Intel i5 14600kf High temperature problem

[TurKLoJeN]

Hello everyone,

I recently bought a gaming PC and chose the Intel i5-14600KF as my processor. However, my CPU is reaching high temperatures. When the system is idle, the temperature stays around 35–40°C. I tested the CPU using Cinebench, OCCT, and AIDA64. At first, it would spike to 100°C within just a few seconds.

Based on a friend’s advice, I changed the CPU Lite Load setting from Mode 22 to Mode 5 and enabled IA CEP Support. Now, during stress tests, the temperature doesn't exceed 85°C.

However, during gaming tests (The Last of Us Part II and Uncharted — all settings maxed out at Ultra, running at 1440p 240Hz), the CPU still reaches 85°C, sometimes 90°C, and in Uncharted, I even saw 99°C.

Are these temperatures considered normal? Or could there be a problem with my CPU?

The PC was assembled by the service team before delivery. After seeing these high temperatures, I contacted a local technician. He said he couldn’t reduce the CPU temperature, and for testing purposes, he tried using an i3-12100F processor with an air (tower-type) cooler, which didn’t exceed 67°C under load.

He told me that 14th-generation Intel processors might have a chronic overheating issue. Is this true?

I’m also sharing photos of my case to show that there are no assembly mistakes and that internal airflow is well-managed.

I have few questions:-

1.) Are you using default boost clocks or is your CPU running manually set clock speed ?

2.) Are you running INTEL DEFAULT settings or Unlimited?

3.) Since you said you have enabled IA CEP after changing Mode 22 to 5, is your PC Stable during heavy gaming?

4.) Did you undervolt your CPU aka did you disable undervolt and using offset in -ve mV?

5.) Are you able to see your AIO coolant temps? if yes what temps they go to during heavy gaming loads?

6.) Why did you chose B760 over Z790 mobo which are optimal for K series processors?

[TurKLoJeN]

I only changed the Lite Load Mode to 5 and enabled IA CEP Support.
Before making these changes, my CPU was reaching 100°C and sometimes my PC would shut down during gaming.
Since applying these settings, I haven’t experienced any shutdown issues.

As for the B760 motherboard, I chose it because the Z790 was more expensive.
I decided to save some budget on the motherboard and instead invested in a better GPU, the RTX 5070.

Aight bud, WHAT am i going to explain in this post, you don't have to do it if you don't want to do it. These are all suggestions which has worked for me on my older MSI B760M Mortar with 13900k.

14th Gen works better with IA CEP disabled for performance.

Lite load mode 5 is very aggressive AC LLC which if i remember correctly is around 0.30 if PC is stable under that during heavy game loads and no reboots or shutdown it's very optimal.

B760s are good motherboard but they are not optimal for K series processors, take it from me when i built my 13900k in Oct 2023, i also bought MSI B760m Mortar mobo as i went all in for 4090 GPU & I regretted it very much because its like i had Ferrari engine but in the Golf GTI car lol.

Couldn't change voltage offset values and many other options to run CPU high Clocks with least voltages and i was unable to see IA CEP options on B760 motherboard for 13th gen.  Replaced my motherboard to Asus Strix z790 and made 2nd pc 13400 on that B760 works fine. I am not saying you should buy z790, i am just stating my experience and fact that z790 are optimal for K series processors.

Since you didn't mention about boost clocks are automatic or Manual. I would suggest you to set 14600k clock speed to 4900 to 5000mhz manually, E-cores can be disabled if you are only gaming and not doing any productivity work like Video editing etc. if you still want to keep E-cores enabled downclock them to 3700mhz (3.7ghz). 

Suggestion (you dont have to do it if u dont want): Keep IA CEP enabled and disable undervolt protection and set the offset to -0.025 & set Lite Load to between 7 to 9 u can also change CPU AC Load Line from 110 (1.10) to 0.50  which is very optimal, just keep DC LLC to default.

Intel Default settings are the settings provided by Intel to mobo makers but it's been noticed that they increase volts and temps for some reason, specially during boost clocks.

Here is with and without undervolt settings:-

No Undervolt:-

P-Core ratio apply mode [ALL CORE]

P-core ratio: 49 or 50 (pick one, 40-50 series GPU are fine with 4.9-5ghz CPU clock)

E-core ratio: 37-38

CPU ratio mode: Dynamic Mode

Ring Ratio: 45

PL1: 125W and PL2: 181W (do not use Unlimited) ICCMAX: 200A (you can access those settings in ADVANCED CPU CONFIG)

Package Power time window: 56 secs

IA CEP enabled

Save and reboot

With Undervolt:-

Microcode Selection: NO UVP

CPU Core Voltage Mode:  - (BY CPU)

CPU Core Voltage Offset:- start with 0.025 and try to reach 0.075 whatever makes it stable. It's crucial to disable UVP for this to work. No need to touch anything like clock speed of P-core or  E-Core
Just make sure PL1, PL2 & ICCMAX values are set as stated above.

Lite Load either choose 8 or 9 or manually set 0.50 AC and leave DC Load Line default (AUTO). Also if you see any option that sayus Intel Adaptive Boost technology Disable it.
