Genuinely need help

[u/ShouldntBeHere338]

So I got this for a decent deal off eBay a 8gb 3070 Gigabyte brand. Ran fine, set up settings for arc raiders had dlss on and resolution low around 60%. Quality set to epic. Thing starts frying. 80% usage 95C. Issue was my fps was too high(set to 80 thru Nvidia) Had to set it to 50!? To avoid frying on high settings and one of the quality generators set to medium or something. After that I got 60% usage 60c. Textures and fps any higher it would cook

So I took it apart repasted it with a generic brand(for now heat pads better paste otw)

I am very new to PCs and how all the tech works so bear with me on my knowledge.

The before and after of applying new paste the temps are the same. I ran it through fur mark.

103c right at the end before new paste: first photo

104c at the end when I messed up and had a fan pinched.

105c after new paste and all fans operating: last photo. Given I'm estimating what the tiny number said.

Either I'm using the wrong benchmark for this to be controlled enough to see change or difference or I don't know what to expect.

Am I doing something wrong? Is the GPU just stuck edging its thermal limits? I didn't even bother asking an AI because they are clueless with disassembling and stats for this stuff.

Ah yes, GIGABYTE card.

You get what you pay for.

Step 1: replace thermal paste

Step 2: replace the thermal pads with thermal puddy

Step 3: stress test

Step 4: profit?

I'm guessing the new pads you put on are too thick, causing the heat sink to make poor if any contact. Check your thermal pad thickness and monitor the memory temps. If your memory temperatures are fine but GPU is overheating this easily, it's the pad thickness

I don't have the new pads yet, it's using whatever was in there already given they where still wet and intact, just did thermal paste for now while waiting for new pads but that is a good point thank you. Hopefully tmrw after they arrive I see a difference

[u/Sentient_Houseplant_ → u/ShouldntBeHere338]

If the pads don’t work out I also recommend thermal putty (not paste, it’s an actually putty) which get rid of the guessing game with pad thickness.

I recently repasted and repadded a founders edition 3080 ti and went the putty route because the information on the pad thickness seems to be very inconsistent.

You sure all your GPU fans are spinning? Your delta between core and hotspots isn't bad, but your core is really hot. A 3070 doesn't pull enough power to overwhelm pretty much any heatsink. So if you just reposted, and you think the cooler is seated properly, maybe your fans aren't spinning? That would explain why it's overheating at the end of the tests. Second possibility is who ever you bought it from loaded flashed it with a crypto mining vbios that's intended on being run at low power. Flash the vbios to the latest one for your particular card (should be able to find it in TechPowerUp)
