Noctua NH-U9B SE2 CPU Cooler Review

Testing
As I said for testing we will be using our Intel X79 system.

It is made up of the following components.

Processor: Intel Core i7-4960X Extreme Edition
Motherboard: ASUS P9X79 Pro
Video Card: Sapphire R9 290X Vapor-X Tri-X OC
Memory: 16GB Kingston 10th Anniversary
Power: Raidmax RX-1000AE
Storage: 750GB SATA II Drive
Cooling: Noctua NH-U9B SE2
Case: Cooler Master Cosmos II with 5 fans

For testing we will be using the Intel Burn Test with the AVX instruction set. We use this instead of Prime 95 as it will push the processor much harder. We have it set on the maximum setting and let it ruin through 3 passes. This gives us a realistic idea of the temperatures the processor would hit when it is under full load.

Keep in mind this is an Extreme Edition processor. These run much hotter than normal chips so keep that in mind. Since making our change to the Core i7-4960X Extreme Edition we have only tested a handful of air coolers on it so we do not have that much of a comparison. First up is our idle temperatures.

Now for our load test.

The NH-U9B SE2 also comes with two different adapters that will turn down the fan speed. Normally the speed of the fans is around 1750 RPM. When you install the low noise adapter the speed drops down to around 1350 RPM. Finally when you install the ultra low noise adapter the fan speed drops down even more to 1050 RPM. To give you an idea of how these adapters affect performance check out the graph below.
