Guerrillas in the Mist said:I've noticed my CPU temp tends to reach 49-52C when I leave my PC idle, which seems pretty high. I'm assuming it gets higher after heavy use. I haven't had it shut down yet due to overheating, even after spending a good number of hours last night on Crysis and Resident Evil 5. I've got a feeling it might be thermal paste-related, as when I removed the heatsink and reapplied it when building, the amount on the CPU looked kinda weedy.
Those are pretty typical temps for the stock intel cooler. I wouldn't be worried about it.
If you wanted to do any overclocking I'd recommend the CoolerMaster Hyper 212+ for $30. Best price to performance of CPU coolers.
