case fan on motherboard

[allan71]

ok well my mother bought a compaq mini tower, i have cleaned it out and reapplied heat sink compound . i noticed it did not have a case fan , so i put one in and hooked it up to the motherboard . but it will not come on , so i just hooked it up with the power connector . my question is it normal for the motherboard case fan plug not to work when there was not one in it to start with?

Might have been disabled in the BIOS.

I don't know that particular BIOS but stuff like that is usually located in power saving options.

i have looked in the bios and did not see anything in the power settings for the fan. i googled the motherboard and setting the bios and found that there was no way to access the fan bios. so i don't know i guess i'll keep it hooked up to the psu with the molex cable. here is a picture of the plug that i hooked it up to ,https://scontent-ort2-1.xx.fbcdn.net/v/t1.0-9/14333158_10206882160644666_6780001408034654081_n.jpg?oh=2036be7730301a4ed56060cb5a427296&oe=583D79DF
