Quite possible. EBay atm is a nightmare apparently though. Lots of people selling cards and then getting claims back that it hasn’t arrived.
Recommendation generally is to try FB marketplace so might give that a go
Generally, FBM is okay. You have to deal with the idiot offers and the disappearing acts but I've had most success there.Recommendation generally is to try FB marketplace so might give that a go

Did have one unpleasant incident but mostly good.

I run rFactor 2 and AMS2 in VR with a Valve Index headset. Managed to get a 3070 last week and it's not a huge step up over the 2070S that it replaced. Although I am getting a solid 80 fps in both sims, I had expected a bigger jump in performance!
That's because 3070 is basically 2080Ti level performance - which is great (especially at RRP if you can get it) but not a massive leap over the 2070 Super.Lucas Ayde said:

Looking on CCL, they seem to now have lots of 30XX in stock. At a high price of course...
Yeah, they are mostly all LHR.Miners don't want them and gamers won't pay that!
box also has some cards in stock, also at scalper prices, they have my 3090 for £1000 more than i paid for mine

Anyone here done a thermal pad job on their 80/90 FE?
Still in two minds what to do with my 3090.
I'm messing around with three founders 3090 at the moment and trying different things.Still in two minds what to do with my 3090.
1 of them I have not opened up at all, just added a large cheap heatsink on to the backplate. Using 1mm 12.8 w m/k thermal pads between the outer side of the backplate and the heatsink. Thoughts are that this card has not been opened up and will maintain warranty. With a side intake fan at 3000rpm blowing directly on it, It has reduced the memory t junction temps considerably. Holding 84c at +1400mhz vram when mining, compared to 110c at thermal limit at +200mhz ish
The second one I have removed the factory backplate and replaced the rear nvidia thermal pads only with 1.5mm 12.8 w m/k. I have then added the same heatsink to the backplate but this time I used cheaper 4 w m/k between outside of rear backplate and heatsink. It runs around 8 degrees hotter than the other card. But I think most of that is driven by the fact this second card eats the heat off the first card as the heatsink of the lower card is directly below the intake rear fan of the 2nd 3090. So it is sitting around 92c but still miles better than banging off the 110c limit. I need to swap the two cards around and see if the temperature difference moves to the upper card and thus proves the point.
The third one is awaiting its EKWB vector ltd edition waterblock that arrives tomorrow.
Would I say replacing the thermal pads front and rear and new thermal paste on is worth is? I'd try some other options before I canned my factory warranty. I'd also assess if I had an actual issue that was experience during use, or if I just wanted lower temps.

Thermal pads (you need three of these):

When you say you are still working out what to do with the 3090, what are you thinking and what did you get the card for?

I've done similar on my 3080's (non-FE). The backplate was getting pretty hot which implied thermal pads were good. Popped a heatsink on the back of each and knocked a few more degrees off the memory temps. What kind of hashrate are you seeing at +1400? That's very impressive for a non-invasive mod, I'd definitely be happy with those temps.
Well my options are mine with it or re-sell. I bought it because it should still turn a profit (and my PC mucked up so I couldn't get an 80), but I do love the idea of a 3090 in the rig. The £/MH is pretty poor though.

We have run between 120mh/s and 127.x mh/s
+1000mhz is 120mh/s and that's everything very relaxed with t junction temps right under control.
The 127 mh/s is right on the limit and needs +1750mhz on tbe vram.
I'd just concluded my tests with a single 3090 when a second one arrived so I backed off the first whilst I learned how the second one influenced the heat in the case and so on.
Interestingly the gpu closest to the cpu (I opened that one and changed the internal back plate thermal pads and it had the heat sink but cheaper thermal pads between heatsink and back plate) runs +10°c on the memory temps in direct comparison with identical settings with the card I did not open up. I will replace the outer thermal pads that touch the heatsink with higher quality ones later this week to see if I can get them both to be equally as good.
A nice PHer called Jollysoutherner hooked me up with his spare 3090fe. And it will be water-cooled tomorrow. Be fun to see how that one goes.

Well my 3060 ti has turned up, but not going to use it as it seems it has a lite hashrate which i thought was only with the 3060. i wanted to mine and play games, only got one gpu, can it be bypassed?
I'm guessing it's an AIB?There is no known workaround for the LHR on those models, although they are fine on other coins.

I'm very tempted to try the heatsink method, staggered you had such success. Did you thermal pad the entire back of the heatsink?
With my 3080's I did it to mirror the thermal padding on the other side. Still have some left over but probably not enough
The backplate is a heatspreader and designed to take the small points of heat on the PCB and spread it out over a large surface area and pass to the air. WHen you add an extra heastink, the aim is to help that backplate/heatspreader share all the heat it has over an even larger area. So you put thermal pads all over the same area as the heat sink. The cool looking shape and design of the 3090/90/70 has that line going through it and that is ever so slightly raised compared to the rest of the backplate, so to get the heatsink to touch on as many points as possible you use 1mm thermal pads and dont cover the line/design. That way the heatsink is touching for say 95%+ of the surface area. In the image below you can see the thermal pads that have been put on the card. I then placed the heatsink on top and cable tied it on. I trimmed any excess pad once the heatsink is in place. In terms of why it is working so well, all I would say is that these two gpu sit in anolder fashioned pc case that instead of a glass side panel has a metal panel with a single 140mm intake fan on the side panel that blows directly on the top of the gpus. I have a 3000rpm noctua industrial fan in there and that means that the heatsinks are being ultra blasted with cold air. However my before and after test with the heatsink still had this fan, so its a fair comparison.With my 3080's I did it to mirror the thermal padding on the other side. Still have some left over but probably not enough
Some pics. The last pic just shows the backplate removed and the stock thermal pads. Nothing special here. The second last pic shows a tiny component that EKWB wanted me to add a thermal pad to cover before adding their waterblock. The thermal pads were so fussy and numerous that it took just under 3 hours of constant work to put all the thermal pads on front and rear. THe last one is the EKWB Ltd Edition waterblock on the third 3090.

One of the reasons I point-blank refuse to buy EKWB GPU blocks is that I cannot stand their refusal to provide pre-cut/pre-sized thermal pads. Is that something that's changed this time around or was much of that 3 hours spent cutting them to size?
When I water blocked my 2080 with a Watercool Heatkiller I think starting disassembly to completed assembly only took about 40 minutes. And that also included taking loads of pictures as I went!

I see watercooling as a labour of love. Like spending afternoon washing, polishing and waxing the car. So I just settle in and it takes as long as it itake. Yes you are correct that the time was spent looking at the instructions, locating the tiny component they were saying must be covered, measuring and cutting the thermal pads.

One thing EK is good for is the manifolds they have available for multi card watercool. Here are 4 founders 2080ti. Works well.
As for heatkiller, I have a pair of 2080ti founders pcb cards using heatkiller IV waterblocks. I think their work is top end and easily comparable with EK. Like you say, they were easier to fit :-).
As for the cableties comment, the heatstinks could stay on using the light stick of the thermal pads and gravity due to how they sit in the case but the cable ties was about adding some pressure to push the thermal pads onto the heatsink and clamp them together.
It sounds like you have been modding and messing with PCs for a good while :-).
Cheers
