Review on UpHere 120Mm Blue Case Fan LED Silent Fan For Computer Cases by Johnny Spencer

Great fans when you want your PC to be beautiful and perform well. Regardless of the mounting, you get a beautiful glow from every direction. They run off a single 4-pin PWM fan header and can run from a single two-way splitter up to around 50% fan speed before the LEDs start flickering. Due to power loss (due to 2 fan splitting), 3 fans account for 70%, didn't get a percentage for a fan, so it is recommended to use an active splitter or fan hub, or power them from their own headers on the motherboard. We have 6 total in a system of 9 fans, 3 air intakes run at around 80% on a single unpowered 3-way splitter, one as a rear exhaust at around 40% and two on the main dual radiator. The 120mm tower cooler curves with CPU temperature and the remaining 3 fans (cougar brand) run about 40% higher and everything stays nice and cool even on i7 6700k at 4.5GHz with r9 wind force. Not to mention that the number of fans allows me to run slower and still produce great airflow, resulting in quieter operation.
