Well, my friend gave me 3 days ago a cooler that he didn't use anymore. So, i installed it, and put him inside my CPU. Today, while i was playing Witcher 2, it shut down once. I thought it was because of the game and stopped playing it. Now, 30 mins ago, i was just browsing in steam and it suddenly shut down again. Is it possible its because my motherboard can't handle 2 coolers or it is another factor? If it is the cooler, lowering his speed would solve the problem?
