Do you know how long a datacenter manager (or network engineer) will let a machine in a datacenter go at temps of 100F let alone 185F? About 10 minutes before alarms are going off and they’re scrambling to figure out what cooling equipment failed and fix it. So yeah 3000 hours and the new 5000+ hour results with no impact on performance is MORE than satisfactory for real world applications
Edited to clarify that 85C is 185F (source Google - but I’m sure it’s in a white paper somewhere)
