I currently have a Hyper 212 evo cooling my FX-6300. I want to add another fan for a push pull setup but I would have to connect that fan with a 4-pin molex connector (because there is obviously only one CPU_FAN header on my motherboard. If I did that wouldnt the RPM's be different? Is there some sort of CPU fan Y splitter-cable or something I would have to buy? Also which fans would you suggest I get for this setup?
