i9 13900kf High temp and contact issues - help please

Hello, over the past month i've gone through 3 different AIO's and eventually spent $1500 on a custom watercooling loop. No matter what I do the idle temps at around 60w power package is the same at 50celcius. 

 

I've tried every thermal compound that exists including liquid metal, along with every thermal compound application method. I'm using the Asus B660 Rog Strix D4 Wifi motherboard, EVGA 850w 80plus gold PSU, MSI NVIDIA 1660TI GPU. 

 

The custom watercooling loop has 2x 420mm by 60mm radiators with 3x 140mm noctua fans on each, soft tubed to a 4500rpm D5 pump by alphacool with a 150mm res on top. The waterblock is the Thermaltake Pacific W8 nickel plated copper. 

 

This amount of rad space, fan power and pump speed should (according to simulations) have me at an idle temp of 25c. I would assume it must be something to do with my cooling setup, but I've tried 3 AIO's and this custom loop and the idle temp is always 50c on desktop at between 55-60w package power draw.

 

In cinebench R23 I get throttled within 4 minutes and go from a clock speed of 5800 down to 4800. 

Package power spikes at 360w immediately after starting the bench run, temp hits 98 and 99, package power decreases to 260 for 4 min with temps still around 98 to 99c, then throttles to 4800 clock speed at 253package power with max temp of 87c... 

This custom cooling setup should allow me to avoid throttling for more than 4 minutes, right? 

 

Any help is appreciated, I'm wondering if the VRM's of the Asus B660 aren't great and they're somehow impacting CPU temps? Not sure if this is possible, but it is only a 12+1 power connection. 

 

XMP profile is set to XMP1, intel speed boost is active, Asus performance boost disabled in bios. Ram set to 3600mhz. No overclocking or undervolting of the CPU has been done, i'm just trying to run it stock.

prollysatan, Thank you for posting in the Intel® Communities Support.


For this scenario, it is important to mention that the T-junction for the Intel® Core™ i9-13900KF processor is 100°C, any temperature result lower or equal to that value is considered normal and expected:

If you run a bench on a processor it is expected to throttle at some point since you are stressing the processor to a high level. Third-party tools such as "Cinebench R23" might have misreadings and it might be not accurate in the tests done on the unit.


In order to rule out a possible hardware problem with the processor, install and run the Intel® Processor Diagnostic Tool, it does an overall test on the unit and if it passes the test it means it is working properly:

You can also install the Intel® Extreme Tuning Utility in order to monitor the temperature of the processor in real time, it also allows you to run a stress test on the processor:

In the following link, you will find "Overheating Symptoms and Troubleshooting for Intel® Boxed Processors" with additional details on this matter:

Any questions, please let me know.

Hello prollysatan, Since we have not heard back from you, we are closing the case, but if you have any additional questions, please post them on a new thread so we can further assist you with this matter.

 

Additionally, as described on the links above, we also recommend to get in contact with ASUS Support to make sure the latest BIOS version is currently installed on your board:
