Alphacool today joins EKWB and XSPC (and Dazmode, before) in launching ultra thin sub-30 mm thick radiators for PC watercooling. Labeled the NexXxoS ST25, these are 25.5 mm thick and are the same radiators as those used in their Eisbaer LT CPU AIO coolers. These radiators are compatible with copper/brass/nickel loops, with copper fins and coolant channels, a steel housing, and brass threads on the two BSP G1/4" ports aboard the radiator. The core uses 15 FPI fins, which we speculate are the same fin geometry as with their other NexXxoS radiators with a louvered surface and ~25-30 µm in thickness. The NexXxoS ST25 is only available in 120 mm sizes for now, with prices ranging from 31.99€ for the ST25 120, to 39.47€ for the ST25 240, and 58.49€ for the ST25 360, with all prices inclusive of VAT.
