Yeah, both cards seem work very well until now. Greatly appreciated for your kind comments and suggestions!

Hi, @c-attack, I've replaced the themal grease with a new one, for both the GTX 1080 Ti FE (card 0) and the Hydro-GFX-GTX-1080 Ti GPU (card 1). Now the cooling for card 1 seems imporved. Please check the following two pictures: where the first is at its idle time and the second is at its busy time. The cooling for card 1 has significant improvement (~70C at busy), while the cooling system for card 0 has no clear improvement (~88C at busy). Now we can confirm that the liquid cooling from the Hydro-GFX (card 1) is still OK and has positive abilitiy. Not sure why the cooling for card 0 has no improvement. I think maybe it is because of the themal grease. I used the https://www.amazon.com/ARCTIC-MX-4-Compound-Micro-particles-Durability/dp/B0795DP124. I bought the themal grease three years ago when I bought the CPU box. Now I used this themal grease into the GPU card. Not sure if this is valid for the GPU card. The following are some pictures when I replaced the thermal grease for them. Please check the attachments.

Hi, I've opened the GPU card and it seems like the follows: It seems the thermal grease became solid. So I plan to replace with a new thermal grease. Hope this can help. With regard to the liquid cooling system, it seems we can surely replace with a new liquid cooling or air cooling system. grease

Hi, thanks a lot for your kind comment and suggestion! If the card is completely not working, I plan to remove the liquid cooling part. Currently the air-cooling system still works.

Yeah, the CPU AIO cooler in my PC is working very well, but the graphics card described before seems broken. I found the warranty policy in the official website: https://help.corsair.com/hc/en-us/articles/360033067832-Corsair-Limited-Warranty, which says "All graphic cards have a 2-year warranty". So my card might not have their service.

Hi, thanks a lot for your kind comments and suggestions! Yeah, I also thought this card was probably broken in the cooling system. In fact, I also bought a CORSAIR Hydro Series H100i v2 AIO Liquid CPU Cooler for the CPU cooling, this cooler is working fine. If things are as you kindly pointed out, it would be great that we can replace the liquid cooling system with other new liquid cooling system. But have a look at the card, it seems the liquid cooling part is fixed into the card and as a regular user, I'm not sure how to take it down and replace it. The card is used for three years, so I think the Support Center might ignore my request.

Hi Dear Sir/Madam, I bought a Hydro-GFX-GTX-1080 Ti GPU card (https://www.corsair.com/uk/en/hydro-gfx-1080-ti) from this official website three years ago. This card has been running quite fluently in these years. Now, things have changed, where I think the main cause is the breakdown of the liquid cooling system for this card. When running with full load, the GPU temperature will be nearly 90C and the GPU Fan speed will be 99%, which produces a huge amount of noise. Please have a look at the following picture: where the GPU 1 is the card what I said. The GPU 0 is a GTX 1080 ti bought in the NVIDIA official site (the founder version). At the first one or two years, the card 1 is very cooler than the card 0. For example, the card 1 was always about 50C~70C, while the card 0 was about 60~80C. But starting from the last year, the card 1 seemed be broken and the gpu fan was very loud and I worried about that whether the card 1 was really broken. But it seemed to be able to run with high temperature and high fan speed. Could you please give some advice on how to fix this issue for this card? I thought the main cause might lie in the liquid system. Is there any way to change the liquid in the system? How could I achieve this? Is it possible to change the liquid with water? Thanks in advice!
