Quick question. Anyone know off hand the temp at which the fans kick on with a stock tune? Thanks

I would like to thank Steve for posting the strategy of the radiator cooling fan operation. I am slowly working out of bugs on the last 2011 that I picked up. After I recharged the AC from swapping cams, I noticed that the fans ran at a lot faster speed than the first one I picked up. I popped the hood and started the troubleshooting and I noticed only one fan was running. I would hate to hear the air noise that both of them running on high speed. After read Steve's post, it was obvious that the one fan not running was open, which prevented both fans from running on low speed and the head pressure was getting high enough to switch the fans to high speed. Installed 2 new GM motors and now they act and sound like fans on the wife's car.
