Best way for cooling heatsink or heatsink + fun

Nice, I was just going to use a small copper heat sink.

The ubuntu system on OrangePi plus is only returning 2 CPUs, do you know why?

nproc returns 2.

Even with heatsink, CPU overheats and one or more cores goes off.
Only heatsink with fun ensures full speed cool run.
If the kernel is compiled with CONFIG_SUNXI_BUDGET_COOLING=y option (default), max frequency after some time is limited to 1.2GHz no matter how cool cpu is running.

With heatsink+fun and kernel compiled with CONFIG_SUNXI_BUDGET_COOLING is not set option I was able to get cool operation with all 4 cores on at 1.53 GHz

After 2 days running with average 60% CPU usage (Ubuntu Vivid):
orangepi@OrangePI:~$ nproc
4
orangepi@OrangePI:~$ cat /sys/devices/system/cpu/online
0-3
orangepi@OrangePI:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
1536000
orangepi@OrangePI:~$ cat /sys/class/thermal/thermal_zone0/temp
32
orangepi@OrangePI:~$ cat /sys/class/thermal/thermal_zone1/temp
30
orangepi@OrangePI:~$

nproc
Print the number of processing units available to the current process,
which may be less than the number of online processors

Loboris congratulations for your Images.
I am running Ubuntu on my Orange Pi 2 and it is very very very nice and stable!
The only thing is that I cant change the resolution to 800x480 (as I mentioned in an other post) .

Thank you, do you know if just a heatsink is enough?

I'm guessing I just have to use the other uimage in pararm.sh and rebuild?
