Installing more Case Fans

post #1 of 7
Thread Starter 
G'Day Overclock.Net,
I want to put some more fans in my case but however I do have a slight problem. My motherboard only has 3 fan headers and I need 6 headers to power my case fans and water cooling unit.

The fans I will be installing in my case are these.

I went on ebay and bought a 3 pin to molex to power these bad boys but there was a problem.
http://www.ebay.com.au/itm/300675023381?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

They weren't spinning fast in fact they were very slow, I thought maybe I got a dodgy cable so I tried another (I bought 8 for $1 each) and still the same problem. I put the fan into the motherboard header and it works fine.

So my question is that I know the third pin on an adapter is meant to control the RPM, But is there a chance these fans need 3 pins to power them instead of 2 pins? Also if that is the case will this adapter give me full speed for both fans or will it be splint into 7 voltage?

+1 to this. I have no idea why I didn't get one of these earlier. When the PC is idle I can crank all of them down to 400RPM and it's almost silent, and you have no problems with headers, I have 4 fans on the controller using one MB header

Your problem with the converters is that it is tapping off 5V not 12V, the yellow line is 12V

Thanks for the reply,
So does this mean that if I buy the fan splinter located above it will deliver 12 volts to both fans or 5 volts each fan?

Splits out from your motherboard.

This one splits out 12V
