1. Does anybody have a guess as to the CFM of the exhaust on the Antec Earthwatts 500? It's a standard antec fan 80mm with a yellowish stick on it.

My guess is 34 CFM based on the small antec fan stats from the website.

2. Is the fan speed on this PSU adjustable?

Thanks

The fan is a ADDA AD0812HS-A70GL model. 38.6CFM
Fan speed is thermostatically controlled.

Nice PSU btw. My Antec smartpower or whatever was a piece of $hit and had a blown capacitor or something so I got the Earthwatts. Works great!

Yeah, the Earth Watts are really good PSUs.

If you were concerned about heat in your PSU, what I do for my own, is I would get a high output 80mm or 120mm fan and mount it in the spot directly under your PSU that most case makers put there for exhaust to help create a breeze under your PSU so it gets a little more cool air.

Thanks WR2.

I wanted to know the output of the fan so I could calculate for negative pressure in the case. Since the fan is thermostatically controlled I won't include it in my output numbers unless I seal all misc. air gaps and holes in my case.

Definitely an engineer. Don't worr, I'm one too. :kaola:
You should also determine whether the fan blowing through your CPU heatsink is laminar or turbulent. LOL.
I'm a total dork.

Nope, not an engineer. I'm just trying to learn some stuff to make my new build as efficient as possible. So that laminar/turbulent thing doesn't make any sense. Sorry. :sleep:
