Wathai 75mm x 30mm 12V Blower Cooling Fan Dual Ball 12 Volt DC Centrifugal Fan 2pin for Amplifier RV Fridge Computer Case Ventilation or Project Replacement Part kit

I purchased this to move air around in my cabinet humidor and it does the job well. I do not let it run all the time. I turn it on now and then when I pass by and let it run for an hour or more. I would buy again.

Well worth 8$. Not too loud and moves some air. I placed it in my PC case at bottom to pull some hot air out from bottom RAD and SFP+ card.

These work well and are super quiet although they were not powerful enough for my application they did work good

I'm doing extensive experiments on 'overcooling' a highly modified Acer mini PC. This fan almost ties the best of various compound fan towers I have tried to pull air out the cpu exhaust vent. I have an upgrade I5 quad core in here with other mods and wanted to get temps down. Problem is pulling air through the tiny vent stalls fans bad. I have like 8 revisions of box fan towers, compound blowers with experimental features to prevent air rotation and stalling over the blades. My best was a high speed 60mm in a trapezoid tower to a 90 mm high speed. This one fan is really close to matching it. I love the fan performance. It's not as noisy as the tower and comes close to the same temps. I WILL buy from this seller again and I'm dying to try a compound puller arrangement with this product. First pic is their fan and second pic is the 8th iteration compound tower it has temp replaced 8~D

Good fan not to noisy 12v .. Note if your replacing something that was noisy and realy pushes air don't get this one. This fan is more like that crazy fan at half power. Nice volume of air output for it's size but NOT hard driven like most valuted fans.

These little fans work great for car audio. They move alot of air. Just cut the end piece off, and hook positive to remote ace ground to any ground.

This fan is terrible. When I first plugged it in, it worked great, nice and quiet. Within 24 hours, it was screeching from the bearing making noise. This is not acceptable. I knew it was made in China when I bought it, but it seems impossible to get a quality fan like this that is this size. I guess I will try another random one, but it seems they are all from the same factory. Update 5/14. Thanks company contacted me to replace the product. They have sent a new product, I can at least give customer service a 5 star response, and am hopeful the new fan works better than the first broken one. If the new one works without issue I will update the review to 5 stars, but for now, I will stay at 3.

My air purifier started making an annoying grinding noise. I opened it up to see if I could fix it but lube and manipulating the fan wheel didn't help. I paid $70 for the purified so I figured another $10 to replace the fan was worth a shot. The hardest part was taking the purifier apart to remove the fan without breaking anything. Once open it was a simple process to remove and replace the fan. I did have to remove the bottom part of the fan housing (see pic) to match the original fan but that shroud was manufactured in 2 parts that snap together like a shell so that was easy. The new fan housing did not exactly match the old one but close enough. I had to snip some of the plastic tabs off so it would seat a bit better.

I have a caravan refrigerator that seemed to be a bit variable in keeping all the contents cooled, due in part to a buildup of ice on the freezer plate. Based on the idea that domestic fridges use moving air to be frost-free and to make cooling uniform, I thought that I would try something similar with the van fridge - so I purchased this fan. I found a suitable mounting place in the bottom/rear of the fridge above the crisper drawer (blowing upwards towards the freezer plate) and wired it in with an inline switch to provide on/off control. This required a small hole to be drilled (with trepidation) in the fridge cabinet to run the power cable - along with a rubber grommet to prevent wire chafing and to ensure no impact on insulation. The final effect was in line with my expectations- the ice buildup on the freezer plate was substantially reduced and the temperature variation in the fridge was improved. The fan is very quiet and cannot be heard when the fridge door is closed. The fan runs 24/7 and draws negligible power. All in all this fan provided a noticeable improvement in the fridge performance and I am happy to put it down as a successful experiment.

Silencieuse et efficace Elle très petite , excellent achat pour mon application.

It's a 25mm fan, and the speed is even worse than Wathai's 15mm fan. Why is it like this? ======================== Update: The company quickly corrected their inventory and sincerely apologized for the wrong units with full refund. The third unit I got was a correct 30mm fan with output of 1240+ ft/min.

stopped working after 7 months, real shame since it was great before it died, I want to add to my previous review, because the company contacted me and said they will replace the item which is fantastic customer service, but there is a small issue in that when I didn't hear anybody's response for over a week I threw the unit out so there is nothing to send back. I did just go online to buy another one because the last time I tried they were unavailable, but now they're available for $39 whereas I paid 17, ouch.

Powerfull but sounds loud
