Well I bought a new PC, but I didn't buy a 3rd party cooler for my CPU. Where I live in the summer It gets to about to 31 degrees Celsius. So when I play a game like Thief the temperature gets to 76 degrees Celsius. I checked the some sites and it says that my Intel 4670k (not overclocked) CPU should run at 72 degrees optimally. So tell me should I buy a cooler or is it not worth it? If i should please suggest some models and I wont buy a water cooling system.
