'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.'

I clean my fan using compressed air and remove any remaining dust with a dry cloth (no liquid applied as it may damage the plastic over time)

Thanks a lot,

This means you don't clean up your fan surfaces or blades. If there is hard dust which cannot be removed until it get wet. What material used to let dust be wet.

Can you / are you allowed to purchase Wine or drinking alcohol as a substitute?

Alcoholic drinks are not allowed to be soled, but if I find any, do you think it can be any  alcoholic drink made from Grapes.

I don't think  Isopropyl alcohol- 99%??? can be drinking. 

Fan bearing are usually sealed so oil may reach the bearings but some fan have exposed bearings so a small (very small) drop of light weight oil my work. Take a magnifying glass and see if oil will reach the bearings.

Why do sometimes (even if my notebook is not in a high load, and it is in stable situation on a table) I hear the fan is spinning with a loud sound, however, the air blown out is not as much as the sound comes from the fan while spinning.(I.e. there is loud sound, however, there is a little air blown out) I don't think this is related to the way of thermal compound I applied, however, it is related to that fan might be faulty. You have another view?

The sound coming from my fan looks like the sound of a shaving machine while  shaving.

As long as my fan make a loud sound while spinning, and air blown out is little,  I think that my existing problem with CPU temperatures, and error appearing in the start is related to fan.

Next I use #4 (Thermal Surface Purifier)  and apply a small amount to another Coffee filter to prepare the CPU and heat sink. Then I apply the new thermal paste.

Why have you used a Coffer filter here? I think you can directly apply a small amount( as indicated in your illustration posted before) of thermal compound container/bottle to CPU and heat sink.?

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) 

I clean my fan using compressed air and remove any remaining dust with a dry cloth (no liquid applied as it may damage the plastic over time)

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. 

Can you / are you allowed to purchase Wine or drinking alcohol as a substitute?

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

First I use #1 Coffee filter in my screen shot and apply a small amount of Isopropyl alcohol (#2) to the filter and use it to remove the old thermal paste from both the heat sink and CPU.

The I use #3 (Thermal Material Remover) and apply a small amount to another Coffee filter to remove any remaining thermal past from the CPU and heat sink.

Next I use #4 (Thermal Surface Purifier)  and apply a small amount to another Coffee filter to prepare the CPU and heat sink. Then I apply the new thermal paste.

Items number 3 and 4 in my screen shot were purchased from Amazon, scroll down read the product description as posted on Amazon's web site:http://www.amazon.com/ArctiClean-60ml-Kit-30ml/dp/B0007TOR08/ref=sr_1_1?ie=UTF8&qid=1443896029&sr=8-1&keywords=Thermal+heatsink+cleaner

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.

Could be that the extra loading on the CPU caused by download the video to a temporary folder and file on the disk drive and then reading the contents of the file on the drive (some of which may be buffered in memory). When the buffer is empty more drive and CPU activity take place in order to provide a smooth continuous display of the video.

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

Fan bearing are usually sealed so oil may reach the bearings but some fan have exposed bearings so a small (very small) drop of light weight oil my work. Take a magnifying glass and see if oil will reach the bearings.

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.
