Silencioso.

Öncesinde araştırdım, tek fan ses açısından çok iyi. En yüksek hızda bile sesi çok az. Soğutma derseniz tam soğutma diyemem; daha çok hava sirkülasyonunu hızlandırma gibi bir rol üstleniyor. Nispeten bir soğuma var ama sıcaklıkta biraz azalma gibi diyebilirim, öyle bilgisayar kapalıymış gibi bir serinlik beklemeyin. Dokunulmayacak kadar ısınan bölgeler dokunulabilir oluyor gibi.

Seems to reduce the temperature of my 13" MBP by 5-10 degrees. The 20" fan is quite quiet, though as its a hot summer I got a Dyson desk fan blowing in my direction that drowns out any other noise. But not expecting the noise to be a problem later in the year. LED obviously pointless for my use. But can be switched off. The cooler does need to be manually turned off as the MBP seems to still supply it with power even when it sleeps and the MBP power is turned off. Note the USB pass through has a knobly bit on its right hand side for where the cable comes out, it fits fine on my 2014 13" MBP's right hand side USB port as its at the back, but can't be used on the left hand side as it would obstruct my headphones socket. Happy camper so far.

I’ve used this fan for a while now, and i really like it. Its large, pretty quiet, and it moves a good hit of air through it. I keep it on when my laptop is on at all times and it really keeps my temps down. I highly recommend this to anyone with a laptop to improve the lifespan on it.

It's truly incredible how quiet it is and how much it actually helps with keeping your computer from overheating. However the reason I'd rate it 6/10 is because of the quality of the product. the cable is extremely cheaply made, the plastics itself on the entire product feel really cheap and it just doesn't feel like a premium product that you're paying for.Functionality wise, it's one of the best laptop coolers out there but quality wise, there's a ton of better options.
