There is currently another one on redditinteresting discussion. User jjason82 reports on his high-end Asus notebook and apparentlymassive thermal problems, which now occur after a year of use. Unfortunately, the user doesn't reveal exactly which model it is, but he does provide some information about the features:
- RTX 4090m Graphics
- 96GB RAM
- 10TB storage
Unfortunately, that's not a lot of information, but you can see that jjason82 has probably invested a lot of money in his notebook. As already mentioned, he has the deviceused for a yearand now, according to his information, it is starting to overheat. Unfortunately, he doesn't say exactly how this manifests itself during operation.
He then contacted a PC service company in the hope that they could get his notebook back in working order. However, the technician who looked at the device said succinctly that there was nothing more that could be done and that the notebook would basically die after a yearunusablewere.
The manufacturer, in this case Asus, would have simplytoo many componentsstuffed into the housing that would give off too much heat. I will simply leave these statements uncommented at this point.
Fragile balance in notebook cooling
Modern notebooks with powerful hardwareget hot, unfortunately that is a fact. For example, you can see how high the temperatures get on a high-end device with an RTX 4090mread up.
This means that in a flat housing, as is common with notebooks, a power loss of200 watts and morecan be removed, sufficient air circulation is the top priority. If this is not guaranteed, the device can no longer develop its full performance or may even say goodbye with a blue screen.
Due to their design, there is not much space for large coolers in notebooks. Instead, there are 2 or in some cases 4 small heat sinks to which the heat pipes release the heat emitted by the CPU and GPU. Usually there are justthese little heatsinks and two fans, which stand between stable operation and an overheated notebook.
Possible causes
So everything really has to fit exactly so that the waste heat can be managed somehow. Already playing around with theFan characteristicscan quickly lead to instabilities under load. If you are aware of this, you can of course also influence the fan speeds manually; you don't have to worry about a defect in the CPU or graphics.
If the temperatures are too high, the components simply reduce the voltage or the clock speedIn extreme cases, simply switch off completely. Apart from the fan characteristics, there are also other reasons for excessive temperatures and the associated instabilities.
Staub:The most common reason is simply dirty fans and heat sinks clogged with dust. However, you can solve this problem yourself quickly and easily. To do this, simply blow the heat sink fins and fans carefully clean with a little compressed air.
Overclocking:If the notebook's BIOS allows it, overclocking could also cause thermal problems. If the CPU and GPU are operated outside of the specified specifications, this can significantly increase the power dissipation and simply overwhelm the cooling system.
The right surface:The base plates of powerful notebooks often have large ventilation grilles, and they are there for a reason. It is therefore important that the computer stands on a solid surface such as a table top. Soft surfaces such as a blanket or pillow can block the openings, and higher temperatures are the logical consequence.
Thermal paste:There have been cases where manufacturers have used too much or too little thermal paste. Both can have a negative impact on temperatures. In this case it makes sense to replace the paste. However, keep in mind that dismantling the cooler can lead to a loss of warranty. Especially for particularly powerful and high-priced notebooks, manufacturers are now increasingly using liquid metal, where it is unlikely that the wrong dosage will be chosen.
Ambient temperatures:It's actually logical, but for the sake of completeness I would like to mention that the operating temperatures of a notebook are naturally higher in a warm environment. Precisely because the cooling of notebooks is often already running at its limit, higher ambient temperatures have a faster and more drastic effect than is the case with a well-ventilated desktop PC.
Defect:Although it only happens very rarely, a defect in the cooling system could also be responsible for unusually high temperatures. It would be conceivable, for example, that the fan is damaged, has perhaps failed completely or no longer achieves its full performance. The only solution here is to replace the damaged component.
As you can see, there are a few possibilities why a notebook gets too hot and then runs unstable. Please let me know in the comments whether you have already had thermal problems with your notebook and how you solved them. And I would be particularly interested to know whether you have had similar experiences with PC service services as reddit user jjason82.
