After reading alot of good reviews of almost all of your CPU-cooler i decided to go for an Hyper TX3 to replace my stock intel cooler on my i5 750 to get the sound level down in my case. The CPU is not overclocked and was keept at around 43 degrees with the stock cooler, after installing the TX3 it droped to 38 wich i am very happy with! But my biggest disapointment is the sound this thing makes, in idle it is working at 2000 RPM and makes more noise then the intel stock cooler did, on a heavy load it ramps up to around 2600 RPM. Considering the fans working spectrum is 800-2800 RPM it seems like my fan is working very hard?
My goal with buying this cooler was to lower the noise wich i did not achieve. I might also add that the case is very well ventilated with 2 120 mm fans and one 140 mm. Is it normal for the TX3 fan to be working this hard to keep an CPU at stock speeds cool or is something wrong here?
Any answer would be apriciated //Erik
Here is a pic of the fan speed and CPU:
