Acer Aspire 7 thermal throttling

[LM78XX]

I recently bought new Acer Aspire 7 and started testing it, as I have several days to return it to seller if there are any issues. Model is A715-72G (i5-8300H and GTX1050, 15.6" version). Problem is that it thermal throttles during stress tests and gaming. I was reading about throttling on the internet and I have found that it can happen in modern mobile devices, but I have no idea how much throttling is too much. Is it normal for this model, or it has cooling problem and I should return it? Here are some stress testing results (every stress test was running for ~10min):

 

Aida64 FPU stress test, no throttling yet:

 

Aida64 CPU and memory stress test:

 

Aida64 CPU + GPUs, CPU clock drops to around 700MHz sometimes:

 

Furmark + Prime95 in blend mode, it's not as bad as in AIDA test, but it's little bit below base clock:

 

Half of an hour of Wolfenstein II: The New Colossus, high preset 1920x1080, I didn't noticed any lags or anything like that, it was > 40 fps all time:

 

So, is that fine or should I return laptop to seller?

Yes. The cooling solution isn't great

 

If you want to keep it, consider undervolting CPU+GPU and do a repaste

@GeneXiS_X I see you have Legion Y530 with similiar specs. Can I ask you a little favor? Could you run similar tests on your machine and share results (especially AIDA64 'stress everything' with throttling graph)? I am wondering what it looks like on other laptops...

Unfortunately I can't since I got a lemon heatsink (QC issue in short), therefore the result might not be accurate
