Intel i9 14th gen heating issues

[Goldyroger]

What is the recommended settings for an Intel i9 14900k paired with MSI B760m gaming plus wifi motherboard?

I've been experiencing heating issues since updating it to the latest BIOS.

Hi Goldyroger,

Thank you for posting in our Community. High temperatures can sometimes be linked to BIOS changes, system configuration, or cooling setup, so let’s go through a few checks together to better isolate the cause.

• Can you confirm the exact BIOS version currently installed?
• After updating, did you load the “Intel Default Settings” or is the system running with custom/auto motherboard settings?
• What are your average idle and load temperatures (please share readings from monitoring software like HWInfo or Intel® XTU)?
• At what workload do the heating issues occur (gaming, stress tests, heavy multitasking, or even idle)?
• Have you noticed any thermal throttling or system shutdowns?

Additionally, if you have done any other tests, please let me know the details so we don't cover the same ground twice.

Have a nice day!

Best regards,

My BIOS version is the latest 7D99vH8.

Intel Default Settings was loaded by default, and I've not changed anything in the settings.

During stress tests, my temps are touching 100 degrees multiple times. Sometimes when I'm just doing my work on my PC, the temperature just climbs to 90+ degrees for no reason while CPU usage is only at 15%.

In my old default BIOS, which was 7D99vH1 I think, my temps never went over 90 degrees even during stress tests. I used to get only 32 to 34000 points in cinebench r23 in this BIOS version, but even after updating the BIOS to the latest version, I get the same points only but with high temps.

I've never had any system crashes or anything, mainly because I don't do any heavy tasks, hell I don't even play games on my PC. It's just the random temperature rises that are worrying me.

In win, try set power plan to balanced.

[Goldyroger]

It is in balanced, never changed it.

Ok. When I again read your posts again I see I made wrong conclusion about your situation.

I think It is normal. Cine res 32000 -> you have cooling capacity maybe about 180W (or less).  It is just simple physical limit for your cooling system and all what you try will be limited with this.  Mine 14900k behaves similarly with good big air cooler. You must upgrade cooling system but not expect miracle. 14th is just how it is. You can try Intel XTU to limit power (put PL1=125W(or 150W), PL2=180W(or less, 160W), you can experiment ) and temperature will be lower and performance will not drop too much in real scenarios. You can try with some undervolting to increase performance (i didn't undervolt because reliability is more important for my using of pc). Limit max clock to 5.4-5.5GHz. Even with all these limitations 14900k is extreme powerful cpu for work (real scenarios, not bench). Single core performance will be great and multicore (beacause of 24 uints) will be very very good. With settings I wrote I don't have any extreme high temp/voltage conditions and fans are always silent and PC is very very fast for many ways of using (common use, simulations, compiling, different types of software...).

Many people wrote about extreme bench performance they get because of undervolting + good cooling + ...  but I think they cpu dying just little slower. Any cooler can't stop generate high thermal energy that caused high temp in sensitive silicon because of thermal capacity, thermal resistance,.... -> degrading is guaranted.

...well, this case is very familiar for Intel 14th Gen CPUs (like the 14900K) especially when paired with newer BIOS updates. What you’re describing (temps spiking into the 90s–100°C range after updating, even at light loads) isn’t unusual but it’s definitely fixable with some tuning since the “latest BIOS” often enforces Intel’s new default power/thermal limits less strictly than before.

Try the following~

• In the MSI BIOS (Advanced → OC → CPU Features):

  • Set Long Duration Power Limit (PL1) = 253W

  • Set Short Duration Power Limit (PL2) = 253W

  • Set Tau (Turbo Time Limit) = 56s

• Some newer BIOS revisions leave PL1/PL2 uncapped which lets the cpu spike far above safe levels. Manually capping them reduces runaway temps with little to no performance loss.

1. Enable “Intel Default” Profile (if not already)

   • MSI recently added “Intel Baseline/Default” option under CPU settings.

   • Make sure that’s selected it enforces Intel’s official spec for power limits.

2. Apply a Negative Core Voltage Offset (Undervolting)

   • In BIOS, under Advanced CPU Settings:

     • Enable “CPU Core Voltage Offset”

     • Start with -0.05V (negative).

   • This often drops temps by 5–10°C without affecting stability.

3. Check Cooling Setup

   • Ensure the liquid cooler or air cooler is mounted properly and thermal paste is evenly applied.

   • A 14900K really benefits from at least a 240mm or 360mm AIO cooler.

     • Run Cinebench R23 or a stress test again.

     • Ideally temps should peak in the 85–95°C range under full load, with idle temps sitting 40–55°C.

I'm using an MSI Mag Coreliquid C360 Liquid CPU Cooler for my CPU and I've attached 2 images of my default BIOS settings after the update. Intel's default setting was already selected after the update and I did not change anything in the settings. Do you guys think I should undervolt this?

[pressed_for_time]

Long Duration Power Limit should be 125W. Some motherboard vendors set it the same as short term but the default is 125W.

Undervolting is not recommended because it carries a significant security risk. If you have a 14th gen processor you could try setting IA CEP Support for 14th from Auto to Disabled.

As someone said you can undervolt -50mV or 75mV max. I don't have overclock mainboard so I don't know what options are available and how it exactly works in all ways/options. Best option will be some version of "adaptive" undervolt which decrease voltage for some percent to actual requested voltage.  My opinion is that undervolt >50mV is too big for example 0.95-1.1V, but ok for voltages above 1.3-1.4V. Maybe someone who did it can help + on net is many themes about it. Undervolt is one of thing (simple and effective), but all about it is more complicate if you detail analysing. LLC is very important, but I'm not sure is it ok to change it if you exactly don't know what you do. For start get HWinfo soft and look for clocks, temps, cores/package power, voltages etc during using your pc. 

As you write all looks normal. Check actual PL1, PL2 limits(max 200W is my opinion). HWinfo can provide info. 14900k create too much heat so just several win process, little browsing,... is enough for quickly heat up cpu for short time and you can see temp peak. It is the price for extreme performance that is not backed by good enough manufacturing technology

PL1, PL2 limit, clock limit up to 5.5GHz and undervolt -50mV-75mV can enough help. 

[Goldyroger]

Guys, I set the Long Duration Power Limit to 125W as suggested by Intel, and now the temp doesn't go above 75 degrees during stress tests.

Intel also recommends 307A ICC Max value, but mine is set at 280A by default. Shall I change this ICC Max, which is called CPU Current Limit in MSI motherboards I think, to 307A?

[Int_user]

Better stay at 280A or 250A.

Try set PL2(Short duration power) to 200W. It will help for decrease short temperature jumps. During normal cpu usage PL2 is important than PL1.

Also, as we already said good practice is limit clock to max 5.7GHz (better is 5.5). Higher clock only increase voltage and  cpu stress with insignificant performance increase.

[pressed_for_time]

Setting  ICC Max to 307A could provide a greater degree of stability. I don't think it will do any harm to set it to that figure. There were issues in the past, now fixed by BIOS updates, where some motherboard vendors were running unlimited ICC Max so an increase to 307A is no big deal.
