Review: Excellent cooler. Check your wiring and test before buttoning up the case. - Excellent product that works very quietly and drops the temp on my CPU very well. Straightforward to install, good instruction leaflet. Only caveat is that there is a connector for the fan that carries both fan power/RPM and the RGB power and signal. (I don't use the RGB stuff.) It IS possible to put the wide connector for that cable in backwards, which keeps the fans from working. It would be better if that cable was separated or used a keyed connector.
Review: Highly recommend. - This cooler does a solid job overall. Temps dropped noticeably compared to the stock cooler, and it runs pretty quietly even under load. The aRGB lighting looks clean without being over the top, and installation was straightforward. My only gripe is that the water lines are not quite as long as expected, though this is mostly a build problem with my case. For the price, it’s a dependable liquid cooler that performs well and looks good doing it. The fans seem nice and wuiet as well. I think it will last longer than my older cooler.

### ⭐⭐⭐⭐ Aire atrapado
*by O***N on 11 March 2026*

El producto llegó en buenas condiciones, es fácil de instalar y se ve muy bien. El único inconveniente es que, cuando recién lo instalé, de vez en cuando producía un ruido de burbujas por aire atrapado; pero, según ChatGPT, es normal en AIO nuevos y ese ruido ha ido disminuyendo.
