Strapped 4 together on an open window to cool my workshop. Blowing inward worked best. Took feet off and tye wrapped together. On low setting very quiet and nice gentle breeze. Would have preferred white fans but this was quick solution

Excellent piece of kit, all parts supplied to modify to own needs. Even support feet with rubber covers for free standing vibration. Variable speed is most helpful.

Used to make a council Air con unit, works great, plenty of power

So far, so good. I'm using my fan for a more unconventional purpose, as a component in my custom built humidifier, which supplies mist and fresh air to my gourmet mushroom fruiting chamber. The speed control function is really important for dialling in the correct amount of humidity and air circulation, and for this purpose the fan is working perfectly. My fan is automatically switched on for a minute or two every 10 minutes via a hygrometer, so I can't comment on how it performs during continuous function, but in terms of controllability it's fantastic. The fan gets a little noisy when it's cranked up to maximum but this isn't an issue for me as the speed is set at around 20%. At this level it's barely noticeable. It's a fan...... they get noisy when they run at speed so no star deducted for this. Think aeroplane propeller! The speed control unit is nice and compact and has mounting fixtures to attach it to a wall, desk, component board etc. You'll need to supply your own screws/wall plugs if you decide to use this feature. All in all, it's a nice little product. Hopefully it will have some decent longevity.

Works well

Amazing fans, like pc fans they are extremely strong, I don't use that much as really clears the humidity but give a huge amount of airflow into all tank corners so no mold growth

I used it frequently and the dial on the fan speed controller her broke. The bite point of where it turns on/off has broke, and I can not longer use it. I am trying to find a replacement, but not had much luck.

Ho acquistato questo prodotto per piazzarlo sotto un router “Fritz”. Costruito con criterio e buon materiale, fa bene il suo lavoro. Un unico neo: se lo si tiene ad un regime elevato di rotazione delle 4 ventole, almeno per me, risulta un po’ troppo rumoroso…ma le ventole si possono regolare, per fortuna. La 5^ stella non l’ho attribuita proprio per quest’ultimo “difetto”.

stopped working after a week. it was running overall about 100 hours max.
