I purchased this unit to cool my Mac Mini while editing video. The build quality, though plastic, is quite sturdy. The fans seem to be spinning at the same speed and have a slight white-noise whir about them. As for performance, even under heavy rendering and using an E-GPU, everything is a lot cooler than without. Highly recommend.

I first bought these for my camera dvr as it got really warm to the touch. I simply put it atop the dvr and it's amazing how cool it runs now. Since I have purchased 2 more, one for my xbox and one for my tv command center and WOW, what a difference. They are very quiet and make a huge difference in operating temperature on my devices. Yep, I would recommend.

Just got it and seems to do what I expected, put it under my PlayStation 4 and plugged it into the usb so it will only be on when the system is on hopefully it will last longer than others I have tried.

I like it works great but is alittle noise

Love the cooling and quietness of the fans… however one of the fans are already buzzing and it’s now to noisy to use…
