Are these temperatures within acceptable limits?
Are these temperatures within acceptable limits?
Hi,
I just installed my CPU and wanted to check if the temperatures are within normal ranges.
My system details are:
CPU: i9 9900k
AIO: Corsair H100i Platinum
MB: Asus ROG Strix z390-F Gaming
Ram: Corsair Vengeance RGB DDR4 3000 MHz RAM - 32Gb (2x16)
SSD 1: Seagate 2tb Firecuda 510 M.2 NVME (boot)
SSD 2: Samsung 850 Evo 1tb
HDD: WD Black 3Tb
GPU: MSI RTX 2080Ti Trio Gaming X
PSU: Corsair HX1000
CASE: Corsair 780t White
OS: Windows 10 Pro
Screen resolution: 2k
Overclocking at 4.8Ghz completed using the Asus ROG Auto AI optimization in the BIOS.
Here are the CPU-Z reports:

During normal daily use (many browser tabs, code editors, FTP software, Slack, Skype running), temperatures stay around 38-50°C.
Playing Shadow Of The Tomb Raider averages 40-50°C – occasionally up to 60°C.
Metro Exodus reaches 60-70°C, with a peak of 75°C on a hot day with coding, browsing, and an hour of gaming.
Stress testing with Realbench for an hour reached a max of 87°C.
It’s a cool morning now – temperatures are between 32-35°C while I’m writing this. There are 8 Firefox tabs open, Slack, Skype, and a few other lightweight apps running.
Just run a Cinebench test and the temps come down to about 85°C – see here:

Do these readings look normal? The Realbench result was a bit concerning.
It's perfectly fine, the temperatures are also nice. Asus AI optimization works well but usually increases voltage more than a manual setting. You might be able to achieve a very low Vcore around 1.25v or even lower for a 4.8GHz all-core and 5Ghz all-core processor after some adjustments. There are many guides and discussions about overclocking the 9900K that can assist you in fine-tuning your Vcore and clock speeds, since this CPU performs well when overclocked and still allows for stable temperatures with proper tuning.
I believe I shouldn't be too concerned, especially with these temperatures. Based on what I understand and what others have said, it should remain stable even a bit more. A temperature of 87 degrees during an hour-long stress test seems acceptable. What matters most is how the system throttles and whether it continues to raise temperatures significantly above 100 degrees. Some of his 'brothers' are reportedly handling even higher temps, like 104-113.
Same mainboard but with a 9700K CPU. Temperatures are within acceptable range. Both 9700K and 9900K get quite hot. I use an air cooler (Artic Freezer 34) and can easily see temperatures reaching 85 degrees without overclocking during Battlefield V. (Reminder: 85°C is the peak, and my CPU stays between low to high 70s most of the time)
Feel free to relax, the temperatures are also favorable. Asus AI optimization works fine but usually increases power consumption more than a manual setting would. It’s possible with some adjustments to achieve a very low voltage core voltage around 1.25V or even lower for a high-core 4.8GHz and 5GHz all-core configuration at about 1.3V... There are many guides and discussions about overclocking the 9900K that can assist you in fine-tuning your Vcore and clock speeds, since this CPU performs well when overclocked and still allows for stable performance with reduced voltages through proper tuning.
Respectfully, it's not advisable to suggest running a CPU at such high temperatures. This information comes from Intel's engineers:
Inside Intel's Secret Overclocking Lab
- Refer to sections 7, 8 & 9
The Tj Max rating for the i9-9900K is 100°C, which is already excessive.
On Intel’s Product Specification page, you’ll find details.
Package Specifications are listed on the Intel website.
Datasheets mention page 99, Table 5-4.
It’s worth noting that 9th and 10th Generation "Z" motherboards allow BIOS settings to push Tj Max by up to 115°C—something many manufacturers should avoid. Allowing users to override this setting for competitive reasons is a serious concern. Disabling CPU Thermal Protection is equally problematic.
The typical core temperature range is:
Above 85°C is not recommended.
Below 80°C is ideal.

What does a "cool morning" mean? What’s your room temperature?
Core temperatures change with the surrounding air. The standard for a normal room temperature is around 22°C or 72°F.
