CPU over-burdened by running at 98-100% permanently?

[Erich56]

CPU Intel i7-4930k (default clock: 3400MHz), HT switched on, hence 6+6 cores.
Mainboard ASUS P9X79WS. 32 GB RAM. OS: Windows10.

When crunching grid computing tasks, I usually run five 2-core tasks of a given project (so 10 out of tatal 12 cores are being used).
If the Turbo Mode in the BIOS is switched to "auto", it yields a CPU clock of 3600MHz, and in the Windows Task Manager, total CPU load is shown as 92-93%.
If Turbo Mode is at "manual", the CPU runs at 3900MHz, and the total CPU load is shown as 98-100%. With temperatures still okay (due to a heavy duty cooler: 65-66°C - Tj.Max is 90°C), and power usage also okay with ~ 104W (TDP=130W).

Still I am somewhat worried whether the CPU might suffer when running at it's limit permanently (24/7).
What's the opinion of the experts here?

As long as your manual settings doesn't change the voltage that goes to your CPU there is no consequences, CPUs and every other component of a computer are made to run "forever" .
What you should be concerned about is your PSU failing in a spectacular way and frying other components which is why it should be replaced or serviced regularly.

Yes, every computer in my house runs@100%load 24/7/365 but with good cooling and great PSU's. I have done this for like 15 years, and never fried a CPU or PSU.

Well, I guess I wouldn't have to worry too much about my PSU at this point. It's a 1000W Corsair Professional Series HX1000i, 2-1/2 years old. So I hope, at least, that this should be okay.
