117K and have never had and over heat issue. I tow a goose neck with 15k on it and several other trailers. As for fan noise, well it won't cool the engine if its not making noise.
I never had any problems.......I just made it all up..... It was the absolute best truck I ever had.. I towed tractor trailers up over the summitt and it never even got the slightest bit warm... It had so much power stock it spun all 4 rear tires all thru the gears.. ... Hey guys its all good.. I have been reading thru all the old threads on this site.. it seems way back in 2004 some if not most people said there trucks never overheated.. maybe we should start a new thread on how many people have overheated their lly's not how many have not.. Honestly.. dont know why people have to take offense to others that have had their trucks overheat and leave them sitting on the side of the road. Thats not very fun with a wife and infant in the vehicle. And I have said many times... mine was a LEMON. not just with overheating either.. All manufactuers have lemons.. Ford had many "lemon" 6.0's that were bought back. Not sure about the cummins. It all boils down to whatever you like.. buy it, enjoy it then hope its not a lemon.
just my opinion and personal experience with my 2005, maybe most of the lly's were the best..
