Volt Modding a fan question

xirokx · 10 Apr 2006 at 18:41

Hi,

I have just bought a random 80mm fan that runs at 12v 36cfm 34dba....

I'm sure I read in one of your guides yewen I can get the same cfm and dba at 7v?

Is this true or am I a confused bunny?

Please advise

Cheers

ahhh...I got it....

Where is that guide? I remember seeing it whilst surfing around the other day

Also is there much difference in air flow and noise levels if I was to reduce the voltage to 7v?

cheers matey

Unfortunately my case fan has three pins only I do have the four pin connector but dont use it....

Am i stuffed?

where does it plug into on the mobo? or a female connector wire type thingy off the PSU

xirokx · 10 Apr 2006 at 19:06

how many molex connectors does 1 psu have?

I mean I have 2 case fans

Sorry just thought I would ask here before opening up the pc

I have an old psu but do they all have same number of molex connectors?

should the blades for the front fan be facing the front and the blades with the protector at the back? dya know what i mean?

Unfamiliar with daisy chaining...

I have molex connectors which my fans can connect too however does the three pin connector apart of the 4pin adaptor that came wiv my 80mm fan then connect to the mobo or does it stay loose?? Basically once I connect the 4 pin adaptor to the 4 pin molex connector do I have to worry about plugging the three pin in anywhere???

yes but which way do you fix the fan to the case?

So if I just plug the 4 pin adaptor from the cooling fan to the psu molex connector that will be fine will it?

so by connecting the molex up to the four pin adaptor on my cooling fan it will automatically be running at 7v instead of 12v?

So which way do you attach the fan? With the blades (without the protector) facing the front?
