Hi, so i made a computer from scratch a few months ago, its got a 200mm fan, 3x 120mm fan and another 120mm fan on the heatsink. The motherboard only has 2, 3 pin, slots to control fan speed. One of these is for the CPU fan and the other just has the 200mm fan plugged into it, this means that the other 3, 120mm fans are running at full blast because they had to get connected directly to the power supply via molex adapters they came with. I was wondering how i would go about connecting all the fans so i can control their speed because right now its stupidly noisey and there is no need for them to be going full blast as the temperatures are very low on everything. I have had a look into fan controllers and such but i dont really understand how they get wired in and if i can use them with my system. Also i would like to know if theres any cheap way of going about doing this? Thanks for any help or advice x
