12v 60mm Vs. 7v 80mm

A holesaw works best. I have made many of these fan adaptors and the first ones were cut with a fine tooth jigsaw but I now have a holesaw and it works way better.

Just put the sheetmetal into a flat scrap wood and screw it in place using to holes where the fan mounts then cut with the holesaw.

alright that i will do at school because they have holesaw's there. i hope they have a 77mm one

A 3 inch holesaw is 76mm.

Even a 80mm holesaw would still work fine.

No problem at all.

I have put an 80mm fan on my heatsink..you say the 60mm blows more..how can I make the 80mm fan 12 volt so that it will blow more?

it probably is already.

the red wire should be going into the yellow one on the molex and black to the black. for 7v it is red fan to yellowmolex and blackfan to red molex. 5v is red fan to red molex, black fan to black molex.

Its plugged into the mobo lol

then it is running at 12v for sure, if u want to make it slower though you can cut teh wires and somehow attah them to the molex.

edit: dont do this for a cpu fan, its deadly (copying VB lol)

Don't slow it down with the 7 volt trick for the CPU.

Starting a fan at lower than rated voltage can sometimes cause the fan to not start (sticks a little). That is deadly for a CPU.

If you really want it to turn slower then find a fan that has a slower speed without lowering the voltage.
