Not saying it can't and doesn't happen on rare occasions.. but nothing like 5-10%.. that would be 1 out of 10 or 1 out of 20 fail.
Failure rate is way below that.. probably less than 0.1% (1 in 1000). Personally this is the first time I've heard of one failing in a laptop.. And only know of 3 desktop failures all 3 because of user error (cutting or lapping them until they leak)
The 'gas' in them is nothing special. The pipes are vacuumed before sealing to lower pressure so liquid will boil into gas at lower temp... yes, same as desktop heatpipe coolers.

It was the heatsink. The Fan was checked and confirmed to be working perfecting. (checked it myself)
Since I replaced both Thermal pad/paste when replacing the Heatsink, I can't guarantee 100% that the culprit was actually a deffect Heatsink. But given all the test I've done so far, I think its safe to say the Heatsink was defect. Actually, the radiator wasn't that hot before . The new heatsink's radiator get much hotter than the old one, which lead me to think the transfert was not done properly on the old HS.

Also I used new TIM brand on relpace (IC Diamond), which is quite thick but seems to do the job fine.

Main thing is you got it cooling properly. thumb.gif
