PWM means Pulse width modulation, Basically when a 4pin pwm fan is plugged into the cpu fan header, the hotter the cpu becomes, the faster the fan will spin to try and cool it

Hmm I found the SA fans easier to fit. What are you having problems with? Remember to install the fan clips into the heatsink first before securing the heatsink itself. Then simply clip the fans on. No point sending one back to get the other because it's a waste of money.
