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 280X Toxic
Memory: 16GB Kingston 10th Anniversary
Power: Raidmax RX-1000AE
Storage: 750GB SATA II Drive
Cooling: Enermax ETS-T40 White Cluster
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 are our idle temperatures.
Now for our load test.
As you can see the ETS-T40 did not do very well. While it did keep our processor within the thermal maximum, the other coolers we tested did a much better job.
The included fan actually has different speed settings that can be changed on the inside of the fan. You can select from 800 – 1500 RPM, 800 – 1800 RPM and 800 – 2200 RPM.
I tested the ETS-T40 on the two highest settings.
As you can see there is only a slight difference is performance.
