Hello, first of all, sorry if I've posted in the wrong place. I've been having some serious problems with my Motherboard / CPU overheating. My (What I presume to be my northbridge) goes up to 100 Degrees and then my computer cuts out without a BSoD or any warning.
While idle my computer is fine, however when I play games such as Battle Field: 3 I have issues with it. It used to happen on Counter Strike: Source but since the installation of a 120mm fan it seemed to have stopped on it / being very occasional. I've put new thermal paste in with a couple of degrees difference, nothing particularly helpful.
I have another 120mm fan however if I put it into my case it has to go on one of the sides, which I always have open. When putting it there and having the side on the computer gets too hot and actually is higher than if I didn't have the fan there at all.
Any suggestions of what I should do? I currently do not have the money to get a new motherboard so that's out of the question for me at this time.
