Review on 🌬️ WINSINN 50mm Fan 12V Brushless 5010 50x10mm - High Speed (Pack of 5Pcs): Efficient Cooling Solution for Electronics and Computer Systems by Larkeese Casiano

Bought 5 of these to bleed our wine cooler. Using Nano and FET/NRF24L01+ for remote monitoring, I control RPM based on temperature. Above 75F they run at 100% load. If the temperature is < 75°F, they will work at 60%. The wine cooler is hidden where the trash compactor used to be. Peltier heat pumps need space to dissipate heat, otherwise they can burn out. With 4 of these fans, the wine cooler will be happy. They move a lot of air for their size. However, after 8 months 2 out of 4 stopped working due to dust and cat hair. Yes, pulled from the bottom to the top of the device. Didn't expect that. Cheap enough so I bought a few more and replaced 2. Runs 24/7/365, expect fans to stop working. Two-zone wine coolers are slightly more expensive. 4 The fans do their job. Pretty calm. They hum a little when you reduce their power by 60%. Otherwise it was a good project.
