Definitely sounds worth doing, does it have be thermal pads? anyone experimented with thermal paste with heatsinks or liquid metal with heatsinks?

hits 108c mining @ 1100+

Per Customer support for the 3090 FTW3:

Hi Deadpocketss,

The thermal pad thicknesses are below in mm:

Cooler:
One pad 6.5*7.7*2.75
Two pads 14*53*2.25
One pad 12*15*2.25
One pad 5*110*2.25

Backplate:
One pad 14*10*2
Two pads 51*12*2
One pad 38*12*2

Regards,
EVGA

DZelmer- how are you keeping your junction that low??  Did I miss your setup?  The best I am getting is holding my junction to 96 and thats after a chunk of work.  My miner settings are similar- but my mem is at only +650 (t-rex).  The heat this machine is pouring into my house is going to make this unsustainable in June and July.
I am frustrated with my Junction temps- I would love to get in the 80s

a 3000 rpm noctua fan right on top and no back plate only .5 mm thermal pads...this was as temp set up but ya i just left it working on a solid copper back plate to put the mp5works cooler on. adding the hydro copper kit also. There should be some Pictures in one of these threads search my posts if that even possible.

Screen shots added to google drive Link above let me know it this doesn't work either

DZelmerMaybe this will work for me since i can't get any other way to work with out resizing the pictures down to almost nothing.
 
3090 Kingpin no back plate heatsinks .5 mm thermal pads 3000 rpm noctua fan about 2200 rpm

Yes can see the pictures, interesting way of cooling it. So looks like backplate itself is also not as good as direct contact with heatsinks.

 
I can see the pix on Google drive as well.
@DZelmer looks like you've got the gpu clock dialed down for mining. Are you using the card for gaming and/or work as well? What happens to the clocks, temps, etc, if so?
 
While we're waiting to see what Optimus brings to the table, I'm also working on a flat backplate for the back side of the card. I don't mine though, and the intent in my case of course is to bring those vram temps in check as well. I'm also not fond of the reported mediocre performance of the HC block, so I'm working on my own solution for that side as well which will include a generic gpu waterblock, a redesigned copper plate, copper shims on the vram packages, as well as tim and putty. It's tedious work, but for now I think it'll be the most optimal solution. 

How's this score? decent?

If you look at the same config as yours, you are good I believe

ya clocks are down for mining along with power to 75 if i turn them up it just runs hotter and pulls more power at the same 20-23 mhs. 300 to 320 watts seem to be the sweet spot for my card.  I can still use the computer for every say stuff running the way it is with out any problems. only time i turn the miners off are when im playing games just about every night for at least a hour when i can swing it. 
 
Not sure if the hc is just ok or the fact that these cards are quite power hungry and have to put all that heat in to 1 small area. Dabadgers temps seem to be pretty good with the hc kit. I have to get mine on also don't forget most of those reports are with out any back plate cooling at least the ones i looked at.

Yeah, to be honest, I'm still going to give the HC kit a chance, at least to record temps that I'll bump against the solution I described above. I'm down to no.4 in the queue for the block, so I'm hoping it won't be too much longer.
 
If the solution I described does blow away the HC kit, I'll probably order more front and back plates, then start putting similar kits up for sale. Such kits would include "universal" blocks for the front and rear, as well as everything needed to replicate my results (depending on watercooling setup), including very detailed instructions. 
 
OTOH, if I decide it ends up being a worthy effort (but), it will have been an interesting experience. FYI/FWIW, I've got the equipment here to do flow and pressure drop testing as well.

I got the 3998 1k bios last night from Vince:P
It let's me use classified but I still need to confirm that it actually sets voltages to card tonight 😅
Also I think I have an old version of classified or at the very least not the latest

Great! looking forward to you're results.

Will do.
 

wow that's cool

Can someone who has latest classified check the properties of it and see which version it is?

Don't forget to reset the dipswitches before you roll on the classified front.
 
The version I have is 3.1.4.0
