Could anyone give me an idea of the "normal" fan speeds for the rMBP 10,1 at idle please? I've recently noticed a slight fan noise when the Mac is at idle and showing temps of 43-44 C. It wasn't there previously. I've installed SMCFanControl and it shows speeds of 2150-2160, which seems a bit high. My Mac is going in to Apple at weekend for possible screen replacement (image retention) and a creaky hinge. Maybe they could clean it out while they're doing that? Thanks.
