I've used my computer for simple browsing, some picture editing, and somewhat intense gaming (League of Legends, Smite, Rift, Minecraft, the usual) and suddenly, on either Saturday or Sunday, my CPU just started getting REALLY hot while gaming and while at idle.
Before the spikes, my idle CPU temp was usually a few degrees below room temp and the fan speed was around 1800 rpm, so everything was about 28 degrees (Celsius of course) and while playing League of Legends, everything might get about 5 degrees hotter so all components would be around 45 degrees, and fan speed would go up about 300 rpm.
After the spikes, idle temps will be 35 degrees and no matter what game, my computer will get a lot hotter; at least 55 degrees, and my CPU fan will almost max out and I can hear it in my case, while my cpu also gets a lot hotter (I saw it hit about 68 earlier).
I've tried all the troubleshooting I could, and I'm quite lost. In all of this, I've also ordered a new heatsink (http://www.newegg.com/Product/Product.aspx?Item=N82E168...) which actually also brings me to a new problem, but I'm going to post this somewhere else more appropriate in the forums.
