Please help me here. I have a digital thremometer with the wire taped inside the heatsink of my CPU. After about 2 hours of Warcraft 3, the temp goes up to 53 degrees Celsius! That's over 120 Fahrenheit. Is this ok? Would I need a super fricking fan that cost more than my $100 CPU? My case already has two built-in fans blowing in from the front and out through the back. Since I am measuring the temp on the heatsink, I am guessing the actual CPU is a bit hotter. Any one's opinion here?
