Noctua NH-U12P Heatsink Review



The computer I’m testing this out on has the following goodies jammed into it:

  • AMD Athlon 64 X2 3800+ Dual Core Processor, AM2 slot.
  • 3GB of system memory
  • 320GB Western Digital HD
  • Two 120mm Case fans

I checked the temperature of the room, and it was holding steady at 51 degrees Fahrenheit.  I am testing this against the Transformer6 heatsink that usually resides on my processor.  Upon first starting up I saw that the fan was actually very quiet, with very strong airflow to the back side.  It seemed to be living up to its word so far, albeit a little on the ugly side.  I can’t begin to comprehend the reasoning behind making the fan brown and the outer fan casing cream-colored.  But that’s not really the point here is it?  Maybe part of it.

As usual, I let the PC run idle for twenty minutes before I tested its idle temperature.  So I went and grabbed a sandwich and read a little Computer Power User before coming back to check the status.  With background processes running the idle temperature on the cores was a few degrees higher.  So just to be fair I’m going to go with the higher rated temperature for this test.  I was getting a steady 27 degrees Celsius from CORE 0 at this point.  So I turned on SiSandra to load the system and give me a load temperature.

After about twelve minutes the test was done, and I could read the final temperature of the processor.  At full load the temperature of the cores were 30 degrees and 34 degrees.  Even at the load temperature the processor was still quite cool.  Especially compared to the Transformer6’s temperatures of 29 degrees idle and 46 degrees under load.
