Good afternoon 

 

Since my newest computer is in the shop, I have to use my old Dell which for the past two years when it overheats it turns off.  What could be the cause.  Attached is a snapshot from Speccy.  When temperature starts rising it is sluggish until it turns off.  The vent is flowing good but very hot air.  

 

Thank you.

Your CPU is running at 94°C which is way too hot; you are experiencing auto-shutdowns to prevent damage to the CPU. I assume your Dell is a desktop, not a laptop. You must clean the interior, most likely the CPU heatsink and fan are clogged with dust.

Power down. Remove the side cover and take the unit out on the back porch. Use a small vacuum cleaner with the airflow reversed (aka: blow out, not intake) and a crevice tool to blow out the dust from inside the case. Do not touch the tool to any parts. There will be a large dust cloud, so do not do this in the house. Make sure you clean the CPU heatsink and fan and the case fan(s).

When you finish, take the computer back into the house, power up and make sure all the fans are working. If any have stopped they must be replaced.

After this, if you still are having overheating problems, remove the side cover and run the computer that way. See if your overheating problems stop. If you still have problems, the thermal grease on the CPU must be replaced.

Appears to be notebook...CPU is "mobile" type.

 

Your "old Dell" is probably a laptop in need of dust/dirt removal.  How To Clean Dust.

Thank you for your responses, it is a laptop, and I wont even dare to open it to clean inside. Will try the video on how to clean it.  I have tried the canned air method but has done nothing. 

 

 

Again thank you.

Befor you do that check with other apps to make shoure the temp is relly that high, sometimes one app gets it wrong and you might be able to see your idle temps in the bios.

 

Try with this and see if you get the same heat numbers.
