Hello, I tested the SER5 MAX thoroughly and here are my observations:
The lowest noise is in Manual Mode set at "BIOS-->Advanced-->Smart Fan Function". With this, the fan will get locked at a low RPM. Problem is once the CPU hits 93 DEG, the TDP starts reducing from 54 Watts and will stabilise at 40 Watts. So, you now have a slower computer, but it is quieter. [2-Lowest-Noise.png]
The "Automatic" and "Full On Mode" maintain the 54 Watts for quite some time, but drop to 50 Watts occasionally. In "Full On Mode", the fan is spinning at 100% all the time, but there is still a reduction in the TDP, which means the the SER5 actually needed a better cooler like the SER7's vapour chamber.

@tuiguang7, any settings under "AMD CBS" are overridden by the settings in "BIOS-->Advanced-->Smart Fan Function". Set it to whatever there, it would not matter anyway. [4-No-Use.png]
There is a way if you want both silence and performance, that if you don't mind the higher idle temperatures. If you set the fan trigger temperatures high, it will not scream when using low-end applications. It will kick in for demanding applications (including gaming). "FAN Start PWM" can be 80 and above, I set it to 100 since it takes just a few seconds to get there. The noise the SER5 makes is similar to that of a jet turbine. With the PWM at 100, the noise is atleast constant instead of whining up and down. [5-Silent-Rocket.png]
@thdervenis The name of my YouTube channel is ArjunAndVishnu. I have uploaded noise samples in different modes to the channel. In the video, you can check how the Package Temperature and the TDP effect the noise levels. I will post the link in the immediate message.
From what I see, any fan setting will take the SER5 to 93 DEG CENTIGRADE at full load anyway. So, it is up to you to choose whether you sacrifice the TDP for lesser noise, or let it go all out. If the caps on the motherboard are good quality, it will do alright at that temperature. Beelink can answer better if it can handle a sustained temperature of 90+ DEG. Most of the modern computers go obsolete far before they break, and driving them at full speed if often the right thing to do. |
