    Effective product

    Clean finish, I like these bequiet fans, quiet and efficient.
    One negative point, but it's difficult to do otherwise:
    the central fan is not that easy to install, you have to be careful not to damage the blades, and you have to do it in position because otherwise you can't access the screws underneath.

    Adequate efficiency but "noisy"

    Switching from a smaller Noctua cooler (NH-U12S), with my 9600X the temperature difference is noticeable (78°C under load with the Noctua compared to 73°C with the Pure Rock PRO 3), but the noise is much more noticeable. These Pure Wing fans are by far the noisiest in my entire setup. I'll have to try other fans, but for this price, there are better options elsewhere.

    satisfied

    The unit was well installed, quiet, efficient and sufficient, and the work was neat and clean. Longevity remains to be seen.

    Does its job perfectly!

    I didn't want to go for watercooling and this ventirad does the job perfectly!
    For a limited budget I recommend it!

    Fragile

    Since I keep receiving reminders to give my opinion, here it is... Item ordered online.
    Be careful when fitting it, it's tricky to tighten and the fan support can break.

    In the shop, I was advised to contact customer service to arrange for it to be returned.
    Customer service wouldn't do anything... apart from advising me to check with the manufacturer... (who of course told me to check with LDLC). It's great
