Aorus 1080 ti copper backplate + evge hybrid watercooler

[Rothfox]

So i got this far fetched idea about something that i thought about the second i saw this cards cooper back plate.
Thinking of investing in a Evge hybrid cooler for some fun to see if i can lower thermals when using both the stock air cooler and strapping a Evge hybrid to the cooper back plate.
they should line up nicely if i'm not mistaking and the Aorus 1080 ti even has one extra unused pwm/fan header under the pcb where i marked (red circle).
does anyone want to see this done/tested, or does someone even have the 2 and want to do such a test for me?
Pictures for reference below:

i doubt that will be much of a difference if any at all

It may run a little cooler, but the cooling included is already pretty capable and will prevent it from thermal throttling. It wont really improve performance any.

Well... I would start by attaching a case fan onto the back plate right above the copper bit to see if it improves at all. As shown by video from youtube (cant remember who exactly did that video), it doesnt work at all in its stock config.

Possibly, still would be a fun test  the back plate is pretty hot to the touch, should dissipate Some heat from the card if the connection between them is good.

That's all i want to test does open headroom for Oc'ing with power limit modding.

Hmm, haven't seen that done. and i'm not really having throttle issues nor thermal issues. just a fun DIY project to see if i in an easy way can increase thermal performance to reduce both integrated fan speeds, temps and possibly get some better overclock out with the addition of power limit modding.  all just for good old OC fun

It may some, but that would depend on how good the chip is (Silicon lottery and all).

that it does! i do imagine 25-35hz to be possible tho   currently rock solid at 2050mhz core 5700mhz mem

You'd be far better served by water cooling the GPU itself instead of attempting to water cool the hot plate on the rear.

Invest in a Kraken G12... you'll get better results that way...

You wont get much higher out of the cards since NVIDIA locked the overvolting down (you cant do a custom bios with very high OC like you used to)... In today's standards, the cards are more limited by nvidia and silicon lottery than thermals and power limit...

what memory offset do u have?

if that was my intention i would indeed. i really just want to test if it would work drawing heat from the copper back plate

As i have said further up, thermal issues are non existent. purely doing this for fun and seeing if attaching one of those hybrid coolers is even possible and worth while in thermal gain
there is how ever 2 current mods to upper Power limit. you can update to the cards newest bios 125%-150% power limit. and you can "solder" the power limiters resistors by using liquid metal.

45+ (already highly factory clocked) core 600+ mem. All tho this is just synthetic since its not good to run 24/7, its still super solid and does not cause thermal problems.

The base clocks for memory already sits at 5616mhz when non oc'ed. but goes down to 5000mhz as power draws to the gpu chip. so really its just a power mod with 100mhz oc. so now that i think about it 24/7 should be fine. just higher electrickbill

Sounds good.  Have fun with that.

I did the shunt mod to my first two 1080 Ti cards.  Since my GPUs are mounted vertically in my case, I made some barriers to prevent any run off liquid metal from shorting anything else on the card.  I also coated the entire area of the PCB surrounding each shunt with liquid electrical tape.

 

The shunt mod does indeed work, but I wouldn't recommend it.  On my new 1080 Ti cards, I will be doing the capacitor mod instead.  Same concept, but much safer and more consistent then painting liquid metal in varying thickness onto the shunts. 

 

You can flash also flash the XOC (completely voltage and PL unlocked) or FTW3 (PL increased) BIOS in order to avoid the power limit.  I'm currently running the XOC and it works great for anything at 2100 MHz and lower.

Thx and i will!

Oh, nice! my card also sits vertical so that is indeed a nice touch i will be stealing.
i think i saw the capacitor mod, on a video. do you possibly have a link?

If you look really close just below the right shunt, you can see a drop of liquid metal sitting on the plastic protective barrier that I made.  Glad I trust nothing and went through the extra trouble.

So the capacitor mod is much more finite work, but it's much safer and looks completely stock.

 

All you have to do is place some 47 Ohm SMD resistors on top of the capacitors that I have circled in the pictures.  You secure the 47 Ohm resistor with a tiny amount of electrically conductive paint at the conductive contact ends only.  If you really want to do it nicely, you could use a small amount of non-conductive glue between the end of the capacitors and resistor, but that probably overkill as long as you don't go crazy with the conductive paint.  

 

Of course, if you are REALLY good with soldering, do that over using the paint as glue, but these capacitors are TINY.  You better be really good to solder that type of stuff. 

 

The resistors and conductive paint can be found on ebay.

i built my borhter a pc a year ago and recently - around 4 weeks ago- he got himself a asus gtx 1080 strix and i did a bit of overclocking yesterday with 2025mhz on the  core and +150 mem. I wanted to know if 76°C on a longer stress test run is bad since i made a quiet fan curve basically or is 76°C too unsafe?

76ºC is VERY safe. I personally consider anything over 80º to be hot, but nothing is really deemed "unsafe" unto you start getting into 90ºC territory, in which case the card will throttle itself.

76c is perfectly fine.

That copper plate doesn't do anything to effect thermals.

As some allready answered, its completely in the safe zone. personaly i could run the Aorus on 85%+ fan speed and not be bothered while gaming for 60*c ish temps. but it never passes 70'c oc'd on the costum curve i made so aint really a problem for me.

All tho you are completely right about it not doing much to lower thermals on its own.
In another way you "could" be wrong.
All back plates on gpus draw in some of the cards heat, and in this case it actually stores most of the back plates heat on the Copper plate, and back plate over the Mosfets and VRAM. 
so even if the copper plate does not directly decrees or effect thermals itself, it might do with a cooler stuck onto it. and as its a bare plate that is not connected directly onto something that can get fried, it should be safe to use liquid metal thermal compound between it and the AIO Hybrid mount.

Except it doesn't. Even if you provide direct cooling that chunk of metal does diddly squat.

Heh. Alliterations. And this made me laugh I dont know why. I've heard this phrase before. I must be tired
