Mosfet heatsink size recommendations

[Spewn]

I've got an old socket 360 heatsink that I had nothing to do with so I cut it up. Problem is, the fins are *just* a bit too big to use 3 fins per MOSFET. 2 is a bit smaller, but not a lot smaller. Think it'll still be sufficient to help cool them? They don't get *that* hot(they're not super hot, like they won't burn me, even after running prime95 for a couple of hours, barton 2500+@[email protected], but they are hot for sure). I don't wanna waste my time epoxying them on if I could do better for cheaper, but if these'll do the job since I've already got 'em cut up I might as well use 'em.

I just cut an old sink, too. I cant say I have noticed any increase in stability, but I had none in the 1st place. Those suckers just get so damn hot I wanted to cool them off.

Exactly my line of thinking. If it gets hot, cool it off
