'Battery Alert' appears before the 'press 'ESC' key for Start-up menu.', however, ' Cooling Fan Alert' appears after 'press 'ESC' key for Start-up menu.'

Thanks a lot,

I don't think it is a matter of the way of applying thermal compound. So, I am continuing giving the points to avoid the process of  dismantling  my laptop, and then putting it together since this would take much time.

  1- I previously cleaned up my old fan with both a compress air, and with paint thinner, and then have oils it with an Oil  sesame(since I was afraid it got dry due to paint thinner).   So, I put my cooling system assembly together( mount the fan onto the heatsink) 

2- Even if most likely that applying a new thermal compound with the directions you have suggested would help fix the problem, I don't have Isopropyl alcohol- 99% or any alternative to use now in my country. I really live in a country out of commerce.  I asked many doctors about  Isopropyl alcohol- 99%, and they didn't know it.

Some pharmacists said that it is chemical material can be made up/prepared by a request. But, I don't know if they mean with that material with Isopropyl alcohol- 99%. I told them  It's used to kill germs in a cut or scratch.Also used to relieve body aches or pains by rubbing it on your body.

3- What material do you use to clean the old fan? You use Isopropyl alcohol- 99%???

4- While no **motion(notebook is settled well on table, and quarter of its  left-hand side is out of table) ,**If the video on Youtube.com are playing, the the CPU temperature are high, especially when the pages are  active, not minimized. I think. However, when playing videos on my PC not on the browsers online, then the CPU temperature are fairly low.  But, I really  cannot monitor it perfectly since I am human, and not utility designed to do that.

5- My fan sometimes makes loud sound while spinning looks as though it needs oiling?

My questions are:

1- I only found a single fan in the local Yemeni market with $50, and that fan can be boted/mounted into my heatsink well since it is the same size of my old fan. However, I don't know if it would solve the problem or not, and it is sold for $50, if not solve the problem, the the seller will not refund my money since he said it will be compatilbe with my laptop, but if didn't solve the problem, no refund would be. Also, 1- HP store doesn't ship to my country Yemen at all. As a result, I am very stumbled by how to go ahead/proceed? 

Try the fan you have now but reapply the thermal paste as I directed in my previous reply.

2- When playing two Videos on Youtube.com, then the CPU temperatures are very high, although the load is shown about 50% in the core temp. 

Sometimes the CPU temperatures  drop into(shown below), although the same work I was doing on my computer (the videos  are playing at Youtube.com, and the same websites) when taken the first screen shot.

Only thing I can suggest is to carefully monitor the temperature and see if it is specific part of the video that causes the CPU temperature to rise and another part of the video where the temperature drop. It could be the type of action / motion or scenery that causes the temperature fluctuation.

Could you please reply to me to finish this issue forever?

Could you please understand me?

First of all: I have been encountering this problem since December, 2014, and I still don't even find a new fan/heatsink assembly which can be shipped to me.

I don't know where to find thermal silver tape?

Since it does not make any contact with metal on the fan as long as you mount the fan so that it not loose or vibrate you should be ok without the tape.

3- What requirements are needed to replace a fan? I know these requirements below::  

a couple small screws, some copper clips and some thermal silver tape, and **** Isopropyl Alcohol.****

However, What else is involved I don't know?

Since you removed the old fan the mounting of the new fan should involve the same assembly / mounting process only in reverse of when you removed the fan.

Also, What is  cloth or oily film that does not leave any lint ?

Even a well used/worn cotton shirt (White in color) freshly washed should be fine.
