Sort of. You're ok on the 247, but I'd go with more like 240 to start with. But 50 on the hysteresis is ridiculous. Leave it at 5. But go test it; at what temp does the fan come on with the changes? Does it decrease temps? If so, what temp do they turn off? Test at idle and at speed...does the temp decrease at idle with the fans alone, or does it take some air movement (car at speed) to get temps low enough for fans to turn off?

But seriously...don't do something because that's what some Joe Blow on the interweb said. Read what they said, understand how/why, and verify against the sources at your disposal. Then do something because you actually understand what you're doing.

 

This should be shown on the google homepage to let everyone know what the proper procedure for using internet advice is.

 

Alright thanks for all the info, and the hottest it got was 187 so it really never got hot enough for me to check if they went on cause i only drove around the block cause my insurance doesn't start till Friday , but when it does i will check from there thank you once again. And i really dont give a **** if im on your ignore list i already have a fan club...
