Effective but difficult to assemble
Once attached, the ventirad gives an impression of reliability and robustness.
However, I had to figure out how to install it on the motherboard AMD: the instructions suggest that it clips on (without any other details), whereas I first had to unscrew the plastic parts already installed on the motherboard to be able to place the ventirad. From there, screwing on these parts ensures a perfect fit.
Less accessible than the fan screwing system AMD, but effective in the end.
