This does not apply to 3090 users as 3090s already have backplate thermal pads and even a heat spreader on their rear memories. This applied more to 3080 and 3080 Ti users. When installing your Hybrid kit, you will hit a step where it asks you to place your thermal putty pads (they're made of thermal putty) back onto the cooler. Instead of doing this step here, you can take these thermal pads and apply them to the rear of your card where the memory is, like the 3090s. So reuse these pads on the rear of the card. I did some testing. My memory junction temperatures dropped from 100C to 88C. I used a temperature gun and the backplate in those areas is now at 40-45C while other areas of my backplate are at 28-30C. This means heat is definitely being conducted away from my memory modules. It's a free and doesn't cost you anything.

I saw an 8C reduction doing this with some Gelid pads I already had. Probably the amount of airflow over the backplate effects the result. I probably don't have a lot with the way my case is layed out.

I saw a 12C drop in junction temperatures, so it's definitely worth doing and it's free!

Was that your 3080ti or a different card? If 3080ti, what were you running to hit 100C?

This was my 3080 Ti card, and note this is junction temperature. The memory itself showed like 70C-80C. Junction temperature is usually 15-20C higher. I have my memory overclocked to +1250 so that might be the reason why.

I get about 80C max after running Kombustor for 10 to 15 minutes at +1100. 450w PL. It was 88C before I did the pads.

Try a RTX benchmark, it has been reported that RTX pushes the memory harder. My results are from looping and doing a port royal stress test. Kbird666 Sounds like something EVGA should be doing on Standard 3080 and 3080Ti's as SOP, like the 3090's. KB
Well 100C won't kill the card or throttle it yet. From a business standpoint, if I'm trying to maximize my profits, I wouldn't. But yes, from a customer standpoint, I wish they did.

I just converted my aircooled 3080ti to a hybrid yesterday and that cooled the GPU to a max of about 70C (whereas it previously maxed at 83C when aircooled). However, as a result, I encountered an increase in memory temps where it now peaks at 96C in RDR2 (whereas it previously maxed at around 86C when aircooled). Not sure how related this is, but I also encountered a ~20 FPS drop (90FPS to 70FPS) in RDR2 since converting with the hybrid kit. I'm guessing the higher memory temp is lowering the performance, even though those are supposed to throttle at 110C.. So before taking apart the hybrid cooler and redoing all the thermal paste and pads, I'm looking for a lower-risk alternative for cooling the memory as opposed to risking a redo of the whole thermal paste/pads completely. KingEngine, your advice sounds promising and also seem like a low risk of damaging the card. I have just one question before I give it a try. On the backside of the PCB, I can see the solder joints for the memory chips, however, there are a lot of resistors and caps ontop of those solder joints and they are not just unpopulated memory footprints. So I'm not sure if those resistors/caps are really a safe to place a thermal pad on directly.. Do you know if the backside of your board had resistors/caps directly ontop of the memory components where the thermal pads went, or if you think that is a relatively safe thing to do? I can send a picture if this doesn't make sense.

The thermal putty is non-conductive, you should be fine.

Just wondering but does the stock Hybrid 3080ti card have thermal paste/pads there? Does anyone know? I don't think I have seen a tear down of one.

I tried placing the stock pads on the backside of the PCB under the memory components (see below), but after installing the backplate, I noticed that there was still a gap between the backplate and the thermal pads (I couldn't get a clear picture of this gap from my phone). So I tried to roll up and play with the putty to make it thicker, but in that process it seemed to have dried up and would break off when I tried rearranging it. So instead, I placed some AIYUNNI 2mm pads that I had lying around: With these AIYUNNI pads and also after retightening the GPU screws, my memory junc. temps dropped about 4C (from 90C to 86C) on RDR2. However, these AIYUNNI pads aren't very moldable and they don't seem to have very good contact with the PCB-backplate, so I think my memory temps could still be improved with better or thicker thermal pads/putty. Since one of my stock pads dried out, do you know if there are any "orderable" thermal pads that you could recommend for this purpose?

2mm is not thick enough. Pads have to have mounting pressure applied to actually work. You have to have some compression. You should probably go with 3mm. I bet your pads are just barely touching. Sucks your putty was dried up, that's weird. Putty is different, it doesn't have to compress as much as pads to actually work.

Thanks, I'll order some Gelid GP Extreme 3mm pads off amazon and we'll see if that improves it (I'm guessing those are what talon951 used).

Somewhat related, I really appreciate KingEngineRevUp's various posts on the hybrid stuff. Between them and Dabadger84, converting a 3080 Ti went very smoothly and resulted in 20C-30C cooler temperatures across the board. Thanks for sharing your knowledge! Also, I ended up using the 3mm Gelid pads on the backside and it worked great.

Y'arr. That and dialing in the OC settings to work with the games I usually play. Always a fun surprise when you think youve got something stable and then suddenly: "NOPE."

Just added 3mm Gelid GP-Ultimate pads to the back of my XC3 3080 hybrid. Heaven benchmark got the hottest for me between it, the 3D mark benchmarks, and superposition so I used it to compare. 86C before the pads, 82C after. I was hoping for more of a difference and if say not worth the $30 at all.
The Gelid pads are fairly firm and the backplate is thin and flexible so there is likely very little compression happening. Might be better off using a softer pad, even if it's below the 15W/m-K of the Gelid pads.

Did you use Gelid Ultimates or Extremes? I got some Gelid Extremes 3mm on order and going to try installing them in a few days..

By the packaging - Extreme - Shore OO - 35 Ultimate - Shore OO - 60-70 The extreme should be softer. I was thinking the Ultimates were softer but I must have crossed them up. Might have mixed it up with the thermalrights too as they are 35-55 Shore C, which is harder then 60-70 OO.

I did the same as OP. But I replaced every stock thermal pad with the Thermalright Odyssey during the installation of the 3080ti ftw3 ultra hybrid kit a few weeks ago. Backplate 3mm is perfect for the memory. GPU Temp doesn't go over 70c (no undervolting, all at stock settings) and Memory temps don't go past 88c.

20-30c ? on GPU or memory ? whats your ambient ?

I'd guess adjusting your fans would make a pretty big difference. I think stock fan curve had my GPU temp in the 70C range. It's around 55C with different fan settings.

Am sure at that point in time, your PC would sound like a plane taking off. What does your fan curve look like ?

You would be wrong, my PC is VERY quiet.
I don't recall the exact values, but the stock curve let's it get pretty warm before ramping up the fan speed. If you just turn the fans on sooner, it keeps everything cooler, even at the same fan speed.
My suggestion, turn the fans on manually and find a fan percentage that meets your noise and temperature needs under heavy load. Then make a custom curve that jumps from zero to that percentage at like 35C, hold it flat until like 65C, then ramp it up to 100% at like 80C.
The fans will turn on immediately as the card sees a 3D load but sits at the same speed the entire time. IMO, fans varying speed are more noticable then fans sitting at a fixed speed, even if it's a higher speed.

03whitegsr You would be wrong, my PC is VERY quiet.
I don't recall the exact values, but the stock curve let's it get pretty warm before ramping up the fan speed. If you just turn the fans on sooner, it keeps everything cooler, even at the same fan speed.
My suggestion, turn the fans on manually and find a fan percentage that meets your noise and temperature needs under heavy load. Then make a custom curve that jumps from zero to that percentage at like 35C, hold it flat until like 65C, then ramp it up to 100% at like 80C.
The fans will turn on immediately as the card sees a 3D load but sits at the same speed the entire time. IMO, fans varying speed are more noticable then fans sitting at a fixed speed, even if it's a higher speed.
Thanks. Will try that out !
