    from completed build First mini-ITX build

    Good cooler, keeps my Ryzen 5 7600X under 80°C and fits in a mini-ITX case. Thermal paste wasn't very fluid though, you could probably buy some.

    Decently easy assembly. (am5) Cools my 9800x3d more than enough. Fans were a bit loud for my liking, but still much more silent compared to my last PC.

    It's big, it's a little awkward installing... but it's effective and pretty with RGB fans! And for $35??!?!? Fantastic!

    from completed build First Home Server - NixOS

    Super smooth and quiet, both when idle and under load. Sadly, the motherboard's UEFI menu didn't let it run at zero fan speed, even after going through what Asus calls 'Q-fan Tuning' (which tries to detect the lowest supported fan speed for all fans). The lowest it let me go was 15%.

    Installation was pretty straightforward. The fan comes with thermal paste, so you don't have to buy it separately. The fan cables also have adapters to daisy-chain them. However, the heat sink has sharp fins, so take care not to cut yourself (which happened to me 😅).

    Working just fine, quiet too. That's why it's always recommended.

    Easy to install and keeps things cool. Kept a 7600x at 85 degrees in Cinebench in my most recent build.

    You will not regret getting this cooler. Inexpensive, but extremely powerful. Will keep your CPU cool through a camel ride through the sahara! Excellent price to performance

    One of, if not; the best Air cpu coolers on the market.

    This is an incredible value product, keeping my Ryzen 7 7700X CPU down to a cool 64 C even under a full gaming load. Two cooling towers, two fans, and 6 heat pipes connecting both towers for a very low cost of under $CDN 50 which both undercuts and performs just as well as similar two tower air coolers from more well-known brands. Highly recommended.
