This might be a lost cause, but I’m looking for small & medium (so max 1A and max 2.4A power draw) USB fans without a battery (corded power only) which will last more than 1 to 2 seasons even at a 90% duty cycle. USB fans are a common enough item that unusually good ones may exist, but it’s really hard to find any amid the tsunami of cheap trash.

Yes I’m aware cheap DC motors don’t last, I have my reasons for needing USB powered fans, please do not suggest fans which use AC power.
