Alphacool Launches New Core XT45 Full Copper Radiators

The Alphacool International GmbH, based in Braunschweig, Germany, is a pioneer in PC water cooling technology. With one of the most comprehensive product portfolios in the industry and over 20 years of experience, Alphacool is now expanding its lineup with the Core XT45 Full Copper Radiators. As the first models of the Core Series, the Core XT45 radiators combine Alphacool's trusted full-copper construction with a completely refreshed design. The clean, modern look can be customized using interchangeable side panels - available either with integrated aRGB lighting or in a classic, unlit style. Thanks to the magnetic mounting system, they can be swapped quickly and without tools at any time.

Inside, Alphacool continues to rely on full-copper components throughout all water-carrying sections for maximum thermal efficiency. A redesigned internal layout with 16 water channels instead of 12 increases performance by improving both flow and heat transfer. For easy installation and handling, the radiators are equipped with two G1/4" ports in the signature Core look. An additional fill/drain port ensures easy integration and simpler system maintenance.
The Core XT45 Full Copper Radiators are now available in the Alphacool Online Shop.

Features
  • Full Copper Radiator

Oh no, RGB radiators :(

Soon we'll have RGB thumbscrews.

At least they're still making non-RGB versions, too. I was very happy with my NeXXos XT45.

Alphacool had a big problem with shoddy fin soldering, see here:
BoggledBeagle in Alphacool - problem with radiators - bad fin soldering?Recently I tested cooling power of the following Alphacool 480 radiators and got these numbers (Watts, one layer of P12 fans at 100% and 10°C water over air temperature): Alphacool NexXxoS HPE-30: 455…
I hope they fixed this issue and when they redesigned the rad, they made sure, that the fins are soldered properly.

I hope they are not just putting RGB glitter on a tu*d.
