What am I losing if I do this? I have a great CPU cooler, but the fan cable it has needs 5 holes. Nevertheless, I was able to get it to turn on by plugging it into my mobo's 4-pin CPU fan header, but do I lose speed control or something; I thought that's what the fourth wire in a 4-pin connector was for all along. Is it a temperature read? Thanks in advance if anyone knows the answer; I wasn't able to find it by Googling.
