Despite their size, USB fans can be powerful, and most offer different speed settings. They won’t cool down an entire room, but they can keep you comfortable when used at a close distance, such as an office desk or bedside table. Best of all, they are inexpensive.
Do USB fans use less electricity?
The 5-V little toy fans are just toys. Second, to get the USB port power, personal computers use AC-DC power supplies, ATX12V style or similar. They usually operate at 30% of max load, and efficiency is about 80% in that mode. So the conversion into USB power is only 80% efficient as compared to wall outlet.
Are USB fans safe for PC?

How hot is too hot for GPU?
In order to enjoy maximum performance from your GPU, keep the temperature below 80C. A GPU’s temperature can reach a high of 180C faster than a CPU’s, which should keep it below 60.
