RNDP6310-100NAS How to increase the minimum system fan speed
I have a ReadyNAS Pro Business edition (2008 edition) with 8GB RAM and 6x6tB drives installed. Just upgraded the CPU to E7600 with no issues.
Even before I upgraded the CPU, the system temperature hovered in the high fifties (deg C), which is borderline high temp. In addition, the system fan runs typically between 800 and 950 rpm to maintain this temperature. When I press the recalibrate button for the system fan, the system temperature drops by up to 6 deg C (from 59C to 53C) which is where I'd prefer it to be. I believe I read on this forum there is a way to specify a minimum rpm for the system fan, and I'd like to do that to achieve a lower system temperature, somewhere in the 50C neighborhood rather than 60C. Any help doing this would be appreciated!
TIA,
David

Cleaning everything ot can help, but I suspected you did that when you replaced the CPU, so didn't mention it.
For me, OS6 seems to do a better job controlling everything than 4.2.x. Have you considered doing that?
This is what works for OS6. Not sure itf it's applcable to 4.2.x:
# echo 1000 > /etc/frontview/min_fan_speed_override
# systemctl restart readynasd

Intel rates the E7600 at 74,1°C, so upper 50's isn't exactly "borderline". Did you use good quality and quantity (not too little, not too much) thermal paste in the CPU install? It will take a bit of time for it to "settle in" and achieve maximum benefit.
I'm afraid I can't help with the fan CPU tweek in OS4.2.x, all my legacy systems are converted to OS6.
Thanks for the quick reply.
My comment is about the system temperature (Temp SYS as reported in FrontView), not the CPU.
So you did say system temperature. You mentioned changing the CPU, and I guess I just glazed over the fact that the temperature was for the system, not the CPU. That is a bit high. But your fan speed should be higher with that reading, I think. It's been a long while since I ran OS4.2.x on anything, but I seem to recall the fan running higher than that at times of high load.. OS6 certainly cranks up the fan much higher at that temperature. I wouldn't expect the CPU (with same TDP as original) or the extra memory to create much additional heat. Have you changed the system fan to a more silent one, as some have?
