Aluminum Heatsink on the back of RTX 3090

[TIG]

I found several videos on Youtube showing that Aluminum heatsink might improve about 5 deg the VRAM temperature. Any thoughts ....?!!!

Everything helps. Heatsink + better airflow, heatsink + peltier elements, waterblock.

Saw people who used bykski ram blocks on back because they are cheap. I used myself a block from mp5works + heatpipe.

Would you mind post a YouTube video, so I can take a looks at it?

Jamebonds, check this link. Be careful, do not open your GPU. Just do it from outside.

personally im not testing fate overclocking,ive heard some RMAs are being refunded
while i like the idea of cooling it more.i see no need for overclocking my 3090.@ 1440
anyway.but i may look into those heatsinks.

Yeah, most cards will benefit from it, if you make proper connection with thermal pads and heatsinks.

It's been done for years, it will continue to be done for years.
There are some types of cards that run heatpipes over the back of VRAM too, so it can better spread the heat out over the backplate.

Not practical for something like VRAM - It would use to much power, produce no temperature difference, require some form of management to avoid condensation/dewing/freezing in the event it did work.
It's not worth it for VRAM. For CPUs, or even the GPU itself, then sure, I could see some form of usability, even then it's a stretch.

The best way to use Peltier coolers is put them in-line on a loop, so they cool the water, instead of the CPU itself, that way you keep the liquid extremely cool, but not cool enough to freeze, or cause condensation on the pipes. And would be away from any parts, like CPU or GPU, in the event it stops working, so your computer doesn't just overheat.

I saw some pics on reddit. He used 3 peltier elemets with low watt and heatsinks on top. It was enough to keep it vram on 40°C. Peltier elemets are usless on 300w cpu or 500++ w gpu but it looks like on a backplate which reaches 90°C it works fine.

Copper works better.

Thanks all for your good interaction here. Yes, I 100% agree not to OC any GPU that might reduce the life-time of any gpu.

The suggested heatsink solution “aluminum or copper” just to keep the VRAM away from reaching over 90 deg. GPU demanding games “like Breakpoint or Control” bring the VRAM as high as 85 deg in my case.

I have Asus Rog Strix RTX 3090 and i9, 9900K, 32GB RAM cpu. I just want to keep my GPU safe as much as I can especially for the current worldwide GPUs shortage.

I know, it is only 5 deg temperature reduction but seems good and cheap solution for such GPU.

are rigs are pretty much identical i have a EVGA 3090 TW3 ULTRA and a asus 501 case though
the sweet spot seems to be 85% fan speed on the GPU makes a pretty big difference in
temps. dont know how the fan noise is on the asus but its minimal on mine.

In general, my Asus GPU is so quiet even at high fan speed. I have no issue at all with the GPU temperature. For Asus Rog Strix 3090 temperature never exceeded 75 at super and ultra 4K settings for any game. Again the issue with VRAM that can touch some time 85 deg. That is my worry.

Beware of C°/W (thermal resistance). If it is too high, then it will overheat the GPU. If it is too low, then it will make some IC working slower. I have seen them before, they are from Digikey.com.

Bottom line, if you do add these aluminium heatsink, I would recommend to compare with GPU stress program before and after added an aluminium heatsink.

Sorry, that makes no sense, adding cooling to the vram on the back of the card cannot overwork or overheat the gpu due, it's only beneficial.

Unless your overclocking and mining so full load for example, there's no need to worry about the temps.

The one you want to look for is gpu memory junction temperature on hwinfo64, as long as its sub 110c you are fine, at that point it can begin to throttle, but if you don't want to mess attaching heatsinks etc, you could just point a spare 120mm fan at the back plate and drop 5-15c depending how fast it is.

Agree with you. This is what I will do before and after applying the heatsink solution by monitoring the heat performance with GPU-Z software.

have you seen maicrosofts new water cooling?

pretty neat
