PWMIC Cooling - Commercial or DIY Solutions?

I'm looking for a way to cool this without "jolly rigging" an 80mm fan somewhere between my TT Big Typhoon and my IDE cables. Has anyone tried adding a heatsink, either passive or cooling? I don't mind spending money on something that will work, or DIY (do it yourself) type stuff is fine too.

 

Something like this: http://www.case-mod.com/store/cooler-maste...blue-p-947.html

 

Or maybe a DIY tutorial.

Your best bet is a fan blowing on them. You can mount HS's on it but the sensor is not within the MOFSETs so even if you are cooling it a little better the lower temps prolly won't register.

i did the same thing, didnt decrease temps in sensors obviously because they dont measure them on there

 

i thought i WAS cooling the mofsets but thats something different

 

but hey zeimbo, i see you have the 3 inline, what is the fourth!? i have enough aluminum to make a forth, but looking back and forth at my board, i cannot find a fourth 'R60'...

 

EDIT and for things that small, the AS5 will be plenty to hold it on without being too permanant.

my fourth one at the bottom is for my pwmic. they are all just thermaltaped on, surprising the as5 wouldnt hold them on there well, which kinda worked out because i was worried that it would possibly jump some of the circuitry due to its conductive nature. so you are correct, its the 3 mosfets and the pwmic that i have the tweakmonster bga sinks on. those and my silencer 6 rev. 2 helped get my 6600gt to 631/1240.

Hey everyone, this is my first post here but I thought I would share my DIY solution,

its total overkill but it keeps the pwmic chip almost at ambient temps, the sensor doesnt reflect this but a direct reading of the heatsink does. its not finished yet, still need to do somthing with the center hub but it works for now!
