    • Awesome!!!
Size: 3x 120mm fan
UPDATED 4/30/25 ~~~~~~~~~~~~~~~ I've been using this cooling fan array set for almost 11 months, every day... It still performs flawlessly. During Phoenix Summers I do tend to have the fan on higher speed which does raise the fan "noise" but to be honest, once a I start playing anything on my media center, it is not even slightly perceptible. and I'm sitting only 10ft away. Even so it's barely audible when there's silence in the room. The biggest value of this fan array is its ability to reduce the temperature of the multiple USB drive enclosures I purchased it for to help keep the drives running cool, which in turn is providing a longer life span for the drives. Since using this set, I've not had any drive failures. For those wondering, I know the temperature of each drive because I bought multiple External USB enclosures from Amazon each of which has a small display unit in them showing actual drive temperature. The actual drive temperatures (small heat sensor is physically attached to the drive within each enclosure) never get more than about 7F above room temperature even when running/operating all day. Sorry, those enclosures are no longer available (very sad because I'd have purchased more than the 4 I already have if I could). There are others you can find but I've not found any that have the display unit in the face of the enclosure like the ones I have. I'm still very pleased with this purchase and am still using the fan array per the REVIEW UPDATE I posted previously below. I did make one minor improvement, I removed the front grill, spray painted it matt black and reattached it as the chrome finish was visible. Now it blends in so well, you can't tell the fan array is there unless/until you open the door. The rubber feet I added to the unit also helped to reduce a small amount of the "noise". So now all I hear is the noise of the air flow. Anyone who has a ceiling or floor fan knows that even if you have a "silent" fan, you can still hear the noise of the air flow when fans are on high. As this array has a variable speed control it's easy to dial in a reduced speed which makes it almost silent but still very effective. 11 months on, I still highly recommend the array even though I have added some minor modifications for my own personal setup. ORIGINAL UPDATE ~~~~~~~~~~~~~~~ I tried a different vendors fan array which used 5v fans but due to cable lengths, not working with USB extensions leads and low CFM rating... I returned that unit and purchased this one instead. WHAT A DIFFERENCE!!!! It's not simply that this one works.... it's because this one REALLY works... I'm using this for my Entertainment Center/Home Theater. 1. With the variable switch that is provided (Off and then rotate on to supply 4V thru 12V to the 3 x fan array) you can dial in the amount of cooling and find the sweet spot on the "noise" that you are willing to live with. 2. On full (12V) there is now noticeable noise of the fan/air flow but it's not anywhere near as loud as I expected based on Reviews (and I'm not deaf!!!). In a totally quiet environment, it would/could be off putting that's not in question. The airflow on full is very significant. I personally wouldn't run it on 12V high all the time due to the detectable whine/noise, unless I move the fans to the back of the Entertainment center which might mask the sound completely else I'll turn it down slightly. Might play with that in the next couple of days. 3. Dialed in to a lower voltage, it can be run down to a speed where it still moves air but is silent. It still moves more air than the 5V fans I tried and returned. (How can he say that... Cos I have a wind gauge...) 4. My need was for external drives in separate Enclosures which sit on a separate shelf in the Unit. They get hot so I tend to leave a small door open in front of them when running the media center. I never had a problem until recently when a drive "appeared" to go bad. Turned out it wasn't the drive, it was either the Drive enclosure or it's PSU. However, I felt the issue may have been aggravated by heat hence this purchase Fans come with some nice rubber feet and extra long screws bolts and nuts if required, or it also comes with 4 felt stick on pads so you can choose yourself. I really like this unit, it has decreased the temperature of my drives by about 10% (was in the high 90's to start with). The variable speed and 12V fans makes this unit a really great cooling device. I'd definitely recommend it. Only shame is that the 4 fan unit is so much more expensive than the 3 but the 3 easily delivers in a Home Theater/Entertainment Center environment. UPDATE: ======= Hate to be the bearer of bad news. Fans are still working great but... I tried mounting them into the door of the Entertainment center. The "whine" was really irritating even on the lowest voltage setting.... I removed the fans from the door and remounted them used silicone rubber mounting pads between the fans and the door... Still the same problem. For now I've got them standing free standing on the inside edge of the cabinet. I can up the voltage and they're running about 50% speed with barely a noise. I can turn the fan speed up and eventually at full 12 volts there is a discernible noise. The air flow at 12V though is so powerful, the fans are almost pushing themselves in the opposite direction which is good. I'm definitely keeping the fans, they DO the job I need them to perfectly and I'll experiment with mounting them and see if I can find a solution for my specific environment. I'll post an update if I find a solution to the "whine" but for cooling, they most certainly do the job very well. Even with a slight noise, I still love the array and their functionality to keep the inside of the cabinet much cooler than without. Oh and I can now have the cabinet door shut and it's still keeping my hard drives cool. ... show more

    • Works great as an exhaust!

These are great, exactly what I was looking for - the airflow is what I was hoping for and the build quality is solid. I am wanting to build this out into a x8 rack to fill my entire window base (so the house doesn't smell like pot when I game haha). I am currently working with GDSTime to find out options for the power controller (i.e. my 40 inch window will fit two x4 units with a little extra filler, so I'd like to try and run them off of one power controller to keep things convenient and overall at a lower speed then x4 only. I'll keep you all posted! In terms of value, these reminder me of the fans from the AntMiners - they are very well built and are remarkably well priced for this level of build quality. They are rated to last pretty much forever for me lol (I won't run these more than a few minutes at a time), so I don't expect I'd worry about them ever failing. Oh yes, this is a solid x4 rack. With the right power extension I can place this anywhere (e.g. by the side door) to vent the home. You could also take this camping and plug the DC into your battery - would absolutely vent a tent out on lowest quiet setting. ... show more

    • Moves lots of air, quiet, and fair price
Size: 3x 120mm fan
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. ... show more

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. ... show more

    • A Good Fan for a Small Corsi-Rosenthal Box - Quiet, Low Power Usage, and Good CFM
Size: 4x 120mm fan
Review Image by monopod man
Review Image by monopod man
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 2x2 or a 1x4 configuration - I went with 2x2, 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 less 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. ... show more

    • Defective speed controller throwing sparks
Size: 4x 120mm fan
When it arrived, the box was in pristine condition, the fans looked perfect. I hooked up all the cords and plugged it in. It worked! For five seconds. As soon as I touched the speed controller it stopped. It never started again. So, I fiddled with it. By turning the knob on the speed controller back and forth very quickly I could sometimes get the light to turn on… for one second. I opened the speed controller up and tried that again, and I could see the inside part of the knob spark when I got the light to turn on. So, clearly the speed controller is defective. I called Amazon customer service (the seller’s recommendation), and apparently to get a refund or replacement you have to mail the defective product back. Nope. I don’t have time in my day to figure out where and how to do that. I have NEVER bought anything from Amazon that required mailing a defective item back in order to get a refund or replacement, not in 10+ years. It strikes me as very suspicious. In light of the sparks I got when I tried to use the product normally, I would strongly recommend anyone to NOT BUY THIS PRODUCT, or it may end up burning your house down. ... show more

    • Works exactly as we'd hoped.
Size: 4x 120mm fan
We use it to gently move air across a baseboard heater that doesn't adequately heat the whole room when it is particularly cold and/or windy outside. It moves plenty of air for our purposes and isn't unduly loud for what it is doing. We run it full tilt when the heat first comes on, then turn it down as the room heats up. Has made this room much more comfortable in easy weather. ... show more
