The NCU-2000 has arrived. I couldn't wait to try this thing and I wasn't disappointed. A picture of the monster installed:
The first thing at hand was testing tempuratures. I like CPUburn for these tests but I'm using dual instances of SETI for the first test and then again at the end because it gave me a good look at the difference the NCU-2000 makes over the Shuttle's ICE cooler it is replacing. I've been running dual instances of SETI on my 3.0C @ 2.0 ghz with a .9500 Vcore under a passive ICE cooler with a temp of approximately 60C. According to this chart
and this calculator
the CPU should be dissipating a maximum of about 20 watts at these settings. Replacing the ICE cooler with the NCU-2000 and running dual instances of SETI with the same CPU settings nets a max CPU temp of 44C. Big improvement!!
Next I changed the CPU clock and Vcore to 2.49 and 1.1625, respectively, and ran dual instances of CPUburn. Using the same chart and calculator as above the CPU should be dissipating a maximum of close to 38 watts. This netted a max CPU temp of 53C.
Finally, the big test, running dual instances of CPUburn with the CPU at full clock and a Vcore of 1.4000, a maximum dissipation of about 66 watts. This setting netted a punishing 69C, not too practical as a little rise in ambient temps would send it overboard. But wait! What do I care about CPUburn temps? It's not like I'm going to be running CPUburn 24/7. I will, however, be running SETI 24/7. So what are the temps with SETI? A much more comfortable 62C, only slightly above the ICE cooler at 20 watts.
In an ideal open air 21C ambeint it looks like the practical limit of the NCU-2000 is close to 60 watts. Absolutely outstanding!
