After 2-weeks' ownership of my MSI Gaming X, I noticed higher than usual fan speed and very high hot-spot temps. Temps were far cooler last-week, so I contacted the reseller who informed me that 110deg temps were "normal". Anyway, after clarifying with MSI about the tamper-sticker I decided to replace the thermal-paste with Kryonaut. MSI said that removing the tamper-sticker does NOT void warranty, but will result in MSI inspecting any returned cards for "user damage", should it ever need RMA. They also said that I could return the card to them for repair/replacment, but it would take 4-6. As the card is a good-one in terms of overclocking, I did not want to risk having it replaced.
Stock paste after 2-weeks'
After replacing with Kryonaut
My card is installed within an MATX case, so not the best airflow. Paste-replacement has given a worthwhile drop in edge-temps, plus a huge drop for the hot-spot.
*Before: 79deg Edge, 111deg Hot-spot
*After: 75deg Edge, 93deg Hot-spot
Wins of -4deg and -18deg respectively. The gap would have been even bigger had the card not been throttling at 111deg.
Anyway, I will keep a close eye on temps to see whether the issue reoccurs. If it does then I will perform the washer-mod, as I supect poor clamping-pressure rather than poor OEM paste.
