I wouldn't call the E46 M3 'modern'. Whilst I wouldn't like my temp to move from the centre, I can understand why an engine like the S54 which was developed to extract almost as much power as possible from a NA 3.2L engine could be susceptible to some heat issues in extreme conditions (AC, 40deg days, being driven hard).

It's not like they are overheating and pissing out coolant. They are just getting a bit warm when they are under stress.

When I went on my track day I didn't use AC and it was 30ish degrees outside. I had no issues with heat there. It just seems like adding the extra stress of a few degrees in external temp and a 10yr old AC system working overtime causes things to get a bit hot.
