I try to NEVER hook fan headers to the mobo, dunno if its my luck or not but seems like them stupid fan headers kill mobos faster than a -192c 2.ovolt Overclock does.

Fact. I don't use them either. Most headers will only support 1/2 an amp for fans even though most manufacturers say they're good for 1 amp. I've killed too many good boards because of this. I make it a point to hook all fans directly to the PSU or a controller now.

From now on I'll not hook them to the board. How many volts do regular fans need?

12 for full speed. Some will run under 5V though. Usually the ones that run very low still need a higher startup voltage.

Most fans will fall into the .15-.25 A range. with beefier ones hitting .25-.6

Then of course you have the "never designed for a PC" Fans that people like to strap to heatsinks and stuff the Amperage can really shoot up on them
