I went through a bunch of fans before landing on the Utilitech 20" high-speed fan, which is currently $45 at Lowes:

I tried the Lasko blower-style fans the TR crew likes so much, but for me, the air stream was way too narrow and would require two. At $80 each, that would be $320 for my wife and me…more than we were willing to spend, not to mention the floor space they’d take up.
The biggest benefit of the Utiltech is the amount of air it pushes. And the wind stream is nice and wide. WIth it right in front of my front wheel, I get just the right amount of air on my face and core. It feels heavy duty so hopefully will last a long time.
The one downside is that it’s probably louder than @uxcyclist would like. It has a low frequency, propeller-like sound, but we can still our entertainment over it. Home Depot has a house-branded version of it, but the power cord is a foot shorter.
I also got this remote outlet kit so we can turn on our fans without getting off the bike. When going into a cold room first thing in the morning, it’s nice being able to warm up for 5–10 minutes before kicking the fans on!
