CPU Overheating

[GRT8]

For some time my laptop has been shutting down, after a couple of hours or so use, because of overheating.   Yesterday I installed "Core Temp" free program and noted that, prior to shutdown, the CPU temperature was showing temperatures of around 98c.  Late yesterday evening I shut the laptop down as usual and re-started at around 9.30 am this morning.  The first thing I did was open Core Temp. and saw that the CPU was already showing a temperature of 66c.

Now, we have been going through a spell of hot weather recently with afernoon temperatures reaching 30c +.  However I cannot understand why the CPU (AMD V140) should be showing a temperature of 66c a couple of minutes or so after start up when the computer has been switched off for 10 hours or so.

By the way, I have Targus fans under the laptop but I don't think these make much difference to the lapotop temperature.

I use the laptop for email, news and You Tube but not for games.

Could anyone explain the high initial temperature of the CPU please?

The cpu starts working and generating heat just with the work of booting into Windows. If it is not getting enough airflow to cool it or the thermal paste on cpu is old and cracked it will heat up pretty fast.I  would suspect thermal paste first since it gets hot so fast but also probably the vents and fans need cleaning too after all this time if you don't do it regularly. I use a can of compressed air to blow out the vents,ports and other openings at least every 6 months.

You may want to take it to a local computer repair shop and have them clean it and apply new thermal paste to cpu. You can do it yourself if so inclined.

Thanks Cheryl,  I will try the compressed air solution.  I might be wrong but I think CQ56 laptops are not easy to penetrate the inner works apart from the battery, Ram and Hard Drive.
