GDSTIME DC 24V 60x60x20 Axial Fan GDA6020 Dual Ball Bearing 5000RPM 1.7W 0.1A XH2.54

A little louder at full speed than some of the other fans I have used, but just as much airflow if not more. Great fan overall.

Been running two of these for controller board cooling voron 2.4, Def not quiet but work great.

While the GDSTime fans are not the best fans money can buy, they are very much good enough for almost all Voron usage. I used these in my electronics cooling skirt and chamber exhaust on my V2 and none of them have failed, so no idea how long they'll last. In other sizes, the GDSTime fans didn't quite last as long on average as more expensive fans, but they lasted well over half the time as fans that cost twice as much.

Since these fans don't mount in the chamber, and aren't subject to elevated heat, I fully expect them to last a very very long time.
