hi everyone

I want to build this amp and I'm wondering that can I use this heatsink for each channel mosfets?

fans details :
The breeze presses : 39 CFM
The fan turns soon : 3200rpm
Fan size : 80*80*25mm

(1 heatsink for 4 transistors of each channel)

btw : with fan of course
 
Heatsinks for audio amps are almost always specified as degrees Celcius (or Kelvin) per Watt. This gives the temperature rise for the amount of energy dissipated. For the big bad boy above you want something that is less than 1 K/W. Cubic feet per minute and revolutions per minute doesn't answer this question. My guess would be "no." It seems way too small, even with a fan attached. These pictures shows how these things are usually done.
