I think you called it on turbo causing the temperature rise. Since limiting CPU to 99% the CPU has stayed mostly below 150°F (never over 170°F), and the fan hasn't spun up too full jet engine mode.
I'll still replace the thermal paste this weekend. I wish I had known about that turbo mode issue years ago lol
No probs, glad you got it worked out.
There are tools to further mess with turbo, but honestly I would not
(It's called "ThrottleStop", and I only had issues after I tried it.)
Undervolting is another option, but I never managed to achieve a stable undervolt on a laptop CPU.
You can mess with it though. Can't hurt. You only need "Intel Extreme Tuning Utility" (aka INTEL XTU).
Basically undervolting reduces the power the CPU can take. But it can get quickly complicated.
Undervolt cannot damage hardware but it can cause some headache.
- On a CPU undervolt, your PC can freeze up completely, or throw a BSOD.
- On a GPU undervolt, your 3D application can crash or get a full freeze.
- Undervolting AMD Ryzen is a pain in the a.. and is just not really worth it to be honest.
Testing is basically the same. You want to test it in full stress, in full idle, and in ALL the other states.
Ie.: It may be so stable while it's doing Prime95 and when its on desktop. But may crash while you just watch Youtube.
So like, save your work often for a while.
a) On laptops, you can undervolt via Intel Extreme Tuning Utility. But the situation is way more complicated.
A mobile CPU has way more power states, "steps" to save power.
So testing them all out will take you a long time.
My 4700HQ could barely do like -20mV which barely meant a few degree.
Some people did manage to do -150mV even.
Start small. You can even google your CPU model, like "4700HQ undervolt" and see values people did.

I would only change the Core Voltage Offset honestly.
b) On desktop with a stable CPU speed and with overclock, you can usually achieve a very stable system.
Like lets' say you have a 4790K CPU and you can push 4.5ghz at 1.2V. It'll be a fast, good, cool setup.
Of course, this is by no means power efficient. But on desktop CPUs, especially on older, non-hybrid Intels, that was not really the goal.
And this all depends on sillicon lottery. Ie.: If you are lucky, your chip will run fast on less voltage.
c) Undervolting a GPU is also always an option (and SHOULD BE used!). It's so good.
So much easier to hit a stable undervolt, and usually it takes barely an hour to figure out a good setting.
Of course in your case, this does not really apply. It only makes sense if you push a card, like playing games on it, running intensive tasks, etc. Even miners undervolt.
