CPU @ ~90% load for hours every day

I have Ryzen 2700x (8 cores/16 threads) and using one program that uses up to that number of cores/threads. Program is making some kind of sims to high precision which may take several days of running.
I was just wondering is it bad to use CPU at high loads (90%) for 5+ straight hours every day.. like will my cpu die faster or something? (and how much faster are we talking about? 1y life time, 3y life time etc..)

Ryzen 7 2700x, ASRock X470 Taichi, G.SKILL Ripjaws V 3200mhz CL14, Samsung 970 Evo 1TB, MSI GT 1030, XFX TS 550W, Fractal Design Focus G

Nah, not a chance. Just keep temps at reasonable levels (below 80) and its lifespan will not be affected.

Even consumer CPUs are made to operate within spec for years under any load.
I'd have no issue with running a desktop under 100% load for years at a time, let alone days.
A few days doesn't even register on the degradation scale.

This is what it was made to do, not sit idle like most processors

Don't forget the motherboard. Make sure you're cooling the VRMs.

Yep like other have said your system will be fine. Just be sure there is adequate cooling so nothing gets too warm.

I ran folding @ home with my cpu at 100% load for probably close to a decade on the same Intel Q6600 processor I now have powering my home server. Still works like new to this day.

Does CPUID hardware monitor shows temperatures accurately or I should download another program? It says ~59C/137F for CPU which seems kinda low. For MB there are SYSTIN (40C), TMPIN 5 (65C), TMPIN 6 (40C), TMPIN8 (21C), TMPIN 7 (68C), TMPIN 3 (40C)

Case that I'm using is opened and just 2 fans in the front (they ain't doing much ). Should I put one fan in the upper left corner to blow air to this upper left area where is passive cooler with asrock letters (I guess VRMs are there?

59c doing what?
CPUz is fine for that but HWinfo will let you see everything.
In my case leaving the side off actually makes things worse...but my fan locations are on point.

CPU temperature (Tctl) is actually ~66C when under load.

I bought new 140mm fan just in case. Here is picture where I meant to put it but noctua's fan is putting air to the left while this new fan would put air into that air that comes "out of cooler". Is that a problem?
(green color would be fan and blue are VRMs, red is noctua's fan and direction of air)

Sorry for the noob picture.. not trolling
