One of my gpus had a leakage I didn't know what it was, but suspected it was from the thermal compound. I had it running at < 60C at 65 TDP. It started to give me problems and eventually windows wouldn't detect it. I then sent it to the manufacturer and got a replacement. From experience, said leakage will lead to bad news. If your card is still under warranty I'd use it and RMA it, if not replace the thermal pads.

Problems that you had probably didn't come from thermal pads leaks in the first place it was just coincidence.
RMA at this state of market is just not advisable or may even be rejected if the cards is working normal.

The liquid won't do any damage to the gpu if that's what you are referring to and also there is no reason to change them unless there is high temp reading, all the liquid can do is gather dusts and look so ugly

I had a lot of this thermal pad leaking on my GPUs, and it's a normal thing with mining GPUs

I once asked the support of Galax, and they answered it's completely normal, this "liquid" is from thermal pad, and it's not bad for your GPU, there's no risk of failure because of this, but the downside is, it's ugly to see the card dirty, and will collect a lot of dust in certain points

You can clean with Isopropyl alcohol from time to time

There's some threads to research and learn more:

It's hard to get RMA, so better to clean the card and with the end of warranty you can open and change the thermal pads

Yes I have seen this also on 1080 ti cards. On the back of the card it had an oily residue. I wiped most of it off with a paper towel and then alcohol pads.

I would argue that the cards are running too hot. They should be clocked lower and be cooler.

I have plenty of cards with and with out the issue. It does show up on hot cards more easily than cool cards.

Ie 1080tis run for 3 years at 175 watts or less not stains or leaks

Same make and model run at 220 watts for 3 years have the leaks.

Yes, I think there's relation of how much the card is hot and the leaking of this oil
With all my only gaming GPUs, never had this issue, but my minig cards, all the hottest leaked

Started with my Galax 1080ti, with some RX 580, and most recently, my 5700 XT Gigabyte

I suspect the vram thermal pad is the most problematic, the temperature above 90°C running 24h/7 should be the cause of leaking

Happens on my windows builds more than my smos. The reason is simple my smos almost never do runaway max to the tdp random moves.

Windows builds do this more often and those cards get hotter.
I have been using smos for years and have found that this is often the case.

I think that manufacturers are trying to save on thermal pads or the supplier of thermal pads is trying to save money, so thermal pads release liquid when heated.
I have not changed my thermal pads, and when changing thermal paste, I wipe the liquid from the video card. This does not affect the operation of the video card

I'm doing some clean up on my rigs today and I notice some liquids coming from my gpus, like 5 of them like water stuff pour on them, but the cards are working fine but still that liquid doesn't look good at all, what could cause this?

This liquid appears when the thermal pads are heated, but it does not harm the video card.
I saw answers from video card manufacturers that this is not a defect.
Many miners recommend installing video cards horizontally or in another way so that this liquid does not get into the PCI-e connector,motherboard and power supply

BTW in cleaning your cards that has a bit of oily/grimy thing in it, better use a tooth brush-like that are thick (plastic) the kind you can find at hardware stores, it will more like throw/sprinkle the dirt away from the components, while thinner-real tooth brush will just squish the dirt around and an air blower can't do shit to grimy dirt.

no problem if you can't get the card squeaky clean from oil- that's not conductive, the black-grime-dirt is what you need to remove.

cards now have very small components unlike the old days but thick brushes can still clean it.

well thats was strange either capacitor leak or bad thermal pad which is most likely didnt happen, the bad thing is if the liquid going under pcb it will causing electronic faillure if the liquid really conductor or has lower ohms

It's the thermal pad on your gpu, sorry to say but the brand of the GPU use cheap thermal pad on your gpu that's why the cards are wetty, better order for thermal pad online just in case that on worn out because they never last anyways
