RNP 6 w/ Xeon CPU and upgraded fans

[walshlink]

Changes made to keep RNP 6 cool after upgrading to Xeon CPU:

OS: 6.4.2 Beta 1

Installed/Modified:

Delta 80x15mm PWM EFC0812DB, 48.8 CFM, 3800 RPM, 41 dBA
Noctua 120x25mm 3-pin NF-F12 Industrial PPC-2000, 71.5 CFM, 2000 rpm, 29.7 dBA

Ran the following command from SSH:
# echo 2000 > /etc/frontview/min_fan_speed_override

Reversed CPU fan to suck air in

Removed plastic film between CPU/MB compartment and System Fan compartment

Results:

No CPU load
- CPU Temp - 35C
- CPU Fan RPM - 1600
- System Temp - 46C
- System Fan RPM - 2000

CPU load after 10 mins (scrubbing volume)
- CPU Temp - 57C
- CPU Fan RPM - 1600
- System Temp - 50C
- System Fan RPM - 2000

I thought the cpu fan is originally set up to be blowing from outside towards the heatsink

[walshlink]

Probably was...when I upgraded fans, I probably eff'd it up...so yes, blow/suck air IN...

Hi guys...

If i only want to speed up system fan minimum rpm's? Is that possible?

You could run the echo command walshlink mentioned earlier in the thread or a similar one. His example sets the minimum fan speed to 2000 RPM.

Hi mdgm,

But that will set both fans to minimum 2000 then?

My cpu temp is good but my system temp is a bit high. So i just want to raise that abit.

That is just an example. You could set it to e.g. 1200 if you prefer. The value you choose must be higher than the default and a realistic value.

🙂  I get that mdgm...  😄

But my question is: can i set cpu fan to one minimum value AND system fan to another?

I'm not sure if that min fan speed applies to both fans or not.

Our current desktop systems have one fan, I believe.

[walshlink]

It appears to me to only be applied to the System fan, not to the CPU fan. I would like to set a threshold for my CPU fan as well. Also, I have noticed CPU temps can get up to 60C before CPU fan starts ramping up. Is that normal? I wished it started ramping up at much lower temps.

You can make your own custom sensors file if you want to do more advanced changes to settings.

The fans will spin up when needed. Though of course if you use a 3rd party CPU then a custom sensors file may be a good idea to have settings tailored to what works well with that CPU. Our sensors files would be designed for stock hardware.

mdgm,

Are you talking about modifying the system.conf under sensors.d?
