bowlinraI'm thinking about making another version. This one lighter weight and maybe it will move from the garage in summer to the house in winter. Any thoughts on improvements or anyone else try something like this?
CybieCHow did you setup the fans, are they all in one direction?
notfordmanI run one of these setups open air. In option B unfortunately the CPU's that are closest together draws the warm air extracted into the next chip. A is better only that each cpu is trying to draw in cool air. This is a very cool project.
CybieCit has been 2 months now and it starts collecting a little dust, something I am not happy with I have to clean them every time so I need to "Enclose" them, therefore I Absolutely love what you've done here.
CybieCSomething I failed to do was raise them, I will go do that immediately! If I were to add big fans such as you did would that mess up the airflow from the smaller fans?
bowlinraWhat CPUs do you have, what is your OC and what temps do you have when you run "sudo tpc -temp"?
bowlinraI don't really know if the smallers are mess up the air flow. I tend to think of the rack as a wind tunnel, I want the air to flow as clean as possible from the front thru the rack and out the rear.
bowlinraI run all mine headless, less cables. If those temps are under full load I would be worried at all, some basic flow over and under would be petty. I have some CPUs hitting 60C+, which I feel is too hot. Thou I believe this is a heat sink or tim issues.
CybieCCPU 0 Temp: +31.2Â°C (high = +72.0Â°C, hyst = +67.0Â°C) sensor = thermal diodeCPU 1 Temp: +34.2Â°C (high = +72.0Â°C, hyst = +67.0Â°C) sensor = thermal diodeCPU 2 Temp: +52.5Â°C (high = +72.0Â°C, hyst = +67.0Â°C) sensor = thermal diodeCPU 3 Temp: +37.8Â°C (high = +72.0Â°C, hyst = +67.0Â°C) sensor = thermal diode
CybieCWhile I do most remotely from my workstation I do like to have the ability to psychically access them. The thing I am worried about is summer, it is coming soon here and it has been rather cold, since the room they are in already heats up significantly I wonder what is going to happen when it is 30C (86F) in the room.
bowlinra I missed this earlier.. If CPU 2 isn't running some special load that's not on the other cpus. I'd say you might want to make sure that the CPU Heat sink is working properly, either the fan or the sink is loose, or the thermal paste is too thick or drying up. There is a remote chance the CPU / motherboard temp sensor is broken too.
I really wanted the rack on UPS, but I could easily run >560W per rig. To use a single UPS, I would have had to step up to a 2200 VA system, requiring special 20A circuits, plugs and I'm not sure they even make a 20A extension cord. I really didn't look into that much, probably so have spent more time on it.
