Do I need to upgrade my alternator with these fans?

Thanks Billgrissom, I’m not exactly sure on the thermostat, either 180 or 185 I think, I got it awhile back, but I’ve been driving the cuda the past couple days and it stays at 180-185 driving and then after 30 min or so of driving yesterday, I let it idle for about 10 min and it didn’t get above 190. I think I might be ok. That was also in 70 degree weather though. I’ll get a shroud if it doesn’t do as well in 90+ heat
