Review on 💨 75mm USB Fan by GDSTIME - Powerful 75mm x 15mm Blower Fan for Efficient Cooling, 5V DC Brushless Cooling Fan by Paul Green

I bought two of these for the inside of my Mando helmet that I wear when airsoft. The fans were a good size and a bit noisy because they were inside my helmet and the sounds reverberated but weren't loud enough to affect my mic and amp which were in my helmet to project my voice . Unfortunately my cables got disconnected but I think it was because I took my helmet off. I eat 5 stars because the sound was low and thin and blew very well with both fans running. Worked well even with just 1 puff. I will be ordering more to ensure a more secure fit in my helmet so the cables don't come loose.
