Hi,
I just bought a CM Hyper 212 evo to substitute for my stock heatsink that came with the processor. When I installed it I get some text saying 'CPU Fan Error, Press F1 for setup'. I don't know whether I've installed the cooler wrong, although I am fairly sure I haven't, or if there is some compatibility issues... Can someone help?! The processor is an i7 2700k if that helps

That's typically due to a CPU fan header having nothing plugged into it.

Probably have incorrectly installed the CPU fan. Check where you have it plugged in and make sure you're correctly hitting all three pins.

Yes I bought Hyper 212 evo with the pc, but I got the same error, so I assume it was faulty, so I sent it back and got a new one. I have the stock heatsink, but it's loud and annoying

I bought all the parts and built it myself just over a week ago.

You should be fine as long as the CPU fan is actually spinning. If the fan should die, you wouldn't have any immediate indicator that it had done so, and your PC might start overheating and shutting down unexpectedly thanks to reaching the TJ Max.

If you can confirm that the problem goes away when you plug a different fan into the same CPU Fan header, then you have isolated the problem to the fan itself.

Are you upgrading a pre-built machine? When I replaced the case of a Dell computer several years ago in order to get a third party heatsink installed, I'd always get a screen before boot indicating that the front panel components changed, and I would have to press F1 to continue booting.
