Alphacool NexXxoS ST25 Full Copper 360 mm Radiator Review

It seems my reviews of the new Watercool Heatkiller radiators generated more interest than I thought, as other companies have voiced interest in having their radiators covered. Bykski was the first to respond, and the 30 mm RC series proved to be fantastic value for money. The USP there was the use of the so-called red copper rather than brass for the core, which Alphacool has touted for a while now. Indeed, there is a recent video put out by the brand to help solidify these claims, but previous tests all showed not much had been gained in either Alphacool's or Bykski's case thermally. This does not mean the brand has stopped putting out new radiators, and both have sent some over my way for testing.

I was about to write that we had previously covered Alphacool radiators until I realized we actually had not. That was all elsewhere, on my old website, and I had only tested a couple of spare radiators I had when I decided to use the triple 120 mm size for radiator testing on TechPowerUp. One of those, the Eisbrecher Pro XT45, was a novel design that did not get used again. It was also the start of Alphacool deviating from its largely successful formula of naming radiators NexXxos + two letters to denote the radiator thickness (ST for 30 mm, XT for 45 mm, UT for 60 mm, and Monsta at 85 mm). The subject of this review is an ST-class radiator, and as the name suggests, the newer ST25 should be 25 mm thick, which is the case since it is 25.5 mm thickness. Let's thank Alphacool for sending the review sample before figuring out whether this low-profile radiator is the one for you.
