Wathai 140mm x 25mm Computer Fan with AC Plug 110V 120V 220V 240V Variable Speed Controller for DIY Biltong Box Reptile Aquarium Receiver DVR PlayStation Xbox Cabinet Ventilation Cooling

I have a vintage Technics SA-818 receiver from 1981. It's in Mint condition. It's been in a stereo cabinet for many years, and it gets warm,and if left on for an hour or more, hot. I recently decided to install a AC Infinity AC-ACT10 fan ventilation system, for $129.00 . Yes, this was am expensive cooling system, but, with its build and features, I felt it was well worth it. I got the ACT -10 on Monday, and installed it immediately. When I powered the unit up, it ran Great..! However, the EMI/ RF it created,shut off ALL reception to the FM tuner..! I contacted customer service, at AC- Infinity and they suggested a ferrite core bead, on the AC power line would eliminate the noise....WRONG.!It did nothing..! I returned the unit, the next day, but was still needing cooling for my receiver.I looked at this fan, and read many reviews, from others saying this fan worked excellently with their receivers. I thought for $14 I couldn't go wrong. I installed it as soon as it came today, and tried it with my receiver. The fan on the lowest setting, moves tons of air..! And, absolutely no noise on the FM tuner side..!! Sometimes, cheaper IS better..!! I highly recommend this product..!!!

Great fan! I bought it for cooling my GMRS radio amplifier. It works perfectly. Not even very loud on high, a little bit but not bad. Reall nice and quiet on a low setting though. Seems good enough for me!

This fan is very well made, easy to install, and works great to keep my entertainment center cool.

Very powerful for it's size fully adjustable good fan to keep appliances cool

These may seem expensive for ONE FAN at $14 - $20, but they aren't since most PC CASE fans don't meet this rated speed, don't have waterproofing, and don't come with the controller. My REATAN PC is all metal, and uses that fact to its advantage. The REATAN also has a fan on its underside to cool the RAM and M.2s.I use the 140 on the bottom to assist the bottom fan and suck heat from it. Then on top bought 3 40x120 heatsinks (going to replace it with a 120x120 that just came in) and used a 120MM WATHAI fan on top to assist with top cooling. Since the CPU heat spreader touches the metal top of this PC CASE. Keeps my CPU and GPU in the mid 40s.These things move AIR, you put your hand on the intake side, and it sucks your hand in, yay safety grills. Also these are REASONABLY PRICED, as someone who did try to jerry rig his own solution. Similar CFM rated fans cost about $15 minimum and top out at usually 1800RPMs. That's just the fan, add a filter, that's about $6 for 1 or can get a 3 pack for $12, then you need feet, $5 for 20, then the adapter to wall which is $5, then you need screws for the feet which are about $3, then you might want to control the fan speed so need a $20 piece that seems to only be made by NOCTUA. And there you go, when all is said and done, your homemade equivalent now cost you 3x as much. Especially if you want the same IP67 rating these offer.They're built well, move a crap ton of air, aren't loud, and are the complete package. ONLY ADDITIONAL PURCHASE I'd make, is a "Y" splitter that way you only need one controller for both fans in my setup, and is only taking one outlet space. That's probably the ONLY COMPLAINT I have, the control box is unnecessarily MASSIVE. Especially when used in the usecases they're describing. The noctua controller and CoolerGuy 12v to fan adapter is such a tiny package, you could easily VHB mount it to the front of your router, DVR, etc device.100% recommend.

I originally bought the 120 mm dual fans from same seller but those didn’t have the power I thought they would. I need a certain amount of air flow for a refrigeration evap coil. So I ordered a pair of the 140mm ones and wow! night and day for being so close in size. A single 140mm fan has the same power in wattage as the combined dual 120’s and feels so much stronger. So I get a true 12 watts of power with a pair of the 140’s. The blades are bigger and the motor inside is noticeably larger as well. Just what I needed. The turntable knob for fan speed is a really nice feature. i have to use them on full blast all the time so hopefully they stand the test of time. Really good product five stars

So far so good. I am used it for my of GE Side By Side Refrigerator compressor esternal cooling system. I took of the cover assess and replace my bigger fan with this small one and its working like a charm. Keeping my finger crossed, I bought another one to turn off one and turn on the other one every two days. You cannot get good service these days and the new fridge are too big in depth for my kitchen door.

I have this set up in front of a mist fogger to circulate the humidity in a grow tent for mycology experiments and growing cactus and vegetables. I have the fan and the fogger connected to an Inkbird humidity controller. Bam. There it is, it completes the system. The noise is barely noticeable outside the tent, but of course if you set it on high speed it makes a bit more noise. But overall I am happy with how quiet it is, and the fan speed controller is fantastic also. I also love that the fan and controller connect with a plug, so if either of them go bad, you can easily replace with no wiring necessary. 2 months so far and still working great. That's what you needed to know, right? Happy growing! Helpful?
