Sapphire Pulse RX 5700 new thermal pads HEAT problem..

Trietch

Hello,

I have tried to change the thermal paste and memory thermal pads on my RX 5700 Sapphire Pulse but now the core seems to not be cooled.

In 1 sec in load it gets to 105°C..

At first I thought the problem was the thermal paste (too much) but now I think that my pads (1.5mm) are whether too thick or too thin. (When I look at the pads, they touch memory chip)

 

What you guys do you think? Thanks

Right thank you guys.

And do you know any way to slim down the pads? Or do I need to order new ones?

new ones. PAds can be -+0.25mm thick from to roginal. the pads are usually 0.50mm-1mm so buying 0.75mm would be ideal.

That is A LOT of thermal paste in your picture...like 2x too much.

It shouldn't giant pile like that...

You just need a thin layer...like this (this is after removing the cooler).

 

Should've also measured, or checked reviews to find out how thick the thermal pads are, so you know which exact ones to buy.

I can't find the exact thickness of the pads for the Pulse 5700 / 5700XT, but people are saying Sapphire uses 0.75mm thick thermal pads.

Some people were having issues with even using 1mm, but 0.5mm did the trick.

I used 1mm pad and the core temps are okay.

But the memory chips are still really hot.

Maybe will try .5mm, can't find .75mm pads.

When I did the same thing I ripped the original pads to shreds when it came off so I contacted Gamers Nexus and got an answer from Sapphire themselves through Steve

I went for Thermal Grizzly Minus pads and have had great memory temps ever since

 

Edit: Keep in mind that gddr6 runs hot anyways so don't expect to see super low temps from this

Just out of curiosity, what are your junction temps.   Thinking about doing the same on my pulse.   My core is nice and cool but juncture can reach 102c

I refuse to read threads whose author does not know how to remove the caps lock!

~86-90°C in a hot environment, while mining. It is definitely worth changing the pads.

I have a local retailer selling these pads: THERMAL GRIZZLY MINUS PAD 8, 120 Х 20 Х 0.5 MM.

Are they the same thing you got?

How many do I need? (haven't opened the card yet)

True, could be thats why it doesnt make proper contact, i mean it looks like its physically impossible with that much thermal paste. 🤔

The direction tells you... the direction

You need the 1mm ones, 0.5mm is not thick enough

Will the THERMAL GRIZZLY MINUS PAD 8 with a thickness of 2mm squish down to 1mm for that exact same GPU?
