It's me that bloody suffers when I put my 845 monos on, the amp are perfectly happy. Only using my summer amp at the moment (Rotel RB06).

I rigged up a large USB fan over the top of the casework that runs from a mains powered USB PSU. Job done.

I'm still new to HiFi so I've been wondering about how hot amps get... I own a couple of Quad 405's and a 909. The 405's get a bit warm, but the 909 gets really warm. I actually called Rob at Quad to ask if it was normal and he said it was... I'm between homes at the moment so don't have a decent system set up yet but within a couple of months I'm going to be frying eggs on the 909, with any luck!
Never underestimate the power of stupid people in large numbers...

How hot your SS amp runs depends on the bias. My (modified) 405-1 runs cooler than my 405-2s.

All my power amps run very hot regardless of the weather. One will put you in hospital if you touch it in the wrong place firmly for more than a second...
