What are the turbo ratios set to in the BIOS? What speed do you want your CPU to run at? I think at default settings, 4.8 GHz sounds about right. If you want a 5.0 GHz all core overclock then you need to set all of the turbo ratios to 50 in the BIOS.
What are your turbo power limits set to in the BIOS? The default power limits are not enough for maximum performance. Setting PL1 and PL2 to at least 300W is a good setting. Many enthusiast motherboards allow you to set these to the max, 4095W. This avoids any power limit throttling issues. Your low temps are a good sign that your power limits are set too low.
Use the Windows High Performance power plan if you want your CPU to run at max speed whether idle or fully loaded. If the low power C states are enabled in the BIOS, it is possible to have a fast CPU that does not consume a lot of power when it is idle.
I use ThrottleStop to check or adjust the power limits or turbo ratios.
Post screenshots of the TPL and FIVR windows if you need help with this program. Turn on the Log File option and go play a game. Record your CPU performance for about 15 minutes. Copy and paste the log file data to www.pastebin.com
The default log file location is the ThrottleStop / Logs folder.
Run a consistent test like Cinebench R23. The CPU should maintain a constant speed for the entire test. If the CPU cannot maintain full speed, while the CPU is loaded running Cinebench, open up the Limit Reasons window and look for any boxes in red which indicates the reason for throttling.
If your CPU is reaching 100°C during Cinebench then you will need to either slow your CPU down or reduce the CPU voltage to reduce the heat. Most motherboards use too much voltage at default settings. Reducing the voltage by - 50 mV can make a significant difference to full load temperatures while still being 100% stable.
Don't waste another 32 hours. Post some ThrottleStop screenshots and I will show you how to run your CPU however you like. Use www.imgur.com

If you are running Windows 11, consider disabling Virtualization Based Security including core isolation memory integrity.
Getting frame drops while playing games in Windows 11? VBS might be the reason and here's how you can disable VBS in Windows 11.
Your memory is DDR4-4000. You need to enable XMP in the BIOS so your memory can run at its full rated speed. Post a CPU-Z Memory tab screenshot. DDR4-4000 should run at 2000.0 MHz as reported by CPU-Z.
G.Skill says your memory requires 1.40V so it can run at its rated speed. The XMP BIOS setting should take care of this automatically. If you have any problems, you might need to set the memory voltage manually.
Edit - Try using EVGA Precision X1 for Nvidia GPU tweaking.
Asus has their own GPU Tweak software.
Only tweak one thing at a time. Get the CPU fully sorted out before touching the Nvidia GPU.
