Review on 🖥️ upHere 120mm Silent Red LED Case Fan 3-Pack with PWM Technology for Computer Cases, CPU Coolers, Radiators - Ultra Quiet, Premium Edition, 4-Pin Connections (R12CM4-3) by Robert Weeks

Awesome fans if you want your PC to look and work great. side of the fan, so no matter how you mount it, you get a beautiful glow from any direction. They run off a single 4-pin PWM fan header and can be powered from a single two-way splitter up to around 50% fan speed. Before the LEDs start flashing due to a power failure (from splitting into 2 fans), 3 fans will do so at 70%, no percentage will be given for a single fan, so an active splitter or fan hub is recommended, or use them on their run their own connections on the motherboard. We have a total of 6 fans in a 9 fan system, 3 inlets running at 80% on a single unpowered 3-way splitter, one as a rear outlet at around 40% and two on the main cooler with a dual 120mm tower Cooler runs curved depending on CPU temp and the other 3 (Cougar brand) fans go up to around 40% and everything stays nice and cool even on i7 6700k at 4.5Ghz with Windforce r9. Not to mention that the number of fans allows me to run slower and still produce great airflow, resulting in quieter operation.
