Coolerguys 12vDC Waterproof IP67 Fan (High Speed, 140x25mm)

I can't fault the fan, it did its job admirably. REALLY SILLY POWERFUL. The idea was to put this at the mouth of the drain hole on my freezer I'm using as a refrigerator in the interim when I can afford to replace the 15 year old MONOGRAM that came with this house, already put like 5k in repairs to it, so not really wanting to put more. THE issue was, moisture build up. THE idea was, pull the moisture out of the freezer using the fan. NOW maybe the problem was it was blowing too much air out causing my little temperature probe thing to trigger the freezer to stay on, thus building up condensation inside. SINCE it was way more damp with this little hack than without it. I thought I calculated correctly, 7ft^3 freezer, a fan that can move like 12.3ft^3/ minute might be too powerful. NOT GIVING UP ON IT, since I think the logic is there and I don't know how long those desiccants can last. Also they smell bad. I'll just buy the noctua fan controller for it. Conclusion: Failure for me, but can tell this fan if used properly and in the right size area, would be great for people. I was impressed by its power in such a small size.

Moves a lot of air, a bit loud for what I’m using it for, but I want airflow.

Replaced the fan in my inverter that went out. This fan moves a lot of air. Time will tell how long it lasts. Good so far!

worked enough for what i needed but it was way underpowered from what i expected you can barely feel the air moving

Cooler guys are the best to work with! I purchased from them a few years ago when I picked up a twin pack of water proof fans for the motorcycle oil cooler. This one was for a camper vent, simple and easy to setup and use. Very quiet, I had to look several times to see if it was even running. Make sure to get damping bushings for your screws if you want the most quietness out of them. I will continue to buy from these guys!

I installed this fan in my Davis Vantage Pro2 weather station to aspirate the temp and humidity sensors. It’s been running nonstop for two years in Virginia, with high heat and humidity, rain, below zero in winter sometimes, snow, etc. like the Energizer Bunny, it just keeps going! It’s in the accordion shaped housing in the picture. It doesn’t get direct exposure to rain and sun, but it does get heated, frozen, misted, etc. Addl (too much) info: Davis wants $500 for 24 hour aspiration, with solar cells and rechargeable batteries, holy smokes! I used a Dremel to round off the edges of the housing and fit it into the housing, and ran underground lighting cable to the house to run this fan on a cheap USB 5 volt adapter because at full power (12V) the fan is overkill for my application. Note that at that low voltage, any quality issues are amplified. Bearing corrosion, etc, would have been obvious at this low spin speed. But it just keeps running. I get a super accurate weather station at a very low price point. If it died tomorrow, it would still get 5 stars for the great value!

Bought this to complete my fog chiller. Had another, cheaper fan, but returned it for this one as this one is water proof and will work better in my chiller. Bought the power adapter from CoolerGuys as well and together these worked flawlessly. Just what I needed for a DIY fog chiller. All together my chiller cost me roughly $30 vs over $100 to buy one online and it was a fun project. THANKS COOLERGUYS!!!! Update: Bought a second one of these for my PS5 along with the coolerguys thermostat, both work great together at keeping the temps down on the PS5 that I keep in an entertainment center. Great fans with amazing output. They are a little loud but that’s to be expected with the amount of airflow these things push out.

So this is my second $20 fan I bought. The first one I had I was testing in my hand to really see if the output was adequate and while it was spinning, My finger ever so slightly grazed the blades. It exploded! Only one blade didn't snap off and to be honest, in all the computers I have built and all the fans I had played with in the past, I have never had one so fragile. So why did it explode instead of just slowing down? Well the blades are incredible stiff, probably to reduce the vibration do to the high rpm's in order to get the high cfm's. But the problem is any and I do mean ANY disruption and it explodes. So I bought a second fan. I wanted to use this in conjunction with my chicken's hen house to serve a a ventilator running straight off a 20W solar panel during the day to move air around when the hens come back in to lay eggs. I learned my lesson and got a protective screen/filter on one side and a wire grill on the other as you can see in the pics. So while outside trying to determine a mounting location, I hooked it up to the solar panel and spun it up. Perfect now my fingers are safe. Well while only making slight movements trying to optimize the directed air, the 2nd one exploded after the blades contacted internally. I don't know if the blades hit the frame or if they hit one of the protective screens I installed but at this point it is irrelevant. The fan is is basically unusable (even if it wasn't broke). So in a perfect world, you can install this and hope it doesn't see vibration or movement and then yes it moves tons of air. But this type of cooling fan and the high noise level leads it to be a project fan and not a computer fan...Which is where it fails. Remember, I spent $20, broke it, then spent another $35 (for the 2nd fan and fan grills/filter) with high hopes to put it to use. Now $55 later I can't even return it due to the unusually short return window. You have been warned. Just find something of better quality.

The fan is super noisy…over 70db. I’ll need to find a quieter one.

Works as intended.

Fan is more powerful than my stock fan but little noisy which annoying. Must buy.. Thanks a ton 😊💯

I installed this fan to cool the vents behind the fridge in our RV. It’s still going strong 3 years later.
