Do you know the batch number of your 3950X?Interestingly I've ran Prime95 this morning just to check my cpu temps again and was shocked to see that it quickly climbed up to 86C with my cpu clocked at 4.2ghz using 1.1875vcore. Now this is not what I usually saw when testing with this cpu speed. Found a new bios for my MSI MEG X570 Ace and flashed it but thought about the temps and decided to just check the Corsair IQUE software to check the pump speed. Interestingly it was reset to quiet and the pump was barely running 1000 rpm. I set it to extreme and ran Prime95 again for 31 minutes or so and was happy to see temps was just reaching 70c on one CCD. I'm pretty happy with the setup as is.
