AMD Wraith Cooler performance under Prime95 : CPU temp (orange), GPU temp(green) DRP4 under Prime95: Temperature improvement is very significant! I'm happy! As shown in previous post , here's CPU temp when playing MSFS 2020 with AMD Wraith Cooler: Peak temp is over 90C! Note that CPU has max temp of 95C In comparison, here's CPU temp when playing MSFS 2020 and DUTM with DRP4: Peak temp is below 85C CPU temp when idle (DRP4): When idle, CPU temp between coolers is pretty much the same Another important improvement is Sound Pressure Level (SPL). Based on readings, SPL is lower by 5-6dB when DRP4 fans are at max rpm. That's major! My post on SPL with AMD cooler and CPU at high-performance mode.

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...
