Review on 🔵 ANVISION 24V 40mm x 10mm Brushless Cooling Fan, Dual Ball Bearing, YDM4010B24 - Pack of 2 by Dustin Wright

Cable length is only 6 inches from connector to 24V fan (40mm x 40mm x 10mm). The 2-pin connector was the right size, but it took me at least 7 1/2" to get to the connector on the board. I bought it because it claims it's quiet and quiet! I can't hear it at all, and if my APC BackUPS power supply had failed the self-test, I wouldn't know it was powered on. Really! Instead of sending it back, I decided to connect the wires to the wires from the original fan, which caused an amazingly loud alarm on my backup -Battery APC BackUPS 900 tripped.I was afraid of such a need.But uxcell is too loud with constant hum.So I order this brand to see if it is quieter.He is not heard!If my UPS with APC- Battery backup had failed the self-test and I had unplugged it to test its battery backup abilities, I wouldn't know it was on! Plugging it in was worth it (solved tet with shrink tubing).
