    Very quiet fan

    This fan is particularly quiet and comes with all the mounting hardware needed to fit the most common processors and motherboards.
    Be sure to check its compatibility on the manufacturer's website with the processor you plan to buy.
    Don't forget to check the dimensions of this product and the available space inside the case; it is mounted perpendicular to the processor.
    The case manual specifies the maximum acceptable fan height.

    Horrible cooler installation

    On my Gigabyte B650 eagle AX motherboard, installing the cooler is impossible. The spring-loaded screws cannot be aligned with the screws built into the metal mounting bracket, despite all my efforts to line everything up. This should not be necessary just to install a cooler.

    Excellent quality

    Since I had my PC repaired at LDLC, I haven't had a single problem with it! It was also a good product choice for my budget.

    Great

    Nothing to report, it does its job without any issues and is ultimately quite quiet.

    I highly recommend it.

    As usual, effective but...

    As usual, I am satisfied with the effectiveness of the CPU cooler, but the cable provided for the RGB connection is 10 cm too short... So, as of today, lighting the blades is not possible. I have to find a replacement or extension cable... I would prefer them to sell it for 2€ more with a cable that is long enough...
