I'm setting up a build with a mATX motherboard that has just two 4-pin fan connectors and one CPU fan connector. I need to run eight fans, all 120 mm, inside an inwin 303 case (three at the top, three at the bottom, one exhaust for the back and one for the CPU). To manage this, I'm considering a 1-to-4 fan splitter. Since the strongest fan draws about 0.24A, putting four of them into one connector would draw roughly 0.96A, which is close to the 1Amp limit. So would this cause my motherboard to overheat or at least reduce fan speeds?

Ps. I'm using:
-3 thermaltake with 12 Red LED fans
-4 Arctic F12 PWM PST fans
-Cryorig H7 for CPU cooler
PSU power is over 500 Watts

A specialized power hub is needed to handle the high current draw of these fans. This hub will free the motherboard's maximum 1A header from fan power, using the PSU's SATA/Molex connections to supply fans directly through the hub while keeping speed control and monitoring intact (the hub remains linked to the motherboard's 4-pin connector).
