CPU fan Header and Thermalright U120 Question

Just about to install an aftermarket cooler on my mobo, but the aftermarket fan has a 3pin connector, while the motherboard has a 4 pin socket!

Can i still connect a 3 pin to a 4 pin socket? and if so what ill effects will this have on the operation of the CPU fan?

Ok that sounds good, but does that mean its running at full speed all the time? or are the RPM's still controlled by the Mobo?

Oh another quick question: how tight should i screw the thermalright Ultra 120 to the mobo attachment? is the retaining clip supposed to be seated to the mother board or are the legs "floating"?

CPU fan Header and Thermalright U120 Question

Thanks, i've got the x-bracket in place but just scared that if i tighten too much i will damage the CPU! Its currently not sitting 100% tight to the mobo but it does feel secure. There is wobble though, if i move it on purpose. is this natural?
This is my first build from scratch thus i'm well nervous!
