HP Pavilion 15z-cw100 notebook: Fan noise still an intermittent but really frustrating problem

[NancyK13]

Since I purchased this laptop I have had the exact same very noisy fan problem that many other people have noted on a previous (now closed) post [Excessive fan noise on brand new HP Pavilion - 15-cs0064st, Posted on 12-20-2018 02:26 PM].

As far as I can tell, the conclusion was that the noise was due to a manufacturing issue, and a now retired HP employee had reportedly spoken to someone in the right department at HP,  but to my knowledge there has been no response--certainly no one has ever reached out to me despite having a registered device. In the previous post many things were tried and ruled out so no need to rehash all of that, but I would like to know if HP offered any solution--or if not if any alternative was found. Although the noise does sometimes stop, when it is noisy it bothers everyone around as others have noted. Please help! I don't really want to resort to wearing earplugs all the time.

@NancyK13 -- the speed (and noise-level) of the fan is controlled by the motherboard. When it senses that the temperature of the CPU and/or the motherboard and/or the disk-drive is "too-high", it speeds-up the fan, to try to achieve a lower temperature.  

A notebook computer probably has air-intake vents on the bottom, to pull room-temperature air inside the case, and the notebook has air-exhaust vents, to push out the heated air from inside the case.

So:

1. be sure that there is nothing blocking the air-exhaust vents,
2. be sure that there is nothing blocking the air-intake vents,
3. use the computer in a room with lower air-temperature.

What #2 implies is that a notebook should always sit on a hard surface, not anything made of cloth, such as a place-setting, your lap, or a soft table-cloth, or your obliging, attention-loving, dog.

The cooler that the insides are, the slower the fan, and the less noise from the fan.

It is quite rude of you to "shoot the messenger".  My response is my response.

Unless you give more information about your issue, I stand by my response.
