I have a watercooled GTX 260's using a swiftec block which is not full coverage.. Although i have good airflow in my system, I dont feel confident that the VRMS are getting the same quality cooling as they would with the stock cooler.



My phase 2 VRM's get up to 80C when folding@home while my GPU stays at 45C. I plan to keep these cards for over a year.

Is this a safe temp to run VRM's for 24/7 use? what are the limits/specs/MTBF for VRM's on the 65nm GTX 260? Can someone with stock cooling post their VRM temps?

Thanks! that is reassuring... I want to keep these cards for a while and want to know if they will burn out in 6 months after 24/7 use. If nvidia stock cooler lets them get that hot, then im less worried.

well the VRM's on a 4870 can do over 100 degrees C constantly, i think its 110C, not too sure about the ones on a GTX260.

is that pic actually of your card, does yours have the full cover heatsink? if so i wouldnt give it another thought, if they are bare, cool them.

yeah its the website pic but i do have the aluminum VRM coolers (same one as in the picture)... The cards look just like that with all the thermal tape and goodies applied.
