    Be careful when you use the word HUB. That implies that it is a external USB hub but your text implies that it's the USB ports on your computer. Is that correct?

    Fans draw more power than a mouse. Don't know why you are powering a fan from a USB port. Looks like that port is not supplying enough power for a fan.

    No, it can be the laptop. As you do work with it the CPU, internal fans, drives and GPU draw various amounts of power. This can then vary the amount of available power to the USB. If you are going to run a high draw item get a powered hub to run it off of.

    Do not just depend on a larger power brick as the laptops CAPs may not be able to handle it.
