I had cleaned his pc with compressed air last week in fact. But it's not the first time I did it, both on my brother's pc, the work computers and my own pc.
I always hold the fans with my fingers before blowing compressed air on them.
Today I spoke to my brother. He told me the pc had been working perfectly. Then last Thursday or Friday he heard a big crackling sound from the tower... but he didn't bother because the sound stopped within a second (sure the fan got jammed) and his pc didn't crash or anything.... so he just continued playing...
He gave me the pc last Sunday because somehow he managed to corrupt the boot.ini
Anyway, I just ran recovery console, bootfix, and all was fine. It was some hours later while defragmenting his 1TB drive that I noticed the top of the tower quite abnormally warm. And then I noticed that the PSU fan was jammed
