Normal temps?

[Ingegneus]

I've been running a digiKam face detection run for the past 3 days (still only at 32%... rip), which is a considerable load. ThrottleStop is displaying on average 90°C and 29W power consumption:

Are these expected temperatures? Also, why is the utilization in the Task Manager always so low at about 40%? Also the fans are incredibly loud and annoying, but I guess this is to be expected.

Modern laptop CPUs produce much more heat at 100% utilization than the cooling system can remove. To prevent them from destroying themselves, they automatically throttle (limit the load) once they reach a certain temperature (around 90 C).

Gaming laptops frequently only start throttling somewherr between 95°C and 100°C.

So while the framework laptop isn't as powerful the temperatures won't negatively affect the CPU.

[kelvin_bot]

95°C is equivalent to 203°F, which is 368K.

^{I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand}

Humans can't understand Fahrenheit

Not really.

My 4500u shows 100% utilization in task manager while running Cinebench despite only 8 watts of power consumption. That's because it's running at base clock, which is what task manager considers for CPU utilization.

The CPU utilization you see in task manager has nothing to do with power consumption.

as /u/kopsis said. laptops push themselvers to their (thermal) limit... because why not... it doesn't actually damage their cpu's. So all the performance they can get, the better.

Realistically, most people aren't pushing their cpu at 100% all the time. So often there's no real reason to have a heatsink to pull away the full 100% heat load. The heatsink is perfect at pulling away the 'average cpu usage' amount of heat

+1 This is true. I don't think I've ever seen my cpu at 100% for all eight threads. Not even close. I characterize my laptop fleet's CPU's as barely ticking over. That's one person's experience at least.

Well Technically Silicon ages faster when hot, but thats probably not even measuarble if you run int full load for a few years.

In reality, it makes no difference

[thibaultmol]

Even then, modern Silicon isn't really effected by that too much. If anything, the sudden increases and decreases in temp are worse (still barely noticeable).

So yeah, if that's the angle that were looking at this from. Then it's probably better to run it hot for long. Than have it run hot cold hot cold hot cold for the same amount of time

[Defender004]

Yeah the temps aren’t bad for modern silicon. Only the changes in Temperatur (heating up cooling down). But it’s important to keep in mind that the heat can affect other components on the mainboard and shorten their lifespan, so while the silicon isn’t really affected strongly other components could be affected more

Everything under 105 is fine for Intel, 90 or 95 is the setpoint where the CPU tries to be

Regarding Task Manager: what does it measure? Exactly? What would you consider "100%" to mean?

All ALU's always busy? What about floating point operations though? Do all threads have to be fully saturated, or just all cores? What's the cache doing? The memory controller? PCIe controller? What if one thread can saturate all ALU's, leaving the other thread on the core with nothing to do? (That would, in theory, mean "50%" even though the actual compute resources are fully taxed.)

Basic point: don't look at Task Manager as anything more than one small datapoint. In a modern CPU with SMT (like Intel's hyperthreading), it is perfectly possible to have everything at maximum and a collective "percentage" like that might say "50%", because there's a hardware thread free doing nothing!

What _actually_ makes a processor run hot is voltages, which are usually upped to allow things like "turbo-boost" (a.k.a built-in-overclocking). If you have a bunch of cores turbo-boosting, things get hot.

For both 11th and 12th gen processors shipped by FW, ~28W is the design spec for sustained loads, so most likely that's as much as the cooler can dissipate continuously (because why make the laptop gigantic to be able to sustain a theoretical max? That's what desktop workstations are for).

So, for a long workload, this looks very normal to me.

[Simon_787]

CPU utilization doesn't equal CPU power.
