I've got an Athlon 2000XP running at 1667mhz (not oc'd), Abit KD7 mobo, couple of HDs, bigass copper cooling + fan on the CPU, Leadtek geforce4 ti4200 with Zalman heatpipe cooling, passive cooling on the northbridge, triple casefans (two in, one out), 512RAM, pretty clean interior with clear airflow through the case.
My onboard idle temp was usually between 60c and 65c (all temps are CPU surface readings), which seems a bit high to me. Under load the temp could reach 75 but the CPU would still be stable. While looking for a way to reduce onboard temp I heard somwhere that older Abit BIOSes puts load on the CPU even while it is idle, to reduce the change in temperature between full load and idle states, which would presumably extend the CPU lifetime (less metal fatigue, I guess...)
After updating to a newer BIOS which followed AMDs recommendation to not stress the CPU in this way by adding a "CPU Disconnect Function" to the BIOS, idle temperatures dropped to cirka 40-45c, but I can no longer put any serious workload on the CPU, as it usually hangs around 65-70 degrees.
1. Does anyone have similar problems?
2. Can anyone give me more info on the "CPU Disconnect Function"? I've looked all over for any specs or info but sofar zippo...
Any info greatly appreciated.
