Review on 🌀 High Performance GDSTIME Dual 120mm 5V USB Fans: Ultimate Cooling Solution for Routers, TV Boxes, Micro Computers, and Electronics by Peter Nobles

I have 2 routers and bought 2 of them. While they actually work quite well (when they do), they tend to develop noisy "camps". This is not good. This is a quality control issue and indicates that one of the fans is about to fail. Months, weeks, who knows. Of the 2 I bought, 1 had noisy bearings from the original purchase. I sent it back for a replacement. With the second, after about 3 weeks, the bearings in one of the fans rustled. I replace it too. This is NOT a good track record. If they didn't have such a big quality issue I would happily give 5 stars. Due to quality and replacement issues, I can only give him 2 at the moment.
