Can hear CPU RPM change even when set at 100%

[Vertico]

I have an EVGA 780i motherboard, Q6600, and an Arctic Cooler 7 Pro HSF,

In the BIOS I have set the fan speeds manually to 100%. However, once I boot into windows, I can hear the CPU fan periodically change speeds. It gets very annoying.


I have been experiencing some CPU heat issues which makes me think my heatsink isn't working.


Any guesses on why my CPU fan is constantly changing speeds?

Have you still got EIST or C1E enabled?

its annoying that your fan makes noise when the system boots? or that you can hear your rpm of your cpu?

lol!

heat sink is not working? it just sits still how would it not work?

I`ve got the same problem, i have only stock coolers and i can say for sure - it`s something wrong with Q6600 itself. Very annoying, agree. Now I`m looking foward to buy a better cooler.

dragonsprayer, he meant rmp fluctuation (i`ve got +/- 40rmp). You can hear it and it is very annoying, makes me keep some good music on all the time
