Super, that made it possible to supplement perfectly the setup carried out, with the compliments of madam.
The fan was installed on a Pure Rock 2 RAD without any problems. (in fact it becomes a Pure Rock 2 FX)
The circle of light created and synchronised with the rest of the case fans and the motherboard is discreet.
I'm not sure it's enough for a front case fan, for example.
Although not essential for the colour, the fan cools a Ryzen 7 7000 very well
