1 days later temp are worst than they where before repasting ( MX-4 )

Can someone help me im going to loose the screw and rescrew them to see....

Any idea what is the best thermal paste for gpu and cpu?

I have no prob with my cpu temp that i repasted at the same time with the same mx-4 that iused 3 month ago for the 2nd time but the temp where still fine ( i changed the cooler fan...

But the gpu temp are

If its within 1 - 2c from you re-greased i wouldn't worry about it. also your room temperature maybe warmer or the fan speed you used is not the same. something to consider... anyway mx4 is great for gpu's and i would stick with it. gpu's i tend to use the "line" method.

what kind of temps are we talking about and at what fan speed?

I've taken a liking to the baggie on the fingertip spread method for the last few years. Better control of thickness and a lot easier to gauge pressure and control that way. MX-4 is paste of choice for direct die application like a GPU - just stay away from the conducting varieties (due to diodes/etc. being very close by on some GPUS) and diamond varieties due to potential scratches on the die.

Something wrong there, I used MX 4 on my old 7950 although it was a Twin Frozr, temps dropped about 10c under load IIRC. I just applied it with the pea method. Something needs tightening or redoing anyway.

ah crap fixed was sapphire trixx that i let it at fixed fan speed at 30% epic failure ( And epic win for sapphire cooling with 30% fan at 925 boost not going over 90c

with the card getting that hot, i'd say the thickness of your TIM may have heated up and squished out to compensate for the pressure between the die and heatsink. the drop in temp would cause it to contract.
give the screws a bit of a tightening and see if that helps.

so i shouldnt use IC diamond on a GPU? i was about to repaste my cpu/gpu tonight :3 i already picked up some IC diamond. i can run down to microcenter and get something else nbd, but whats the "best" gpu paste.

i dont mean to thread jack but im doing a 7950 as well.

Arctic Silver 5 on both my 69's, better temps than stock "putty" (god only knows what the heck it was!) but you do have a long cure time with AS5...
