I failed applying thermal pad on my Rx480 why?

Hellos guys, im renewing my gpu for this new year and as the title says i didnt goes well....

Yesterday one guy answer me on Discord that applying any thermal pad over the an 5600x CPU, will no matter bucause it is a "IHS product" but it worked properly with the heatsink, maintaining the temp under °60c

But at contrary with my RX480 Rog Strix i puted it all over the chip square and for some reason it didnt work at all making the gpu under load going straight to +°86c

Why?

Where do i start??

1. Thermal pads on CPUs/GPUs are usually no good unless they are Thermal Grizzly Carbonaut pads or PTM pads like PTM7950. If you used the same pad on the 480 die as the memory then thats where you went wrong. You should be using thermalpaste or one of the other pads mentioned. Most people will recommend PTM7950 or Thermalright Heilos which are phase change pads for those applications.

2. The pad you used on the die was too thick so it didnt all compress all the way down and provide good thermal transfer. Regardless of this. The pads you used cant keep up with that amount of heat transfer that comes from a CPU or GPu. Memory chips are another thing but die/ihs applications are different.


even if you cut the pad in pic 3 to size. its still a terrible idea because the pads weren't designed for it and its way too thick. Replace with actual thermal paste or one of the pads mentioned in my post for best results.

Thanks for the answer sir!
 
You can use that temporarily but its not going to last long because it pumps out. Also how thick are the pads you are using on the memory and VRMs? If you still have the old ones. you should measure them or find out how thick they are because if they arent the same size then it could cause further issues.

This is where gap gauges are needed, metric 1s so people dont have to do conversions

OMG its fixed the temps under load are marvelous! yesterday at the instant i entered in the game the gpu diode go fire up. but now is stable
the others thermal pads are 1,5mm in the vrm and 1mm in the memory the older's pads only covered the vrm's not the memories, that i added by myself...

Regarding the chart, I have TP-133 and SYY-157 from Nuomi. The TP-133 is very thin and viscous, very hard to get a good print with it, even when you use excessive amounts. I found SYY-157 to be a few c better than TF7 and much better than TP-133 in regards to thickness and viscosity.
 
I used TF8 on my card, it works well for now. Dunno how long-lasting it is, but I applied it some time ago and for now it works great.

Gotta warm it up a little beforehand though.
