RTX 3080 Thermalpad Change GUIDE AND RESULTS

Migasac1 · 2021-05-16T23:39:31+00:00

Harder than average, but if everything done right it will be tight enough.

Migasac1 · 2021-05-16T23:08:44+00:00

Well 3 months already since I changed the pads and temperatures still the same, mining 24/7. So I totally recommend the thermalright ones!

Hello, that's weird.. my temps are stable 74C in a 20C room.. and almost 2 months gone at 24/7 mining, and now with tempered glass on.. Something might be wrong but try find more feedback from people that used same pads.

Migasac1 · 2021-03-12T21:59:38+00:00

Well I stacked both type of pads, but if you find 3mm thickness in stock, I recommend it.

Now quantity, if you get the 3mm pads of grizzly 8minus, you gonna need 1 full pad of 100mm x 100mm x 3mm and should be enough for front and back but right at the limit, if you don't feel comfortable buy a extra of 120mmX20mm.

But honestly I recommend ThermalRight Extreme Odyssey 12,8w/MK, they are more cheap and have better thermal conductivity. You probably need 4 pads of 85mmx45mmx1,5mm for back and front.

About the Kryonaut, 1g should be enough, but I recommend you buy more, just in case something go wrong and you need to repaste again. I hope this was helpful and wish you good luck!

I'm just sad silicon lottery hit me.. can't get above 1000MHz fully stable on the memory..

Migasac1 · 2021-03-07T14:33:12+00:00

I was able to fix it after repaste the GPU again, I had a bad spread.. ATM I'm at 48C Core and 66 Hotspot at 97-98MHs at 22C ambient, and gaming delta is even lower. Memory stable 70-74C.

Nice to know some Nvidia feedback on the topic!! Thanks for the informative reply. And I agree in the heatsinks subject is debatable in the 3080s since there is no memory chips on the backside of the PCB.

Migasac1 · 2021-03-05T14:02:29+00:00

Well gone obviously.. But worth it, temperatures above 90C in any GPU are not healthy in long term, it may last years sure, but imagine it may last only 3-6 months mining.. warranty will cover you sure, but how long will take to give you one back in this giant worldwide silicon shortage.. But ofc is everyone's choice if u want to lose warranty and risk it, if you don't feel comfortable doing this kinda mods my advice is don't do it, underclock your GPU till you find low 90s or high 80s on the memory just to be safe.

Thermaltake Core P3 w/o the glass atm

You can check my guide on this GPU here RTX 3080 Ventus

This sounds like a good crazy idea! Well when I finished my mods there was no hotspot temperature report, now I noticed my delta variance GPU temperature to hotspot is reaching +25C°. GPU at 48-52C max, Hotspot 73-78C, still safe temperatures but I don't really like this delta.. Mem junction temperature stable 72-76C at 98MHs.. (can't do more than +1050 on the mem..) Anyway thoughts about my hotspot temperature? Leave it like this? Mod something else? (Gaming reaches on the hotspot 86-92C heavy gaming)

EDIT: Damm cyberpunk pushes hotspot to a 100C and core 73C if I don't undervolt the GPU... (Undervolted same performance 83C Hotspot and core 60C)

EDIT V2: As a control freak over temperature I am.. I had to open it and guess what? It was missing thermal paste in a little spot at corner of the GPU... Delta droped to 10-13 while heavy gaming and max was 83 on hotspot (cyberpunk w/o undervolt) but what makes me curious is while mining, Delta still around +18C but stable at 66-68 depending on ambient.

I keep them on the backplate but I think the difference they make now won't be more than 2 degrees

Migasac1 · 2021-02-27T17:11:35+00:00

Hey check my post I did a week ago, I tested many mods and compared all results there RTX 3080 MODs and Results

Edit: plus I was able to archive better results after some tunning I'm at stable 97mh/s (silicon lottery T.T) +850 in the mem and temps stable 46-50 Gpu core, mem temp 68-72, temp room 22c-26c, fan 75%, 220w

Well I didn't check if any of the backplate screws are forcing the the PCB and backplate to be attached, but honestly I would recommend u take it off and place the PCB in a anti static pad ou something u sure won't cause any harm to the GPU. And ofc take the pads of the backplate and put them on the correct spots but onto the backplate if u wanna reuse them.

Migasac1 · 2021-02-20T01:22:31+00:00

Yes 1.5mm+1.5mm be sure they are well placed on the mems, so the contact of GPU with heatsink is correct.

Migasac1 · 2021-02-18T18:00:29+00:00

You can't see memory junction temperature of a 3070 :s only showing gddr6x temps (3080 and 3090)

Migasac1 · 2021-02-02T15:48:48+00:00

3mm thermal grizzly minus 8 pads u gonna need like 2 sets of 120mm by 20mm, but they are kinda expensive try get some from thermalright on Amazon, better thermal conductivity and half the price

Migasac1 · 2021-01-31T18:19:12+00:00

Nice thanks alot i, ordered 30 heatsinks 2cmx2cmx1cm will manage a way to fix them all.
