NexXxos XT45 Full Copper X-Flow Radiator, 420mm, Triple Fan, Black | Full Copper Construction, X-Flow Design for High Flow Rates, 45mm Thickness, Three Fitting Installation Possibilities

Hands down the best customer support I’ve seen in many years from ModMyMods. Radiator had a QC issue from AlphaCool was offered a replacement immediately but chose to fix it myself with full support from ModMyMods. Ended up not fitting my case due to advertised dimensions being wrong (Fault of AlphaCools website). Spoke with seller they offered a different model as a replacement no questions asked. Most sellers would not have done this as it’s the customer’s responsibility to ensure product fitment not theirs. Communication was also top notch, professional, quick response, knowledgeable associate with many suggestions. Overall extremely satisfied with the purchase they went above and beyond to help make it work and will be using ModMyMods exclusively in the future for all other purchases. Thanks again!!!!

GPU temps min 26c max 51c 3080TI CPU temps min 32c max 59c AMD 5950x Rads are a little hard to see in pic but one on top one on bottom 30mm on top 45mm on bottom Have been using Alphacool rads for 12+ years now always recommend by me for water cooling builds crossflow are really the way to go if you want to cut down on tubing runs and increase flow rate

I wasn't expecting this thing to cool as well as it does, it's as if I've got two 360s in this one 240 radiator. Because this thing is so thick. It's a little bit weird fitting things, but if you've got a big enough case, I suggest this thing immensely. There are quite a lot of different ways to set inputs and outputs, so it's modular. As far as fitting into a case, they at least figured that part out. Some people were complaining about the paint on the fins, that's a performance thing. Get that through your head. The more paint on the fins, the less cooling the radiator can actually do. This thing is actually very well built when I went to clean it using primo chill's rad clean which I've used on several radiators. After 2 hours of that stuff sitting in the radiator with an agitator cleaning it out. There was barely any change in the tent of the fluid which means that the radiator was clean from the start. They do have quality control over there and it's really good. I'm incredibly satisfied with this radiator. It's plug options how it fits my case and how well it cools my GPU and my CPU water loop. They also included all the different kinds of hardware for all your different mounting options, and plugs for the holes you don't use.

The radiator came with a good finish and was surprisingly clean inside. I ran a loop of water through it on an aquarium pump with a fine filter for a few hours and very little debris was left in the filter. I will say the 45mm rad is overkill for a single component and you may want to consider a 25mm or 30mm rad for such an application because you will definitely notice the bulk of those extra 15-20mm. Alphacool did a great job with this radiator and the cross flow feature is really nice for running a loop without cluttering the case with unnecessary tubing. I would not hesitate to go with Alphacool again for any radiators or other water cooling products I may need in the future.

Alphacool makes nice radiators. I have this radiator in a custom water cooled pc with an Intel i7-8700k. That I overclock to 4.9ghz for hours of gaming. I never see temps over 55c on the cpu. I put around 100 watts tdp in this radiator and it never gets hot. The water flow with the x-flow design is great. This flows coolant very quickly with very little pressure drop.

I have a XT45 360 and a 240 in a Lian Li PC-O11 Dynamic XL as well as an ST30 360. They work great and I love the cross flow allowing me to spread my tubes out. However, you must be aware of the radiator cap. It extends lower than the rad itself, forcing you to mount the rad on fans, not flush against the chassis. My top and bottom rads are both mounted on the fans (pic1) so its not an issue. The ST360 was mounted against the back and as you can see (pic2) it only just fit with the cap being flush up against the frame. If you're able to mount these rads so that the caps don't interfere, they are absolutely fantastic rads.

Absolutely great cooling capability, I purchased this one along with the same model with the regular ports to put into the new lian li evo case. In total the case has 3 360mm rads. I have a 2080ti and the Temps for the gpu are 30c at idle/ cpu idle 29c. While gaming 46c gpu and 44c cpu. Only gripe is like others have mentioned the plug. I did purchase slimmer plugs but they still raise the radiator more on the plug corner, my fix was simple, I used small spacers in between the radiator and the case on all holes til the plug cleared and all corners of radiator were even.

Well built, Hardly any debris inside when I flushed. This thing is thick with fans so make sure you have the room. Still building so i cant comment on the effectiveness yet but other more scientific people have already done radiator breakdowns and this one ranks high. Also easy to paint and customize. The 6 ports lets you figure out the best config and add things like water temp sensors, or just easy fill and drains. . Love it.

LOOKS AWESOME-ARRIVED AS PROMISED AND IN TIMELY FASHION.

This is the 2nd Alphacool rad of different sizes the screw issue didn't affect my 480mm Rad, but this 360 mm the M3 x 35mm screws are too long and what made have to order a set of different screws because the screws provided only have 5mm of thread so you cant really shorten them why a set of 30mm and thr other set 35mm, I don't know what case has 4/5 mm Thich steel 2 sets of 30mm would have been great or have a 10mm of thread so you can easily shorten them, the Rad is great but the screws let it down.

Super guter Flow mit nur zwei XT45

Leider ein paar Abzüge. Farbe blättert schnell ab. Aber schlimmer ist, wenn die zu verbauenden Fittinge zu fest angezogen werden, dann kann es passieren, dass sich das Gewinde löst und das bedeutet es wird nicht leicht werden, das Gewinde wieder anzulöten. Ich nutze nur die Hand ohne Werkzeug, wenn ich an der Wasserkühlung rum fummel. Ich brauche also keine große Kraft um das Gewinde zu lösen.
