I would suggest oversizing the transistor.
Due to the PWM you are using it heats up quite a lot, the continous switching of 5A at 1KHz is quite intense for a resistor..
Blew 2 transistors that way with PWM speed control on my fans, oversized the transistor and added a heatsink to it and it works like a charm now
