Great budget CPU AIO cooler.
Bought this for my recent PC build... I wanted to replace the stock AMD Wraith air cooler with something a little better. It took a few minutes to fix as the pipes were trying to go above my RGB ram and I wanted it to run below... but I got it to fit in the end and it looks great. The RGB can be controlled with the included controller,, but I had a MSI Mystic Light motherboard so connected it directly to that instead. Looks lovely with the rest of my build. It is a little noisy at times but im ok with that as long as it gives good cooling performance, which it does!

Works well and really quite once you sync up your fan tuning software.
Worked really well for me. I did get some fan noise when I 1st installed it but once I ran my fan tuning software (fan expert 4) the fan noise went away. CPU temp reduced so much the high rpm was not required. On high load my CPU was running at 83°C with my old tower air cooler but since installing this it not reached any higher than 65°C. Can not even hear the pump (thought is wasn't working at 1st) fans come with very handy splitter. Fans have minimal nose but easily changeable to perhaps more silent fans. Oh and all works well with. My aura sync set up.

Good quality product but fiddly fitting instructions.
I got this cooler for an absolute bargain price, so no complaints on that front. As I was fitting this to an already built PC I found it was slightly fiddly to get the radiator and all the cables routed. I can only imagine it would be easier doing it from scratch. The radiator I received had some squashed fins, but nothing that will seriously hamper performance or make me want to return the product. Overall the pump and radiator are of a good quality and everything looks nice once installed. I would recommend watching an online video to help with install as the fitting instructions provided are not great, and if you are inexperienced with such things you could have problems. As a cooling solution, the cooler works really well so far. I had a Cooler Master 212 rgb and swapped it out for this, and I've noticed a drop in temps of about 5c on my overclocked Ryzen 5 3600 (unscientifically recorded!) The fans for this cooler are not the quietest, and I can definitely hear them where I couldn't hear the 212 air cooler I had fitted before. This doesn't bother me if I'm honest. When my PC is idle I can't really hear the fans and when I'm playing a game I'm usually concentrating on the game so don't notice any increase in volume from the fans. I would recommend this product overall, but there is a lot of cable management, and the fans supplied are only 'ok'. Edit: having had the cooler installed for a few months now, I can honestly say that the performance of the AIO is very good, but the fans are of a poor quality. They started off with an acceptable level of noise, but have now developed an intermittent rattle that must be based on fan speed. I will be replacing both RGB fans with Noctua ones at the first opportunity and relegating one of the RGB fans to a case exhaust.

Excellent cooler
Not a great deal to say about this cooler, other than if you are new to putting together you're own PC, then watch videos on how to do it, as the instructions are not very clear. It assumes you already have knowledge of the motherboard and various pins you need to connect to. Also, if like me you have a Ryzen chip, you have to make sure you have the correct bracket to install this onto, as it does not come with the AM4 chip bracket. Performance wise, it dropped my CPU from around 60 to just over 30!

Epic way to spice up your rig
Great RGB lighting with high a quality feel throughout it. It's a fairly quiet piece of kit that does a good job at cooling and is surprisingly easy to install. It is very good quality for a relatively low, budget liquid cooler.

Not recommended
This appears to be a nice cheap 240mm AIO. It does cooling things. I bought it ages ago for a failed project and didn't use it for nearly a year. I've had some issues with my PC and I had to remove it from the CPU. While cleaning off the old Thermal paste I've noticed that the cold plate that contacts the CPU is incredibly rough - it's a Satin copper finish. Most coolers have a very smooth cold plate to provide the maximum contact area, which the thermal paste improves. This is why I've had to rate it a 3 start and recommend that you spend a similar amount on a high performance air cooler or dig in your pocket and buy a better AIO.

well worth the money :)
ok I like this cooler simple to set up but only downside is fans bit loud but seem to be quieting down a bit after first week :)

Great for the price
pretty good bit of kit, installation is time consuming but ultimately easy as the wires are pretty much all predestined to only fit one hole. You'll need your mobo manual to get the correct ports but frankly if you don't know that you really shouldn't be trying this. Be aware that whilst theoretically compatible with Asus aura, I couldn't get it to work the built in software package is perfectly good though. Excellent for the price.

Mooie maar luidruchtige oplossing
Altijd gegaan voor grote luchtkoelers. Lekker stil maar nu met een R9 5900x toch maar gegaan voor water koeling. Kleurtjes zijn super en maar waarom die twee grote fans niet wat rustiger hun werk kunnen doen. Geen idee!. Zo hard draaien ze niet, een soort onbalans maakt het erger. Kan met de bios profielen ook geen oplossing vinden die het oplossen.

Ottimo dissipatore a liquido
Avevo già avuto modo di provare un dissipatore a liquido, ma questo è 10 volte meglio. Dentro la scatola si trova il grande radiatore collegato alla pompa RGB, 2 ventole trasparenti RGB e il controller RGB. Dopo 2 anni di utilizzo ancora è perfetto, le temperature sono basse per un I7-8700k sia in gaming che altri programmi. Le ventole sono silenziose è molto belle da vedere. Per quanto riguarda L installazione è stata abbastanza semplice non ho spanato nessun foro del radiatore, mentre il controller qualche minuto L ho perso per capire come si collegava. Positivo: - design RGB - radiatore 240mm - ventole RGB - silenzioso - già in utilizzo da 2 anni Negativo: - nessuno Se posso essere stato utile lasciate un voto grazie.

CoolerMaster Tip - Top
Habe schon den kleineren Wasserkühler mit einem Lüfter gehabt. Bin von CoolerMaster begeistert. Pumpe und Lüfter laufen ruhig.RGB Beleuchtung ist einfach top. Der nächst Größere mit 3Lüftern kommt bestimmt.

Gute und efektive Wasser-Pumpe
Bin sehr zufrieden mit Coolermaster Master Liquid ML240R. Pumpe läuft mit vollem Drehzahl(2400 )ruhig und leise. 2 Lüfter am Radiator laufen mit 850 Drehungen. Die mitgelieferte Lüfter habe ich mit Coolermaster MasterFan 120 Halo getauscht. MB : Asus Rog Strix B-550 I -Gaming miniITX PROC. : AMD Ryzen 7 5700G mit Grafik RAM :Corsair Vengeance RGB Pro SL 2 x 16 Gb GEHÄUSE :Metallicgear Neo MiniITX V2. Alles läuft wie am Schnürchen! Temp. Idle - 22-25° C 4k Videos - ca. 30° C Sieh mal die 2 Bilder am ext. klein Monitor,geklebt am Glasscheibe. Einziges zum Meckern gibt,daß die Schläucher ein wennig zu kurz sind für seitige Einbau. Top Einbau genau passend. Ich konnte die Pumpe für 180° drehen,ich wollte aber so wie möglich die Schläucher nich sichtbar zu werden. Auch Luftkühlung ist dadurch effenzienter. RAM Speicher sind nicht wärmer von 35°, was optimale Arbieitsbedienung ist. Fazit: Sehr guter Preis-Leistung Wasserkühler,welch nur empfehlenswert für Top - Einbau ist.
