Hey,
I bought this PC in August 2013, and has been very satisfied with it. A few weeks ago, one of my fans started making a lot of noise, and I replaced it a few days ago.
After replacing it, I have had a problem with my computer overheating by doing very simple tasks on my computer, like watching a movie or moving files. If I have my laptops power setting on "power saving", my temperatures stay around 60-70 celcius, until I do something which makes it overheat, but putting it on "high performance" shoots it right up to 90-100 celcius in about 10-15 seconds, without doing any tasks.
I never had this problem before, and I have had my computer run on "high performance" ever since I got it, so I guess I messed something up while exchanging the fan? It is the exact same model, and I have double-checked with tutorials that I did everything correctly about five times.
I can feel that the CPU gets hot really quickly, but at the same time I am also sure that the fan is working.
I have tried to go back to my old fan aswell, as I would rather live with noise than an overheating computer, but the problem persists.
Any ideas of what I have done wrong, or about things to check?
