CPU temp on the rise - Abit BG7

Abit BG7 w/ Intel P4 1.8g about a year old. CPU alarm has never gone off
untill today, during startup(WinXP) the CPU temp alarm will sounds for about
15 secs then stop once the CPU cools. CPU temp reaches about 70C. At idle,
Winbond HD v 2,7 reports 53C CPU and 31C case. As soon as I start a small
program, I can see the temp rise instantly 5 or 6 degrees. I've blown the
dust off everything inside, made sure holes weren't covered on case. Using
stock Intel heatsink and fan. CPU heatsink is cool to the touch.

Any ideas?

almost sounds like the heat sink is not making good contact with the cpu.
Intel stock stuff doesn't use thermal grease that could dry out (for the
cheaper stuff) but just the same, it sort of sounds like the same symptom
that you would get if the heat sink was loosing contact with the cpu core.

if you are sure that the cooling fan is still running at a "normal" RPM by
way of monitoring with something like Motherboard Monitor or similar app,
then you may want to get your hands on some good quality thermal grease and
take the heat sink off, remove the remains of the thermal pad from both cpu
core and heat sink, and then put a thin coating of thermal grease on the cpu
core and mount things back up.

be sure not to scratch the soft heat sink material when you are removing any
remains of the thermal pad. also, pay close attention to the heat sink
mounting to be sure nothing is interfering with the proper seating and
contact of the heat sink to cpu core.

Exactly. Removed CPU and heatsink, found was not making good contact due to
poor installation. Works great now. I guess you should check and see if
your vendor has installed heatsink correctly when you buy board and CPU.

 

re: check heat sink, absolutely. I tend to check it even after a move of
the system, for example, to make sure that nothing jarred the system and
knocked things loose.
