Hi,
Has anyone soldered the mosfet tab to the pcb, and if so how did you do it?
thanks

I wouldn't do it, no need, you're just opening the door for complications IMHO.
There is absolutely no reason not to do it.
No reason to do it, the Mosfet isn't gonna over heat driving this blower or even one quite a bit larger. The tab is there to contact a heat sync, I don't see the logic behind transferring heat to the circuit board, that's not where you want the heat to go.... and typically they are held to the heat sync using some sort of clip rather than actually soldering. If you ever have to troubleshoot the blower circuit good luck getting the MOSFET off without damaging the board. So I still say don't bother, could cause more harm than good.
But the heat sink is the ground plane. The Eagle cad part is is designed for the grounding tab. Virtually all mosfet of this type are grounded to the ground plane.
