I never write reviews for products unless I’m really blown away… this little fan is a kicker! California heat wave had me and my dog basically sleeping in a hammock outside most nights. Just hooked this thing up and out it in my window and holey cow I swear the apartment cooled off by at least 10 degrees. Buying another one right now!!

i was using a laptop cooling pad since i bought my new laptop (Gigabyte Aorus 15p yd with RTX3080) some 5 months ago and always felt it dont meet the demands for my new machine. i researched extensively for a decent cooling pad but couldnt fine one than i stumbled upon this thing. It certainly is very helpful for cooling the laptop while gaming. At max speed it gets loud but thats kind of expected so it doesnt bother me as i concern more about cooling the machine. While running at max speed i notice temps drops right from 80 to 70 and if there is AC running in the room it will cool further 5 degrees and thats when i play RDR2 at 1440p max settings on external monitor and it stresses the machine to its limits. I usually play BF1 besides RdR2 and this fan keep the temps between 60-65 range while my cooling pad keeps it at 70-75 range. Posting some pics so you could get an idea how big are the fans as they easily cover half of my laptop size so they basically covers all of the back panel.

I recently bought the GDSTIME Big Airflow 3 x 120mm Fans, and I’m pleased with its performance. The fans effectively address heat and moisture concerns during warm showers. What I appreciate most is how quietly they operate, creating a comfortable environment without unnecessary noise. Overall, it’s a solid solution that gets the job done without any fuss.

I added these fans to the top of my outside refrigerator vent in my RV. They increased to airflow sufficiently enough to keep the refrigerator cold even in 100 degree weather. I was able to cut off the cord from the transformers and wire it directly into the 12v system of my RV. I highly recommend it if your RV refrigerator is having a struggle keeping things cold

My server closet was overheating and I had a limited amount of space between two beams to fit fans. (For example, a much more expensive solution I considered from AC infinity wouldn’t fit.) This three-fan unit turned out to be the perfect solution. I cut through the wallboard on both sides and just barely was able to fit this product between the beams. I used white duct tape to make an ad-hoc duct between the two sides, placed this fan in the middle, and put duct covers on either end. The power cable was able to squeeze between the slats of the cover. This solution completely solved my problem, dropping temperatures from the mid-90s ~~with the closet door open~~ to low 80s with the door closed. I’m using it on its lowest setting and its very quiet and moves plenty of air. The only possible change I’d like to see is an even lower voltage setting on the fan controller to be quieter/less air, but maybe there’s a minimum voltage to get the fans moving.
I also received some great customer service by emailing the company directly (they provided their email with the unit). Very positively impressed, and won’t hesitate to use this product or this company in the future.

Easy to take apart and put together in a 2×2 pattern. Lots of airflow! It can be quiet or sound like a swarm of bees on max haha. Either way works great.

One fin broke of my old Holmes fan and I decided to try this one instead. It works surprisingly well with much lower noise level even on full power. The air flow feels the same. And it has a similar price. Not sure how long it will last, regular fans are dying every 1-2 years for me anyway. It requires some assembly, nothing too bad just several screws.

So I decided to make a Corsi-Rosenthal box but I’ve owned box fans in the past and they are loud, like really loud, and big. Also the look of CR boxes made with them aren’t the most attractive.
So, I looked up CR boxes that used different fans, but I also didn’t want to use a ton of tools.
This fan can go in either a 2×2 or a 1×4 configuration – I went with 2×2, which is basically a 10 inch square.
With a phillips head screw driver, a pair of scissors, a roll of 2 inch duct tape, 5 merv 13 10 inch filters and two 48 inch by 1 inch dowls (cut into 3 16 inche dowls each), and 8 rubber feet I came up with this…(see pics).
Basically a cheap 20 inch box fan uses 55-75 watts and is about 55 to 65 decibels (or more if it’s really cheap) depending on high, med, or low.
They do move about 1,100 cubic feet per minute (which is good).
These GDSTIME fans are usually used for servers, desktops, or mining farms and supposedly only use 11 watts of power and supposedly move 93 cubic feet per minute per fan at 35db – so 372 cfm total.
From my experience it runs at around 43db from about 5 feet away.
It also has variable speed instead of just high, medium, and low, so it could probably move 300 cfm at around 80% of power and be much, much quieter.
Putting this all together took about 40 minutes.
It’s a 5 sided filter CR box that sits 6 inches above the ground with the fan pointing up (filter direction obviously facing in).
The key is the little clips that come with the fans to clip to…other fans.
Instead of doing that I used them as a lip on two sides, so the fan isn’t actually taped to the filters, meaning I can remove it when needed. It rests perfectly in the middle of the four filters, which are basically the sides.
It’s not a perfect seal and I’ll probably make some sort of shroud for the top, but the rest of it is air tight.
If you compare this with a Coway Airmega ap-1512hh this moves about 120 cfm more.
It’s certainly not as attractive, but it also uses a lot energy, and I got the experience of making it myself.
These fans are rated for 50k hours so…about 6 years.
So the 4 sides and the bottom has a total of 500 square inches of surface area, is quieter than a box fan, runs on basically 1/7th the energy, doesn’t look awful, and can be put in much smaller spaces (like a desk) than a CR with a 20 inch box fan.
The other key is not staggering the filters (the sides) and using the 1 inch dowls at the corner supports instead.
It all fits together really well.

The 3 fan version works perfectly to help our RV refrigerator cool down quicker and stay cool in very hot temps. I love the speed controller. I am imagining that if we camp in very cold weather, I might need to slow down or turn off the fans as the fridge won’t need the extra help. Seems well built, is easy to work with, and is a great value at $40.
