Solved Acer aspire one 722 has a high temperature reading for cpu

Acer Aspire as5315-2826-vhb notebook

Acer aspire one 722 hot cpu
The netbook has cpuid installed and the cpu has a high temperature reading. It is about 58c when idle and is about 65c when you open an application or browse the internet.
The laptop occasionally freezes and also occasionally blue screens followed by shut down.

I have tried using a usb cooling board underneath the laptop which brings the temperature down by about 8c.

Burt surely there must be a fault for it to reach temperatures of 70c which it sometimes does.

Any ideas?

Many thanks. I have changed the settings in the bios to the defaults. I think that I am going to use arctic silver paste on the cpu. It may not be necesary though as I replaced the thermal pad with some new paste 4 days ago and the pc is still running hot but has stopped freezing and crashing. I will continue to use it every day to test it and it seems to be working normally now. I will wait and see though and I am still not happy about the cpu temperature which is about 53c idle. it is more with the power charger connected.

Is the fan working or the fan outlet blocked with dust?

If the CPU temperature is too high there are only a few reasons:

1. Dust, as already mentioned in #1 - check these places:
a. Vents
b. Fans
c. CPU heat sink

2. CPU needs re-seating to heat sink.

3. It has been overclocked.

Always pop back and let us know the outcome - thanks

Blow dust out of vents and openable ports with a can of compressed air. These are available in computer stores, electronic stores, and office supply stores.

Thanks for responses. I have removed and reseated the heatsink and dust isnt an issue. The laptop is only 12 months old and i have removed the small amount of dust that had built up. But it hasnt made a difference.. I have also blasted the air vents with compressed air. But still, the temperature is high.
The fan is kicking in and seems to be working completely as it should. It kicks in when the temperature rises.

The overclocking is a possibility. Can that be reversed.

A friend of mine suggested replacing the thermal paste on the cpu with arctic silver. I may give that a try.

I'm not an expert on overclocking but I'm sure it can reversed if you can prove that is the case and work out what methods have been used. We have a forum for that topic so it could be worth posting it as a specific question.

As for the thermal paste then the best bet is to follow the exact recommendations for your particular CPU - the application method matters too.

Please note that whenever you remove a heat sink: "I have removed and reseated the heatsink", you MUST remove all old thermal compound and reapply the correct amount of new thermal compound. THAT IS your current problem. Please look:

Any quality brand will do just fine, you do not need an expensive one, just the exact correct amount applied in the correct way (not too much, not too little, not spread around which creates air pockets).

To undo overclock settings, just reset your BIOS to defaults, then recheck your settings (CPU, memory, etc), time/date, hard drive boot, and boot order. If you are sure that your OC is not extreme, wait until you reset the heat sink correctly and see if that is enough.

Yes, 53C is a bit on the high side. I assume you have put the case back together because leaving things open can sometime result in incorrect airflow.

Keep us posted.

Did you buy it new? I would return it and ask for a new one. If not,

Can you tell us what program you use to check CPU temp, where you live, and how comfortable you are opening up the computer?

I used coretemp and cpuid to check the cpu temperature. The laptop is not under warranty and therefore cannot be exchanged for a new one. I am in Manchester, UK.

I may have resolved the problem anyway. it has stopped freezing and crashing since I cleaned the cpu surface with isopropyl alcohol and removed the thermal paste. I have since applied a new coating of thermal paste and it seems to have worked. I will continue to use it everyday to test it.

By way of an update. I have been using the laptop every day for the last 10 days and it has not frozen, crashed or blue-screened atall . The new thermal compound seems to have worked. Hope I have not spoken too soon.

Thanks for all responses and help. Will keep you posted
