r/buildapc on Reddit: Am I supposed to drain/refill my water coolant for my Corsair Water Cooled CPU pump?
April 28, 2023 -
My CPU temps have been higher than normal recently. I am evaluating all my options and am curious if my cooler needs new liquid.
I looked it up and there are tutorials and whatnot when it comes to draining and replacing the liquid. My Corsair (forget exact model) water cooler is just mainly a fan and radiator that connects two pumps to a metal plate for the CPU.
I have not messed with it since I got it (3 or so years ago). I purchased some water coolant from Corsair on Amazon to refill it. However, is this a mistake? Am I just spending money on something uselsess/scam?

Lots of misleading answers here. AIO coolers have a 3-5 year lifespan so it could definitely be your AIO even though they are closed loops they are still prone to evaporation, that’s what limits their lifespan topping them up extends their lifespan. Note I said top up not drain/refill. Some AIOs (BeQuiet for example) make this easy by supplying extra coolant and providing a access point to fill top them up. Others are trickier, usually requiring removing the crimp where a hose attaches to the radiator and then pulling the hose. For this reason most people just replace the AIO.

Corsair H100i refill? | [H]ard|Forum
August 29, 2020 - I would just get a new cooler instead of trying to refill it if it really has lost that much liquid. ... If you do go the new cooler route, I'd suggest looking at the Alphacool Eisbaer series. They're uglier (imo) than the Corsair units, but offer one big advantage: being able to take out, refill, switch out components as needed.

r/buildapc on Reddit: Can we replace the liquid in a aio?
October 25, 2023 -
im getting my first PC built and my friend is building it for me. This is his first time installing an aio and I got a Corsair iCUE H100i RGB Elite Liquid CPU Cooler and when he was trying to install the new bracket he thought u needed to unscrew the copper plate to get the brackets off so he did. And some of the liquid came out not much though. I closed it back. But is there a way to refill that liquid that came out?
Update: thanks everyone for the help. After reading everything Im just going to get a new aio and have someone else put it.

Just an FYI, if your friend did that on an AM4 and he's building the computer for you, you may not want him to build it for you.

I'm confused as to how the liquid came out of a sealed cooler.... It depends on how much fluid was lost and if that impacts performance. The only way to know for sure is to run it. If it's running fine, then there is nothing to fix which is not ideal to do anyways. I would use distilled water if you do, IIRC Corsair uses a mix of glycol water and inhibitors.
