Hey all,
I just wanted to share this. I had the problem - waking my PC up from standby mode - that the CPU fan is obnoxious loud, but I happened to realize it went normal after a high CPU load (compiling a big source tree via make -j 4 e.g.).
So I guess the "CPU Fan State" is somehow lost after stand by and it will first reset after a state change (warmer = recalibrate). To force this, there is a nice tool called stress:
Install it: apt-get install stress
Help: stress --help
`stress' imposes certain types of compute stress on your system
Usage: stress [OPTION [ARG]] ...
-?, --help show this help statement
--version show version statement
-v, --verbose be verbose
-q, --quiet be quiet
-n, --dry-run show what would have been done
-t, --timeout N timeout after N seconds
--backoff N wait factor of N microseconds before work starts
-c, --cpu N spawn N workers spinning on sqrt()
-i, --io N spawn N workers spinning on sync()
-m, --vm N spawn N workers spinning on malloc()/free()
--vm-bytes B malloc B bytes per vm worker (default is 256MB)
--vm-stride B touch a byte every B bytes (default is 4096)
--vm-hang N sleep N secs before free (default none, 0 is inf)
--vm-keep redirty memory instead of freeing and reallocating
-d, --hdd N spawn N workers spinning on write()/unlink()
--hdd-bytes B write B bytes per hdd worker (default is 1GB)
Example: stress --cpu 8 --io 4 --vm 2 --vm-bytes 128M --timeout 10s
Note: Numbers may be suffixed with s,m,h,d,y (time) or B,K,M,G (size).
And finally run it only with high CPU load: stress --cpu 4
In htop I see 4 processes running at 100%, after a few seconds the CPU Fan is recalibrating and near impossible to hear, thanks to Arctic Cooler. :D
Hardware info:
Mainboard: FM2A68M-HD+
CPU: AMD A8-7600 Radeon R7

I wonder if Linux is the problem or my hardware tho. I kinda tend to Linux problem, because I never experienced it via Windows. I installed all kinds of CPU fan sensor tools, but nothing even recognizes a fan.
