'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.'

Could you please reply to my final five points? I have repeated my reply since I am expecting you have not received a notification

1- As log as the alcohol will evaporate and dry quickly, water takes a longer time to evaporate and dry, I can use any alcohol some people use for drink?

No you can not, most alcohol used for human consumption does not have enough alcohol by percentage. You would need a least 190 Proof drinking alcohol.

2- I should apply 4 small beads on the half way of each edge as in the screen shot below:(what you mean with  'a square' in  'about half way to each edge'? 


  <-----  4 corners like this example.

3- I don't need to  roll  the thermal compound beads onto the surface of CPU to be smother?

NO don't roll, the compound will be spread evenly across the CPU when you securely mount the heat sink and fan assembly.

4- In my case, GPU is surrounded by pads, so I will only apply one bead of thermal compound of the center of GPU? If that is what you think is best, yes one bead.

5- how big is each bead of thermal compound?

About the size of a grain of rice. With a slightly larger bead in the center.

Sorry for the slow reply, but the forum has had significant problems over the last day and a half.

This is the screen shot of CPU, so you think I should apply new thermal compound as in blue colour.



If the gray colored mater on the CPU is the remains of the old / original thermal paste it must be removed before you apply the new thermal paste. If you fail to remove it then the new thermal paste will be on top of the old thermal paste and will not be effective in transferring the heat from the CPU to the Heat sink / cooling system. End result is the CPU will run too hot.

Your CPU temperatures are way to hot !  Normal at idle should be 40C or less and under load about 60 to 70C.

I have purchased a new fan/ heat sink Assembly from eBay, and unfortunately the heat sink was not fitted to my motherbooard.(i.e. it wasn't mounted to the CPU and GPU). However, only the fan was similar to my old fan. So, I took out(removed) my old fan from my old heat sink, and after taking  the new fan from my new heat sink, I installed the new fan in-place my old heat sink very well.

Then, I used a material including alcohol(I was told that it has 100% of alcohol). I used a clean tight cloths to apply some of alcohol to remove the old thermal compound from the CUP, and GPU, and the contact surfaces to CPU and GPU. Then, I let the CPU and GPU to dry. After that, I apply new thermal Compound of my same thermal compound which is not sliver with following your way to apply the new thermal compound.

While my computer is in load(not Idell) (about three streaming videos are playing on Youtube.com, and two videos stored on my HDD are played by Media players installed on my PC.   However, although the error "'The system didn't detect that a cooling fan is operating correctly'" is no longer appearing to me, the CPU and GPU temperatures, I think according to the screen shots below, are still way to hot. The fan is well blowing out hot air from the events

These are the screen sthos were taken from time to time but in about the same load

By the way, the new fan/heat sink NOT suitable to be in-place my old fan/heat sink was applied with a thermal compound by vendor. Is it reasonable?
