How can I improve my laptop temps besides undervolting with TS?

[AlishaGirl07]

Hello.
I have a -117UV applied to my laptop, however I would like to know if there is any other ways I can improve temps and battery especially when gaming.
I have speed shift set to 150 and sometimes 180 for battery, but it doesn't really help much.
My C state is C8, but is there a way to get it to C9 or 10? I hope I'm right in saying the higher the better, but correct me if I'm wrong though
I have a Helios 300 laptop with i7 10870H and 3080GPU
Many thanks

Intel CPUs are very efficient. Cores will be in the C7 state 99% of the time so the majority of cores are already sitting at 0 MHz. As you discovered, slowing the rest of the CPU down makes very little difference to overall power consumption.

Use the Task Manager and go to the Details tab to check your background tasks.
Eliminate useless tasks and get the idle C0% as low as possible. That is how to save power.

My C state is C8

If you have got C8 working then you are already doing better than most. Some computers use C9 and C10 when in connected standby or modern standby mode. It is extremely rare to see C9 or C10 while you are using a computer. These C states might be limited to laptops with low power U series CPUs and without a Nvidia GPU.

How did you get your temps to below 30DC?
Can you suggest some things to disable, like services I don't need?
I have attached a screenshot of my main TS window.

How did you get your temps to below 30°C?

I have a desktop computer with an AIO cooler and I live in a cold house. Room temperature is usually 18°C.

I do not know what Window services you should disable. I just disable things randomly over many months and I tend to forget what I have disabled. Maybe I should write a guide some day but so far I have not. Open the Task Manager, go to the Details tab and find out what is running on your computer. Most users install software randomly to their computers and never keep track of the impact a program has on the idle C0%. ThrottleStop is very efficient. Some programs and drivers constantly load the CPU when idle when they really do not need to. Writing efficient software is a lost art.

When you check the Power Saver box in ThrottleStop, Windows will switch to the Windows Power Saver power plan. Windows power plans can automatically change the Speed Shift EPP value that the CPU is using. My desktop computer uses an EPP value of 153 when set to Power Saver, 84 when set to Balanced and Windows sets EPP to 0 when using the High Performance power plan.

When using Windows power plans, you do not need to check the Speed Shift EPP box on the main screen of ThrottleStop. Checking the Speed Shift EPP box is telling ThrottleStop to write one value to the CPU's EPP register while Windows will likely be writing a different value to the same EPP register. There is no reason to be doing this. I prefer to let Windows manage the EPP value.

If you're after better battery life, look at screen brightness and wifi rather than CPU, it sounds like you've already picked the low-hanging fruit when it comes to power-savings for the CPU.

If you're after lower temperatures, don't stress it. Laptop CPUs are just fine running hot. If it bothers you (fan noise or whatever) repaste the heatpipes, blow dust out of the fin array on the heatpipes, and make sure the intake vents (often on the bottom of a laptop) are completely unhindered - which usually means propping up the laptop at the back to give it an inch of extra airflow clearance underneath. I 3D-printed a plastic block that adds 15mm of clearance under the back of my laptop and has a well to hold my stylus and a couple of loops to hook my ethernet and power cables in so that they don't fall down the back of the desk when I unplug....
