Test System Setup
To see our testing methodology and to find out what goes into making our charts, please refer to our CPU Cooler Testing and Methodology article for that information.
60.25 degrees does not seem all that great, but remember back to that 84W TDP. Considering this is the stock run of the 4770K and it is 84W, we feel they played it safe with that TDP. This is considerably better than what the stock cooler offered, and is using essentially the same space. We feel this result is actually pretty good for this design.
There is no way of putting lipstick on this pig, the 86 degree result here is pretty poor for what we see others do in this chart. The thing is though, this is like one of maybe three coolers of this size we have ever tested. Considering most others including the NH-L9i would not cope with what the NH-L9x65 is capable of, that in itself says a lot; since we were pumping near 100W to it at this time.
Noise Level Results
For our stock run in the testing, we gave the fans 7.5V as we always do, and at this time we found the fan to be spinning at 1800 RPM for the duration of that test. A foot away from the cooler, the meter showed us just 26dB at this time.
The fan does spool up to 2550 RPM delivering a more audible 36dB of noise. Of course, this is not with the PWM controlling it, and you always have the option to use the Low Noise Adapter as well.
