'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.'

1. The fan needs to be replaced.
2. Both ZP-360 and HC-151 are not sold where I live, so I'm not familiar with either.

I checked with a friend who build computers and he has not heard of either ZP-360 or HC-151 so you need to use your own judgment as which is best to use.

3. then clean both the heat sink and CPU as best you can with a clean cloth to remove the thermal paste. Repeat wiping the metal surfaces several times with a fresh piece of cloth each time until you see no residue on the cloth. Then apply the thermal paste.

Let me know if the new fan solves your problem.

Thanks a lot,

1- This below in bold sometimes happens, I really cannot be able to determine when it happens, although my hard efforts of monitoring my notebook.

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.

2- Have you been familar with The Heatsink Compounds 'ZP-360' ?

Or niether have you been familar with The Heatsink Compounds 'ZP-360', nor you have you been familar with HC-151. You only have been familair withThe paste I use is Thermaltake TG4.

The merchant will pay the HC-151 with $3 for me instead of $5 since there is a rest of amount of $3 for me is left with him. So, he agreed to sell that thermal  me for $3, so do you think it will make difference other than myHeatsink Compounds 'ZP-360'used before ?

3- I was suggest to use medical spirit as a substitute for Isopropyl alcohol- 99%.?

But, I only found medical Spirit which doesn't seem to have any alcohol in it at all as described in its bottle. I don't know if there are other kinds of medical spirit which include alcohol

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.

Water.

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.

Grapes, yes - White colored wine if you can find it.

I don't think  Isopropyl alcohol- 99%??? can be drinking.  No it can not.

Why do sometimes (even if my notebook is not in a high load, and it is in stable situatio

n 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."

Bad bearings can make odd noises.

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.

The fan is defective.

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.?

Coffee filter does not leave any small particle of lint on the surface of the CPU or heat sink which can reduce the effectiveness of the thermal compound. You want the best heat transfer possible.

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)

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

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.

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.

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.
