I've got another new PC for home purpose and decided to make a home server for my sysadmin and programming tasks. Also, my old PC is based on AMD 6-cores phenom and six cores is a good value for virtualization. Are you ready to have a cloud at home? Yes, I'm. I bought a special case (2U size with six places for hard drives. )
This case also has 3 80mm coolers and I hope this a good way to make cold system. Standart PC power supply is placed at a front side and the power cable is going from the front side to the back side.
My Chiftec power supply has a lot of cord and it is impossible to set up all 6 drives inside. It is no place for the power cord. At this moment I think that power supply with unattachable cord is a good choice. I spend one drive case for my cables. Another one issue is a noise of low-cost chinese coolers. They generate a good airstream but noise was unacceptable. I cut red wire and added a resistor (22 Omh) and 33 Omh to another one cooler.
Checking temperature.For receiving temperature linux has sensors application. Installation procedure is a really simple in Debian :
Checking temperature is easy too:
Power Fan has 33 Omh resisitor and speed 1985 RPM, Chassis Fan has 22 Omh resistor and speed 2766 RPM. At this moment I hear CPU fan only. I would like to speed down it by fancontrol. But at this moment I dont known temperatures of my hdd.
Fancontrol has ability check temperature , cooler's speed and make a simple managment using config file. Setting this up has three steps: selecting sensors, creating config file and power fancontrol on.
sensors are detected but pwmconfig reports error. Log above inform that it87 need to be added to modules. But direct module loading failed:
updating /etc/default/grub by next string fixes this issue:
pwmconfig is working ok now:
Turning on fancontrol and checking resultResult of the previous steps is creating /etc/fancontrol config file . Now we can turn on fancontrol and check temperature and cooler's speed.
Not bad for 2 hours work!
