GDSTIME 60mm x 60mm x 25mm 12V 2Pin Dual Ball Brushless DC Cooling Fan 2Pcs

I have at least 25 odd size 40mm to 140mm fans for additional cooling to solar charge controllers and power inverters. I use these fans for primary cooling and allow the internal fans for backup. These new fans have very high flow and are using a speed controller to slow down speed and noise. Best china fans for the price.

Work perfectly. They move lots of air. The noise level is what I expected (it moves so much air that it has some volume…. Fine for me

These fans move some air! And they are LOUD!! The PC is located on the end of my desk. A decibel meter app reports 63db sitting in my chair three feet from the PC. 83db 6" from the fans. My office sounds like a server room. So they're loud. But two of these are installed on the rear of the case, no fan on the front, and a piece of paper is drawn to the front grill. These guys are air movers. - djb

These fans are super quiet and very efficient. I had a very minor issue with my units after a few months and the company replied to my query very quickly and provided replacement units without any aggravation. This is the way all companies should operate. They have been very friendly and great to work with. My highest recommendations for this product and this seller!

Fans are decently, quiet and provide enough airflow for my trailer exhaust application. Easy to wire up. I had to drill the holes at the corners a little larger to fit my screws, but that did not cause any issues. I feel that these fans should last a while because of the ball bearings.

fans work well. I bought this set because I needed to replace the fan inside of my kebonnixs incubator because my fans bearings were going out after running non stop for 2 years. The fan works great installation was pretty simple other than the fan having a much longer wire, I had to wrap the wire around the fans body to get it to fit under the fan housing. so far I've left the incubator run for a solid two days with 75% humidity and it seems to work fine if anything that works better than the stock fan

Used these to move air from the camper living space into the cabinet spaces holding the water tanks and waste tanks. This simple solution keeps the tempature up for longer camping is the shoulder season when team-tires start to freeze.

I took three out of the four ordered and used some couplers (Amazon as well) to bind them together. Then I put them in a vent with a spring-loaded flap to use as a vent for one end of my 40' shipping container. It is controlled with another Amazon purchased thermostatically controlled switch/relay. A passive 8x8 inlet (Amazon purchase) is on the opposite end of the container. It works very, very well. It kicks on at a preset temperature and off once below that threshold. The three of these little guys move enough air that if you are in the middle of the container between the inlet and this active outlet, the airflow it creates will move your hair slightly. Highly recommend!

I got my ordered delivered today 22/10/2022. I got only one fan instead of two and there are no screws or nuts. Also there is no metal fan grill, i didn't even get one . This going to cause delay in my submission for my school project and im so disappointed. The fan manufactural is different, im suppose to get GDSTIME and but i got CHANKO.

I used these for a camping fridge. They use half the power of the older fans they replaced and were a good fit in the existing structure.
