Review: Worth the money - Worked good
Review: Longer than the regular radiator - It functions well as a radiator, but be warned that it is longer than the regular 420mm radiator that isn't x-flow. I had to upend my entire water loop to barely make enough room for this in my system. I use a NZXT H9 flow and this radiator does NOT fit in the front where 420mm radiators are supposed to fit.

### ⭐⭐⭐ Review
*by R***. on July 31, 2018*

Leider ist der Radiator 3cm größer als normale 420er ohne X-Flow. Dadurch passt er nicht unbedingt in eine 420er Halterung rein. Verarbeitet ist der Radiator gut, der Wärmeabtransport könnte jedoch besser sein. Das einzige Manko sind die Schrauben: Die Schraubenköpfe haben einen Innensechskant und "nudeln" sehr schnell aus. Dadurch musste ich eine Schraube bereits nach zweimal einschrauben austauschen. Auch die Löcher sind nicht wirklich gut gebohrt. Davon ab, ist der Radiator nicht schlecht.
