Overheating laptop - I cleaned the fans... Suggestions? - Page 2

post #11 of 21

Well, it's possible to undervolt any computer/laptop, however as TG_bigboss stated the stability tests can be troublesome as it'll most likely shut down before it can finish the tests.

I'll disassemble the laptop again tonight and try to re apply the thermal paste again. So is it possible that a laptop has two separate CPUs? I'm thinking of wiping the substance off from the secondary green CPU-looking like chip and applying some thermal paste on that too.

The other CPU is either the IGP or the Northbridge. However, the IGP does get really hot as well so you'll want to reapply there as well.

Yes.. that makes a lot more sense, it being a GPU haha. Forgive my lack of knowledge on this subject.

On another note... I just disassembled the laptop again. After using rubbing alcohol to completely remove the thermal paste, I reapplied it to both the CPU and GPU.

Unfortunately, after assembling it together the same thing happens and it boots up at a ridiculous temperature.

Any other ideas?

If he's on Vista or 7...

Go to Power Settings, Change Plan Settings (put him on Balanced if he's not on it already), Change Advanced Power Settings

Then, Processor Power State, then Maximum Processor State

It'll be on 100% probably. Knock it down to about 95%.

Shaved 20c off my HP dv6's idle and load temps, with no noticeable drop in performance. Also stopped it shutting off due to overheating. For some reason this also brought GPU temps down.

What GPU does he have? there might be power saving options in its controls, try using those too. Less power = less heat.

If he's on XP I don't know how to get to that menu.

Very good idea! Even though i dont need it now. might be usefull in the future

wow i mighty try that on my friends laptop and see if that reduces the heat a lot lol thanks

My dv6 idled at about 70c beforehand, and hit 90c at load. It overheated at 94c and froze.

I've got 8 tabs open in Chrome, MSN, and iTunes open, and the cores are at 56c, and the board says 60c.

That is a fantastic idea! I ended up setting his processor state to 90%.. Allowing it to max at around 95C. I then undervolted it a little as well (it was lousy) to make it max at around 91-92C. The main concern was that it overheated until it shut down, so as long as it doesn't do the latter it's good.

Thanks everyone!
