Quick update on this. I had a quick look at taking the heatsink/CPU out today but I think its gona be a big job! 

 

Theres a little back panel that comes off for RAM and HD access, but the rest is all a one piece cover with about 15 screws holding it on. I can imagine even once there out it won't just lift off like I want it to and will have half the laptop attached to it still. So I think i'll left that for now

 

 

 

However, I got the hoover out and vacuumed all around the ram and HD (little bit dusty in there) and then vacuumed all the vents and the heatsink just holding the hoover over all the vent holes. 

 

This seems to have helped it a bit actually, but maybe because its just not as hot/humid weather today. 

 

Either way i've had Realtemp running again and I can't get the temp over 82 degrees today even if I try. I played 5 1080p videos on top of eachother before and although the CPU was at 100% load, temps never got over 82, and now average around 55-65. 

 

So basically, just after a quick hoover its drop about 10 degrees on average :)

2nd the above.. you will probably find a carpet of dust stuck on the heatsink.. go steady with the compressed air as it can damage the fan as it spins it at a higher speed than normal..

I recommend stickin something to hold the fan still while push compressed air through it..(cocktail stick generally does the job, an make sure the laptop is off)

The above may help but 90% of the time they neec stripping and cleaning and replacement of the thermal material that sits between the processor and the heatsink (manufactuers generally use crap thermal pads/paste. If you do strip it get some decent thermal paste (arctic silver is pretty good) and remove the old paste before applying the new stuff..

Enjoy!

Yeah i agree changing thermal paste is probably best solution and cleaning vents in heat sink. Laptops are just not design for the lap which is stupid its amazing how many manufacturers put the processor heat exhaust at the bottom I've had many a gaming night with a massive red mark on my leg from my old laptop.

I repair and refurbish laptops and the most common cause of overheating is lint and fluff  blocking the way for the air to circulate. Also the thermal compound will dry out overtime and become next to useless. I use a high quality gold thermal compound on my jobs and it is very good.

 

Don't be afraid to carefully take it apart and do this job but if you are new to this then just take your time. Toshiba Laptops have a key to the screws. you will see a letter followed by a number next to each screw hole i.e F3  F4 etc, the higher the number the longer the screw. Just make sure you put the screws into separate piles labelled with the corresponding F's

Once inside, its just a case of unscrewing the heatsink clamp from over the processor, cleaning of the old thermal paste and applying a fairly thin smear of new thermal paste before refitting. Also you can dismantle the fan and thoroughly clean while you are there.

 

If you don't fancy this then remove the Hard drive (for security purposes) and send it for a service. Usually cost from £25 upwards. I do full services all inclusive for £35 so I recon it would be around that sort of price or perhaps im just cheap!

 

Best of luck

Its worth having an attempt yourself stripping the case off, it's pretty easy.

 

Just make sure you take photos as you go of any connections and label where the screws went.

ideally take it apart, clean and replace the heatsink to cpu compound with something decent as the standard manuf stuff is terrible.
