Adjustable Temp Electric Fans, Need help finding a sensor--page 2 Options

[computers4kids]

Currently I have dual electric fans, each on their own relay, that both come on around 180 degrees. I would like to reduce the fan noise from both fans coming on at once since my system stays cool easily and both fans tend to be overkill. I was thinking about having one fan come on around 180 degrees and the other come on if the temperature raises 10 degrees or so above. Fans 1 and 2 would also shut themselves off once each one dips 10 degrees below their set temps.

I see Jegs sells a kit that appears to do just this for around $150 that would control both fans. http://www.jegs.com/i/Derale/259/16789/10002/-1
Another possibility, would be to let Fan 1 continue to come on at 180 using the temp sender Renegade supplied, disconnecting the Fan 2. Jegs also sells the same adjustable unit for a single fan for $83. I would connect Fan 2 using the single controller for half the price. http://www.jegs.com/i/Derale/259/16779/10002/-1

What are your thoughts?

oh DUH....

My Eurovan has this.
Look for the temp sensors (and associated inline hose fittings) on a 1993 VW Eurovan parts diagram. There is a plastic housing for the standard Bosch sensors that fits a stock size rubber hose...

As stated above, both sensors are on the outlet side of the radiator.
Three sensors all together, two of them run the fans on separate circuits.
One more for the ECU.
