Negative pressure as in more intake fans than exhaust fans right? or vice versa?

After much troubleshooting, the water temp probes will not work with the BigNG. This is a warning to everyone else so that they also won't make the same mistake. The BigNG requires that all temp probes have a resistance of 10kOhm to be compatible.

I went ahead and purchased some different ones instead: http://www.mcubed-store.com/catalog/...roducts_id=149

and will be inserting them into some AC "Plug and Cool" fittings to get water temp readings.
