Hi guys, I have noticed my 3080 massively dropping its clock speeds during gaming, to dig a little deeper I set the fan speed to 90% and opened Kombuster while GPU-Z was open and the results are attached.
Am I right in thinking the GPU should technically never thermal throttle and should instead be bouncing off the power limit?
The card is 3 year old founders edition, would a re-paste likely fix this issue? The fans are going crazy during gaming and still not keeping the temps under control.

I'd repaste it - at least open up and make sure not dust clogged etc, could also swap mem pads - my 3080 FE ran hot but not that bad!
 
Yeah that's what I figured, just never opened a GPU up before haha, and have nothing to fall back on. Time to watch some YouTube videos I guess, as it's performing like a 3060 at present :(
I just noticed i'm loosing 50% of my clock speed, ouch.

Yeah it looks like it needs repasting , not sure what the throttle on GPU temp is as mine never has gone that high

Didn't enjoy opening it up , especially the tiny clipped fan cables
 
I think it's keeping it's self at 90C GPU temp and 105C hot spot, that must be the safety mechanisms kicking in or something. It boosts to 2000mhz until it reaches either of those, then nose dives the clocks and power draw. I guess I always knew it needed re-pasting, just scared to do it haha, oh well as GaryEats says, lets give it a go!
 
your postimg link has expired so i can't see the temps (imgur is better)

just note that if you're repasting, you have to use thicker thermal paste as pump-out is common, or use ptm7950
changing the memory thermal pads at the same time is also recommended as the FE pads were bad and the ram chips frequently runs >100c

Happy to help you out if local, FE's aren't a nice first card to open. :)

I've replaced the thermal pads on mine noticeably reduced the memory and used syy 157 thermal paste as it's thick less effected by pumping out , been over 3 years now cards still going great no change in temps

Thanks for the kind offer, I have the tools so I will give it a go. Just need to decide what paste and pads to order, and there appears to be a debate on if they should be 2mm or 1.5mm.

THERMAL PAD SIZES ON NVIDIA – GeForce RTX 3080 Founders Edition – THERMALPAD.EU

Guess I wont know until I open it up.

There's two versions of the card, so you'll need to figure out which one it is, opening it up is best way to find out. Good luck, and take your time!
 
It was bought in Feb 2022, so just missed the warranty period haha, oh well.
With it being a 2022 model, I assume I need a mix of 1.5 and 2.0 as shown below?

I used ultimate gelid 1.5mm , after the extreme 2mm didn't work

I still believe they changed something later batches with the 2mm extreme

So a pack of 1.5 and a pack of 2.0 gelid extreme pads are needed. Would MX-6 paste be ok? as it seems reasonably priced and good stock.

Oh thats interesting, I was hoping the 0.5mm difference would just compress and not make any difference in the end.
