I recently purchased an Enermax ETS-T40 CPU cooler that comes with a single PWM fan. I also purchased a second PWM fan to use with the cooler as the CPU cooler comes with the hardware to mount a second fan. The problem I'm having is how to power the second PWM fan when there is only one connector on the motherboard for a CPU fan. Is there a way to splice the PWM leads together so that both fans operate at the same speed or would that draw too much power from the motherboard connector for the CPU fan? The other option I'm looking at is a fan controller. I'm building this computer for my wife as a budget friendly gaming PC so if I can avoid using a fan controller, I'd like to. Thanks in advance for any advice.

There is a SPLITTER for that.

Also, your Amperage from the motherboard should be sufficient, but verify that in the manual. For example, if it supplied 1Amp (1000mA) to the CPU_FAN socket and each fan uses a max of 500mA you're fine.

(I forget the typical values)
