Greetings,

I seem to have a problem that started maybe a year ago overheating my HP G7000/7018EP bought somewhere in 2007/08.

Ever since then by searching in google for whatever reason this was happening i learnt a few things like cleaning the fan, replacing thermal paste and so. I managed to open the case and, look what I found.. yeah, dust, dust everywhere. So with a can of compressed air I removed the dust, applied new thermal pad, and so on with the procedues.

I also had this thought that maybe the problem was in the OS itself since it came with that sluggish Vista from factory, I changed to 7 and the overheat just became worse. Even on Linux it's overheating. I also replaced the CPU for a Core2Duo 2.0 Ghz and added a 2Gb DDR2 stick.

Look I don't know what's happening, but the laptop seems to get more hotter than the time when I didn't clean the dust which is pretty ironic.

In that mean time, I could barely use my computer with High Performance even when I was gaming. Now if I do that my computer just shuts down since it's reaching the maximum temperature. (Feel free to correct me if i'm wrong.) So in order to get lower temperatures, I have to set it on Power Saving. But I know that's not a solution at all.

Plus, the fan is almost constantly buzzing (not at the same speed) but whatever it's sound is f***** annoying (sorry for bad language).

So, anybuddy can help with this issue?

Thank you.

EDIT: On windows 7 (Power saving) my idle temps are somewhat like 50-60 C.
EDIT2: Full load temps are something like 90C before the system autoshuts down.

I had the same problem, ran speed fan and found temps @ 85C to94C then shutdown so i tried the following
Strip down and clean out the heatsink and refit with top quality thermal gel , no difference
BIOS update , no difference
To laptop to IT guy at work he ran some tests and found nothing wrong apart from the overtemps
then just before scrapping the laptop i tried a second hand heat sink off E Bay for £5 and it worked a treat now laptop running aronud 45C to 50C underload
the old heatsink looks fine just doesn't conduct heat to the cooling fins
 
HP notebooks have a bit of a history for poor heat dissipation per the design - particularly with the DV series. You said you cleaned it and applied a new thermal pad, but did you apply new thermal compound? What's equally important if you did apply new compound: did you apply it correctly and reseat the heat sink correctly?

Also, if your fan is making an ugly noise, that could be an indication that the bearing is wearing out and perhaps the fan isn't spinning at it's full potential. You can check the RPM of it in your BIOS or in any third party hardware monitoring software, such as HWInfo.
