Hate to sound ignorant here, but if you don't ask you never know right.

There are two temp sensors giving readings on EVIC. Water temp under "system" and engine temp under the hidden menus.

Which one controls when the fans come on? I'm guessing its based on engine temp, and not water.

I have a 180Tstat installed, and kept getting 205-210 on the water temp side, couldn't figure out why. Then today I noticed the Engine temp stays around 190 now, maybe 194 in traffic. This is running the straight Diablo tune fan settings. I will probably turn downt the low speed settings to hopefully keep it to 190.

So how can the water be hotter than the engine? It's the engine heating the water. Is it just where the sensors are located?
