Ok I wasn't sure if I would post this thread on the Cooling section or here, you'll understand why.
Notebook Specs (Detailed specs screenshot on the right):
TOSHIBA Satellite A660-042 http://www.newegg.ca/Product/Product.aspx?Item=N82E16834114988CVF
<-- (system summary)
CPU: Intel Core i7 740QM(1.73GHz) http://prntscr.com/16u4hn
some less relevant spec:
GPU: GeForce GTS 350M http://prntscr.com/16u4rb
RAM: 8GB G.Skill DDR3 http://prntscr.com/16u4xx
HDD: 640GB HDD 5400rpm http://prntscr.com/16u53w
Laptop overheat and shutdown after about 5 min of playing any recent game, even when set at lowest settings and resolution. It seems like the heat won't evacuate ..
Games runs flawless, even at medium or high and even Ultra settings and high resolution because the laptop was made for it and has plenty enough power to do so,
BUT it constently shutdown because of overheating, whatever settings I put the game on.
It shutdown at 100°C precisely (which is damn hot)
Everyday usage temperature is around 77°C (which is too hot but not enough to make the laptop shutdown)
[Attempts so far]
-Formated (just purchased from someone and was full of *****ty virus and junkwares)
[Result] :Windows is vanilla Fresh and drivers are all up-to-date. Actually I started to troubleshoot the overheating from there, not before the obviously needed format
-Tried less recent games (Doom 3 and lower) and at lowest settings & resolution
[Result] :Overheating issue persist. It might take a couple minutes more before shuttings down but still doest, and that is abnormal
-Opened and cleaned everything inside the laptop including fan, heatsink.
[Result] :Was all clean already so the culprit is not here.
-Tried the SpeedFan app to force the fan to run faster
[Result] the app won't detect my fan (because of some incompatible bus from what I've read).
Speedfan however made me notice that the GPU temp seems to be fine (here is some temp summary on normal usage (no game) : http://prntscr.com/16u9gb
-Got the thermal paste replaced at some computer shop (he didn't have AS5, but he said they were all pretty much the same.. which sound like bullsh* to me.. anyway.
[Result]: It did lower the everyday usage temp by about 10-15°C but did not fix the In-Game overheating at all. (I disassembled the laptop to verify that thermal paste job and here is what it looked like (no very clean INHO): https://www.dropbox.com/s/42waea6ufqxoym0/2013-05-24%2017.30.02.jpg?v=0mcns
-Went back again to the shop explaining the persisting overheating issue, and he said it must be the CPU that is defect.
[Result]: Made some research about it and seems like it could be it... thats why i'm here now.
[Solution]: Could the heatsink be broke ? (the guy at the shop would told me...)
[Solution]: Could the CPU be the issue ? if so , I can change it since it's not soldered on the mobo and I found the same sold on ebay for around 50 buck. But this lead me to wonder if I could upgrade CPU instead. My research lead me to find a list of compatible CPUs: http://www.cpu-upgrade.com/CPUs/Intel/Core_i7_Mobile/i7-740QM.html

[Solution]: If I can't find the culprit, I will create a custom wood boxed dock kinda like this: http://www.youtube.com/watch?v=t0rYPDXzx5M
[Solution]: Suggestion ?
Okay for now I think you have enough information for a first post. I'll be right here to answer any question you might need to help me solve this issue !
