Each time I use Paintshop Pro XI and edit a digital picture my cpu sounds off saying it is over heating. Does the same thing when trying to download windows updates.

I have the Intel Perl865 motherboard with Intel 2.8 chip

I use the Intel Active Monitor

01-BGC [CPU Overheating]-5th Feb-2007

Hello BGC – Welcome to – Geeks to Go –

Just a few questions – to obtain a starting point –

(1) What temperature is indicated ?
(2) And what value is the alarm set to sound? – Maybe it is set too critical?
(3) How old is PC?
(4) How long has this been occurring?
(5) What is ambient room temperature?
(6) Does the Monitor Utility give you Fan Speed?
(7) Are all Fans functioning correctly –
(8) Do you have a website for this Intel motherboard? – I cannot seem to locate
(9) What type of PC – Laptop – Desktop – Tower?

Ok – Thanks for the Sensor Report – Here is my study of report -

(1) –

Sensor Name Processor Fan
Current Value 3239
Upper Threshold not applicable
Lower Threshold not applicable


Fan speed does not change much between the temperatures – I would expect higher RPM at the higher Temperatures – 3400 –3500 RPM ??
Do you have the CPU Fan connected to the proper CPU Motherboard Fan Pin Header and is it properly connected??
___________________________________________________________________

(2) –
Sensor Name Processor Zone
Current Value 129
Upper Threshold 156
Lower Threshold not applicable

Current Value of - 129ฐF = 53ฐC – seems rather high – Are you – over-clocking – maybe you should slow down the processor speed for lower temperatures –

Upper Thresold of 156ฐF = 68ฐC - That appears to be reasonable warning value –
____________________________________________________________________

(3) –
Temp goes from norm of 133 to 169
PC is two years old
Happened about 3 times in the last two days
Normal fan speed is 3275
Appears that all fans are functioning properly
This is a dektoop tower
No games played other than Solitaire

133ฐF /(56ฐC) – to - 169ฐF/(76ฐC) is a 10ฐC Temperature Rise – indicates poor cooling control – And playing Solitaire is not very taxing on the CPU – Good cooling should keep < 5ฐC rise Where is CPU Fan Power connected ??

Who installed the CPU – Was there any heat compound paste – applied? Is the Heat Sink properly secured to Motherboard? There may be gaps & hot spots between CPU and Motherboard – which would cause higher temperatures -

Do you have any data from two years ago – when PC was new – to use as a baseline?

Proper Fan rotation should be – Air being forced down into the Heat Sink Assembly and being Forced out the side Fins – Place a thin strip of paper – [1/4 Inch wide] – on top of the fan to check airflow direction.

2 years is about time for the Dust Bunnies to occur – Check the Fan/Heat Sink Assembly for clogging of the Fins – this will block the Airflow – Do a close inspection of this assembly for clogging
_________________________________________________________________

How many Fans do you have in Tower – You should have 2 Exhaust Fans in the Rear – which includes the Power Supply – These should be the larger of all the fans and should be blowing air Out – How many drives do you have – Do you have any front fans mounted? They should be the smaller size – and should be bringing air into the case – Is there a Side Fan – Sometimes this fan can cause – Air Turbulence – and be more harmful than good. Check for neat harnessing of cables – this can obstruct proper airflow -

The problem with using these Utilities – These are generally averaged & not Peak values – and you really don’t know the accuracy for sure –

You can compare these values with your BIOS Values during startup – Go into BIOS & go to –Hardware Monitor Menu – Section – This value is usually a little higher than the Running Temp – because the Fans are set a lower RPM – unless you are not using the Fan Speed Control Feature –

If it gets too hot – The CPU should shut down & this will cause the PC to Freeze – And will require a reset to reboot PC – Does this happen at any time? I would suspect that this should happen when Temp is >76ฐC level – Most Processors die at 80 - 85ฐC range – and most should cutoff/shutdown before –

I do not know what the other zones are – but one should be your motherboard & the other should be Video Card – They seem to be within a good range – 32ฐC and 40ฐC – One thing that can help the video card is keep the 1st expansion slot below Video Card Open – To allow breathing Room for its Fan – and keep cabling away so as not to block airflow – and cause Air Turbulence -
_________________________________________________________________

(1) Try reducing CPU Speed thru BIOS Settings
(2) Inspect for Clogged Fan/Heatsink Assembly
(3) Make sure CPU is secured & Locked properly to Motherboard – Make sure Latch is Locked properly
(4) Make sure Fan is properly secured & Airflow is correct
(5) What is ambient Room Temperature
(6) Is there proper Exhaust Fan action out the rear

Thanks Jack.
I experienced a little trouble with overheating last year and moved the PC out of an enclosure to free standing. It has all the proper fans. THe room temp is 73.

I am going to have my tech make a visit.

Thanks again, BGC
