Noctua NH-U9B SE2 CPU Cooler - Testing:

For Intel (LGA1336) testing we will be using the Intel Core i7 920 CPU, which produces 130 Watts of heat. This could be considered a mid-range processor, and while most Dual-Core processors produce ~50-80 Watts of heat, this should give you a pretty accurate estimate of what type of temperatures a cooler will provide you with.

For both AMD and Intel testing, we have taken all temperatures using CoreTemp v.0.99.4. CoreTemp takes a temperature from the CPU core, and allows for much more uniform results across different motherboard and CPU platforms. These temperatures may seem higher than other temperature recordings; because chances are they are taking temperature recordings using the diode underneath the CPU, which isn't able to be as accurate, and can really fluctuate between different brands of motherboards.

For all tests we are using the Highspeed PC Top Deck Tech Station , and we are using no additional cooling in our testing. All temperatures are recorded in a controlled environment that is set to 23 degrees Celsius (73.4 Fahrenheit) to provide fair results between coolers.

For all tests we use Arctic Cooling MX-2 High-Performance Thermal Compound (Paste), We use the same thermal paste in all our testing so that we can keep our results consistent. If a cooler is shipped with thermal paste pre-applied, it will be removed and we will re-apply it with Arctic Cooling MX-2 to provide fair results.

 

Intel Test System:

 

For our testing of the Noctua NH-U9B SE2 cooler we have tested the cooler with 2 fans while running at full speeds (1600 RPM) as well as with the U.L.N.A fan adapter that slows the fans down to 1000 RPM. Included with the Noctua NH-U9B SE2 is another set of fan adapters that allow you to run the fans at 1300 RPM (results not included in our charts).

So the first test isn't anything too mind-blowing, however you need to remember that this heatsink is significantly smaller than most of the others we've tested and the fans are running at their lowest settings and generating virtually no noise. Our CPU is generating 130 Watts of heat which is pretty much one of the hottest CPU's available yet the NH-U9B SE2 was able to keep up and still provide better results than the noisy stock cooler. If you were running a ~75 Watt CPU with the two included fans you would be very happy with the results and the lack of noise.

At full speed the two fans on the Noctua NH-U9B SE2 were able to put us some very decent numbers when you consider the smaller size of the heatsink of the NH-U9B SE2. These results are very interesting seeing as most of the coolers we are testing it against in the next chart have significantly larger heatsinks yet the NH-U9B SE2 was able to keep up (and in some cases outperform). Overall I'd say these results are very good for a cooler of this size.

So the results are in and I think the NH-U9B SE2 has done very well for a smaller cooler. Most of the coolers on our chart have much larger heatsinks so the fact that the NH-U9B SE2 was able to keep up is impressive. Even at the lowest speeds on a toasty 130 Watt CPU the NH-U9B SE2 was able to improve cooling performance over stock cooling (and do it much more quietly).
