[SOLVED] GPU backplate gets too hot

[yesyesloud]

LMAO. You really don't get it. Why antagonize members and by extension other members who value their contributions, just because you don't like their response or advice to your request for help?

You simply had to not take my advice, but you decided to make it personal, even knowing nothing about me. Quite frankly, this is a small, POLITE community for the most part, attitudes frowned on. Please try and remember that, sir.

Good luck to you in your PC endeavors, and I do look forward to our interactions on TPU again in the future, since it's a relatively small community. Maybe you'll be able to help me!

sure, explaining why I didn't get your advice in detail is very, say, parsonel

I love how warm and doubtlessly full of good intentions some people have been on this thread, even on my inbox.

I certainly started all this mockery... Pardon me.

Luv ya guys

when i was playin FC4 my vrm temps were high(as i thought)
ghetto mod helped me, i just put 2x120mm fans between videocard and CPU cooler pushing air to top, it helped - from 89°C to 81°C
also, how long do you use your 7990?mb change TI?

As much as I hate backplates I kinda understand their usage in cards like yours.

I wouldn't worry about the temp of the backplate as long as the rest of the temps are decent. But, since some heat will dissipate from the PCB to the Backplate, if you manage to lower the temps a bit you may shave a couple ºC.

On the offtopic, next time someone suggests something that you THINK/KNOW won't work, skip it, or say thanks and move along, as in the end you will do whatever you seem better for your particular scenario.

Can I reply if I wish? I assume so.

If you take your time to read the thread comprehensively, you'll notice I only answer somewhat ironically to those who also imply some sort of ironic tone.

Thanks for your wise advice not already implied by other users, but evidently I worry about steady 100ºc+ under the board.

irony and sarcasm are both allowed on the forum.


all you can do is directly cool the backplate by sticking a fan on it, or indirectly cool it by improving your case airflow.

VRM and core temps read by gpu-z are good. Only backplate-covered vrms are probably high in that department.

Yes, we are all people, at least I think so... Let us learn to take jokes back instead of only throwing them at the others, so that the forums get more fun

Edit: sorry, I forgot to mention the card is reeeally away from the tiny end of my H100i cpu cooler (that won't go higher than 50°C).

Thanks for clarifying all that. Hadn't got to that conclusion yet.

PS: nah, case airflow has nothing to do with this situation

 

[st2000]

VRM and core temps read by gpu-z are good. Only blackplate ones are probably high.

you got 6 chips of vrm from one side and 6 from another
what do you think is making you backplate so hot?
from cooler side there is some air flow, but from back..

case airflow has everything to do with it. you need direct cooling to get it off the heatplate, then indirect cooling to vent that heat out of the case. If either of those is insufficient, you end up in the situation you're in.

Nope. Airflow is not the problem at all here. Please read the thread.

lol, I know what is making my backplate so hot. 113ºc+ at the moment. That's why I'm worried.

In case its thermal design isn't clever enough, that plate is not really doing a good job on its cooling role.
And I replaced quite a few stock cooling solutions in the past for they were horrible.

Thanks for the tip anyway.

 

[st2000]

also. i'd buy vrm heatsinks, thermalpads and replace backplate with this(not sure if it can help, but i'll try)
also directional cooling as close as possible to backplate/back side of card to remove hot air is a good idea
right now i advice to downscale memory clocks and set low in amd overdrive power consumption
backplate is good idea from engineer thought(what is heatsink - just a piece of metal with high square)
but using backplate without any active cooling/heatpipe connected to main active cooling system is just imperfection

 

[Daemmon]

It actually is doing it's job. Backplate can be 120ºC and nothing will be harmed, specially since you say that your case airflow is good, which means the heat leak to the mobo shouldn't be big.

The PCB gets cooled from the fans on the other side, but some heat is passively transfered to the backplate, and the backplate has no way to dissipate the heat other than... well passively.

Is it smart? No, that's why I don't like backplates. Specially the ones that has some extra space between PCB/Backplate. That makes a small oven in between the two that is actually bad for temps.

Just throw a effing steak on top of it and call it a day.

 

[st2000]

there is even the worse thing: vrm chips WITHOUT any heatsinks and active cooling

 

[Toothless]

Airflow is the isssuuuueeee~

Quit being an annoying know-it-all elitist that disregards everyone who has the correct theory.

That's the easy path

I'll cool the backplate for the fun of it. Or just fry stakes.

It's the most controversial bit on vrm-covering backplates though (when they're not designed to be actively cooled).

If a dense piece of metal is fed heat continuously, chances are it will start to heat the source back either to a point it becomes useless. No one can actually solve that puzzle without reading those mysterious vrm temps for a good while.

There's a guy on another site saying his backplate was actually raising temperatures from extensive measurements.

Airflow is the isssuuuueeee~

Airflow, yes. With proper sinks stuck on the backplate, for actual cooling sake.

Case airflow, nope. Not at all. Sorrah.

Quit being actually-the-fish-in-my-mouth-that-can't-take-disregard-back.

Well, case closed. It will be sinks on the plate or leave the plate alone.

 

[st2000]

they're not designed to be actively cooled

in most cases backplate is installed only for supporting long cards/not to damage the card

Oh, didn't know that, thanks. This backplate also has thermal pads on vrms though:

[st2000]

just dont know what to say to be more polite/kind(i'm not angry or trying to be angry)
what solutions you replaced?in which PC?what if you tharmalpads on backplate are absolutely dry(cause it's not so obviously to understand from all previous thred)

Just to confuse the matter, caught this tonight:

image: http://imagescdn.tweaktown.com/news/4/3/43953_02_closest-look-nvidia-geforce-gtx-titan-here.jpg

The Titan X has had its backplate removed, which I'm sure is because the GM200 GPU powering the Titan X and its 12GB of VRAM runs much hotter than the GTX 980. The GTX 980's backplate gets ridiculously hot as it is, so I think this is a great move by NVIDIA and something that needed to be done in order to keep the card from getting too hot.

I don't really think that what makes the backplate hot is VRAM, I can assure you that after hours of benching on absurd voltages and insane memory frequencies I could touch my GPUs VRAM even when benching and they were warm at best. (Talking about my current GPUs now)

From my experience what made hot my 6990 backplates was the INSANE heat the two chips close to eachother were outputting.

I'm pretty sure it's the voltage regulation circuitry that radiates most of the heat to the backplate.

 

[DinaAngel]

it could help to buy lots of those small copper heat sinks and use thermoglue and make the whole backplate covered in those heatsinks. But it might look iffy if your very into making it look tidy or nice

Ghetto mod and pics please.

Which i said back @ post 13, but apparently this guy knows better about a problem he is asking help for lol.

How ever i suggested a 120x12mm as it depends on the CPU cooler if a standard 120x25mm fan would fit even more so with a back plate.

Ignorance is bliss

best solution if you got huge cpu cooler and little clearance between videocard and cpu cooler

Worry not, I got your good vibrations from the very beginning, like from many others... I'm not even remotely trying to be angry either (?). Only had great fun and a couple of insights for plate cooling on this thread.

I replaced my old, not backplated 7970 stock cooling set with Icy Vision Rev.A and countless legacy nvidia cards' with custom mods for a school project (meaning the cards went for some schools, not me).


Thermal pads on the 7990 backplate are fine, otherwise it wouldn't get untouchably hot. There have long been conclusions on what's the best cooling solution for my specific scenario, but fun never ends in this thread.

I'll stick sinks on the backplate (or on vrams directly if I'm brave) and then the extra fans will be finally worth it.

Or else I'll leave it be the way god planned it, just like wisdom teeth.

I don't really think that what makes the backplate hot is VRAM, I can assure you that after hours of benching on absurd voltages and insane memory frequencies I could touch my GPUs VRAM even when benching and they were warm at best. (Talking about my current GPUs now)

From my experience what made hot my 6990 backplates was the INSANE heat the two chips close to eachother were outputting.

I'm pretty sure it's the voltage regulation circuitry that radiates most of the heat to the backplate.

Let's suppose the big source of warmth is the pcb itself not vrams... My 7990 backplate has been 100ºc+ most of the time and its thermal pads (designed for thermal conduction) touch back vrams exclusively. As it features no decent cooling design, then this plate definitely transfers great, unnecessary heat to those vrams.


My core temperatures are pretty good, usually below 70ºc when both cores were long in use - they always share the work, I have crossfire profiles for all of my games. Only when running a single core it will go higher than 75ºc on demanding titles, but I don't roll that way. Vrm1 and vrm2 are fine too.

Anyway, I haven't measured temperatures on the board reverse vrams directly yet. I suppose they're the main heat source because backplate thermal conductivity pads only touch them; otherwise that backplate is pretty useless as pointed out above.

Talking about Nvidia Titans, it seems the upcoming one has gone plateless

it could help to buy lots of those small copper heat sinks and use thermoglue and make the whole backplate covered in those heatsinks. But it might look iffy if your very into making it look tidy or nice

Thanks, that's what I'm going to do. I'm proud of my Frankenstein.

If you read the thread, you would realize I got the desired solution from other users' suggestions. Ignorance is *iss indeed.

Also, you'd realize I enjoy when people focus on the actual problem instead of rambling on long, repeatedly addressed side questions

 

[Daemmon]

Vrm1 and vrm2 are fine too

Sorry if you posted them somewhere but I couldn't find them. What's the average temp on the VRM1/2 on load?

 

[yesyesloud]

It's ok. I didn't post them as those vrms are properly cooled. After an hour through Crysis 3, they keep on the 75-80ºc mark and cores at ~70ºc.
