💨 Coolerguys Dual 80mm USB Cooling Fans: Beat the Heat with Double the Cooling Power! Review

I bought this set to go on a motorcycle tour during the hottest weeks of this summer. I wore Gore-Tex boots because I knew it was going to rain on the way. Unfortunately, Gore-Tex can get sticky on hot and humid days. Luckily this set of fans did wonders to dry the inside of my boots. Every night before bed, I put fans in the holes in my boots, which are powered by a spare phone charger (with a USB port, of course). Fresh air blew gently through the boots, and in the morning they were dry - and

I needed a small fan to keep my ASUS laptop cool as I use it as a TV guide server. I've attached two shots showing the current drawn from two different USB power supplies. The third shot is my temporary setup and the aluminum case is in development. I had to test the design first before final version. Current draw is just over the spec of 50mA (0.050A), which is remarkable considering how these fans BUBBLE. They lowered my laptop's temperature by 2-4°C, which isn't much, but every degree counts

Ideal for closet ventilation. I have a processor in the closet. I left a large gap in the front of the case and an exhaust vent next to the case fan, hoping this would be enough to keep my CPU cool, but the case temp was always around 110. I bought it, flipped the grill over and installed them. both in such a way that they draw hot air from the top of the cabinet. I closed the drilled holes for the cables in such a way that cold air only enters through a slit in the front of the housing. It…

I use them to cool my wireless router. You are absolutely perfect for the job. The router is a cylindrical DLink DIR760L. The fans match the router very well. I lay the router on its side and use the fans to push air in from one end and pull it out the other. The CPU temperature dropped by more than 20 degrees Celsius. Noise is negligible. The main consideration was that the fans should be USB powered. The router has a USB port, so I don't need an external power supply. I will buy a few more of

This is an amazing set of fans. I was very impressed with the quality and noise level. Very quiet. I glued two fans together to make a block. I then removed the top two corner screws and replaced them with a screw about 29mm long. The actual width is 25mm, which allows me to thread longer screws directly into the small vents on the side of the receiver. As soon as I plugged the USB power cord into the front of my receiver, it immediately started cooling my component. I read just before…

I bought this product for use in my entertainment center as I just bought a surround sound system which generates quite a bit of heat. Below are the pros and cons of the product: Pros: Incredibly easy to set up and use. The fans came pre-assembled, all I had to do was hook them up to my surround sound system and they worked. Very quiet. These fans are so quiet, you won't know they're on unless you see the blades moving. An extremely big plus, I think. - Cools my system. This is really important
