$h!t Manufacturers Say Ep. 1 - "Backplates Cool Your Video Card"

This video is not up to date anymore. The RTX 3080 severely throttles due to memory overheat if you have no thermal pad to make contact between the backplate and the back of the PCB where the memory chips are, even though the chips are actually in the front of the card. GDDR6X runs crazy hot (~100°C). It’s a common issue in Gigabyte 3080s, and other manufacturer’s models, though in mainly affects people who do numerical computing/mining. I had my 3080 Vision gain up to 20% performance after adding thermal pads to the backplate (and no, removing the backplate altogether does not help, so it does genuinely provide cooling).

You forgot to test the card without the copper backplate.

I have a R 9295 X2 and I have some chip (memories) cooled by my backplate whith termal pads. So on some cards the backplate is not only here for have a nice look. (Sorry if my english is bad I'am french and I don't use Google translate).

I know this is an old video... but the backplate on my 3090 contacts the vram on the backside of the PCB. The plate itself sits at 70c while mining and it's too hot to touch right where the vram contacts it on the underside. I had to attach heatsinks to the plate and add fans to wick that heat off my vram.

nowadays all gpus have a backplate

The bite-sized quarter coincidingly trot because birthday oddly attempt forenenst a tasty half-sister. dashing, plant criminal

It's flir not flur

Open test beds are kinda bs for testing thermals.

i ran into a voltage limit, said no ambient pascal overclocker ever, you ran into a thermal limit unless you were sub 45c

what about that vram temps

With the 3000 series's gddr6x it actually does help

what about memory junction temp? what about fan speed? poor vid, congrats

Now they do lol

if it doesnt cool something then why is it burning hot when i touch it

whatever happened to this guy at ltt?

I'm from 2021 and Linus just release video about water cooling backplate rtx 3090 and they actually work

THIS HAS AGED LIKE MILK

A revisit would be appreciated.

The copper backplate looked like the copper plate in a cpu water block. Probably a terrible idea, but what about water cooling the copper backplate?

3090: hold my RAM

Me blast the first part of the video my mum thats sitting right next to me

3090: laughs

Well this aged really fucking poorly

I miss when luke made videos

lol HAHAHAHAHAH this aged well

lol they need that in 2021

Laughs in 3090 water block

it does help with memory on the back on the card to cool the memory with the rtx 3090 or 3080

What about VRM temps?

It's now 2022, and this aged so awfully

Well this video didnt age well lol.

30 series is on the block now

RTX3090 has entered the chat.

Maybe in a case with more airflow than a testbench it would perform better with tha backplate

Hei linus for now EKWB making water blok cooling for back GPU KEKW

This guy was incredibly annoying to listen to. He was annoyed because of the, excessive, little screws? BTW if heat is being dissipated and removed via passive air, then its working. Maybe not immediately, or reducing core temp; however, it certainly helps keep it from building core temperature.

Same power consumption? No thermal throttling? Same frequencies and voltages etc? Same fan speeds? Any chance the thermal paste you used was better when you rebuilt it? Any chance there's significant case fans blowing air across the back of the card?

Could be that the back plate is as much a net insulator due to poor thermal contact/interface conductivity, as it is a heatsink? Theoretically more cooling surface area = cooler temps. Could we use thermal paste instead of/as well as a pad to help?

The 3 degrees it was reducing, it was adding back on with the built in led!

GDDR6X: Well, Well, Well, How the turntables...

you need to push it to the limit in order to see if the head sink helps. if the normal operating temperature is 67 C, there is no where to significantly reduce it. if you push it to 100C, you need to disperse the heat and test if this copper plate does that

Even when this video came out it was wrong I achieved superposition world record (for a titan X maxwell) by adding a back plate

I feel like this should be looked into more these days.

Think it's time to revist it this. 2024 gang

Its crazy they still want $400 for this card 😀

67% yea but the fan speed are diff with n without the backplate

gtx 1080











holy shit , it has been a while huh

Came here from a WAN show mentioning this series in December 2024. It would be amusing to revisit this one with the labs setup and to compare with newer graphics cards just to really drive the nail in the coffin.
