Negative Positive
Title: Works fine for my purpose
Review: Use these for cooling down my audio receiver and power amp. I am hoping that by using the fan, I can at least avoid heat issue and possible prolong the life of the receiver.About the fan itself, I only use it at less than half of the power. Else, I could hear the fan. However, using less than half power, it is sufficient to keep the receiver from getting too hot. So far only warm to touch or cold to touch, depending on the sound level.One fan is plugged to the TV's usb port and it will turn on the fan on the receiver each time I turn on the TV and use the receiver to play the digital audio via HDMI ARC feature.The other fan is plugged to the Blu-ray player so that each time I use it for playing music loud, it would cool down my Emotiva power amp.I am also glad that the cable itself is long enough to span 2+ feet.Although this fan works fine, I am taking one star away since anything more than 50% power causes noticeable noise in my setup.
Is the review positive or negative?
