It just works like a dream it really honestly does

Pump failure a little over a month after purchase with light use. Returns/warrants process is very inconvenient. PC will be down over a week with advanced return option. Recommend going with another cooler.

The mounting hardware was very wonky and did not seat well into the pump block. I ended up returning this product due to the poor temperatures associated with a poor mount as well as a very loud pump. Wish they had just stuck with asetek pumps, but this is a coolit pump.

It is flashing red, giving me a water pump error. Temps are fine, no cooling problems, but still flashs red. The internet is showing that this is a common issue.

The pump on these Cappelix units can't be set lower than 2300 RPM, mine was loud and had an annoying buzzing sound. The fan control unit can only control one type of fans (WPM or DC) and only takes proprietary rgb connections, so it's difficult to add your own fans to it.

Thoroughly disappointed. Design seems nice, and fans seem to be a major upgrade from the previous ones. But the pump noise is problematic. Much louder than my previous corsair AIO. Pump noise is an audible hum which happens to be louder than my pc fans. I can understand my fans being audible but not the pump, not when it's set to silent. Looked it up and apparently it's a normal occurrence. A decent amount of videos on it with the same audible hum. Not going to bother rma'ing it since it's not indicative of pump failure, just poor design.

Very efficient. A little loud but that’s to be expected.

Good product but the pump died on the second day after installing. Installed another one I just picked up and it worked fine so I know my new PC wasn't the issue.

I have seen many builds with this product installed but I was not lucky to get a great piece for my build. The fans had a rattling sound and the pump was too loud. Saying that the product is great if you get a good one.

the pump is too loud and has this annoying whine. temps are ok. i would look at other options unless you really need iCue integration

I bought 2 of these. First one was dysfunctional. Happens often with this cpu cooler. I returned it and got another one and that one worked fine. If it only blinks red lights return it.

Broke in a year. The pump died and I had to buy a new one.

- Failed after 3 months of usage and now getting shutdowns because the CPU is overheating. Pretty sure the controller failed because it doesn't show up in iCue and the RGB lights no longer turn on. - Requires a controller that runs the pump. The only way to power/control the pump is with that box and their bloated software. - The controller only handles 4 pin fans that adjust their speed via PWM. 3 pin fans will run at full speed.

Fans on this radiator are "meh",... bought some Noctua NF-A12x25 which are hands down far superior. Also some of the fins came damage from the manufacturer

This has been a waste of my time. It is a lot of work to install and remover etc. Keeps things cool but has a discernable whine. Ran at extreme as Corsair suggests. Will try tilting machine 45 degrees as suggested. Returned one already as I thought it was a one off but this is just not acceptable.

Pros: -Great brand -Nice design -Easy installation -Much RGB Cons: -Loud pump and fans stuck at 2200+ rpm regardless of "Quiet" settings

it just stopped working on 4/2022. After I took it out the cpu block smells like a burnt unit.

Bought this for my new build in a Phanteks P400a case and when mounting it hoses down (as it should be) in the front of the case the hoses are way too short. They will barely allow the pump block to reach to reach the processor on my Z490 motherboard and would not allow the GPU to be mounted at all because the outstretched hoses were in the way. I wish the hoses were 3 to 4 inches longer and it might have worked great.

Had to use a Cooler master instead and it worked perfectly fine .

Didnt do much for my PC, Came damaged but now i cant return it because my gf threw the box away. It brought my temps down may 5-8 degrees from a 140 mm. The colors dont work because of the broken RGB hub or fans? Im not sure. I do know its wired correctly. A piece snapped off one of the connecters which was already hanging by a thread when i got it and causes for a bad connection.
