So I thought to myself that our MSI R9 390 Gaming was getting extremely hot. Gaming on COD was seeing 77c and in tomb raider (that game is hard on gpu's) 94c!!!! yes 94c and the game kept crashing upsetting my Mrs and my ears for not fixing the pc.
So i thought maybe the thermal paste is either not applied correct or too little or two much (typical manufacturing errors) So i opened up the card annoyingly breaking MSI's "if removed warrenty void" sticker however i will battle that out if it ever came to a RMA.
This is what i found. Way too much thermal paste the chip was swimming in the stuff. as you can see from the pictures. So i replaced it with IC Diamond (had some kicking about) and well here are the temperature differenced
COD for 20 mins Before 77c after 61c........... 16c lower
Tomb Raider Before 94c after 71c............ 23c lower
Room Ambient 23c on both tests. Case fans all set to 60%
So averaging about 20c lower temps just from changing the Thermal paste. Im tempted to actually email this to MSI and see what they say as i think given that difference in performance that should be looked at in their quality process.
MSI Standard thermal paste.
The standard paste caked all over the heat sink
Ahh there is a GPU under the paste, I also re applied the thermal strip covering the power caps as it was only half covering the top one.
removing the TIM from the side of the chip with a cotton bud.
I went with the "Line" approach due to the GPU not being square
I then decided to check as i though i applied a little to much and confirmed there was a little too much so i cleaned it all off and applied about 20% less again in a line. Here is after i took it off to check
Again checking the HS after applying my own Tim (I cleaned and re applied 20% less) with a slightly longer line due to it missing the corners.
Overall this has made her Machine so much more stable and of course the GPU a lot cooler. Im sure it being IC diamond will knock 2-3c off over standard paste but 23c has to just be due to it acting more like insulator.
Any way thought i would share this in case any one else is having high temps.
