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.

Yes, this AIO is a "Closed Loop" liquid cooler and comes with the coolant internally. The liquid coolant it contains is a type similar to the fluid in your cars radiator. By the way, you don't have to fill or refill these coolers ever since a closed loop cooler and should never leak.
