The GPU fan has failed on this laptop, so all the blowing out/repasting in the world wont make a significant enough difference, until I get time to pull it apart and find the Dell part no. for that fan. Even then, it's falling apart anyway (I will bring it to Cyberlegends 2, so people can have a good laugh), so Ive decided to move on.
It's now just a case of transferring the data to my current laptop. (Think Exxos' post about installing Linux and you will get a similar picture of how that went on the current laptop; As my new current machine is quite an old laptop too, even lower spec than the overheating one, I was looking at a really 'low system requirement' distro, so went for Q4OS, which is fast enough, but does have some quirks that I need to iron out).
On top of that, this particular Dell laptop model was what I believe to be pushed past a safe working thermal limit (due to the fairly good GPU at that time). Most of the laptops we purchased from Dell; high/mid/low end Inspirons, lattitudes, XPS and even Alienware (I would estimate around 90% of the incoming laptops) with thermal problems could just have the board, fan and airways blown out and a die clean and reapplication of a good thermal paste...job done. (Another 5% maybe would need Coca Cola/pet hair/smoke tar/etc cleaning off the keyboard and wherever it had progressed to on the mainboard, or air inlets and ventilation/cooling system accordingly).
However, this particular model was always a pain and even with the above procedure, required several careful attempts to get it 'good enough' so as not to overheat and have thermal cutouts.
Even units out of the factory would fail at a fairly high rate, if the weather was too hot and/or lack of ventilation room.
Probably not the best 'daily driver' laptop really, but it was a very well specced one when I carefully serviced the thermal system, got it working well and took it home.
If you are wondering, it's an Inspiron 7720. (I'm already missing the FHD screen! Ive downgraded to an i3 3rd gen Acer with a 1366x768 screen
