Intel Processor Thermal Throttling Issue

Hello Guys! Being new to the forum, this is my first post and a shout out for help. I have just assembled my new desktop and the configuration goes like this Intel Core Ultra 7 265K with 2GB Built in GPU/ Gigabyte Z890 WiFi 7 Motherboard/G-Skill 16GB 6000 Mega Hertz RAM/ Corsair Airflow Fan. Since the time of it's purchase I've been experiencing some serious issue of Thermal Throttling and over heating of the processor, the temperature goes over 100 degrees centigrade.

This happens only when I try to convert or shrink big videos with the file size ranging from 20 to 90 GB. After a few minutes of start of the process the UPS's power button turns red and starts beeping, the cabinet becomes feverishly hot & starts dissipating extra hot air through the vents and eventually shuts down. I tried the power settings by bringing down the strength of the processor to 90% and it works(the temperature keeps fluctuating 50 and 85 degrees centigrade and the PC does not shut down) but then the time consumption goes very high (takes about 14to 16 hours to complete the process).

I've tried different soft wares like, DVDFab, Handbrake, Win Uniconverter, Unifab and so on but unfortunately the result remains the same. My request and query to all the learned people of this forum, is this normal with AI based processors or is there something wrong and a workaround is possible?
 
This sounds very much like overheating. Its not normal for a CPU in a desktop with a properly installed cooler to go over 100C and shutdown.

What heatsink are you using for the CPU? Have you tried reinstalling the cooler with new thermal paste?

@Kaamos_Llama The heatsink is the same that came with the processor. No I haven't tried reinstalling the cooler but if you insist I'll have to call my engineer who had initially installed it to do it again. Also, the problem occurs only while conversion and shrinking of the video files otherwise everything else runs flawlessly. Thanks for your reply.

That processor doesn't come with a cooler so perhaps whatever they used isn't good enough. Suggestions are a 360 AIO or a high quality Air Cooler.

Cooling Requirement: Due to its 20-core architecture and high power consumption (5.5 GHz boost), a powerful third-party cooler is necessary.
