cooling the 6800 ultra mosfet

jseber1982 · 05-January-06, 11:26 AM

i have 2 6800 ultras with the dangerden sli setup. Since the block doesnt cover the mosfets, they get too hot to touch. I was playin some games and the fps went way down, and the psu fried, taking out my scsi card lol. I dont know if the psu blew because of the mosfets getting too hot, or if the psu overheated. i had a silverstone650w. i was running the fan on it at half speed. Do any of you have alternate cooling for the mosfets on your watercooling rigs?thanks

Hmm... they didn't mention anything about it in the basic instructons, maybe the PDF version mentions it

I usually chop up old Pentium 200 heatsinks and put them on my MOSFETS. I have easy access to the epoxy required to do this but you can get it online I think.
