Reasonable Alienware R11 CPU Core Temps

I bought an Alienware Aurora R11 back in early 2021 with an Intel Core i7 10700KF with liquid cooling. Its under warranty until next Feb. I noticed occasional CPU Core Temps spiking up to 100C when under light loads. I'm using HWINFO for reading temps. I'm seeing what I think are high CPU core temps when doing simple tasks like data backups. For example, just backing up a few gigs of data to an USB drive or Cloud service provider is getting my Core Temp up into the 80s C. When purely idle I see averages in the 40s. I've confirmed all the fans are operating properly, ran the Dell diagnostics and made sure the BIOS current. I know Dell AW PCs are known to be poorly designed for heat dissipation however are these temps normal. I could understand running hot if I was gaming but this is just casual use? Is this something I should have Dell look into given its still under an extended warranty?
