Interestingly, I extracted the CPU earlier today because it recently reported overheating. Turned out it was time to replace the thermal paste, that sort of turned solid over the years. Those i7 can heat quite a lot. It feels weird to have something so small, costly and powerful in the hand. Like jewelry, but it doesn't (only) looks good, it actually does quite a lot of stuff. Also dismounted, bathed and dried the whole (cheap) aluminium radiator, of course the fan blades, removed former paste leftovers with a mix (drops) of water and toothpaste on the flat side, worked very well. Used one medical sterilized compress to clean the thing, the cloth is made so that it doesn't leaves fibers in the wound. Applied a generous layer of new paste, ran a benchmark and I'm very happy with the temp readings (and, needless to say, the stability) I got. So far, so good !
