    Pros: Small, fits in my sandwich itx build Cons: Dang this thing can’t even cool a ryzen 3600 at stock speeds. If I try a burn in test it jumps immediately to 80 C. Overall Review: I really expected it to perform better than a stock cooler but it doesn’t

    Pros: Super small and highly effective, it would fit pretty much anything even a 1U server rack i bet. Cons: You can’t reverse the fan. The holes in the fan don’t allow for it. I know this may make cooling worse for most people but in my tiny 4L case if the fan was reversed it would be blowing all of the hot air out of the case. I don’t think its great to be puling the air down into the case when there is no other airflow in the case. Overall Review: Don’t listen to that other guy. Lord only…

  3. Bryan H.

    Pros: It is a very low profile product, that noticeably outperforms the included box cooler. Cons: The fan does need to spin up a fair bit when under load, which is audible. Still runs quieter and cooler than the included box cooler. Overall Review: Great upgrade from the stock cooler for cramped cases.

    Pros: – Excellent fan and cooler – Silent running – Looks great in Mini ITX build Overall Review: Great upgrade for system – especially in SSF cases when the stock cooler is too large. Keeps my machine at the same temp or better than the AMD Wraith cooler.

    Pros: can keep a R7 3700X cool under gaming loads (max during GTA 5 is like 70C) 100% ram compatible Cons: not sure if its a loose screw or my fan config in the Lian Li 205M but i dont think its bad Overall Review: i recommend this product
