GDSTIME75mm USB Fan, 75mm x 15mm Blower Fan, 5V DC Brushless Cooling Fan For Laptop

Works very well to vent a single slot card

Powerful little fan! I didn't need it for a computer or 3D printer. I have used these to make kegerator tower cooler fans, and they work perfect if you use them correctly. I actually used one most recently to keep cool while sleeping when the power was out. Hooked it up to my power bank and it kept me cool all night! I could think of a thousand uses for these little fans. Great product, and quiet for the amount of air it puts out.

I did a DIY conversion to turn and old nonfunctional iMac into a monitor. There are conversion kits that let you use the video screen and connect it to a desktop or laptop computer. However when I got it all finished and hooked up to my desktop, I was running into problems with heat management and I needed a thin fan to direct air through the small opening in the back of the monitor case to cool things down.This fan fits the bill quite well. It was a little smaller than expected, but the airflow is very good even with its small size. Once it got installed the overheating problems have improved significantly.The only down side is the fan noise. If you use it in a quiet room you will hear this fan. It comes in at about 50 to 55 dB, so be aware it might be loud enough to bother some people.

Comes with a USB cable that has 3 power settings. Good deal. Quality.

The fan works, moves a satisfactory amount of air, and makes a modest amount of noise. It is slightly unbalanced, but it should not be an issue for most applications. I was disappointed that the speed control was missing, even though it is pictures and listed in the description.

My older but still functional HP Laptop was getting super hot. I elevated it to allow for better airflow to no avail. I saw this item and said how can I go wrong? Im glad I bought, it works like a dream. Eliminated the heating problem. I bought the smallest version and it works perfectfly. Fan has 3 control speeds and plugs into a USB port. Good deal. Let's see how it works out in the long run.

This 75mm x 15mm fan came with the three-speed switch built into the usb cable. The fan blows like it should. The breeze makes sound coming out even at the lowest level - not noise, but sound.

I removed the speed switch from the line and the fan defaults to its high speed setting when powered. I did this because I need the fan to restart after power failures. With the speed switch, you have to manually turn the fan on again after power is restored.
