So I'm a secondary school kid. The local computer sold thermal paste for 5$ but they say they will fix it for me for 80$. I heard from people that its easy but none of the tutorial have any one that supports my model. Im scared <_<

Have a search on youtube for "Acer 4741G teardown".

 

Watch a few of the videos till you feel comfortable. Don't be scared to click on ones with foreign commentary, you don't need to hear what they are saying, just watch.

It's really top price. It's a 1/2 hour job (including getting the coffee and having a chat) for an experienced technician.

 

Just watch the videos, you will see.

Similar model laptops will come apart exactly the same, if you can't see your exact model.

I understand your reticence, I was also unsure the first time I pulled a laptop apart.

 

Things to make sure...

  • get a few containers to keep different size screws in, so you don't lose them.
  • don't force anything, parts come off easily if you are doing it in the right order
  • avoid touching contacts on the mobo with your bare hands.

It really isn't that hard. Like I said... Watch the videos, if you think you can do it after a few watches (you can always work next to another computer and do it step by step, pausing the vid as you go), then do it. If not you can probably find someone who will do it cheaper pretty easily.

No gloves. Im probably gonna take a picture everytime i open a part. Looks to have a lot of parts to open. How do i identify the fan and the thermal place where i place the paste

Put a small pea sized bead of paste in the middle of the the cleaned CPU and place the cleaned fan back on.

I've had the advantage of having being assigned to teach the newer techs how to apply the thermal paste.  After cleaning both mating surfaces(heatsink & CPU) with alcohol, apply an amount equal to what you would get if you just touch the top of the tube.  Then just touch that to either surface(only one). This will leave an amount left on the finger.  Wipe with alcohol.  The chances of contamination are negligible.  Mate the sink to the CPU while the CPU is socketed.  Lock it all down.  Done.

That's not how I was taught. 

 

Would that provide enough paste to cover the surface of the CPU/heatsink?

I actually experimented with different sinks and CPUs.  When properly compressed, it only shows tiny bits of white at the edges.
