Mosfet Cooling?

Hi all OCForum's users , I was wondering if you might know how I could go about cooling my motherboards mosfet's , I have a heatsink on them already ,and tried an 80mm fan which was running pretty fast ... around 2000rpm or so... and still the mosfet's heatsink is boiling hot , especially after prime95 , I can run 3.8ghz on prime95 for about 5 minutes , but after that all I get is a crash , even adding more voltage to the cpu doesn't fix my problem.
Is there any place that I could maybe get a water cooler for these mosfet's?
My specs are just below ..

aha thanks dude , your phrasing is better than mine I suppose

What kind of heatsink? It may not be having good contact among all the whole group of mosfets.

You could try these:

They are individual heatsinks.

also a water cooler may not be the most cost effective method to go for mosfets, think about how often new chipsets come out and when you will be upgrading your board.
