If the temperature of the sensor rises above 42 degress C (107.6 degrees F), the system logs an error in the Event Log accessible through System Setup. The air entering the customer’s system has exceeded the 42 degrees C standard, and the system must now compensate with increased fan activity and noise.
NOTE: If the system reaches 42 degrees C and logs an error in the BIOS Event Log, it still works properly. The customer should only notice that the fans are louder than normal.
Run the diagnostics on the system to see if any failures come up. To run the diags start the computer and tap the F12 key, select diags from the list.
95 F is not an issue. HWMonitor however is not supported and may show temperatures that are not real. 95C is not possible the system would shut down to prevent damage. Power supply fan can fail and not show any other symptom until it burns up. Power supply should not be hot to the touch from the outside. You didnt say which Size. MT DT SFF USFF.
A day or 2 ago the fan started running high for no apparent reason. The first night it would slow down them speed up for no reason. Now it seems to run on high all the time.
hardware monitor shows 1 core running at 89 degrees and other about 93.
last night when fan was working ok , it was a little higher but not much.
This is a dual core intel..what should the temp normally be. Computer not dusty at all but I blew it out anyway so I am thinking this is a defective fan/sensor.
Thanks
The cpu is at normal temperature.If you want to be on the safe side put new thermal paste on the cpu or if you are wanting to buy a new fan that is compatible
I am not sure what you mean by size? Do you mean the size of the case? It is a slim line desktop and it's the CPU fan that runs all the time...the one that vents out of the front of the case.
A systems guy at work said they had one do this very same thing but they never could figure out why and simply replaced it (He recommended the paste for me).
Is there any other diagnostic software that will tell me why the fan is doing this..ie what it thinks is wrong?

sorrydell,
The operating temperature is listed below.

I ran diagnostics over night but it didn't find anything wrong.
Any ideas on what to try next? A friend says thermal paste.
thanks

35C = 95F
45C = 113F
Tcase on this unit is
72C = 162F
95C = 202F almost as hot as boiling water.

89F degrees and other about 93F which is 32c and 34c
Which is NORMAL in all respects.
89c would be 192F and 93c would be 200F which is almost boiling water.
89c to 93c would not be normal at Idle.
The Question has been answered.
Its never going to be 22c Idle aka room temperature.
Its Passive Cooling not liquid phase change refrigeration.
37c is Body Temperature.
