GDSTIME 2 Pack 80mm x 80mm x 25mm 12V DC Brushless Cooling Fan 2Pin

Very quiet fans and work great.

I bought these to use in my teardrop camper. Specifically, the AC is a fully enclosed wall unit that has ducts to pull air from outside, channeled across the heat fins, and out through another duct to keep the unit cool. Out of the factory, the fans they have installed are not well designed (in our case, the exhaust fan was installed in the wrong direction, causing heat to spill out into the cabin). I 3D printed some brackets and put these in place to enhance the air flow so the AC could be cool without being a heater at the same time. They are really quiet, move a lot of air, and after they were installed, the exhaust outlet now feels like a hair dryer. The air conditioner runs smoothly in the summer heat with no heat leakage back into the cabin, and all of this without breaking the bank. If you need small fans that will quietly move a lot of air, these will fit that bill.

I used these in a Red Bull fridge I obtained recreantly. The original fans are loud! These are whisper quiet and move air! Very happy with them!

We've been struggling getting our RV black tank to vent on windless days. We installed this fan to blow over the pipe 24x7, and it works like a charm. No more sewage odors back filling into the camper. We installed it with water protection. It's 12 volt so hooked up to a fan switch. I didn't think we'd ever did this problem and spent a bunch on money on other things connected with the black tank to no avail. A cheap fix that works beautifully

I got these for a non electronics application. I needed an ultra quiet fan for my deer stand to circulate the heat and keep the windows from fogging on cold days. They worked better than expected and are ultra quiet. A great little fan for the price.

Simple 12vdc connection with no computer controlled controls required for the fan. I hot glued a temp. controller to the side and connected it to a 12vdc battery. It comes on at 90* F and shuts off at 85* F. I charge the battery with a small solar charge controller. No inverter required because it's 12vdc. Two of them do an adequate job of keeping the storage shed from getting too hot in the summer.

Super Quiet Fan (did I say QUIET)! Fixed my noisy AOBOSI fan. Wow, a super QUIET fan .... I love it !!This is one of two fans I replaced in my Wine Cooler/..

I can't speak a ton on the longevity but so far they do what they are supposed to and pull a lot of air. Good metal grates too.
