Under load ... 88 degrees celsius ... i5-9600k ... hyper 412r ... haven't overclocked ... airflow in my case is good ... is it okay to let it get that hot?
xot1ko,
On behalf of Tom's Moderator Team, welcome aboard!
Although "Throttle" temperature is 100°C, cooler is better for ultimate stability, performance and longevity. Accordingly, it’s never advisable to run a CPU near it's thermal limit. Here's the nominal operating range for Core temperature:
Core temperatures above 85°C are not recommended.
Core temperatures below 80°C are ideal.[/B]
• What was your ambient (room) temperature?
The "standard" for normal ambient temperature is 22°C or 72°F. All computer temperatures increase and decrease ~ 1:1 with ambient temperature. We have members who live near the arctic circle with indoor ambient at 10°C (50°F) or near the equator without A/C at 40°C (104°F). Ambient temperature can be a HUGE variable, so we need to know.
• What case, and why only a CM Hyper 412R, which is a 92mm fan class cooler?
A six core processor that's capable of power consumptions near 150 Watts should have a more capable 120mm fan class cooler, especially for those who intend to overclock.
• What "load"?
Loads vary widely. Intel validates Thermal Specifications using a
steady-state (non-fluctuating) 100% TDP workload. Only Prime95 version 26.6 running the Small FFT's torture test meets that criterion.

When discussing processor temperatures, there are 3 major variables that must always be considered:
(1) Environmental conditions
(2) Hardware configurations
(3) Software workloads
The information you've included addresses only the hardware aspect of these variables.
In order to provide any meaningful conclusions, it's always necessary to state what your ambient temperature was at the time of testing, and exactly what workload was used for testing. Without this basic information, it's impossible to compare apples to apples.
Please provide more complete and specific information so we can best help you.
Also, I strongly recommend that you read our guide: Intel Temperature Guide -

It's a Sticky near the top of the CPUs Forum; if you look you can't miss it. Nearly all our Forums have Stickies, which are threads that are informative resources permanently "stuck" in place and are always available as reference material for everyone's benefit.
Once again, welcome aboard!
