Wathai 80mm Small Computer Cooling Fan with AC Plug, 110V 120V 220V 240V Fan Enhanced Cooling Solution for Electronic Components, PC Cases, Greenhouses, Terrariums, and Modem Cool Projects

I placed this fan on it's little legs - (MISSING TWO NUTS for screwing the legs on, BTW!) - under an old power amp that's been overheating. It really works! Cools things down just great and I can't hardly hear it at all. I would buy another for sure.

Sometimes the quality and purpose of design belie the price paid. This is one of those items. Works precisely as described and solved a long standing problem better than the last fan with separately purchased variable power supply. Smooth gradations for the easy adjustment of fan speed/noise and pulls very little current for 24/7 use applications.

This is exactly what I needed. Plugs in a wall outlet and has a variable speed fan. Can be ultra quiet at very low speed settings. Turned up all the way it can provide a good amount of air flow. The noise level goes up but it isn't overpowering. I set it on top of my (tube) radio and I run it just above the lowest setting. Keeps the radio much cooler. I am very happy with this product. The price was so reasonable I didn't have to take the time to manufacture something myself. When I saw the product I immediately bought two (2) of them. I'm glad I did. If you need a variable speed fan you will be happy with this item.

I initially liked this product and used it under my router, which kept the device cool. I was impressed enough to order a dust shield and another unit for my modem. However, I've now downgraded my rating to 4 stars due to some issues: the bearing produces noise, and the wire is not securely attached to the fan, causing it to hang loose. I had to use hot glue to secure it properly. Consequently, I plan to purchase a fluid dynamic bearing fan instead, as they are almost silent at night and have greater longevity.

I love the variable control unit, and at full power it moves a ton of air. I used it to cool down my hotroasted coffee beans, and in 2 minutes they are cold. Happy Happy! Very reasonable low sound on full.

I have a schist Aegir Class A stereo power amp in a cabinet, it runs hot, placed this small fan on top to ventilate heat out the back of the cabinet, works great, no issues.

Looks and works great. I am using it inside my Guitar Tube Amplifier.

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?

Ce quitte de ventilateur avec contrôleur. Fonctionne très bien, très puissant.

Parfait, bien emballé, beau produit, souffle vraiment bien, relativement silencieux. Très content de mon achat. Le variateur d'intensité fait très bien le travail.

Removed from packaging to test it, works as it should. Haven’t completed the project yet to put it to full use.

I bought this to make a biltong dryer. It did it’s job. There are lots of computer fans available but in order for them to be useable you needed to buy additional parts and then put them together. This one was already configured, with a “dimmer”/speed control.

as described bought this to move air from my propane wall heater and it does the trick just nicely
