Sapphire Pulse 5700xt Cleaning and Liquid Metal Application

[Demonic Donut]

Did a little PC maintenance on my wife's computer this morning and wanted to post the results.

 

I pulled the GPU for cleaning and decided to tinker a bit. Everything was quite dusty. We just redid our computer room and made some dust in the process so I knew it would be time. It's been about 6 months since I blew the towers out last.

 

 

Stock thermal pads are 2mm for the backplate and 1mm for under the cooler. Phillips 1 for all screws except the spring bracket for the cooler itself, those are Phillips 0

 

Stock paste application was still wet, bought the card in November 2019. Wiped off easily with paper towels.

 

Washed the cooler with soap and water, dried well. Buffed the cold plate. Cleaned the entire pcb with 91% iso and a soft toothbrush. Cleaned the chips with microfiber cloth and iso. Applied MG Chemicals 419D Conformal Coating to the area around the GPU die and let it dry while I cut new thermal pads. Gelid GP Ultimate 15w 1mm pads were used. Applied TG Conductonaut to die and cold plate. I should have pealed the thermal pads before applying Conductonaut. They were kind of a pain. Tip for those that haven't applied thermal pads before, peal the stiffer side of the plastic off first and leave the soft side to do after applying to the chips.

 

 

Put it all back together and retested with Furmark.

 

All Temps in Celsius, fans at 50% fan speed. OC Setting 2050 @ 1188mV, 20% power limit and 1800mhz memory set.

Overall cooler and a bit faster clocks for the same settings. Fun little project.
