Cooling pad does well its job. I attached one pic with a few tests concerning coller efficacy on CPU temp. 1. CPU temp. without cooler (after about 2 hours standard pc using: few pages of internet, office), 2. CPU temp after 6min of working cooler in the same point 1. condition, 3. CPU temp. after 31min of working cooler (same point 1 condition), 4. CPU temp after 10min in game that uses a lot of CPU resources, 5. CPU temp after 5 min off game, 6. CPU temp. after 18min off game. So in no game condition after 30min of working, the cooler decreases temp of about 10 degrees C. It takes about 18min to cool down the temp of about 15 degrees C after playing for 10min to return to point 3. CPU temp. Fans make some noise but it`s acceptable. The usb cable could have been a little bit longer. It`s pitty there is no on/off button. The build is very light and cooler seems fragile but overall the ratio of price/quality is ok.

Works fine. Wouldn't mind if quieter but NOT noisy per se. Just hear it easily in very quiet home office. Wpuld give 5 stars if suoer quiet

works well but a bit cumbersome. Im using it with my 15" laptop but it fits the smaller ones better.

in my review I meant laptop, not PC of course

Keeps my MacBook cool in closed mode when I’m on an external display.

This cooling fan works very well,
