Default Need some help with a PWM splitter calculation

So i purchased 2 LL140s and a LL120 and now all thats left is to buy either a fan hub or a pwm splitter.

The one thats on my mind is Noctua NA-SYC1

My actual question is : Will 1 splitter be able to handle the power draw of those 2 fans?

Thanks in return :)

The splitter wire is rarely the limitation and that one is a reputable product. I have used them for several years. The fan controller providing the power to the fans is more likely to be the limiting factor. Most motherboard headers are 1.0A. The LLs are 0.30A each, so two on one header is not a problem. If you are planning to connect them to something else, make sure you find out the current limit for that specific device, but it would be shocking to find anything less than 1.0A.
