laptop overheating even when idling

[ChristianOutcast]

My laptop core temperature reached 90 degrees even when idling, can somebody help me identify what might be the problem? I scared my laptop would be fried sooner or later.

Your laptop should be about 2 years old now. Is it still under warranty? Anyway, do check if the fan is spinning, and if the fan and heatsink is choked with dust. If you can open it, just try to vacuum it to see if it brings the temps down. Could also be due to dried thermal compound, resulting in poor contact between the CPU and the heatsink.

Better Go clean up the dust inside and replace the thermal paste

Like what ken said, my laptop is at least 2 years old by now, I'm not sure about the thermal paste thing, but my laptop has been having high temperature of 70 degrees even though its idling, but only recently, it reach the high temperature of 90 degrees.

As both of you suggested, the first thing I'll try would be to vacuum the dust out first to see if there's any change before attempting to open up my laptop.

I haven't mention that my laptop is a Fujitsu laptop. I have heard some rumors saying that Fujitsu laptop always have this high core temperature problem, the rumor might be wrong.

Thanks for taking the time to reply to my thread.

The cooling system may be not functioning well.

Notebooks all come with passive and/or active cooling.

Those with active cooling use a system fan that spins to cool depending on the temp. That fan could be defective or weak after months of usage.

It is not normal to see 70 degs at idle. Gotta try to check if the fan is spinning first.

not sure about the active and passive cooling part but, the fan is working fine (without any stutter sound and heat being pass out from the vent)

Yes, it's spinning. I can hear the fan's sound. I have previously tried disabling multicore, hyperthreading and speedstep technology and have also tried disabling process which uses a lot of memories. There is a decrease in temperature but it is only at 70-80 degrees.

Can you feel any hot air coming out of the exhaust vent? It is highly not normal to have your CPU hitting 70 degs onwards at idle, no matter what you did to the settings. All laptop CPU should idle at around 40 to 45 degs. I mentioned all cause I am pretty sure they should not exceed this temp at idle.

Finally, I solved the overheating problem, the problem is mostly contributed by virus/malwareand speedstep technology

Here's what I did, I turn off speedstep technology from bios and find out that there's a decrease in temperature from 90 degrees to 80 to 90 degrees.

After that, I did a virus scan with Microsoft Security Essential, no virus is found, but I'm still not convinced as my cpu usage statistic found in task manager reached a constant 100% and I have ended all process that uses lots of memory but my cpu usage % and laptop temperature shows no difference.

I downloaded quite a few anti virus to confirm that my laptop has no virus. One of which I installed is MalwareBytes. Its the only anti malware/virus that manage to detect something whereas the other antivirus don't. After removing the malware/virus, i restarted my laptop. laptop temperature and cpu usage is normal again

I highly doubt that even if your computer has a virus that it will cause it to overheat... Only programs that can make your stress your computer to that temperature are prime95 or intel burn in...

Like most bros say, it might be a faulty fan or faulty hardware...

Doesn't seem to me that my fan is faulty, but there might be a small possibility that it's malfunctioning. I can still hear my laptop's fan sound turning regardless before or after the overheating issue. Hot air is being passed out of the exhaust vent as per normal.

just found an article which verifies that it is possible for a certain virus/spyware/malware to "overheat" the CPU, not just the cooling fan or ventilation and thermal paste
