The LUV server has just been down for a few hours.
It all started a couple of weeks ago when I wrote a Mon plugin for running lm- sensors to monitor system temperature. When I installed that on every system that matters to me I noticed that the hardware that runs the LUV server was reporting a CPU temperature greater than the recommended maximum. It isn't necessarily a bad thing for a CPU to run above the recommended maximum (80C in this case) for a while as long as it is well clear of the critical temperature (in this case 100C) but running 24*7 above the maximum temperature is obviously a bad thing.
I seem to remember a law which relates operating temperature to operating life and reliability (can't remember name). anyway I try to run my CPU's with as little rise above ambient (ie the case temperature) as possible. As mentioned in a previous email I replaced the large heavy heat sink and fan combo; (which uses expletive deleted plastic clips) with an "off-the-shelf"; water-pump and case fan combo.(Corsair H55 Liquid Cooler about $100) The water pump is quite light , sits very close to the CPU and screws direct to the mother-board with decent screws and base plate, thus ensuring a highly reliable thermal connection. On a Asus M4A79XTD_EV M/B with ; 16GB RAM; and AMD Phenom II x4 (4 core) 965 CPU 3.4GHz; I can drive the CPU to 100% on all 4 cores for an hour (doing video conversions :-) ); and not see a CPU temperature rise above 20 deg C above a 'case' temperature of 30 deg C (obviously depends on room temperature) .............best thing since sliced bread ! regards Rohan McLeod
