These are trash. Bought 2 and 1 was entirely dead. The other doesn't always run. Very low quality and zero quality control from supplier

Powerful yet quite. Fan seems lighter than other fans I have and it looks good. Fan is high quality.

Loved the fan and especially design, however it quit working after 2 months. Emailed Ruddug, no response...

Made it through one day of racing. Fan blade fell out of the housing during the second day of racing.

What reviewers say

Eight verified-owner reviews give this 40mm aluminum high-speed cooling fan an average rating of about 3.6 out of 5. Reviewers consistently praise its airflow and cooling power, with several noting it is quiet and well made. The main recurring problem is reliability: two reviewers report failures, one a fan that was dead on arrival and another a blade that came out of the housing during racing, and a third reports the fan stopped working after two months with no response from the seller. Opinions on build quality are therefore split between those who see it as high quality and those who report early failures.

  • + Strong airflow and cooling
  • + Quiet operation
  • + Attractive design
  • + Good build quality for some owners
  • − Reliability failures reported
  • − Units dead on arrival
  • − Blade came out of housing
  • − Unresponsive support after failure
