Its that time of the year again and I have decided to get rid of the choke/clutch fan. I just love how quiet and smooth start-up is. MPG improves, engine stress reduced and it idles nice and smooth with out the belt choker fan. My plans are to install an automatic switch, or if i were able to easily wire it up to the green light that comes on with the cruise control, I would consider that if its easy. My second question is where to mount the temperature switch if i dont link it to the crusie control light?

dual 16' fans 2700-3000 cfm : $75 delivered
temp swtich: $18.95 delivered

You need a fan shroud for those, if they don't come with one.

And be prepared for the inevitable clutch vs electric fan argument...

Temperature sensor can be mounted anywhere in the engine bay as long as its not on a hose or touching something hot, it doesn't matter.

The manual switch would work but occasionally you'd forget to turn it on or off, it might be a pain. I have mine running all the time, it's been working well so far.

I have heard the arguments about keeping the clutch fan, and why electric fans don't work well on the 7-m. I just love how it drives w/o it, the car feels like i unhooked a trailer. By the way, i think my choke fan did nt spin as freely as it should have and i dont want to buy a new choker. I thought about using the OEM shroud + 1 electric fan, but i think two "slim"14-16 inch fans would work better and would be easier.

The ebay auction says "Low Drag Cyclone Blades Pulls 1600 CFM (3200 for the Pair) at Full Speed, Putting the Factory Fan to Shame"

edit: I forgot to ask, do you think I would be able to screw that temp sensor into the thermostat housing, and just get rid of that vsv vacuum switch. The threads and size of oem vsv switch and the aftermarket temp switch look close i could just swap .

edit:I am all thumbs with diagrams of wiring. I need a cruise control guru to help me out about adding a fan relay up to the green cruise control light that comes on. The CC unit under the hood is near the battery, so i was thinking of tapping into one of the wiresif possible and adding a fan relay in the cruise control wiring near brake the booster.?

agreed with what is said so far, however I differ because I am a fan of the on/off switch, just gotta make it a routine to start the car then start the fans.

I say this because of the the few people I know who have converted them the sensor eventually went bad and fans wouldn't kick on, overheading the car (1 supra, 1 v8 s10, 1 rx7)

however I still think its a good upgrade despite what people say about a clutch fan.
