolize
Graphics Card: Sapphire X1600Pro with Arctic Cooling Accelero S2

OS: Windows Windows Vista

The ambient temperature during testing of the Noctua heatsink was 24.1°C room temperature and the system temperature was 30°C.

Artic Silver 5 was applied onto both of the heatsinks to give as fair a comparison as possible. Please note that as AS5 "cures" (about 200hours and at least 2 cycles), the temps are likely to drop 1-3°C. Due to time constraints neither cooler had this luxury, and this was a fair comparison.

For the testing I had the E6700 clocked both at stock settings of 266 x 10 (2.66GHz) @ 1.3v and 330 x 10 (3.3GHz) @ a fairly high 1.45v to really push the coolers.

Temperatures were logged using CoreTemp monitoring software. Temperatures were checked with a thermal probe and found to be fairly accurate.

For idle temperatures I left the PC for 30mins then recorded the idle temperature every 10 seconds for 5 minutes, making sure I did not use any program that was not already running at windows startup.

For the load temperatures I ran an instance of prime 95 with in-place large FFT's for maximum heat and power consumption, as well as an instance of [email protected] set to take up any spare cycles of the CPU. Once again I left this for 30mins then recorded the temperatures over a 5 minute period.

For comparison I used Intels stock cooler, the Scythe Infinity , Asus's Triton Cooler and Akasa's Revo. Note that for the testing with the Asus Triton 75 testing with a fan I used the same fan as on the Scythe Infiniy for parity and fairness.

Nice one Kempez.. Does that out preform the giant Thermaltake?

Also is there a %age score?Quote

what about getting the NT-H1 on the base and retesting it?

I'd be glad to see what it actually does.

The review was conducted with AS5 to give a fair comparison with all of the other coolers tested. When I install a new test rig next I am sure I could test it tho Quote

No Chance to rerun the test with the Noctua itself and NT-H1 instead of AS5?

I'd think that would be the easiest way
