Nah - me too.
It's why I don't own an ABM even though I love the tone from them. It's also why I'm actually considering the Evo5 at it's stupid price if the fans are actually really quiet / silent at low volumes.
My RM800 is as near as silent as any fan amp I've ever had - that gets used in the house and at gigs. My Mark Bass is a bit louder, but no louder than a PC but I tend to use that at gigs rather than at home because if I'm just sitting and playing then I really don't want any fan noise at all.
In almost all cases there could be better temp control systems, or better venting in the amp so if an amp needs fans then they can run far slower for the same cooling. It really is poor design at this point, and it's a real shame.
