i9 14900k and Facebook issue

[josedonut]

I find the CPU behaving strangely when I have the Facebook page tab open in the browser. I'm using Chrome.

After a few minutes, the CPU temperature starts to rise and fluctuates around 80°C to 90°C.
Any other pages are ok.

I tried reinstall Chrome without all extensions. But it started doing it again.
I tried Edge, but after some time it started doing it again.
Edge and Chrome both run on Chromium, so I decided to try Firefox. I even formatted my PC just in case. Installed basic stuff like drivers and then Firefox. It worked fine for a few days, but after some time there was a problem there too.

I'm using Asus RoG strix z790-a gaming wifi ii, NZXT KRAKEN 360 AIO cooler.

Latest Asus motherboard BIOS with Intel Default Settings for power limits.
Idle temps are ok. about 40°C. Temps in AAA games are ok too, around 60-80max.

Intel® Processor Diagnostic Tool PASSED.

So everything is ok. But i don't know, what could cause this temperatures in Facebook page.
can there be a feature on the Facebook page that unknowingly uses the processor for its own purposes?

I use some software called QuickCPU64 which is a free download from Coder Bag and is available from here . QuickCPU64 graphs details like CPU temperature and frequency. The graphic below shows what happens in QuickCPU64 when I open Facebook as a tab in Chrome.

The Facebook page is opened at 18:29:36 and as you can see there is a sharp rise in CPU utilisation, frequency and power consumption. Although not on the level you are seeing.

Looks to me that this is a Facebook thing.

I'll see how it behaves in my case.

Thank you.

Hey again,

i ran the QuickCPU and i've got this. The first image was taken when FB tab was open for some time.

Pcores goes almost on 5.7Ghz most of time, power consumption is on 90w and temperature fluctuates around 70-80.

After closing FB tab everything goes to normal. 

On second screen i was just browsing on other pages, watching youtube videos and temperatures was around 40°C (sometimes spikes to 60 when loading page, its normal), half of power consumption etc.

So it must be some kind of script that FB using to causing this. Don't know what for, like mining something for them in background I don't know. Because on my second PC that using 9700k is no that type of behaviour. I know its different type of cpu, half of TDP, lower frequencies etc. 

So i need to find out what script or something causing this and try to disabled or block that but i don't know how

Everything about your PC setup is completely normal. This is an excellent video that explains everything you need to know and describes the behavior of your cpu perfectly.

Thank you for video and i understand all the things. Like it's really beefy CPU trying do staff fast as possible and sometime temperatures goes to the sky. That is what i accepting.

But when i'm idling in windows just with open facebook tab? That is not ok i think. None of other pages do that.

I understand you are focused on the utilization - not so much the temperature of your cpu... The reason you're seeing up to 90 W on a single core is exactly what turbo boost (specifically thermal velocity boost) is designed to do when it detects opportunistic workloads... In other words...the algorithm is constantly, constantly, monitoring and waiting for the right opportunity to boost the frequency (clockspeed). It does this with single threaded, Or multi-threaded (all-core) workloads in order to produce as many clocks cycles ((frequency)), thus completing the calculations in the shortest period of time possible for your cooling solution.

The voltage needed to drive those higher frequencies means more heat output. More heat output, means higher voltage still is needed to sustain the same frequency. AND, yet more voltage, EVEN still, is needed to raise the frequency even higher! So those last few hundred megahertz drives the power level to extreme until it's cut off, because you've either reached the maximum multiplier OR thermal limits of the CPU itself...or your cooler's ability to absorb, i.e. dissipate heat.

If the CPU cooler (yours is a good one) is sufficient enough, weather single threaded, or again, multi-threaded - it will only boost up to the maximum multiplier the CPU is designed to reach. This is also why you will see your frequency drop in an all-core workload, particularly when the CPU reaches PL1 – 125 W power state after 56 seconds of PL2 – 253 W (default).

That is for Intel default Baseline BIOS setting. If you're running Intel default Performance setting, then it is PL2/PL1 = 253 W. And the Intel default Extreme power plan is 320 W for both PL1 & PL2. NOT RECOMMENDED !!! Degradation in the forecast. Those vulnerable Raptor Lake circuits will undergo entropy if too much power—AMPS (current) is drawn through the chip. Any microcode update only controls for voltages and does not change the physical structure of the chip itself. So as long as power levels are controlled within reason, there's no evidence (at this time) any degradation will happen in the meaningful lifetime of your CPU. And, of course, these statements can only be true if it's a new processor with the latest microcode and the correct power plans from day one.



P.S. As to why Facebook NEEDS so much power is something you would need to debug and find out what code is running...to see if any malicious processes... if any at all. Doubtful. Comparing the 9700K vs the 14900K is not Apples to Apples. You've done a good job pointing that out already.
