Question New Build 13700KF with NH-D15S Thermal Throttling @ 100°C

[FUNCTOR]

Hello!

I'm doing my first new build since 2011! Everything was going smoothly until I ran a stress test and saw the temperatures.

Build:
CPU: 13700KF
Cooler: NH-D15S (applied Arctic Silver 5)
Motherboard: Gigabyte Z790 UD AX
Ram: GSkill Trident Z5 64 GB DDR5 6000 CL32
GPU: MSI 3060 Ventus 2x
SSD: 2TB 980 Pro

I updated the bios to the latest version. I set the bios to use the intel memory tuning thing to get the ram to 6000.

In Windows 11, I ran the Intel Extreme Tuning Utility, and rant he CPU stress test for 15 minutes. It takes about 5 minutes, but it eventually gets up to 100°C and I get the thermal throttling warnings.

Idle temp is 36°C.

The primary purpose of this build is to do some intensive data science work that'll be using all cores for prolonged periods of time. I thought I was getting a good cooler to allow for reasonable temps.

At a minimum I want to eliminate that thermal throttling. It'd be nice to get those temps down a lot. I know it's been a while but it used to be high load temps were 50°C.

Any tips or advice would be greatly appreciated!!!
Thanks!

High load temps now days are 89c but that's still not killing it.... You best bet to start is make sure you removed the plastic cover off the CPU cooler that comes on the base of it that sits on the CPU.

I had heard that warning before. There was a relatively big plastic cover on the part that touches the CPU. I removed that. There didn't appear to be a film underneath that plastic cover though.

Are there 2 plastic covers?

Running at 100c. is now a normal thing if the app requires it and the cooler permits.
Many motherboards are set up to run the cpu as fast as possible.
This article on how the 13900K works may explain:

I think it is largely applicable to the 13700K also.

No. There is just the one plastic cover.

The world's best air coolers are no match for a hot running 13700K or 13900K.

Get a large AIO cooler or reduce the core voltage 50 mV or lower the turbo power limits in the BIOS to 200W or to whatever your cooling can manage. Many motherboards default to excessively high voltage and use unlimited power limits. This will overwhelm a top end air cooler and many AIOs too.

Often the plastic cover is a sticker.

CPUs running hot is the new norm nowadays. I would undervolt the CPU and set the power targets to stock PL2, which should be around 250W iirc. So PL1=PL2=250W. You can also set PL1 to stock (125W), too, but that would cost you a bit more performance. However, you can experiment with that as well set PL1 to different values like 200W and see how that goes. If nothing helps, undervolt.
