    Voila des annes que je cherchait a faire un watercoling custom,
    j’ai pris le temps de la rflexion regard tuto sur tuto ,
    pour arriv sur ce kit qui n’est pas forcement le moins chre de base ,
    mais qui apporte un suivit pice et option plus confortable sur le long terme.

    je suis tomb avec le temps sur la chaine de JayzTwoCents qui a mont se quitte le mettant en avant pour ceux qui dbute dans le watercoling custom, et aprs mure rflexion j’ai opt pour se kit plutt que du Termaltek ou autre beaucoup plus abordable.

    la photo parle d’elle mme j’ai opt pour le nouveau boitier 011 Dynamic evo avec une carte graphique mont en verticale. ce qui ma permit plus de fantaisie dans le tubing.

    le gain en temprature n’est plus a mtre en avant ce qui ressort le plus c’est le silence obtenue si on a une config gourmande qui ventile beaucoup.

    mon conseil regard bien toute vido sur le sujet prenez le temps de savoir pourquoi vous voulez franchir le cape.

    le kit Corsair n’est pas mon premier choix , mais celui qui rpondais le mieux a mes aptitude et attende dans se projet.

    Merci corsai

    Absolutely add life to my build, beautiful addon to a gaming desktop, might not be a faint of heart for the extra effort or the extra money for everyone, nor does everyone like RGB, but definitely add a new level of aesthetically pleasing comparing to good old Air cool or even AIO in my perspective.

    This kit came with everything I needed and even had extra hard tubes for mistakes etc. Very well packaged and each part comes with instructions. Only downside and why I’m not giving 5-Stars is the rusted radiator like some other people received as well. Not sure why these are rusted or why Corsair isn’t doing a proper QA with the radiator but overall this kit was 4-Stars.

    Sehr einfache Montage und es ist bis auf die Heiluftpistole alles dabei. Temperatur nicht zu hei einstellen und gengend Abstand halten. Ich empfehle jedoch eine Gehrungsschneidlade mit Sge (s. Bild, ca. 10 Euro), da bei mir die Enden allesamt schrg wurden mit dem Corsair-Set. Ein Rohrschneider hat bei mir nicht funktioniert (PMMA bricht dabei). War auf Anhieb alles dicht. Khlleistung 12-15 C besser als mit dem H100i pro und sieht 1000x besser aus. Die Anleitung von Corsair ist kurz, es gibt jedoch unzhlige Videos dazu auf den bekannten Plattformen. Ich kann es nur empfehlen! Und der Einbau macht sogar Spa!

    Solide Kühlleistung- einfacher Einbau, auch für Einsteige

    This is my personal recommendation for this water cooling kit, which is very convenient for beginners to install. If there is a 240 cold row version, it can be used when assembling the itx case.

    Golden Review Award: 8 From Our UsersI’ve seen a few posts concerned about the radiators. This is completely normal. It’s not rust copper does not oxidize THIS IS NOT RUST copper has little to no iron its called patina and its a layer formed on copper from moisture and is almost impossible to stop its 100 percent safe to use and does not flake off. Cheers! Have fun with this sweet kit!!

    The first hard line cooling install.

    The kit includes everything you need to build your own bespoke hard line cooling system, except the heat gun.

    Great cooler but may need to replace the thermal paste

    Kostet bisschen was aber tut was es soll, sogar besser als erwartet.
    Ich empfehle jedem gleich ein geeignetes Kugelventil und G1/4″ Doppelnippel mit Aussengewinde zuzukaufen um in Zukunft die Flssigkeit einfacher auslassen zu knnen.
    Messing und Alu nicht mischen!

    Expensive for only lower my temps by 2c, with no overclock or excessive load on my rig. Max temp reduction I could achieve was about 6 c running pump and fans at 100%. System is fully bled, but still underwhelming cooling performance from a 360 rad.

    El kit viene completo, tiene todo lo necesario para la instalacin. Lo difcil es que no te indica como integrar el commander con el hub y demas componentes, por lo que para usuarios sin experiencia puede llegar a ser dificil, tendrn que investigar mas.

    Es bastante divertido ensamblar el enfriamiento, pero NOTA, se requiere pistola de aire caliente, li vas a comprar este kit considera que puedes gastar otros 50 dlares en la pistola.

    En cuanto a la calidad del producto, es muy buena, con buenos materiales y acabados.

    Los contras: el precio de mas de 500 dlares, faltan las gomas de los ventiladores para evitar vibraciones.

    En general si lo recomiendo si tiene el dinero para comprarlo, mantiene el cpu super frio

    It was first time for me to set up a custom loop and it was harder than I thought.
    The acrylic tubes are very tedious to work with, but the finished look of right angle and cut is just so pleasing.
    Ps: I had to buy 6 more 14mm tube..

    Hard but pleasing

    First time installing water cooling. Kit has everything for install of a single cpu, and rad. Had to purchase additional rad and fittings to install additional 360 mm and 140 mm rad. If video card doesn’t come with a water block,, you will need one as well. Pump has no problems with the added rads. Make sure that if this is your first time installing water cooling, buy more tubing as I did and don’t be upset if you mess up one or two tubes. Cones with the leading process. Make sure to water test before adding power to motherboard. System runs under full load (benchmark test 1 hour+) 65 – 70 C on junction with overclocked cpu (ryzen 9 5950 4.5 ghz) and over clocked gpu (Radeon rx 6900 xt)

    Apatentemente Por el momento no me a dado ninguna falla, por el momento todo marcha bien y espero q asi siga , el producto es muy bueno y vaya que enfria mi procesador que es un ryzen 3900x de 12 nucleos , tenia el enfriamiento ryugin asus y la temperatura estaba entre los 35 a los 42 grados y con este enfriamiento de corsair la temperatura se mantiene entre los 25 y 30 grados ,super frio el procesador , muy recomendable(si quieren q la temperatura baje mas hagan que el agua circule en tubos mas largos para q el agua fria se mantenga mas tiempo corriendo y la caliente se enfrie con mas rapidez )

    Great kit, went from 50 degrees to around 30 degrees Celsius at the CPU.

    Only 2 things I disliked.

    1: When filling your reservoir with coolant… take the tip of the filler off. It fell off in my reservoir and took me longer to get it out than to fit the pipe.

    2: I tried every way (I used to install pipe on submarines) to cut the pipe, it would either break or cut slanted.. best way I’ve found is with an air/electric grinder with a cutting wheel.

    Just the tip.

    Golden Review Award: 8 From Our UsersThis was my first PC build and my philosophy was go big or go home! I originally was just going to replace my GPU, and picked up a RTX 3090, but things quickly snowballed from there. What was meant to be a simple GPU switch out, turned into completely redoing my rig except for my motherboard and PCU. Since I got a new case and new RGB RAM I decided that I would try doing hardline PC cooling. The Corsair Hydro X system along with a generous amount of YouTube and here are the results! I only comment is, if you are considering this make sure you plan it out well and make sure you have enough fittings to accomplish the loop you want. Long story short, this is a great product and pretty easy to install.

    C’tait mon premier water cooling custom et le kit est super complet et d’excellente qualit, prvoir simplement d’acheter un set de tubes en plus si c’est votre premire fois car on gche beaucoup avant d’arriver la bonne forme.
    Au niveau bruit la pompe est inaudible, les ventilos sont efficaces et silencieux
    Le RGB est splendide (bon courage avec le cable management…)
    En temprature j’ai perdu 20 en idle et 28 en charge sur Ryzen 5800X (je suis pass sur mtal liquide au passage – conductonaut)
    Un conseil, prenez le temps de regarder un maximum de tutos sur YouTube avant de vous lancer…

    Golden Review Award: 2 From Our UsersSo this kit was VERY well thought out. I built it into a Thermaltake Tower 900 as I really like the design of the case. Very easy to understand the couplers that join the hard tube with the elbows/connectors. The reasons I gave it a 4 star are:
    1. I ended up having to order 4, 90 degree elbows to make this work. This kit didn’t come with a you block and without those short runs, it expects to have 3-4 bends in a single pipe which makes it extremely hard to get every bend perfect. I feel that for a $600 kit, they should have included at LEAST a pair of 90 degree tube to tube connectors.
    2. The res has two wires for LED that come out of the top. You can’t remove them and it looks ugly without gluing them to the side of the res tower for a clean install.
    3. Pump/res combo has only one port where you can have it exit. It would be super awesome to be able to have more than one out port where you can block off one for a super clean install. Or be able to rotate the top of the res cap so that the input and output can go to the rear.

    Other than that, it looks super cool, doesn’t leak, rob fans are incredibly quiet and keeps my 5900X under control.

    Their marketing doesn’t really help you identify the correct additional parts. Everything is named HydroX series… make sure to look at the outer diameter of the piping. I got a 14mm and ended up waiting a few more days to get the correct elbows. Not exactly stupid proof for beginners.

    Want to see them come up with a couple of water blocks for the different 3070 gpus and I’ll buy another set of tubes, rad, fans, pump etc for the other side to have two separate loops.

    Golden Review Award: 2 From Our UsersI love this custom water loop kit, it was my first attempt at a custom loop which was difficult so the loop don’t look like I planned, Before I was getting temps of 80+ air cooled playing Cold War in 4k max settings and now with the hx303i I’m in the mid 50s
    I ordered more tubing I got the hang of bending so I’m going to attempt to run the loop as originally planned
    The pump is not too noisy
    I definitely recommend

    Looks beautiful stays cool

    Golden Review Award: 3 From Our UsersIt is the best watercooler ever. It soooo silent that I barely notice it was on. It makes my Ryzen 9 5950x stays in 42C, what is unbelivable. It’s RGB combines with my GeForce RTX 3090 FTW3 Ultra. It was hard to find, there’s none in Brazil, s I had to change my region to USA and pay almost 700 dollars in taxes, but this product worth the price. Recommend to everyone. You won’t regreat buying it.

    Golden Review Award: 3 From Our UsersAlso wie soll ich es sagen. Es ist meine aller erste Custom Wasserkhlung und hatte echt probleme beim Biegen der Hard Tube’s. Aber nach dem ich alle 6 verballert habe hat es funktioniert. Naja zwar nicht so schn wie ich es mir vorgestellt habe aber immer hin. Die Khleistung ist auch drastig gesunken. Hatte vorher die ASUS ROG Ryujin 360 Aio mit Fligmetall gekhlt. Im IDL lag es bei 33C und in games ber 60C. Mit der Corsair ganz anders. Normale Wrmeleitpaste liegt die IDL bei 28C und in games nicht mal 55C. Gekhlt wird ein Ryzen 9 3900x auf 4,1Ghz all core. Bei Prime 95 lag die Temp bei etwa 60C (laufzeit zirka 1 stunde) Spter wird noch meine 2080ti mit der Wak und ein zustzlichen radi verbunden. Denke mal aber das ich auf Softtube’s umsteige muss man net so krampfhaft biegen. Deshalb ein Stern abzug wegen dem biegen. Ok die Qualitt ist echt lcherlich vom Video

    Das Set ist auf jeden Fall praktisch da ist alles dabei,die Sge und die Rohrbefestigung zum Sgen ist nach paar Rohre Sgen schon unbrauchbar. Wasserpumpe war bei mir nach Inbetriebnahme undicht, aber der Rest hat gepasst. Nach erneuten abdichten der Pumpe ging es dann und die Pumpe ist sehr still. Auf jeden Fall empfehlenswert.

    Bought this kit for my first custom loop and wow I’m amazed at how easy it was to put this all together and once you get the hang of bending the tubes its a lot of fun just remember to buy a heatgun as this does not come with one!

    Golden Review Award: 3 From Our UsersIt is one great product if you know what you are doing, and what to expect.
    If you want to do a custom loop just for CPU and have an expectation of the custom loop thermally being better than AIO, No it will not. if you plan to have a custom loop for CPU and GPU at the same time, you will have an amazing experience. The pump and CPU block is very sturdy and well built. the pump has up to 4500rmp and it is dead quite up to 3000 rpm which is more than enough for daily use.

    Amazing combo

    For a first time builder of a custom water loop I have to say I’m pretty pleased with this kit. It comes with nearly everything you need to build your loop. I say nearly everything because it doesn’t come with a heat gun to bend the tubes; but a $20 Wagner will take care of that. Bending the tubes is a mix of art, science and patience. I really like the way my setup turned out and would definitely recommend this to someone looking to get into custom water cooling.

    Golden Review Award: 3 From Our UsersDer Einbau war wirklich gut. Man bekommt wirklich alles was man bentigt. Das war meine erste WaK und die Tubes haben trotz mancher Fehlversuche gereicht, habe jetzt noch eine Stange ber.
    Das einzige Problem ist die Befllflasche, Corsair WTF?? Vorne am Schlauch die “Dse”, so nenne ich es jetzt mal, ist nur auf den Schlauch gesteckt. Wollte nach dem 2. befllen den Schlauch herausziehen und was passiert? Die Dse fllt ab und landet im Ausgleichsbehlter, Weltklasse! Fisch das Teil aus der kleinen ffnung oben erstmal wieder raus, da bekommste richtig Spa sag ich euch! Nach einer Operation mit Pinzette und Garn (damit die Pinzette nicht auch noch da drinnen landet) habe ich es dann wieder heraus bekommen – Glck gehabt..
    Sonst wie gesagt, alles in allem ein Rund um Sorglos Paket.

    Befüllflasche Katastrophe, sonst sehr gutes Gesamtpake
