I have an Intel i5 2500 (not K version) I just opened the case (ofcourse with pc shut down) I blew all the dust out of the stock heatsink. Now this is a heatsink with those white things at each corner wich you have to push in. I put it in again, but my computer would shut itself down as soon at Windows had to load. Now I am pretty certain I put it in well, after fiddling around more. Now it starts just fine but my idle temps are 40c all of a sudden, this is certainly not right. I DID break one of these on one of the corners in the process, only the black part that's stuck between the white piece of plastic:
Now I could get a whole new heatsink (Cooler Master Hyper 212 Plus) if I wanted, was planning to buy one anyway. But I worry, Maybe it won't fit.
Anyways, what could this temp rise be? That broken part? Because usually it was 30c idle, now it's around 40.
