Good performance, fasteners a little less...
Performance and RGB are up to scratch and deserve 5 stars. On the other hand, the attachments between fans, although well thought out, and similar to the lian li, are very useful for avoiding cables everywhere and giving a better look.
On the other hand, they are prone to blowing up sometimes (this can only happen in certain cases, not everyone) and this makes the whole thing very frustrating very quickly.
A little research on the internet indicates that this can happen if the radiator support is not perfectly straight, which would make the attachment less stable... I've found a temporary and not very elegant solution for the moment but I'm going to have to think about a longer-term solution, so check before you buy... The lian li, on the other hand, don't have this problem because they use a different method of engagement, it seems to me... A par ce petit défaut les ventilateurs en reverse sont excellent et poussent beaucoup d'air, le pc a gagner un bon 4 degrès comparé aux nzxt et sont bien plus silencieuses.
I can't recommend it enough.
