It depends on how Asus has configured the processor. AMD publishes specifications for the processor, but it's up to the system integrator (Asus in this case) to power limit or expand the power budget of the processor in firmware, and chances are, they've throttled down to 5-10w.

 

Clearly, Asus has expectations for who will use this laptop and what they'll use it for: web browsing, word processing, maybe the occasional video conference. For that, you just don't need a ton of power, and trying to suck more power will just cause the entire computer to slow down. Asus doesn't expect this laptop to be a daily driver for enthusiasts. Let's be honest, most people just don't care about whether their processor runs at 70 degrees or 90 degrees; to most people, that's the difference between "oh, that's toasty" and "I'm going to put that on the table because it hurts to put on my lap."

 

If the laptop's a fire hazard, Asus would've recalled it. If it was a deliberate performance kneecap, that would've been evident in reviews by enthusiasts. It if was intentional to save power, then that's by design.

That's a pretty low-power CPU, and the cooling trajectory is pretty clear: it pulls air from the back (near the hinge) and/or from the bottom, blows it across the board (including the processor) and out of the opposite side. The only reason to have a heatpipe would be to carry the heat to some sort of condenser, like a radiator or fin stack, but in this case, there's just no place that would indicate that a radiator or fin stack should be put - such a condenser would almost always be put right at the exhaust of the fan.

 

Tl;dr: don't worry about it.

It's normal for very low power CPUs and electronics. Basically the heat outout is expected to be so low that there's no need to nove the heatsink to the side of the device which allows the heatsink to be bigger. In this case the heatsink is attached to the CPU only.

I amr really confused man,  literally right now I started a Google meet meeting...right after turning on, the HWinfo says the cpu is at 89, and suddenl it says it's ,64...then it keeps wildly jumping between 65 and 85. 

Broken sensor?

 

And @Jurrunio said it's common in low power electronics.. alright, that's sensible but is a 15w chip with 3.5GHz boost and four threads THAT low power?

The fan and heatsink don't need to be 'connected' they just need the airflow to go through the heatsink.

As you can see from the white foam tape the airflow is directed from the fan to the heatsink.

No need for any heatpipes.

Alright, but why the fluctuations tho.?in temperature?as I mentioned In my previous comment?

That can be normal as well. 
The usual way how fans work is, that they will detect a high temperature and start to spin faster. As soon as the temps lower down, the fan will lower down as well until the  temps start to get higher again.
Especially in laptops, where the airflow isnt that great and it highly depends on the surface the laptop is laying on, this can cause such fast fluctuations.

And the lack of a heatpipe means the delay between the CPU getting toasty and the fan actually cooling it down will be slightly higher, as that heatsink will reach capacity much quicker and it will take time for the fresh air as the fan cranks up to reach the CPU.

But like you said, its all been considered in the design.  If its only shooting to 70 it seems like they did a reasonable job on the fan profile, I'd only be concerned if it was shooting up to 90+ when idle.  (although 90C when under load, totally expected)

Mostly because the heatsink is small. That means it absorbs little heat before getting hot.

Retarded heatsink design IMO. No one does that with the CPU
