I had both my msi 290 gamer twin froze iv coolers off as i curiously wanted to see what job they did on the Tim job plus to re align the thermal pad that was cockeyed. I seen they didn't go nuts with the paste and was really happy with there job when building there cards. I thought I'd may as well try some icd24c paste and it was horrible for temps. I then cleaned it off and used some good Ok trusty as5 (and I don't want to hear how its conductive) the temps were better but not as good as the factory Tim they used. I know as5 needs 200hrs to do its job but I tinted the cooler and gpu and just added a small amount. I put it back together ran it and pulled apart to see how it spread.. It came out perfect with no extra goop hanging over the chip it's self. Did the same application and now I'm just going to see after a few heat/cool cycles before the temps start to drop. I closed up the case and ran heaven 4.0,on max settings run in loop to keep the heat built up. I left the house for an hour and came back and the heat coming out the rear exhaust was nice and hot. Card #1 was max Temp of 94c and the #2 card was at 85-87c. Before I pulled the cards apart they would sit in the low to mid 80's. Do I just need to let the paste cure for the recommended 200 hrs till it drops to where it used to sit or is MSI using a special paste and if so what are they using?
