## Description

Alphacool has been a trendsetter on the scene for developing and improving radiators for years. That's why these models are among the first radiators to really earn the descriptor "full copper"! All the main elements, not just the fins and channels, but also the channel heads are made of copper. Material-wise, this is a big advantage, and one where other radiators fall by the wayside. The Alphacool NexXxoS X-Flow radiators set themselves apart significantly from conventional radiators in their construction. The X-Flow radiators are built for high flow rates. The slanted copper chambers on either side are built identically. This means the water can flow through all the channels at the same time until it flows into the opposite chamber and leaves the radiator. Freedom in the installation is one of the central points on which Alphacool's development department focused. Fewer angles are needed, which increases the flow rate and offers more options in the installation. The installation of the radiators, as well as the fans and radiator faceplates, is easy to do with this series: the M3 threads are standard in the radiator sector, affordable and available in all lengths. Even the dreaded mishap of turning the screws in too deeply won't lead to costly damage with this radiator: an inner protective edge stops the screw before it can come into contact with the fins. The fin spacing was chosen so that the radiator could reach its optimal cooling performance even with slow or medium-speed fans. This is not only comfortable in terms of background noise, but also puts no constraints on the choice of fans. Model: 14246

Review: Fantastic Customer Service - 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!!!!
Review: Great performance for me - 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

### ⭐⭐⭐⭐⭐ Incredible
*by C***R on February 4, 2024*

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.
