## 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 Radiator Cooling is excellent - Upgraded from 240mm alphacool st30 in push/pull to this alphacool xt45 xflow in push only. I am very happy with the performance. Temps are more stable at full load. The 100% copper design is really excellent quality. Would recommend alphacool rads to anyone.
Review: Couldn't be happier - The stigma behind x-flow radiators needs to be put to bed. This one rocks, great flow and keeps everything super cool while OC'ed. The approach behind this type makes for some very logical loop plumbing cutting down the need for excess amounts of fittings and tubing. Because of this design I was able to go with a 420mm over a 360mm too.

### ⭐ Materials could be better
*by X***L on April 13, 2020*

Well it just came today. The delivery is fast considering all that is going on. The low star is due to the quality for an 100 dollars radiator. The paint around my screw chipped. I only found out about it after I have to remove my fan to swap the fan wire direction. The frame metal is not copper. I guess it’s ok since the chipped off area is just used to mount the radiator. It’s a bit light as well. Lighter than my EK 60mm 360 rad. I was expecting something similar since this is a 45 mm 420 rad. I’m not sure about the fin metrical. I know my EK 60mm 360 rad have copper fins. So take a guess.
