Hi guys,
this is all great info thanks.
Boncuk,
a) you said this is not a good choice, I assume you mean the choice of Mosfets rather than the fact that they are paralleled? I happen to have a P4 heatsink and fan combo waiting for a job. Any suggestions for the Mosfets?
b) I don't mind whacking 4 Mosfets in, there is lots of space where this is going. If I used 4 would probably take them offboard and arrange around the heatsink in a North, E, W and South arrangement with a ringmain connection
c) what drawing program are you using?
d) on the gate resistors, based on your comment one obviously needs one per Mosfet? I have been trying to teach myself electronics with LTSpice, playing around with values etc. The one 390R resistor feeding 4 Mosfets gives the same output trace, what am I missing here?
e) Would the Mosfets in the Spice model be better?
f) What are the connections for the P4 fan, G, B, Y
Cheers
Andrew
