Why won't my 7530g keep cool?

Hi all,
As the title says, I've got an Acer Aspire 7530g, it's got the AMD Turion X2 system, and it has the geforce hyrbid graphics card.
Seems like it's a common problem with these monsters, but mine is really struggling to keep cool.
I currently have this site, and youtube open, with the laptop on power saver, which is on top of a cooling rack and is idling at 55-65 degrees (Celsius).
If I were to put the laptop into high performance, it'll hit 90 degrees, just on idle. At which point, the entire laptop becomes a substitute for my radiator.

I do enjoy a bit of resource heavy gaming on this system, which pulls my laptop into the high 90s on power saver, and up to 99 in balanced, I actually cannot run it in high performance at this time, because it will overheat and cut out in about 3 minutes.

As I said, it's on a cooling fan, the laptop was also recently cleaned out, and given a service, but this has had very little effect. In fact, the laptop gets so hot, it winds up heating up the fan in my cooling rack, and that blasts very hot air into an already extremely hot laptop.
If you own / owned this laptop, you'll know how small the exhaust is.

I need this laptop to hold out for a while longer before I replace it, I'm pretty sure the aspire only has a 1 year warranty, which this has passed.
Any ideas?

Either your heat exchanger is clogged up with dust or your GPU or CPU has a poor thermal connection to its heatsink. First, with the laptop turned off, blow ait from an air spray can into the outlet vent and look for dust coming out the rest of the laptop. That'll usually clean it up enough to drop the temp quite a bit. If that doesn't work you may need to have a tech check your heatsinks and replace the thermal compound. Or you can try it yourself, but you have to be careful and know a bit about taking apart laptops.

 

I guess I'll have to get someone to look at the heatsinks then, I had the exchanger looked at when I got it serviced, I was told there wasn't much dust in there anyway, nowhere near enough for the system to run at 60 degrees plus anyway
