Question New Build Running Hot on P95 Stress

[GorfTheFrog]

Hi -
I have a new build, and I'm uncertain on the temps I'm seeing. Would appreciate any thoughts.

i7-13700K CPU
ASUS Prime Z790-P
DeepCool AK620 Zero Dark Dual Tower / Dual Fan

Right now I'm running with an open case and no overclocking or any other mods.

Using HWMonitor to see temps. At idle I'm between 28c-33c.
When I run Prime95, within 1min 30sec I'm seeing multiple CPU cores hit 100c.
When I stress test with CPU-Z I hit max core temps between 66c-83c.
Fans are ramping up RPMs as expected as the temperature increases.

I'm not overclocking, so I assumed that my air-cool setup should be able to handle P95, especially with an open case.

It's been a while since I built. Prime95 used to be the standard for testing stability, but I've seen a few threads that indicate it may be overkill and not the best measure anymore. Any better suggestions?

I'm building this as a gaming rig for a family member, and I want to be sure that the system is stable before I hand it over.

Graphics is NVIDIA GEForce RTX 4060 TI. FurMark maxes at 69c.

Thanks.

Usually those temps are expected even with good air coolers on your CPU It draws a lot of power (250w) and also makes a lot of heat for that power. The best you can do is to have good airflow in your case, and making the fan curve so that it goes to 100% speed when it goes near 100c temps.

If when gaming, the CPU isn't going so high, you're fine, and the system is stable. Even while stressing the CPU, it doesn't turn off or anything, its stable. It will throttle and keep temps under its limit it can handle.

13700K will quickly go to 100 if that's what it takes to do the job you ask it to do.

As far as I know, that's true of Intel recent generations in general.

Deliberately, by design.

Idle looks great; CPU-Z looks fine.

I've heard it said repeatedly that Prime 95 temps are NOT representative of real life workloads.

Not sure that an open case would have lower temps than a closed case with good airflow.

Hard to shrug off previously-held ideas about "acceptable" temps.

Cinebench isn't quite as heavy as P95 so I'd suggest running that to double check as it's a good multicore workload. It would also be worth checking to see if it is thermal throttling. The AK620 is going to be right on the edge of anything 13700K+ as they do have 253W TDP (Asus keeps to stock, but it'd be worth making sure you're not seeing anything over this).
