    Typical Winsinn Fans, Useless Junk
  

*by N***P on Reviewed in the United States 🇺🇸 on 7 May 2021*

These fans are horrible. I was going to use them for a 3D print head, but they sounded like a miniature jet engine and had horrible vibrations. I could tolerate the noise, but thr vibration was severe, and it would not work for my intended use. I ordered a recplement set, but they were also very loud and shaky. Ended up returning both.Avoid these fans if you don't want noise or vibration. It seems like every fan (including some 3010 and 4010 box fans) I have gotten from this seller has been really poor quality. The performance needed just isn't there. I would buy noctua fans if they made 24V models.

    The wires on them are junk
  

*by A***R on Reviewed in the United States 🇺🇸 on 9 September 2021*

Fans both worked but the wires on them both broke off in very short order at the circuit board under the stickers.  I'm pretty decent at soldiering so I replaced the wires with better quality 24ga silicon wire which solved the problem but its a bit small and fiddley to do if you don't have good soldering iron and a steady hand.  If you can't solder shop elsewhere they really are not that good even the dual row bb ones.  Problem is there is little choice unless you want to pay $20 a fan from somewhere like digikey or wait a month for something to come from china that might be the same crummy quality.  I will say they do blow air fairly well and if you keep them around 50% of their max rpm they are liveable until you can get something better for your 3d printer.  They fit the vorob 2.4 print head perfectly btw

    Much louder than original from 3d printer
  

*by M***M on Reviewed in the United States 🇺🇸 on 2 September 2021*

This thing blows like it says but is much louder than original from 3d printer. I know they claim to use dual ball bearings but that is not evident without tearing it apart. The standard 40mm fans that claimed to have dual ball bearings (same brand) died in less than a month of use and upon disection no ball bearings were found just the standard bushings. This blower has lasted several months so maybe it does have the ball bearings but... All in all I give it 4 stars. Price was good but noise level lost it a star.
