I wouldn't.

Neither would anyone that would setup this amp outside, or away from the listening area... ...which is what it is sold as, more-so than to be hooked up to a TV sitting next to the couch.

I'm not saying it can't be true, but I find it hard to believe that an 80mm fan @2k rpm is 19db<.

Regardless, I usually use fans that are 10db<.

This is my prefered 120mm

And 80mm

I agree. I have 6 Yamaha pro amps currently in the rack, 3 new P-S series, and three older P series, and I've only been able to get the fans to come on in rare instances on the subwoofer amps, but even then they are staged and come on as needed at the lowest speed required and switch off when the duty cycle of the material reduces enough. Even then they are not that loud. When I used them in the PA, it was rare for the fans to come on max, and I beat the snot out of them, far, far harder than almost any HT person would.

I believe most pro amps use 24v fans.

Really? That's good to know! I'll check out the suggested fans here and see how tolerable they are. Thanks again.
