So after some time since lapping both sides of the IHS and bottom of the H70 pump i was getting some heat spikes. I removed the IHS and saw that there was a large round circle of missing TIM in the center of the chip. Seems that something went wrong. After thinking about it and reading and talking with Cakewalk about his thread for removing and lapping the IHS ive decided to remove the IHS completely. My H70 now sits directly on the chip. It was pretty scary at first. I know other cards/models are shipped without it so i figured what the heck. I was most carefull when placing the pump to the chip. I tried to apply equal pressure when doing it so i did crush or crack the chip by rolling the pump incorrectly on it. I also used a different thermal paste. This time i went with MX4, this is a wonderfull paste btw, so smooth and easy to apply, much easier than AS5 i had used before. Overall it was very easy to do and most pleased with the results.
So heres the goods. NO MORE TEMP SPIKES, WOOT. I have seen the temp drop to 19c. Thats right, i said NINTEEN DEGREES on a overclocked GTX 580. I have hear of noone getting temps this low ever with a oc 580 GTX. It may not keep the max temps as low as true watercooling but idle temps are much better than anything ive seen to date. So from what the card was shipped to me stock to where i sit now, well its amazing to say the least. Stock idle temps were 34-36c and i could get 78-86c while benchmarking, temps are even higher if i was overclocking. Now Idle temps are 19-24c and max temps are 48c (highest ive seen yet). thats 17c difference to the extreme on lows and 40c+ better on load temps on the extreme side.
I have done alot to this card since purchase and at this point am not sure what else i can do to get it running cooler for everyday use. Ive can idle in the teens and my load temps are not much higher than what alot of other 580 gtx cards idle at. At this point im going to savor the victory and when the next lineup of cards comes near ill start to see what i can do to mod the protection off the card and really open this thing up. Overvolt protection.....GONE, lol. With temps like this and coming into subzero temps for winter im going to benchmark the snot out of this beast. Ill include a pic of my latest temps. The max temp is after a night of Skyrim on ultra settings and 1080p. Lows were what i woke up to after leaving the computer on all night while i slept. This pic was taken about 16 hours after completeing the mod.
Enjoy and hope you like
