Thermal Paste needs replacement every 6 months or so

I got this laptop before I started University, which I have now completed, three years later. Since then, I've had to reapply the thermal paste at least every six months, if I want to use the laptop for anything else apart from browsing, as it will overheat during any activity whatsoever, even non-demanding games like Faster Than Light.

The laptop: Toshiba Satellite L505-14D 15,6" HD

I should mention that the thermal paste the computer came with dried up within two months, and the paste they then put on when repaired, only lasted about three. When I used a relatively high quality thermal paste myself, it lasts for 6 months or so. Essentially, I'm wondering what to do about this - if anything can be done at all. I don't really have the funds to buy another laptop at this stage, as I want this one to last a couple of years more, at the very least. The problem hasn't really gotten worse since I got it however, it's stayed the same.

So, if any of you can give me any sort of help regarding this issue, that would be fantastic. Also, as I'm out of thermal paste, I was wondering if any of you people could find me some good thermal paste on amazon.co.uk, as a lot of the ones on .com will not be available to me, and I pretty much only choose a random one when I buy my paste.

If you need any other sort of information, do let me know.

Thank you.

PS: I need to reapply it both on the GPU and CPU. Simply posted this here as the CPU seems to be the most dire.

MX-4 is great stuff. It's widely available, affordable, gives good results, is not conductive or capacitive (like Arctic Silver 5), and is easy to apply/clean-off for multiple uses. It also does not require any time to cure.

I am not sure what thermal compound the company was using, or what you were using, that would dry up within six months. Unless it was somehow designed to do that, it sounds like it was either a poor quality product, or you received a bad batch.

I might suggest Artic silver AS5. It does not reach full efficiency until 200 power on/off cycles.
That suggests to me some degree of longevity.

Be careful about applying paste, too much acts as an insulator. It is hard to use too little. A single drop should do it.
Go to the arctic silver web site for a picture description of their process.

I've used MX-4 before, and I'm reasonably sure it's been applied correctly, and in the same amount, as I've had help before from people who work in IT, on different occasions. I suppose it's just a hardware problem that can't be fixed. :(
