Review on Enhance Cooling Efficiency with UpHere Airflow Coolers Radiators 6 Pack, SR12 06 6 by Kofi Wills

I installed 5 of these fans and they barely vibrate. However, some buttons on the remote control are unresponsive, no need to worry. However, the cruise control doesn't work either, which is handy. Hence 1 star deducted. Update 9/27/2021 It's been a little over a month since I received these fans. I've since put the 6th on and these fans have been running for about a month now. Two fans, the backlight does not change color or turn off. The other four still work perfectly. But the remote is totally useless as the only thing that works is turn the light on and off and change color, that's all. The fan speed control doesn't work at all, which is the most important feature. So I'm deducting two more stars.
