Fans for canopy

[untamed]

For the ultimate quiet fans, I used 220V computer fans - but wired them with standard 110V power. That way, they run at 1/2 speed. They are still effective, but they never reach the speed that generates that "computer fan noise".

The only risk with this approach is that the bearing on the fan must be good, or the 110V won't kick start the fan. While I was warned about this when I purchased them, it has never happened to me.

I agree. I have 2 x 120mm computer fans blowing into the canopy. Granted that your canopy is not 100% air-tight (duh, who's is?), the warm air will find pathes of least resistance to get out of the canopy.

Some advice, only have you fans pulling air into the hood, as they will last longer. If they suck it out, they wont last as long due to the salt and other harsh environment that it sucks through the fan. Mine are strong enough to blow all the warm air out. You can get the 120v ones that can be wired to a switch, or a 12v one with adapters to plug into a wall, etc.

also you can just cut a hole at the top or a slit even in the back as hot air rises, with the positive pressure in the canopy the air will be sucked out naturally.
