Hi,
I saw this post https://www.reddit.com/r/EVGA/comments/ozi5hr/fix_for_30803080ti3090_hybrid_memory_and_vrm_temps/ and I put some kapton directly on my gpu backplate.
It works but obviously not as effective as directly applying to pcb.
Is applying Kapton tape to the PCB dangerous?
I'm worried the area around the RGB light bar could get damaged https://www.techpowerup.com/review/evga-geforce-rtx-3080-ftw3-ultra/images/back.jpg
The cutout on top of the gpu seems fine to cover right?
Not sure where to post this
Thanks

    What are you attempting to accomplish by using Kapton tape? I am very confused.

    Edit: Sorry, I didn't mean to be condescending when asking that question. I guess I just don't understand Reddit... still. I tried reading the link but got confused about what you were referring to versus all the other random unrelated content Reddit throws at visitors.

    It's preventing the air from going through the card and forcing it to go out the back through the IO shield.

    Makes sense. In the XC3, there is actually VERY little area for air to go around the pump in the cover. There probably is actually more area going through the card then around the pump...

    Another option might be too cover the back of the backplate and around the edges but leave the edge at the back of the card by the IO shield open. This would still allow some air through the card but still likely increase the air going across the front of the card. The potential extra benefit being it also forces air across the back of the PCB to help cool the PCB as well.

    That is brilliant, and so obvious.

    Yeah I dont get all these bastardizing Cards I have seen here over the last few months....yes backplates get hot...thats what theyre supposed to do, dissipate heat.
     
    If thats the purpose of the tape (thermal reduction ..no idea)...not really sure, I gave up on air cooling a GPU many years ago ;)

    The air flow through the shroud does in fact help cool the vram, as it flows over the back of the AIO memory plate and PCB, if you turn up the shroud fan on a constant load vram temps drop.  OP is talking about taping up holes on the backplate where air flow is lost out the back, he linked to a post where someone put cardboard in there.  This will definitely work and I'm kicking myself for not thinking of it months ago.

    Makes sense then, especially if its been trialed and proven.....I do recall back when I had my SLi / Tri SLi 580's, prior to finally moving to water....I had all kinds of fans and stuff going on trying to keep things cooler....the Northbridge on those Evga X58 Classified Boards were a challenge, throw 3 GTX 580's on the Board and you could heat a house while benching ;)

    Meh...

    Covered the back plate and sealed the sides of the backplate leaving only the IO edge uncovered.

    Ran 5 minutes of Heaven as a warm up, then 10 more minutes while logging GPU-Z. Average memory temp was 0.5 degrees higher. Peak was the same.

    I'd say it did nothing or made things marginally worse.

    I do have thermal pads on the back of the VRAM and I essentially insulated the backplate from air going across it. Maybe I'll try blocking off just the PCB holes, as originally posted.

    Covering a heatsink = insulation = higher temps
     
    Limiting airflow .. not the best idea ....... just have a fan blow directly on the backplate = better cooling for benchmark runs

    exactly
     
    I'm also in no rush to see what is on reddit .... OP should put the info in their post

    Thats exactly how I cooled my(infamously) hot Northbridge on my Evga X58 Classified Board.....fan blowing right onto it...not pretty but it helped.

    Yeah, I had edited it and forgot to save it stating about the same. I have to wonder if that extra fan you speak of would actually be better used on the front of the card, forcing air into the shroud/fan.

    If you're already conducting heat to the backplate, I find you results to be expected.  I'd try just blocking the pass through vents opposite the fan.

    Hi,
    https://imgur.com/gallery/H2c2Sbo
    So I put Kapton tape on the pcb cutouts so the airflow goes out the back of the gpu.
     
     
    After some testing with mining the memory reaches 86c with all fans at 100%.
     
    That is GPU Hybrid Fan, Push Pull P12 fans & a X2 GP-12 fan on the back of the gpu.
     
    So it hasn't really made much of a change from having the tape on the backplate.
     
    I can feel a lot of air coming out of the gpu where the LED connector is, so that is probably the next place to block outbound airflow.
     
    Thanks

    If you are going to do this mod, it seems that plugging those holes with wide strips of thermal pads would be way more effective. Tape can loosen up, the edge can flap around, it doesn't seal well around complex shapes, etcetera. A thermal pad would be wedged in place, wouldn't go anywhere, would seal better, would conform to complex shapes, and would at least conduct some heat from the PCB around the edges.

    I did a quick and dirty test of this with a port royal stress test with the blow-through covered and uncovered.  Zero difference.
     
    Top mem temp was 72 covered, 73 uncovered
    Top Memory junction temp, 90 covered, 90 uncovered.
     
    I do have 2 140mm intake fans on the bottom of my case blowing right on the GPU and controlled by the GPU temps, so that might be why I am not seeing any difference?

    Not expensive. Cheaper than a roll of kapton tape. Way better than kapton tape.

    I've got three rolls of kapton doing nothing and where are you buying the stuff that it's more than $10 for a roll?

    Hey man, do whatever you want. I'm just saying a thermal pad is a better long-term solution. Where are you buying stuff that a generic large thermal pad is expensive?

    Those temp reductions in the reddit post seem exaggerated.

    If you are going to do this mod, it seems that plugging those holes with wide strips of thermal pads would be way more effective. Tape can loosen up, the edge can flap around, it doesn't seal well around complex shapes, etcetera. A thermal pad would be wedged in place, wouldn't go anywhere, would seal better, would conform to complex shapes, and would at least conduct some heat from the PCB around the edges.



    Sounds expensive and a bad idea.

    Not expensive. Cheaper than a roll of kapton tape. Way better than kapton tape.



    I've got three rolls of kapton doing nothing and where are you buying the stuff that it's more than $10 for a roll?

    Hey man, do whatever you want. I'm just saying a thermal pad is a better long-term solution. Where are you buying stuff that a generic large thermal pad is expensive?



    You mean like a generic silicone insulating pad?  Or a thermally conductive pad?

    I am not able to replicate it.  Hardly any air goes through those holes even with the blower fan at 100%.

    Why are you even in this thread with your condescending BS?  You don't even own one of these card so why do you care?

    I am just trying to offer some assistance. I'm not the one arguing that $10 worth of thermal pads is an outrageous expense. Why you need to find me and argue with me is beyond me.
