The laptop overheats and makes noise despite cleaning and replacing the thermal paste, how to fix it?

Question

Iron

About a week ago, the laptop began to make noise and heat up. The first thing I looked at was aida 64, which showed that the temperature was about 70-90 degrees. Then I unsuccessfully vacuumed the cooler through the grille, the problem remained. A good friend advised me to disassemble the laptop, clean the cooler and replace the thermal paste. I disassembled the laptop, the cooler turned out to be clean, I replaced the thermal paste, assembled it and launched it. At first, for about half an hour, the laptop did not make any noise, the temperature was around 60 degrees and below, but after 30-40 minutes of work, the fan began to make noise and the temperature jumped sharply to 60-90 degrees. In general, everything that was before did not really help. A friend suggested that the problem might not be hardware, but software, so I tried to start the operating system from a flash drive, my flash drive is broken, so it didn’t work, however, I left the laptop with the error text for half an hour and the cooler behaved the same way, made noise, and the case heated up, that is, the problem is not software. Periodically, once an hour or half an hour, the cooler seems to start working, lowering the temperature down, before that the noise disappears abruptly and air starts to come out of the radiator grille, which is not usually observed, but after about 5-10 minutes of such cooling, the cooler turns into noise again, air stops escaping from the grate and the temperature begins to rise. And these 60-90 degrees without any load on the system, about 15-35 CPU usage. before that, the noise abruptly disappears and air begins to escape from the radiator grille, which is not usually observed, but after about 5-10 minutes of such cooling, the cooler turns into noise again, air stops escaping from the grille and the temperature begins to rise. And these 60-90 degrees without any load on the system, about 15-35 CPU usage. before that, the noise abruptly disappears and air begins to escape from the radiator grille, which is not usually observed, but after about 5-10 minutes of such cooling, the cooler turns into noise again, air stops escaping from the grille and the temperature begins to rise.

What could be causing this behaviour? How to fix it?

Answer 1

It was only necessary to replace the cooler. My old one was worn out and unfortunately was not collapsible. Worn with a special center for free diagnostics, my predictions were confirmed. They wanted to charge me about 2.5 kr for repairs, but I managed to do everything myself and ordered a new cooler via the Internet, screwed it on, all this cost me only 800 rubles. Just did a stress test, stable around 70 degrees all 20 plus minutes of the test.

Answer 2

What did you change the paste to? If on the soviet KPT-8, the effect is not surprising. Something like Arctic Silver 5 is suitable for laptops .

Answer 3

Well, if it makes noise and does not blow, it means that the air duct is blocked for blowing in or out, you need to see how the air enters and exits and what closes it.

Answer 4

Honestly, I didn’t understand where it’s buzzing and where it’s not blowing when it’s buzzing and blowing when it’s not buzzing.
Why don't you be like all normal people and take the laptop to the ss service with the words "something is heating up", and they will figure it out there.
I say this from the bell tower of the engineer of the service center for the repair of these same laptops. (True, since yesterday the former :) )
P.S. in all this sheet of unnecessary text, the main thing is not indicated - the laptop model.

Answer 5

Replace the entire cooling system of the laptop, or if you find it, replace the cooler, remove and blow through the radiator, well, in general, it’s better to go to a normal service

Answer 6

No one has ever answered the question. One service center engineer does not say what to do, the rest suggest changing the capacitors on the motherboard. This is some nonsense. Can someone help, the problem is most likely in the heat pipe. https://habrahabr.ru/sandbox/68790/
