Choosing the Right Thermopad: Acer Aspire S3 Laptop Cooling System Replacement & Thermal Paste

Hi
I decided to ask this question because I did not find enough information on this topic in both Polish and English-language internet.

Problem: Acer aspire s3 laptop fan started to make noise, I took it out, I cleaned it, turned it, it did not help. You have to buy a new windmill so I bought it.

The heat dissipation system looks as follows, we have thermopad and thermal grease (I do not want to penetrate, which is the process, which card is not relevant to the topic).

I watched a video about replacing the cooling in this paw and the guy does not mention this thermocouple at all. It caused some anxiety on my side, because if you do something, you should do it right. I started a reaserch about theropads and the following questions arose:

1. If I dismantled the system and sits the Thermovolt, should the Thermovolt be replaced or can it be left?
(mine is in such a state that I get better I do not know if it is good or bad, when I watched videos on the replacement of thermopads, sometimes people have a bone petrified)

2. What thermope to choose - there is no specification for this paw so easily found on the net - unless someone knows how to look for such information more professionally - some sites for professionals?

3. If we already think that we need to change the thermosphere and we do not have information about the height, which one should we choose?

4. If we decide to exchange this unfortunate thermopad, can it replace it with something K5-PRO thermal paste? Has anyone used this specific product and what are the opinions, I do not see it to be bought in Poland, so you probably would have to buy through Amazon, unless there are similar products from other brands?


Thanks in advance for your help

Measure the thickness of this thermocouple and use a thermope of the same thickness - pay attention to the thermal conductivity - the higher the better heat dissipation - e.g. 12W / mK are available.

- relevant. If you only have an Intel card - then the second system is a bridge (PCH) - and here the issue of choosing a thermopad looks differently on the GPU. Whether to exchange - it also depends on PCH or GPU - these are completely different systems also in terms of the amount of heat released.

1. If it is not mechanically damaged / crumbling leave it
2. About the highest thermal conductivity expressed in - lambda
3. You use something like this, it adapts as needed



are high-class thermocouples also used originally in laptops "Laird Technologies T-flex 760 Thermal PAD Wärmeleitpad GPU"

You can use aluminum or copper plates under certain circumstances but at your own risk - chipping the core with very uneven heat sink

4. I finished the experiments after spending a few hundred on different thermocades and I didn't test or intend to test any glues, it costs half as much as the MX-2 paste, a waste of money for me but you can try and share the test results.

And you have everything in this topic. I will only add the obvious, but not to everyone, that you measure the thickness of the thermopad in a place where it is not crushed.
Generally, if it is whole, not crushed, hardened then you can leave it. Replace only the thermal grease.

Thanks to everyone for your help.

The plan for now is to replace the paste with a new artcit mx-4 and test the temperatures. From what I was able to find, the thermopad is on the processor, paste on the card. The computer comes a bit with this old thermocouple and if it is too warm (the question is what to refer to , I think that I will pay attention to the continuous operation of the windmill, it seems to me that once on a small load it did not turn on at all, at the end it has already ridden all the time) I will also mention thermopad.

I still have a question for you about the height of the thermocouple, it is difficult to determine exactly what the height of the gap is based on the current crushed thermocouple. It is true that I found on the forums that some recommend measuring the gap with a feeler gauge (to make it funny my father has a miracle ), but in this case I don't even have a way to approach it.

Based on the fact that this crushed thermopolar is less than 0.5mm and how I look at the specifications of the thermopads, here are the specific companies from aab cooling:
- 1mm month ensures heat dissipation for the gap from 0.25 to 0.5mm
- 0.5 mm tread provides drainage for slots from 0.1 to 0.4mm

which thermograph to choose is best to have incomplete information about the actual size of the gap. From what I see, these thermopads are most often in the heights of 0.1, 0.3, 0.5, 1, 1.5, 2, ..., I hesitate between 0.5 and 1mm, what do you think will be a better choice?

Again...
I haven't seen the Aspire S3 board with graphics.
You probably have the HM2-CR UMA MB disc - check google.pl how it looks and compare.

Square system with SLJ8E or SLJ8C designation - this is the PCH bridge. It does not require special cooling - you can leave the old thermoplan (especially if it does not crumble and "sticks").
The second system - the rectangular one - is the processor and the graphic system in one - there should be paste on it and do not save here - the MX-4 will be good - the performance depends on it (e.g. limiting the timing) and replacement in the event of damage is expensive.

Exactly.
You would like to replace the Mushroom thermosphere, then take 1mm
But there is no need.
Pasta by all means Ok.
For this thorough cleaning of the fan and heat sink.
