Worked, decently quite, good price.If you want something 100% silent, and attractive, maybe look elsewhere.If you want to keep your computer cool without being as loud as a jet plane and spending a ton, these are great.

I bought these a little over a year ago and ran them 24/7 at full speed. They have stood the test of time and worked pretty well! Good quiet fans. I used them for a cryptocurrency mining rig and they cooled my GPUs easily.

used for RV vent fans - 4 per vent - set up to run 4 in parallel or 2 x 2 series. DPDT switch center offthey work at 6 volts- 1/10 amp draw per series run - very very quiet - not much air flow but enough to assist venting12v - still quiet, but noticeable - .155 ma per fan - a lot more flow, not high , but not needed for my useVery happy with them

Worked well for the first year before I had one of the fans stop spinning at normal speed then I started noticing some kind of oil being sprayed all over my equipment and the fans themselves were all grimy. Don't recommend for long term solution or for exspencive setups
