The PCI fan on my 5,1 MP with 5870 revs up to about 2k rpm every single time I start my computer. Then it slows down to the regular 800...It sort of starts at about 2k and then over about a minute it slows down to regular levels. This started to happen about a month ago, and since I rarely shut down my computer (most of the times sleeps) I didn't really pay attention to it. I had gt120 in slot two for about a week now, but that revving (which is pretty loud at the beginning) was happening prior to that. Nothing (as far as I can tell) appears broken on the computer. The performance & video card performance is exactly the same as it was since day one, just the revving up during boot is somewhat new. Anyone with the same issue? It this normal? Should I reset SMC + pram/vram? thx, a.
