Alphacool NexXxoS XT45 Full Copper 420mm Radiator (14170) | All-Copper Fins, Channels, and Chambers, Three Fitting Positions per Inlet and Outlet, Flat Chambers for Tight Spaces

Great built Awesome quality beast! All copper, came super clean (for a copper radiator), packaged perfect, performs as expected, or better! Reason for buying this - I previously had an XSPC 280mm but thinner height wise, and it was also great, but I also have a 380mm Radiator, 2 1080ti GPUs and had my CPU in the loop but temp it's not. All that stuffed in a mid tower got to be a bit tricky and decided a crossflow radiator would help me with draining and hard tubing routing. I thought this one was also a crossflow but it just had a port on the other side in addition to the 6 ports on the one side! This was perfect as the routing no longer an issue and drainage is drasticly improved! Pros - Everything , and it's full copper, this thing holds and with a bit of static air on it the heat just dissapates quick like! The tapped g¹/⁴ " opposite from connection end with stopper is perfect for front or vertical mounting to add a drain valve as draining these vertical is tricky without this! Cons - almost nothing, it's copper, again, it's very soft yet durable just make sure you have it ready to mount where and when it won't be as likely to have to keep moving it around just to avoid unwanted scuffing or scratches. The fin density didn't look very dense but it's also 45mm thick so you don't need monsters behind and or in front of them but you don't want a super cheap case fan either. Some 1500 rpm 140mm x2 Noctula fans work for me and are quiet, not really a con but more of a side note. This beast was pricey but works and looks great do far! If debating between this and a 360mm even if it's somewhat thinner and you have the room for a 360, I would go with a 360, but if cooling say one GPU or one CPU Overclocked or one of each and still OC it can handle it, but a 240 usually is more fit friendly, all depends on your setup. Would and may buy another one without hesitation!

Very good and very clean. I didn't have to flush this one but I probably should have anyways. Love the thickness and the 3 different inlet/outlet to choose from and a drain. It came with outstanding mounting hardware and 5 very nice looking metal stops plugs. Even comes with extra screws for replacement. For this price they could have given less but I feel they went above with all that included hardware. Like it's enough to mount it 2X so that's absolutely cool and give it more life.

Thick and juicy. 4 inlets and an additional drain. Make sure your case can fit 560mm radiators!

I do a sink test on every rad I buy now, some of the cheapo china versions leak like open hoses so I learned a valuable lesson there. This one is far and above those in quality. Solid copper, fins are perfect, great threading on all the inlets and first flush came out totally clean. Zero leaks under pressure testing, my only beef is the angle of the black spray leaves the fins looking rather raspy from its off angle where the paint got zero coverage for those like myself that are uber picky. This is going in a small form factor build so no one will ever see it.

The radiator has some serious heft to it. The fins weren't bent or marred and they include a package of screws and plugs to help you mount fans and your radiator to your case. In terms of price, you can tell you are not getting shorted in terms of materials. This is a pretty dense fin stack and I think it's worth the money. The additional 120mm fan section from your typical 360mm rad means you can run your fans at a lower RPM and get the same performance with less noise. I do have one minor gripe about it. There are 7 ports (3 on the inlet and outlet and one at the top, probably for bleeding the air out of the system or as a fill port), but they only give you 5 of the G1/4 screw plugs. So you either have to go buy 2 more or hope that those flimsy little plug plastic plugs don't come out and spill water everywhere. How does that make any sense?

I've bought 3 of these so obviously they work well. The problem and reason for the 3-star rating is all three are warped. That is the face is not flat. The first one was so bad I had to send it back and they sent me another twisted one. Fortunately, it wasn't as bad and I managed to get it to work with a thick foam gasket. I just recently bought another one and it is also twisted about 1.5 - 2 mm out of flatness. I can make it work but it's never going to be right and honestly, I don't want to wait for another one to get sent as it took a week to get here, and other brands won't work in the space I need it to work in. I'm disappointed that no one checked these before sending them out especially after getting returns. With all that complaining aside, nice radiator. It has 6 ports on the bottom/top and a single port on the opposite end, very versatile and all copper. Just be sure to clean it out well before use. I poured boiling distilled water into mine and shook it before draining, repeat 3 times.

No leaks. Accurately sized too. So what else do you need? I have this and a 280mm version in series with two water blocks cooling an i7-14700K and RTX3070. With 520 Watts going into the water I get under 10C rise in water temperature at the entry to the radiators. Room temperature was about 21C, at idle the temperature was showing 25C. The fans are controlled by the GPU and motherboard, so fan speed increases when the core temperatures rise. At maximum load the GPU was at 47C and the hottest CPU core reached 85C. With a good quality 360mm AIO I was getting 100C on some cores.

PROS - Multiport - Thinner form factor - Non restrictive CONS - A bit lackluster thermal performance - Price - Better options but fits niche builds Alphacool has been a decent brand for a bit now within the world of water cooling. This rad is decent but at its price point there are other brands that provide better performance, it shows it's age. I primarily purchased this to fill out space in my phanteks enthoo 719, due to a few factors. I usually stick with hardware labs, but unfortunately the form factor of the nemesis 360 gts was I think 5 mm to wide to fit on the bottom of the case. So after a bit of scouring and and comparison I went with the xt45 version of the nexXxos, the 45 denotes the thickness. It sports 6 ports including a drain port on the opposite end which made it excellent for use at the bottom of my loop. The rad is not very restrictive in terms of flow rate, which is great due to me running 2 nemesis 480 gts and a top mounted 360gts which are quite restrictive. This is also just under 5 inches in width making it fit perfectly into my case. Thermal wise this sits in the middle of the pack in terms of performance but considering the price at time of purchase it's not particularly good for the dollar. Alphacool rads ( at least in the past) I have found to be quite dirty with alot of remaining flux etc from manufacturing still present so flush the rad accordingly.

フルカッパーで正しく使えば安定して冷えますよ。

Well worth it cools my system down drastically overall temps went s from 45'C to 30'C when combined with my other radiator. Now I need some free fans Amazon. Lol....

ケースリアへ直に取り付けようとすると、リベット止めが当たって取付できませんでした ミリネジのスペーサー(ケースとマザーボード間の六角のやつ)を付けるか、間にファンを挟むかしないといけない様です ラジエーター本体のフィンピッチは広めに取ってあってgood

Lo sto provando in questi giorni. Non mi dispiace. È molto spesso (45mm), ma ha poca densità di alette. Ne consegue che non serve metterlo in push/pull, ma bastano due buone ventole da un solo lato per garantire un buon flusso d’aria. Comprato solo perché avevo parecchio spazio vuoto tra top e scheda madre da riempire, e un 30mm in push/pull non ci stava per un pelo. Come resa pare come qualsiasi altro 280mm (stessa marca) da 30mm avendo questi utili una densità di alette maggiore. 25-7-22 messo in push/pull cambia la musica completamente. Rimane piuttosto silenzioso vista la bassa densità di alette, ma adesso si sente chiaramente il calore che viene scambiato/spinto fuori dal radiatore anche a bassi regimi. Sempre più soddisfatto. Per raffreddare un [email protected] ed una rx 6900 xt (gaming gigabyte) ho dovuto aggiungere un 360x30 ed un 360x40. Con 30 gradi in casa, nei giochi più spinti, cpu 60 gradi max, gpu 70 gradi max, liquido 40 gradi max. Tutte le ventole al massimo, non è più silenzioso per nulla. Non vedo l’ora torni l’inverno :-)
