So basically, a few weeks ago I changed my thermal paste on my rog strix scar 2 but after that my gpu started to behave abnormally like it stayed on 139MHz when it should at 1443MHz on idle. I opened it up again and saw that the film covering the transistors the gpu dye was not in the proper place. The thermal paste was in between the transistors on the dye. I used isopropyl alcohol with a tissue to remove it as much as I could but it didnt work.
I have a question that am I correct that the thermal paste is the reason my gpu is not working properly and how can I remove the thermal paste like should I use a toothbrush or something?
