4 x 120mm Computer Fan with AC 220V 230V 240V Powered UK Plug 4V-12V Speed Controller Dual Ball Big Airflow 120mm x 25mm Server Rack Cooling Fan For Laptop Workstation Ventilation

Bought this to aid cooling on my home miner. Powerful, quiet and have worked flawlessly for a month of constant use so far. Edit: 4 months after purchase and being on constantly and still working flawlessly. Edit: Over a year after purchase and constant use both fans work like the day I bought them. Good quality reliable fans.

So yes the UK plug is not of the "correct" type, but at the end of the day the performance of this as a package makes up for it..... The power supply work great and is matched up well with the fan, you can have low flow silent operation or full power with noise. Air flow at full power is comparible to the original orange blade thermaltake fans, but at a fraction of the price. If the plug really bothers you then change it (I won't be - electrical and tech tinkerer of 15 years), its double insulated and is of all plastic construction at the end of the day... Would recommend.

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

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.

Came on time in good working order

I got this and used it with a 3d printed desktop fan designed by Noctua its cheaper than using a proper Notua fan and works well .

Fast delivery via amazon Prime, This fan is quite powerful for the size, the speed control unit is a very useful addition, works very well and so far has been been reliable.

Great little fan. Runs pretty much silent at lower speeds. There is a little noise at higher speeds but most of it is due to the blades rather than the motor. It moves a lot of air too. Used it as an air mover in the top of a radiator cover to push more heat into a room. It did the job brilliantly. The long lead it comes with is a real bonus too.

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.
