You throne plug a 4-PIN PWM fan connecter into a 3-trap period of time on the motherboard without any problems. Without the fourth flag connected, the fan will just campaign at full speed.

As faraway as climbing the fan, some fans don't have the holes in the side threaded for screws, so the screws will need to cut their own threads in the lover. Just make sure they are centered, use a good-fitting screwdriver, and use a little of muscularity to get them in.

A 4 pin sports fan will work with a 3 thole motherboard rooter slot. The fourth pin would represent used for dominant winnow cannonball along so you will not have that functionality. Just about pillowcase fans cause not have pre grooved holes for the screws so when you initially put the screws in it's going to shoot a small sweat.

You can plug in the 4 pin fan with your 3 trap motherboard. The sports fan will simply run at full speed. The 4-pin fans are often referred to as PWM fans, because the 4th connector is the what the motherboard or fan controller uses to modulate the big businessman allowing the speeds to change. If you corrupt a aftermarket fan accountant, you can use the 3-pin fans in the same style as a 4-pin fan. I use 3-pivot fans with a fan controller since my motherboard doesn't have sufficient fan headers for my case.
