Hello.

I have a h220x from swifttech sitting on my 4790k. the cooling performance has gotten extremely bad over the past 2 years. it reaches nearly 99 degrees while stresstesting on stock clocks and voltages.

I've noticed green/blueish chips and residue in the reservoire. this to me looks like copper rust.

Could it be that there is so much rust build up that the cooling performanace hassen gotten so bad?
The h220x is a customisable closed loop so can i take it apart and clean it?

Any help would be appreciated since i have no experience with watercooling.

Thanks in advance.

Im not familiar with this model, but my guess is that its a AIO cooling unit, if so then it technically doesn't need maintenance and the coolant inside shouldnt cause any erosion to the point of leaving particles inside the reservoir. If theres 'chips' a small pieces inside it could be coming from the block, wich could explain the bad temps.

Also, is the pump functioning properly?

You can generally remove the base plate (the plate on the CPU) and clean it all out.
I did something similar with my Corsair H100i.
You can get yourself some coolant as well to retop it up.
The problem when corroding happens, it could mean there is a leak somewhere and air is getting into it. I don't know your system and how much liquid there should be, but you can drain it all out into a bowl and then flush the system with clean water.

I sorted everything out then my problem was the pump was bad :(
But it was my first time disassembling an AIO and I had no problems what so ever. I used a baking tray to catch the water and screws I put in a small cup. It was a lot simpler than I thought it would be. I amazed myself :)

Any kind of particles in your loop is going to cause the flow through the CPU block to get inhibited, meaning less and less coolant is taking that heat away. You should absolutely clean it if possible. I'd get some reputable coolant, and I'd check the whole thing for leaks prior to putting it back in.

I'm going to see if i still have the stock cooler for it. and then take the h220x apart, might aswell try since it is of no real use to me now.

I see, so maybe there could be a little hole in the top of the rad from which air is coming in....

You could blow down one tube and block the other one up, and see if the pressure is disappearing.
Also like you said, add your original cooler since this one is obviously defect in some way, once you get that repaired/fix all will be good!

As for your band language... All I can see you said was "also should i flush it with vinegar or something?" Maybe he thought "flush_it" was it or was a joke no one got...
