🌀 WINSINN Dual Ball Bearings 40mm Fan Brushless Cooling 24V 4020 40mm20mm - Pack of 2Pcs for Efficient Cooling Solution Review

My stock Sidewinder X1 fan broke, they work but the bearings are a bit noisy. The main disadvantage is that the cable is very long. Ok if you need it, but they were 3 or 4 times the length I needed so I had to cut and solder the wires to make them shorter.

Bought this because I needed to replace the stock fan on my CR6-SE and it works great. The fan is loud, but serves its purpose.

The packaging was good but when the fans were removed from the box the wires between both fans were tied together and broke where they connected to the fan. Very disappointed.

The thing blows as written, but much louder than the original from the 3D printer. I know they claim to use double ball bearings but that's not obvious without disassembly. Standard 40mm fans claiming to have double ball bearings (of the same brand) died after less than a month of use and no ball bearings were found upon opening, only standard bushings. This fan has been running for several months so may have ball bearings but. In general I give 4 stars. The price was good but the noise level…

The fans both worked, but the cables on both broke on the circuit board under the stickers in no time. I'm pretty good with soldiers so I replaced the wires with a better quality 24ga silicon wire which solved the problem, but it's a bit small and cumbersome if you don't have a good soldering iron and steady hand. If you can't solder the magazine somewhere else, they really aren't that good, even double row BBs. Trouble is, there's not much choice unless you're willing to pay $20 for a fan from

These fans are terrible. I wanted to use them for a 3D print head, but they sounded like a miniature jet engine and vibrated horribly. I could bear the noise, but the vibration was strong and unsuitable for my purpose. I ordered a number of accessories but they were also very noisy and wobbly. In the end I returned both. Avoid these fans if you don't want noise or vibration. It seems that all the fans (including some 3010 and 4010 box fans) I received from this seller were really poor quality…
