Best pl1 and pl2 settings for 14700kf

[Zak-ch]

Hi

I am using a 14700kf with an msi core liquid a13 240mm AIO. I undervolted the cpu -0.1v it’s running without obvious issues or crashes but I am still noticing high temps from time to time. In games most of the time it’s around 65 to 85 degrees with rare peaks for exemple in Clair obscur I can see brief peaks to 97 even 100 degrees in some scenes for couple of seconds. In some other games too. I am playin 1440p or 4k. In Cine bench I am getting around 31k score multi threaded test, in occt after 10minutes it’s around 95 degrees. Are these temps acceptable? Is this cooling enough? Can I tweak pl1 and pl2 , if so at what suggested values ?(currently in my motherboard it’s Intel default with pl1 and pl2 at 253w tau 56s, msi b760m gaming plus WiFi) thank you for your assistance

Hello Zak-ch,

Thank you for posting on Intel Community Forum.

About the high temperatures that you are reporting, I would like to gather more information to properly address this.

1. What is your idle temperature?

2. Did you notice this from the start of using the CPU?

3. Are you running any overclocking on the CPU or GPU?

4. Which software are you using to monitor temperatures?

Additionally, to have a better understanding of your system configuration and components please generate System Support Utility (SSU) report. Please follow instructions here and send the report - How to get the Intel® System Support Utility Logs on Windows*

I hope to hear from you soon.

Hi JedG_Intel, 

Thank you for your feedback. The report is attached. Here are also the information you asked for : 

1. What is your idle temperature?

It's around 30°

2. Did you notice this from the start of using the CPU?

At start, I had very high temps. It was adressed by reseating the pump and reapplying thermal paste. After that, temperatures where way more acceptable around the numbers I mentionned. I am more concerned about the spikes, except if this is expected and normal behaviour, and also by Cinebench R23 score. Also I wanted to make sure this is normal, and if tweaking PL1/PL2 wil do any good without a big drop in performance. 

3. Are you running any overclocking on the CPU or GPU?

No overclocking of either CPU or GPU. CPU is undervolted -0.1v 

4. Which software are you using to monitor temperatures?

I am mainly using HWinfo. Temperatures are similar on other softwares I used to double check (MSI center, NZXT CAM)

Hello Zak-ch,

Thank you for sharing all this information.

Regarding the temperature readings you are observing, please be assured that they are within normal operating parameters, particularly as the elevated values occur only briefly and not consistently.

Please note that we do not provide specific operating temperature ranges for individual processors or cores, as these values can vary depending on system design, thermal solutions, and workload conditions.

Processors have internal protections to prevent against excessive temperatures. Operating ranges below the protection points are highly dependent on system configuration and workload. The maximum operating temperature limit varies per processor and usually is between 100°C-110°C.

About the PL1/PL2 settings to use, we posted a recommendation for different processor models and you can try to utilize it by visiting this link.

For reference:

If you have other questions or concerns, please let me know.

Hello Jed G. 

Thank you for confirming that the values are within safe and expected ranges. 

Regarding PL1 and PL2 settings, based on Intel official default sheet you shared, I am on performance profile (253w/253w), which is the recommended one. Based on the details shared in our conversation, does this mean I should keep it or try baseline? (125w/188w) ? I didn't quite understand this remark "Intel does not recommend Baseline power delivery for 13th and 14th gen K Sku processors unless required for compatibility".  Is it to maintain high performance or any other reason? 

Best regards,

Hello Zak-ch,

What we recommend is that you continue to utilize the Performance profile both with 253W. This recommendation is based on our investigation and analysis. Intel's recommendation is aimed at ensuring that users can fully leverage the capabilities of their K SKU processors by using power delivery systems that support higher performance levels, unless baseline configurations are necessary for compatibility.

Below are the reason why Intel Recommends Against Baseline Power Delivery:

• Performance Optimization: K SKU processors are designed to perform best with enhanced power delivery systems that can support higher power levels and thermal management. Using baseline power delivery might limit the processor's ability to reach its full potential, especially under demanding workloads.
• Thermal and Power Management: Enhanced power delivery systems often include better thermal solutions, which are crucial for maintaining stability and performance during high-intensity tasks.
• System Reliability: Ensuring that the power delivery system can handle the processor's demands helps prevent issues such as throttling, overheating, or system instability.

If you have further questions, please let me know.

Thank you Jed_G for your very clear explanation.

As a follow up, I managed to solve the issue by replacing the AIO. It turns out the pump was not working perfectly. I upgraded to a 360 AIO (MSI MAG Coreliquid i360), I kept the performance profile and the undervolt. As a results, temperature is approx. 10 degrees less and spikes are alsmost never triggering thermal throttling, except in some rare cases (sudden very brief spikes, at some point with very demanding loads) and performance is smoother.  I am sharing this so anyone having a similar situation could save some time $
