fierceBeaver Posted February 17, 2018 Share Posted February 17, 2018 (edited) I found that modern heavy cards tend to bend down on standard ATX tower setups because of their increased over standard weight. I have ASUS Poseidon 1080Ti - it's very heavy card (waterblock + air heatsink) but it applies to any modern GPU if it's water-block or not. After some time it bends little loosing good contact with PCB/GPU. What you see on screenshot (GPU temperature on first screenshot) are temps fluctuation 42-57°C while moving right side of card little up. Of course it's a problem with GPUs installed horizontally. Remember air cooled cards are less efficient in cooling so you have to wait much longer to see temps drop after lifting the card. With waterblock it's almost instantaneous. Do NOT lift PCB - always lift heatsink/waterblock and be delicate. I lifted plastic with led next to power plugs. So Check it and look after it, It can be even 15-20°C of difference! Fly safe!:pilotfly: (Cooling is maxed for testing purposes and this max2228 was instantaneous benchmark crash after my curve mistake) EVEN BETTER: Edited February 18, 2018 by soundslikerust Link to comment Share on other sites More sharing options...
BitMaster Posted February 18, 2018 Share Posted February 18, 2018 I have 2 Poseidons, 980GTX and 1080Ti, and luckily do not suffer from this. Do I understand this correctly ? You assume that through bending due to gravity the cooler plate separates from the surface to be cooled ( GPU surface ) and thus the temp rises significantly ? If that is correct, I think the card hasnt been assembled correctly. Those cards are firm as a brick, heavy as a tank and the backplate looks very promising to me in terms of "I dont bend a mm". If you dare, take the card apart and make sure it had been correctly assembled. OR, do a RMA. Just did that myself, its gonna be a few weeks door-2-door.

I'm not assuming, i just proved it and made screenshot. when i started using a card it wasn't a problem but over time temps were worse. I started investigating my loop, radiator everything. And this was eyeopening discovery. When i meseured if my card is bended i noticeced it was. I noticed other cards bending like that so i wouldn't assume your's isn't suffering. I used a support, a plastic stick and temps dropped from 52-57° to 40's. and btw...WOW...yours overclocks like there is no tomorrow !!! 2088 ? is that stable, along with 12.5GHz on the Micron GDDR5x ?

D.Va Posted February 18, 2018 Share Posted February 18, 2018 This is extremely interesting. You should probably contact ASUS about it and whomever else it might concern, since it appears to be poor design.

You should probably contact ASUS about it and whomever else it might concern, since it appears to be poor design. It's not only ASUS. It's ATX standard fault. My last MSI gamers X 1070 had the same problem. When i uninstalled it after a 1,5 year use it was heavily bended. I didn't noticed it before i took it off the case.

BitMaster Posted September 12, 2019 Share Posted September 12, 2019 As of September 2019, supporting the card with a stick to prevent sagging is not enough anymore. My card's temp is 45-47°C in idle, it used to be 49°C in DCS, I got 65-67°C there now. According to a guy on ROG forum the springs that press the GPU cooler down onto the GPU itself are too soft and over time, this leads to a separation between the two, coupled with a thick thermal padding it has this bad effect at a certain age of the card. What helps is either mounting a full cover waterblock for 150-200€ for an Asus 1080ti-Strix ( same PCB )..or...put two washers onto the springs so they tighten up all the way and thus press the cooler firmly back onto the chip. I am doing the washer method asap and report back... next time,,,FE and after market block !

BlackLightning Posted September 19, 2019 Share Posted September 19, 2019 (edited) Thank you for having shared this. Do NOT lift PCB - always lift heatsink/waterblock and be delicate. I lifted plastic with led next to power plugs. I've googled gpu brace and I've noticed that many braces support the plastic of the heatsink. However, I've attached an image in which you can notice that my OEM graphics card was supported on the PCB. Maybe I'll do that the next time I open my PC to remove the dust (I'll do that more often than I used to with the old GPU, don't worry :) ) and I think I'll implement the following procedure: 1) place a bubble level onto a surface of the case which is reasonably supposed to be parallel to the GPU, 2) add shims under the PC until the bubble is centered, 3) carefully place the level onto the PCB of the GPU, 4) create a brace which makes the bubble centered and anyhow stop if I feel that too much force is being applied to the GPU.
