🌀 Coolerguys Ball Bearing 12v 3pin Fan: Compact 40x20mm Size, Medium Speed Efficiency Review

It moves air but you don't want to be in a room with it. A few vibrations, but that's nothing compared to the gale force wind and the screams of the banshees. Great fan for $7.

Reliable fan, pumps a lot of air, not too loud, long cable. They have been around for over twenty years and I first ordered from them over 15 years ago. Since I ordered this fan I placed another order with them directly through their website. You have to pay for shipping and it takes a little longer, but all items are cheaper than Revain so you're still saving money.

Moves enough air for its size. I hope this lasts for several years. With a slight modification, it is ideal for 1.5 inch drain pipes. Will keep my bathroom fresh for a lifetime fan.

Very quiet fans but I use high speed fans as they don't deliver enough air for my liking. They were used to replace the incredibly noisy campervan fridge fans in my caravan, don't get me wrong, they work and do a great job, but the unit feels a few degrees warmer than before and I'd do much with more air feel better . move along the coils of the refrigerator.
