Hey, I'm planning on getting a Hyper 212+ (Not from Newegg, their price is much more expensive) and I'm using a CM R4 as the second fan to do a push/pull setup. Is it safe to use a 4 pin y splitter on the CPU FAN socket to power both? Or should I plug the 2nd fan into a 4 pin fan socket on the motherboard on the opposite end (Would it still work with CPU temperature PWM?)
