Review on 🔥 High Speed 24V Hydraulic Bearing Brushless 40mm Fan (Pack of 5Pcs) by WINSINN by Clint Miller

bought these fans for a DIY computer project. installed 4 of five and in less than a month of light use two of them started making a horrible grinding noise. If I tapped it a few times, the noise stopped. I contacted the seller and although I wasn't in the return window they replaced my fans for free. I wanted to leave fewer stars but it was difficult because the seller replaced bad fans for me. I just hope it was just a few bad fans and the rest survived. For the price and working with suppliers, they work quite well. *UPDATE* - These fans are absolute junk, don't waste time, the company quickly sent me a new set of five as I had two of these that started service in less than a month, so I got new fans and installed, and i've had to work harder so i've had to replace almost every last one, one every two weeks since i bought them and eventually i'll have to go back to buying better fans and replacing these so maybe the hour of my life i've spent fixing them tapping to keep them from grinding and eventually replacing them with new ones when tapping stopped working, i will never in my life get that time back. issued. Save the time of your life and buy the best fans from the start. Happy the seller replaced them all, honestly it was nice of them. Maybe I got two bad batches. good customer service
