Thermal pads leaking, what to do?

Okay, i got a RX 570 Gigabyte Aorus 4GB.

The backplate has 2 HUGE and THICK thermal pads. One is for the backside of the VRMs, the other, for the backside of the core.
Both seem to be "bleeding".

The GPU hard-crashes at 81*C Core temp, meaning, it reaches 105*C somewhere.

I would presume, if the pads leaked, they are not cooling well.

Currently, the only thermal pads that are available in the shops around, are Grizzly Thermal Pad Minus, and Thermal Pad TC300/550/600.

I would presume, the Grizzly are way better. I need suggestions, on what to do, when i have leaking pads, and how to see if my overheating issue is due to them.

how does a thermal pad leak? :confused:

if the thermal pads are old, replace them. figure out what thickness the OG pads are and buy that thickness replacements.

They "cry/bleed". The oil they have starts leaking. It literally soaked the bottom half of my card. The pads are like 2 year tops old. Same age as the GPU.

Does a GPU really needs a thermal pad on the backplate?

they're seeping non conductive oils from inside them. It's technically fine. You should see the ooze on the back of my X79 board from when I modded a 1U Dynatron cooler to back plate. Still no issues all these years later.

The thing in question is, the GPU started overheating like crazy. Reaches 81*C according to sensors, and hard crashes, because the ASIC temp is like 100*C.

Do i need the thermal pads on the back of the GPU, on the GPU core backside and the backside of the VRMs?

I heard this happens when the thermal pad is too thick for the space where you use it. It starts losing oil when it's getting compressed. Supposedly a thermal pad with exactly the right thickness doesn't lose oil.

I'm not sure how true this is.

They age, overheat and can start leaking.

So your cards runs hot, repaste it, replace leaky pads. They sell them from China for a couple bucks. Same colors and probably even source as those used on retail GPUs, don't dream that they are using some crazy high end thermal pads there. You can buy some better pads, if you believe the marketing, from say Akasa and other more known brands in computer parts shops, some sell these but they cost 10x such as $20 instead of $2 and that's for a 10x10cm piece.

The TCXXX ones are cheap, but the Grizzly ones are hella expensive. Although, they sell them also in 10x200x# sizes, so i guess i can cut them down.

I know that the oil by itself is not an issue. But would a GPU need a thermal pad on the back of it, directly pressing against the PCB and its components (not like VRMs/Memory chips),

Backplates are for show. Many cards sell without backplates.

You need to change the TIM on the GPU die and replace the thermal pads as needed. backplate thermal pads will dissipate heat off the PCB into the place, but tat only works well if the case has good air flow. The backplate thermal pads is not the overheat issue, its mainly your GPU that needs attention more than anything.

Hi,
Yeah I removed my back plates
They do protect the back of the card too but I was just messing around testing and really haven't noticed a difference with or without
But if you have sweating you should remove and redo thermal paste if it does not have cooling fans get a add on air cooler or something.

It's the paste on the GPU die. The pads on the back are whatever. A card with a back plate typically runs the same temp as one without. It acts as a heat spreader. My Gigabyte 1080Ti only had paste on 2/3 of the GPU. I was amazed when I pulled it apart and saw that. If the damn thing wasn't a golden chip, I would have done an RMA just because. Take the cooler off. I'll bet the paste was poorly applied and now that it's aged some, you're seeing bad performance.

you need to replace whatever was already there. Sounds like they've more than just jizzed, they've failed.

+ new TIM. Yes, best bet is liquid metal on GPU chips.

back Plates are 90% protection, 10% head spreading, and only heat spreading if you've got memory on the back of the card.
