I am experiencing occasional system freezes with Esprimo P5915. The system halts completely, so that I need to push the power button for 5 seconds to power off. For example the caps lock is not changing state anymore.
I installed System Guard 3.35 to monitor temperatures and everything is looking fine, temperatures are low and both fans are working (CPU 42C, Sens 1 44C, Sens 2 39C, HDD 42C, PS fan 1080rpm, fan 2 540rpm). However, when I put an thermometer (cheap digital in-out one) sensor to top of motherboard chipset, it shows over 70 degrees Celsius. I guess the chipset heatsink should be larger or there should be a temperature sensor for motherboard chipset, too.
If I enable the "all fans full speed" option on System Guard, the temperature will quickly drop to about 40C, but the system is unusable because of the noise. Is there a way to control the fan speed more precisely, for example setting a minimum speed ?
