Review on O2COOL 5-inch Portable USB or Electric Fan in Black and Gray by Jeffrey Crutcher

I bought the same fan over a year ago and it has become my workhorse to cool my laptop CPU and GPU. When my computer was under heavy load, it would overheat and shut down several times a day. Under idle conditions, the GPU ran hotter than was assumed for sure (>60 degrees C). When stress testing a graphics card (GPU) in the middle of the test, the temperature of the GPU rises sharply until it exceeds 100 degrees C (212 degrees Fahrenheit), after which the computer shuts down to prevent the GPU from catching fire. Wanting to avoid heat damage to my laptop components, I purchased a vented adjustable laptop stand from RevainBasics to improve airflow and raised the stand to a 40 degree angle (which gives a great typing angle for the keyboard and the screen to eye level). all this improves posture and relieves neck and back tension), placed this fan behind the laptop, plugged the fan into the USB port and turned on the fan. Now when I turn on the laptop, the fan turns on and cools the bottom of the laptop during use. Turning off the laptop also turns off the fan. This has helped keep my laptop's GPU and CPU temperatures below 60 degrees Celsius most of the time, which I think will extend their lifespan. In addition, this fan is lightweight, folds compactly and rests on itself. The five-blade fan with unique blade design ensures fast airflow with minimal fan noise. The included cable connects to the fan with an adapter similar to a regular audio jack; The other end plugs into a USB port or a power adapter that plugs into the wall outlet to use AC power to power the fan. There are only two things I would change about this fan: Currently it is only a single speed fan. I would like a stepless switch so you can dial in the exact fan speed you want for any occasion. The second thing I would change is the audio jack connector to connect the cable to the fan; If it had a mini or micro USB port instead of an audio jack, it would be easier to swap out the cable if needed.
