the mobo im planning on buy is ASUS M2A-VM, heres a link to it: http://www.newegg.com/Product/Prod [...] 6813131172,

Almost all modern boards(this one included) has a 4 pin cpu fan connector. All the 4th pin is for is a PWM(Pulse Width Modulation) single to control fan speed. Either way a 3 pin fan will run on a 4 pin board and a 4 pin fan will run on a 3 pin board. Speed control with voltage still works on a PWM fan....and if you run a 3 pin fan on a 4 pin board there is an option in the bios to control fan speed with voltage...

As you see it's a normal plug with an extra pin....Left side is a 3 pin right is a 4 pin plugged in...

Ok, but sometimes, like on my mobo, stock from dell dimension e521, it only has a 4 pin, but if u were to buy it from other sites or companies, they should have 4 pin correct? for example; my mobo wouldnt allow a 3 pin due to the little slits to keep it in place, but others now can do allow you to connect it with out the slits?

Some dells(new ones) will use a 4pin pwm others used a 4pin dell proprietary connector
