How do you change the fans turn on/off temps to a lower temp ?

Yes, I would concur with JFP in PA, the only other thing I would add is that with the a/c on, the water temp stays in the low state longer, even in a traffic jam.... esp now that both my fans work.
Definitely a recommended mod. But it doesn't increase the ultimate cooling capacity (as espected). Just keeps the engine running cooler longer.

we discussed this a bit on another post, but something that strikes me as weird / dangerous about this motor's design is that the thermostat is on the INTAKE side of the engine.
this means that when it opens, cool water from the radiators will flow past & it will start to close again. this is contrary to ALMSOST every other motor i've seen. so, our 190deg thermostat is actually trying to maintain the cool radiator water at 190, NOT the hot side. this strikes me as a) pretty hot and b) pretty dangerous.
that having been said, this realization has made me a firm believer that the low temp thermo is the correct way to go.

The fans are controlled by the DME, changing the on/off temps would require reprogramming the unit.

This is a modification I definitely want to do in conjunction with the 3rd radiator modification. I'm all for colling this car down, it amazes and concerns me at times just how hot this thing can get. I almost want to leave a big fan blowing over it when I park it at home.

when you do the 3rd radiator, let me know. i figured out how to increase the back-spacing & shoe-horn the 996 turbo duct behind it.

I will definitely do that, insite. You're saying you're able to get that duct to fit behind an OEM S bumper? Does it require any modding of the opening on the bumper?
Sry for the minor thread hijack, feel free to PM me instead if you want, insite.

it will fit behind the S bumper w/ no issues. it's designed to vent out the bottom. you may need to cut holes in your bumper under the car to vent the air. mine has the GT3 nose, so the vents were there already.
