You have been most helpful and friendly - thanks!
I dismounted the fan, even though I could not notice any dust before. Heat sink was not totally clean. The computer was for a short while in the kitchen, maybe thats why. Nothing was blocking, but still heat transfer could improve. I think it helped a little. The curve is not that steep up to 85 degrees, where I believe that the prformance drops significantly. Temp just reaches 85, and stays up there just sporadically, curve goes down a little (maybe 1 second), then up. Before it went up, was flat for 10 seconds, then fell down for a second.
I can play Battlefield 2!
If I am not imagining this time, it is rly important to have the heat sink totally clean, not just from dust, because there is no margin. The heat sink barely makes it. If the swedish summer will be fine cooling will not be enough, there will be no gaming, but I will be busy swimming anyway
Thanks again h3llr3is3r, have a nice weekend you too:)
