Windows 7: CPU running at extremely high temperatures

CPU running at extremely high temperatures

Over the past few days I noticed my laptop was cranking out a decent amount of heat. I checked the cpu temp in Speccy and when only running Firefox the cpu was between 90C-97C. I'm sure the cpu should not be running this hot when simply surfing the internet. Even when idle the temp hovers around 80C. I ran a full system scan in Norton and came up dry in viruses. Same result in MalwareBytes. I'm not sure what's causing this. Any suggestions?

Sounds like either you have dust bunnies plugging up the CPU intake, or the CPU fan is not working properly.

A can of compressed air may help remove the blockage if that is the problem.

Can you feel/hear the fan running and speed up as the CPU heats up?

ya, try to take apart your laptop and clean all the dust. also go into task manager then click "show all processes" and then click the cpu usage tb at the top so it orders from highest to lowest. from there you can see what process is using the most amount of cpu

If the problems ends up being blockage. YouTube has disassembly videos to help you clean out the CPU vents and fan of your Asus UL80Jt Notebook.

I can definitely hear the fan running it gets fairly loud. I will try to clean the dust out and see if that works. When I first boot up my computer after being off all night, it idles at around 60C but as I start to do things like boot up iTunes or run a program, the temp spikes and stays up even after I close all the programs and just let the computer sit. This happens with the CPU usage staying under 50% the majority of the time.

I wonder if the thermal paste is playing a part.

i3 in reality isn't that old to have it's paste failing but I would blow out and clean the lappy first and then torture test then if needed you can re-apply the paste.

I would stay away from torture testing until you have the temps down, it's being tortured. Have you been using the lappy on your lap, cushion or bed? Always use it on a hard surface to avoid blocking the cooling vents.

I'd agree age wouldn't play a part but a bad application could start to break down in a much shorter time than would normally be expected. It's rare but I have seen it happen once or twice.

In Task Manager, does the CPU idle about zero to five percent, when not in use?

Once the heating issue is resolved. You might even consider investing in a Laptop Cooling Pad.
