Had some concerns about the SMEC not getting cooled due to use of a cone intake air filter, car came with the cone otherwise I would had left it stock, anyways... heat certainley reduces electronics life, therefore I need cooling.
It's simple, but I have seen many talk about or do this, this is my take that came out quite nicely.
Turbo 1 plastic piece that bolts on the throttle body, hose that goes with it and a PC style 12VDC electric fan, some screws, 2.5"ish hose clamps and wiring shit.
The bolt holes on the TB plastic line up perfectly with the fan, and the opening is just the right size. Mounted the fan to that, cut the intake hose just short enought to fit the TB plastic and go onto the computer mouth (lucky they are the same size). Mounted that and got the switched ignition 12VDC from the single blue wire on the Fan relay, and ground from the bolt that holds the fan/starter relays on.
I find this is actually effective. Why? Well after some driving and coming to a stop and idling, the fan is pulling hot air out of/through the SMEC. Best keep her cool!!
Keep in mind the engine bay is strictly functional :)
