I am sure it will not work because I tried everything which are possible and which were suggested by others to me,even other people failed to make it work .If it works in service center, it should work at your home too. After all they are gonna test using your other components.
That's obvious, they won't keep checking if everything works at their end. If you want you can take your speaker and/or headphone with you tomorrow.
Sure you will smoke both your motherboard and cpu and there goes 30k worth components. Unless you're testing your CPU, never ever turn on the pc without cpu heatsink/fan connected.
It's been more than a week now since you removed it from the motherboard. Probably it's dried now. Even if it's not dried, buy some thermal paste. Clean the old paste and apply the new one when assembling.
Oops,I did not know that it will burn my cpu+Mobo and that means there goes few more hundred bucks.should I ask service centre to apply new paste(for free)?wiil it be right?
