I suggest not getting a CLC but an AIO like Swiftech H series, be quiet! Silent Loop series or Fractal Design Kelvin series, not that I said before. The Kelvin is copper radiator and made by Alphacool. I don't know who make Celcius for Fractal Design, but it hasaluminum radiator.
Ignore posts by peeps who doesn't seem to have a clue as to what AIO and CLC actually are .. just like most buyers out there don't know the differences.
There are all kinds of people out there who make statements with no knowledge to back them up, even some supposed experts. Good example is UK Gaming Computers article about open loop versus closed loop.
The real definition of open loop and closed loop are;
Open Loop = a liquid loop with that is not a sealed loop, one that is open to the air at it's highest point to keep liquid from leaking out.
Closed Loop = a liquid loop that is sealed with a plug or factory sealed so the liquid cannot leak out of it.
The above is definition that has been around for more years than AIO, LCLC, CLC etc. But now we have CLC with many thinking it's means 'closed loop' and a custom loop somehow is an 'open loop' .. when the reality is both are closed loop cooling systems with LCLC / CLC being factory sealed with no way to add coolant or change components. I use the term CLC because it is what everyone is familiar with, even though it is incorrect.
Here is link to another writeup about CLCs that author also differentiates between AIO and CLC

At the end of the day the real issue is 'water cooling' with a custom loop is a totally different and much higher tech cooling system then these cheap CLCs that cost the same or less than just a good pump with no reservoir or fittings cost .. Custom loop pumps all flow many times more coolant than CLCs do.
CLC mass sales are based on the idea that 'water cooling' is the key point. But their advertising glosses over things like pump flow rate and head .. so much so it is almost impossible to find any data showing the flow rate and heat of Asetek pumps or any of the other CLC pumps. They know their product is not much good and depend on advertising hype to suckker buyers in. They are more Carnie Barkers than anything else .. an the ill-informed flock into buy the because they say it's 'water cooling'.
If we stop and think for a minute here, how do you think a £80-100 CLC performance and longevity compares to the £500-1000 worth of components used in a good custom loop? Sure, there is probably a lot of markup in the components so price is probably much higher than it needs to be, but the pricing of CLCs is also artificially higher than need be.
I don't know if you remember, but when Corsair first came out with their H100 there were literally hundreds and hundreds of problems .. so many that for well over a year we had factory refurbished H100 cooler selling for about half their new price .. but with 90 day warranty until the government forced them to give a longer warranty. While not as many problems, we have seen similar releases where there were all lots of problems with 1st and sometimes 2nd and even 3rd release of these before they managed to get them working well enough to last a couple of years.
I advise not buying any product that does not have several reviews by credible review sites .. and also keep in mind review sites rarely talk down a product, because they depend on companies giving them samples to do their testing on, and then they usually sell on those samples to make a little money for the time they spend doing the review. If they put down a product the company will most likely not give them any more samples .. and no samples means they won't have anything to review .. so the obvious solution is to not put down a product in their reviews.
