Review on Enhance Performance & Prevent Overheating with 2PACK 80mm USB Cooling Fan for AV Receiver DVR Playstation/TV Box/Game Console by Tyrell Christmas

Function: Airflow volume is pretty strong for its size. I didn't check the temperature, but I had a feeling my Onkyo receiver was running at a much lower temperature. Really nice rubber to reduce vibration does the trick. Controls: LED light and speed controls are very useful. Especially in a dark little office. It's USB powered, so I just plugged it into the Onkyo's USB port. It should work well with the USB phone charger adapter. Quality: Fan, controller and rubber feet are made of good materials. He worked 24/7 in my small stereo office and met my expectations 100%. Nice and quiet too.
