Re: [APD] Cooling fans for hoods...

Thank you for the comments folks.

I think for thermostatic control of a fan, I'm going to try this...


hooked up to a 120mm one of these...


with the possibility of connecting second fan at a later date if things are
still too hot.

Now, am I better off having the fan(s) oriented to suck warm air out of the
hood, or blowing cooler air into the hood ?

and that just leaves the woodwork :-o
