Does my 3080 founders need some tlc?

I think what people are forgetting is that it depends what revision of the 3080 you have, they changed the design end of 2021 so it's hard to just go, use these they will work as it really depends if we are on the same 3080 version.

Next I will try 1.5mm all round and see what that does, whats peoples method of applying the paste? a cross and 4 dots and send it or manually spread it over the entire die?

Spread just gives me peace of mind , also what pads are you using ? Different brands will be different how they compress down even if same thickness

I used gelid ultimate

Right now its on 2.0mm Gelid extreme on everything but the memory and 1.5mm Artic TP-3 on the memory chips, if I open her up again I will go 1.5mm Artic TP-3 all over (all I have left) as the issue seems to be im not getting good contact with the gpu die to the heatsink.
It now idles at 36c (used to be 50c) but will shoot up to 85c and 100c+ hotspot under gaming load. Avowed for example will throttle it instantly if I don't cap the FPS to 60 and or limit the power draw.
Shame I'm only getting the 14c improvement at the bottom end and not the top end under load too, would be bliss.

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.

Guess I wont know until I open it up.

Here are some tips since it's your first go:

Make sure your tools fit the screws perfectly. When the screws are this small, an incorrectly fitted bit can be an easy way to rounding one.

Pay attention to the screw lengths and threads, as some different widely. Get a few magnet trays to keep them in.

If the PCB won't separate from the cooler, double and triple trip check you have removed all of the screws. If you have and it's not budging, do NOT pull the PCB away from the cooler. Always rotate it in place. Some heat from a heat gun/hairdryer can make the separation process effortless.

Religiously use the correct tightening sequence when you put it back together - GPU outwards, doing a few turns on each screw. Screw in the GPU screws corner to opposite corner, in a perpendicular method. Warning: If you go too aggressive on one screw, you can distort/bend the PCB, fracturing things internally and then it's ******.

Some good electronic tweezers will do wonders on the fan cables.

Get isopropyl to clean the GPU, or use something with a high alcohol content. I like to use cheap vodka.

Above all, exercise patience.

Good luck!

Edit: just seen that you've already done this in later replies. I'll get back in my box!

And thats how its running now, but will thermal throttle in game pretty quickly

That's not what gpuz is saying though?
Seems like since the repaste your performance cap reason is power rather than thermals
Also your core clock speed has gone from 1.1ghz to 1.4ghz
