3 pin wire into 4 pin connector, crap. So no way of controling fan speed huh?

Probably not. The way the PWM fan spec is designed, if you plug a non-PWM fan into a PWM header (or vice-versa), the fan runs at full speed all the time.
Some (but not many) motherboards have an option in the BIOS where they will emulate the PWM function by varying the voltage on the power lead of a 3-pin fan. Check your BIOS for any other options related to fan speed control.
Assuming your mobo does not have that feature, the only way you're gonna be able to control the fan is by replacing it with a 4-pin fan that supports PWM properly.
