Conventional vs Synthetic plus viscosity, does it truely matter?

I haven’t checked anywhere but knowing the temps, and someone that’s got more than 8 months of seat time in a rear wheel drive and the behaviors of open dif vs lsd, I’m curious if anyones noticed the temp at which the stock lsd starts to act as an open diff. I live in New England so I don’t see the high ambient temps like someone in Florida or Texas, my diff may not get to 275 but I wouldn’t know. If the silicone in the viscous unit breaks down at 150 a cooler wouldn’t help prevent the open feel. If it breaks down at 250 and I never get above 235, the cooler would be a waste. At least in my head and the purpose of it.

When I still had the VLSD in my Z. First started doing trackdays. It was fine at first. As I had more trackdays. It would start to fade away towards the end of 30 minute session. The more trackdays and the more mileage on it. The sooner it would fade. Towards the end. I could make it fade around the 15 minute mark. Just doing street. You should be fine for 50,000 miles at least.
