CPU overheats close to 100 celsius in 8750h when cpu only works 30 percent

Do what egydiocoelho is saying and use Throttle Stop but and tell us, is your Aspire A715 72G 79R9 under warranty? If it is then consult your Acer Service center and get them to fix the problem, if its not then, open the case and inspect the CPU/GPU and if the fans are not clogged with dust and how the paste condition is? If its not dried out, thin or not covering the core of the CPU/GPU or the other thing that you said "the tape that was on the cpu that company didn't remove that from the cpu"

Btw, repaste both CPU/GPU with a top quality paste, for example, the Thermal Grizzly - Hydronaut paste which has an excellent thermal conductivity, but it was created specifically for users who are looking for a quality product with an excellent performance and heat dispersion and protection, for example, a system that is susceptible to high heat and gaming. Also, you can buy a top end "Tablet Laptop Cooler" (which I'm using and they are excellent to a certain level) as they do lower temps by at least 10c and boost the cross flow ventilation of the case! There are more extreme mods that you can do to the case of the Aspire A715 72G 79R9 as your case is not really that well ventilated and has an inadequate venting slots to dissipate the tremendous heat that the Aspire A715 72G 79R9 generates but, that is a different thing and needs expertise to do that and experience of disassembly and build qualities. Which is not recommended for the novice user! 

Ashlanjld I understand all that your concerns are but, your CPU could have these problems:

a) The CPU is faulty because of continually being overheated (which is a very unlikely thing) and you can do an online “CPU Stress Test Online” or you can do another CPU test called "Prime95" which you can download here: https://www.majorgeeks.com/files/details/prime95.html

This is what you do to test with “CPU Stress Test Online”:

1. Go here: https://cpux.net/cpu-benchmark-online?vsid=l2v7w and put your CPU model e.g. i7-6700K etc

2. Start CPU Test

3. Wait (5 min) until the test is over which will analyze your CPU and give you a "Testing results for your CPU" e.g. Rank, Score and Speed

4. Then, go to "CPU Benchmark" and compere your CPU to compare it to a normal CPU ofyour model and consider these results for informational results.

(b) If its overheating because “my cpu works 14% with close 90 degree at first 10 minute” which should not be happening on your Aspire A715 72G 79R9 as there could be repasting and fan dirt obstructing their normal operation.

Now and in saying all of the above, your CPU when the laptop is turned on and working normally (not in gaming) should be at a normal 60c to max 70c and in gaming and extreme gaming it should not exceed 92c or of extensive usage, but and if it does e.g. gets to 95c+ max, the system should turn off automatically, so that you can’t use it and damage either the CPU or GPU.

Repasting (with the paste that I recommended above) and cleaning fans should improve and lower CPU temps by at least and to the normal temps of 60c to 70c normal use and never ever make the CPU go above 92c in gaming or extreme gaming!

To do all this, have a look at what egydiocoelho is suggesting above (even though that is for a Helios 300 which is different to your Aspire A715 72G 79R9 that doesn’t have as good a case ventilation as the Helios 300. Look at the 1 and 2 videos of the things that you need to do a “Repaste” the CPU/GPU in the videos above.

You can do other and more extreme modifications to the case but, you need some expertise as you need to disassemble the whole laptop e.g. take all components out and modify the case with extra vent holes, which is a big job and you need experience, which you don’t have and I wouldn’t recommend it. Do the “Repaste and Fan Clean” and get a good Laptop Tablet Cooler” as that will lower temps to below your high temps, that you have, if your CPU is not damaged, as it will be indicated in and if you do the “CPU Stress Test Online”.
