3 pin to 4 pin?

stix · 18 May 2007 at 00:21

I have an Abit IN9 32 max mobo which has a 4 pin connection for the CPU fan.
I fitted a Noctua NH-U12F cooler and fan and this comes with the three pin fan connector . Course this will fit in one of the nearby Aux fan connectors but although that aint good practise it also prevents me from booting up as i get a post error either 8E or 8F . This is purely because there isnt a fan connected to the 4 pin cpu fan connector.
Is there a three to four pin converter i could use or will i have to get another 120mm fan for the Noctua heatsink? The only four pin ones i seem to see are the molex PSU type so im a little stumped at the mo.
Any help appreciated

I dont have the board but Im sure you can plug the 3-pin into that 4-pin CPU no problems

there is raising plastic bit that will make sure you can only plug the 3-pin fan connector in a correct way. Alternatively, you could just go into the BIOS and find the option to disable fan monitoring (had to do the same with my Asus, not sure about Abit)

Plug the CPU fan into the CPU fan socket. It fits because the 4th pin is for a different sort of fan. Thats why the 'key' on the socket is offset.

Thx for answering ken / Philly.... i did have a lil look in the bios but must have overlooked the option or missed it, my bro mentioned that he 'thought' you might be able to plug it in anyways but i thought id better find out first as i never had to do that before and didnt want to zap anything.

All 4 pin fan header are legacy compatible I believe.

Heh, similar thing on my Abit except I watercool the CPU. First time I booted it the siren was going because there was no CPU fan signal and my missus goes 'you better not have ******* broken it already!' :rolleyes:

got to love that!

Took me ages to work that out on my first water cooled system, was looking at it for about a hour before it clicked 8-)

Lol. The only plug i missed recently was the PCI-E for my 8800. It was screaming at me so loudly i panicked and knocked it off at the wall. Then realised what the problem was.
