Laptop Update

[Antoine]

Well as stated. Even if those beeps meant “Processor Failure” if my processor had failed then my laptop wouldnt even turn on let alone boot up to the windows log in screen right?

Also two things for clarification… when applying thermal paste with the dot/pea/rice method does it apply to ALL CPU types? Because I hear that it only works on circular coolers/processors and square ones require a different method to get more coverage.

Also does applying paste also apply to the GPU? Cause everything i watched and read only mentions thermal paste application to CPUs and nothing about GPUs as if ppl dont put paste in GPUs (which i know they indeed do).

Lastly just to clarify im supposed to put a dot of paste on both the cpu AND the heatsink that goes on top of it? Cause everything I read only mentions putting it on the CPU, the heatsink above it will get paste applied when its sitting on top of the newly placed cpu. Soo is that correct?

On further analysis of the OP provided data, the BIOS implementation is not AMI. It is Aptio 4.x
Speccy reports incorrect version.
Aptio 5.x codes are consistent with 4.x. (Not germane, only noted)
See image in OP post https://pchelpforum.net/t/laptop-fan...08/#post-37851

A 5 beep code in the Aptio 4.x UEFI implementation is indicative of a console error. No input or output console detected. A positive PS/2 setting will cause a console present condition whether or not a console is present.
For this error to be valid, one or two of two ribbon cables would have to fail or disconnect. Likelihood approaches zero - OP reports no disassembly.

Aptio 4.x and 5.x reserve space for OEM implementation in all checkpoint ranges.
OP reports a high volume sound which is consistent with legacy AMIBIOS impementations denoting a CPU fan failure.
The evidence suggests an OEM populated field in the reserved DXE or BDS space.
Control is passed to the boot device.

CPU fan failure is the subject of this thread and is consistent with all evidence presented.

Proceed with CPU fan replacement.

Well as stated. Even if those beeps meant “Processor Failure” if my processor had failed then my laptop wouldnt even turn on let alone boot up to the windows log in screen right? INCORRECT. A fried CPU would likely not power on, or would power cycle infinitely.

Also two things for clarification… when applying thermal paste with the dot/pea/rice method does it apply to ALL CPU types? Because I hear that it only works on circular coolers/processors and square ones require a different method to get more coverage. Proceed as instructed. The structure of the CPU remains constant without regard to the shape of the cooling assembly contact plate.

Also does applying paste also apply to the GPU? Cause everything i watched and read only mentions thermal paste application to CPUs and nothing about GPUs as if ppl dont put paste in GPUs (which i know they indeed do). Yes. Apply thermal compound to the GPU cooling assembly. Labor is labor, and I promise you, if there is a cooling plate, there is thermal compound.

Lastly just to clarify im supposed to put a dot of paste on both the cpu AND the heatsink that goes on top of it? Cause everything I read only mentions putting it on the CPU, the heatsink above it will get paste applied when its sitting on top of the newly placed cpu. Soo is that correct? Place the thermal compound on the CPU/GPU. It will distribute itself. If you double up, you create the blanket effect (a bad thing).

[Antman]

The task may seem daunting now. It is actually fairly simple.

It is wise to lay a sheet of foil on your work surface and to remove your shoes and socks. Reduces likelihood of static shock.

[Antman]

And, to clarify -
I omitted some detail in a reply above.

"Well as stated. Even if those beeps meant “Processor Failure” if my processor had failed then my laptop wouldnt even turn on let alone boot up to the windows log in screen right? INCORRECT. A fried CPU would likely not power on, or would power cycle infinitely."

In this context, the POST error ‘Processor Failure’ does not mean the processor is faulty. It means that the CPU may not be properly seated (bent pin or no pin contact) or is not receiving correct power. This particular error can present as a result of a failing power supply. A fried CPU would likely not power on, or would power cycle infinitely.

This does not apply here and is not consistent with ANYTHING reported in this thread or the referenced thread.

Soo no amount of rubbing with both cotton swab or coffee filer and alcohol is getting the paste 100% off my heatsink. I dont even wanna try getting it off the cpu yet if heatsink is this hard (i also hope a few scratches on the heatsink isnt bad)

[DOUGIE]

Avoid scratches on the processor and heatsink at all costs.
Use the end of a plastic ruler, if you have to.
I use either Eucalyptus oil, rubbing alcohol or nail polish remover, with a paper towel.
Looking at the image, the paste looks to have suffered extreme heat, indicating the heatsink wasn’t doing it’s job.
Maybe the heatsink contact was poor.
When you do get the cpu spotlessly clean, look at the processor for heat marks.

[Antoine]

Well as you can see in the pic the heatsink already has scratches, also are you saying that stuff around the edges is burn marks and not still stuck on thermal paste? Also if a cotton swab is causing those scratches you see on the heat sink wouldnt a plastic ruler be worse? I mean its far more abrasive than cotton right?

[DOUGIE]

A cotton swab could not cause those scratches. Impossible.

[Antoine]

A cotton swab could not cause those scratches. Impossible.

Ok then I guess they were already there.. soo even better. I mean seeing small micro scratches on metal is normal right? After all even my cpu which hasnt been touched yet. If light hits it the right way i can make out fine scratches on even it

Btw you say a cotton swab wouldnt cause those scratches. But what about dry thermal paste thats been pushed around on it as its being cleaned? That could be it right?

[Antoine]

ok so I replaced both the CPU and GPU fans, and I cleaned the CPU and CPU heatsinks thermal pastes to the best of my ability then applied new thermal paste. I did nothing to the thermal paste of GPU or GPU heatsink (ill do that at a later date as trying to clean the CPU thermal paste look like 2 hours by itself… I coulda replaced 50 fans in that time lol). Then I started it up to see what happens.

No beeps, Windows failed to load, but a simple restart fixed that. The CPU fan revs up to loud and fast for about 5 secs before going back to normal speed… this happens maybe every 5-15 mins. So it sounds MUCH better, and temps are good. My only worry is I may not have applied enough thermal paste. The dot is used was like no bigger than or barely bigger than a thread or maybe close to a grain of rice. (but Im sure it wasnt even THAT big). I would think something that small even with spreading from the heat wouldnt spread very far. But the temps are fine so if I didnt use enough wouldnt I know right now, or is that something I wouldnt know until later on down the line when its been like that long enough for problems to develop?

Speaking of temps here are my current ones while idling at the desktop

[Antman]

Good work.

No, dry thermal compound will not scratch copper or aluminum.
Hardness (Mohs scale) Silver, 2.5 | aluminum 2.0 - 2.9 | copper 3.0
Even IF grains of silver the size of those scratches were in the old thermal compound (they were not), those grains would have to abrase the copper first.
It is more likely that an earlier exercise to clean that plate was performed with a metal tool, like a screwdriver.

Point of order:
GPU related heat stress causes substantially more dead laptops than CPU related heat.

Regarding the scratches on the cooling plate -
The plate will likely operate within it’s design standard, but that condition is wholly unacceptable. If I found that on my laptop, somebody would be called to the carpet.

If your budget allows, replace the cooling plate.
If not - and you might enjoy this - NOW is the time to use the credit card smearing technique to apply thermal compound to the scratched cooling plate. Completely fill in those scratches.

You could lap it (grind to a smooth finish), but thermal compound filling the scratch is sufficient to the task.

100% normal

Not normal, especially if idle.

You did not apply sufficient compound. Confirm by removing the cooling plate to see spread.

[DOUGIE]

Well done, Antoine.(y)
Like they say, “Practice makes perfect”

well I left it on overnight just this once to see how things work and the revving every 5-15mins thing has stopped and only happens if I open something labor intensive (like the temp monitoring program or a movie). Also how do we know if I did or didnt use sufficient thermal paste? I mean much lower temps and leaving it on over night didnt make thins hotter. Besides if I remove the heatsink to check the spread and the spread is indeed sufficient wouldnt removing the heatsink break the current pastes seal meaning id have to do the cleaning process all over again?
