Laptop CPU heat issue

[redfist]

Hi all,

I've noticed the fan in my laptop has been quite loud recently. I downloaded core temp and when I saw the temp it was sitting at i couldn't believe my eyes. Its 65c at idle!!

Its a compaq with a AMD Sempron SI-42(sable) CPU, being AMD am i correct in thinking that the max is 62c?

Also is it easy for me to re-seat the cooler? to see if that would lower things.

(i've also asked in the laptop section but also thought you guys might be able to help as well)

Looking at the specs below, the max operating temp is 100c, I would check your heatsink for dust build up and see how easy it may be to blast some air in there. Re-seating the cooler is not to bad, but you will need on most cases to dismantle the laptop.

Try blowing the vents out with compressed air first.

I replaced the TIM on my old laptop and the temps dropped massively. It was an easy job if you know your way round a laptop, some of the older laptops have panels on the bottom you can access the CPU though, most new ones require you to dismantle the whole thing though.

Sounds easier than pulling it to bits! will try this first

most new ones require you to dismantle the whole thing though.

Don't know if this is new as its a few years old but this is my second option


Does anyone know of a guide of taking these apart?

Look on google for the model of the laptop followed by teardown guide.

Just take every screw you can see out and mark where they went. JUST DONT FORCE ANYTHING.

As a rough guide for most laptops:

1. Remove the battery.
2. Remove all covers from the underside, pull out any hard drives and wifi cards and ram.
3. Remove all the screws from the underside, place them on a table in the exact locations they came out.
4. Flip laptop over, gently prise off the panel above the keyboard.
5. Lift the keyboard up from the top, take care of the ribbon cable, carefully disconnect it.
6. Remove screws for the hinges of the screen, disconnect the cables and gently pull through the wifi antenna cables as you remove it.
7. Check for any remaining screws or anything that could possibly stop the base coming apart, and finally unclip the two halves of the base, look in side it as you're doing this to make sure no wires are caught or anything.

Dam its a bit more difficult than a normal PC! getting some air this week so hopefully this cools things down a bit. Thanks for the breakdown lets hope i don't need to do it!

To be honest it's not all that bad, more time consuming and a lot more fiddly but there's nothing at all difficult about it
