I did more tests as I just learned that the CPU stock air cooler is set to LOW switch setting by default. CPU stock cooler at default LOW switch setting CPU (orange) / GPU (purple) temperatures: 0:57 to 1:12 - PC at balanced mode 0:20 to 0:57 - PC at high-performance mode 0:02 to 0:20 - PC at high-performance mode with MS Flight Simulator 2020 running Sound pressure level (SPL) at 1m (PC at high-performance mode with MS Flight Simulator 2020 running): Ignore the random peaks as they're from study room door being closed or opened Average around 52dB CPU stock cooler at HIGH switch setting CPU  (orange) /  GPU  (purple) temperatures: Gap around 0:22 to 0:26 is when PC was shutdown for the air cooler switch to be changed to HIGH 0:05 to 0:18 - PC at high-performance mode with MS Flight Simulator 2020 running CPU temperature looks to have reduced by around 2-3C SPL at 1m: 0:00 to 04:30 - still at high-performance mode, PC startup then MS Flight Simulator 2020 running, ave...

Using a miniDSP UMIK-1  calibrated microphone, I recorded sound pressure level (SPL) at 1m away from the PC: Ignore the random peaks. They're from door of the study room being opened and closed. From 0 to 1:30, SPL averages around 46.5dB . Windows 10 power setting at balanced-mode. From 1:30 to 5:30, I loaded and played Deliver Us The Moon game (EPIC settings). Windows 10 power setting at high-performance mode. SPL averages around 51dB . From 5:30 onwards, I closed the game and PC went back to balanced-mode. With this data, I should be able to quantify difference between the stock cooler and new cooler which should be with me next week.

Whenever I play MS Flight Simulator 2020 (Ultra settings) and Deliver Us The Moon (EPIC settings including maxed out Ray Tracing), the motherboard emits a beep from time to time. This happens when CPU temperature reaches 90C and above. As Summer Season is near, I decided to upgrade the CPU cooler from AMD Wraith Prism Cooler to  be quiet! Dark Rock Pro 4 Cooler DRP4 . As of this posting, DRP4 is not in stock anywhere here in Australia so I placed an order today with BHPHOTOVIDEO . It's around A$40 more expensive but at least it's in stock and I don't have to wait for months (if buying locally). I made sure it's compatible to the motherboard: At the moment, CPU is idling at around 48C (Spring Season here in Australia, room has no ACU): Oct 3 6am update: Item has shipped out with DHL Express. Oct 11 9am update: Item somehow is still ‘on hold’ at DHL depot in NJ, USA. Oct 14 7pm update: Finally, some movement! Posting it here for future reference: Oct 16 8pm update: Go...
