Would this work for the evga series or is their PCB design too different?

This guy got 5c drop using this:

If that's an XC3, your backplate is thinner, which means less soaking before it's heatsinked out.  You also have thicker heatsinks.  So it actually makes sense your temps are lower.  But, I also haven't tested mining at all (because I have no interest in it) since doing the paste.  The 84C Junction was before I did paste or even redid the thermal pads with the higher transfer ones.
 
As far as securing it, you can always do what I did, buy some thermal-taped small heatsinks (or buy small heatsinks & some thermal tape) and outline the thermal pasted heatsink area with them so it can't move.  Simple but effective.
 
Glad you're seeing good results, one of these days I'll do some retesting with how I have stuff setup now just to see if there's any further difference in temps, but with my highest Mem temp on the iCX sensors being in the 50s with 2 of them in the 40s, under a longer stress test, I'm pretty happy with things as they are.  Still plan on redoing the face-side of the card eventually, but I'll be waiting to do that til it's HydroCopper time.

I didn't mean to imply I was actually getting better temps. From what I've seen, maybe about the same. I was talking junction temps. I think in gaming at 450w I still see a max of 70C or so. Not that much lower than the mining temp.

Should have added more info. My card is actually a Zotac 3090 in a Corsair block. I've been following this thread for ideas on backplate cooling.

My only point originally was just that the thermal paste made a bigger improvement than what I remembered you seeing (junction temp). But I do have a bigger heatsink and maybe the advantage of a completely flat backplate.

Intel has legitimately lost their mind.  Like... seriously.

I question why anyone in their right mind would buy that instead of getting an AMD setup and waiting for the 5900x to be in stock if you're going to drop that much on a CPU.  I really do.  Insanity.
 
I'm just waiting for Amazon to update on when the Asus X570 Hero will actually ship to me so I can order a 3900x and wait for the 5900x to actually exist at MSRP. lol

5.1 Time spy stress test. 20 loops
 
Could not get a 5.2 to pass...

well My temps are sky high because of this!

hwinfo64 crashes it ever time its opened and i have to reset my water pump control to the correct profile so every bench i did with the water pump running at looks like 500-1000 rpm instead of 2000. and fans were all at what ever speed they were at when cpro crashes. I can at least just power down and count to 10 and it comes back or pull the sata power to it and plug it back in the sata power connector is in a real bad spot.

https://www.newegg.com/samsung-4tb-870-evo-series/p/N82E16820147795 - if anyone is looking for a monster-sized SSD that's top quality, that one is 10% off right now ($479 regular price), 4TB & it's not QLC like most of the larger capacity SSDs are.
 
I ordered it.  So my storage is now complete, once everything arrives.  1TB M.2 980 Pro, 2TB M.2 980 Pro, 4TB 870 Evo & a Seagate 10TB HDD.  Going to be very nice only have 4 actual/physical drives instead of 6.  So that's... a lot on just storage LOL $196 on the 1TB M.2, $349 on the 2TB M.2, $431 for the 4TB SATA SSD, & $214 for the 10TB Seagate HDD.
Pretty sure that's more than I'm going to end up spending on CPU+Mobo. lol

Even at that price people would be much better off waiting & getting a 5900x.

I bought the new Gelid thermal pads and have them on the way. I have a 3090 with an Alphacool Waterblock and non active backplate. Core is cool as you would expect under water (39c while mining), but now that the weather and house are warming up the memory junction temps are going up too. I had a sweet spot of 112MH/s while consuming about 250 watts. with an efficiency of ~428KH. My memory junction temps were at about 94c (down from 100c when I was mining at 120MH/s settings). Now my junction temps are creeping back up towards 100c at my formerly very heat efficient settings. My plan was just to throw on the new gelid pads that dissipate at about 12-15 watts on the front AND back. Now I'm thinking something a bit different.
 
I don't have clearance for another fan on the back because it is set up in a vertical position. I am now thinking, why reinstall the aluminum backplate at all- does it really cool anything? What if I add the Gelid thermal pads and then stick small copper heatsinks on top of the thermal pad with no backplate/open to the back. You can't see it anyway and in my head this seems like it would cool them memory on the back even better. The fans you see at the bottom of the case are blowing up towards the card and blowing air on the front and back of card. Am I thinking this through incorrectly? What do you guys think?

Right now I have a 860 Evo & a 860 Qvo both 1TB, looking forward to having one larger, faster SATA SSD.  I'll be splitting games between the new SATA SSD, and the 2TB M.2, based on how often I play them/if I enjoy them & how I judge their loading times/if there's a lot of loading times in the game.
So games like Dragon Age Inquisition & GTA V will definitely be on the M.2, not because I play them a lot, but because when I do play them I want snappy loading times & no hard drive laggos.  It's going to be interesting to watch the data migration fly when I'm transferring from my current game M.2 that's almost full to the new 2TB M.2, even in this system it should fly.  I'm going to try & transfer everything before the new CPU & motherboard are here so that it's a much smoother transition with the "new drives" already populated with the games & such, only thing that I won't be plugging in to this system before hand to do any kind of transfering is the 1TB M.2 that Windows will be going on on the new system - don't want this Windows messing that up, I've had issues with that in the past.
