Speed Fan

[Tenzer]

Hi. I would like to know why in my laptop one fan turns 10 times faster than the second. With increasing loads, only the speed of the first one changes. (Google translate)))on 1 screenshot work without other tasks. On the 2nd screenshot under load.

never mind ...

Sorry, but I have a laptop and two fans running on a common cooling system. in addition, they are the same size and brand that pushes me to the idea that they work to cool the CPU and GPU together to more effectively reduce temperature and noise.

The only thing I can see is that the fan on the left is closer to the CPU and Graphics chip.

So it is getting the brunt of the heat.

The gas in the tubs at the first (Left) fan is at a high temperature and the fan is at a fast rpm???

Then at the second (Right) fan the gas is at a reduced temperature and the fan is at a reduced speed???

@Tenzer is there a temperature difference coming out of the exhaust on the back???

Wouldn't it make more sense to make fans at roughly equal speeds for more efficient cooling? So I changed my fan because it is very buzzing and most likely it is because of too high rpm while the second is almost not spinning. Already after 2 months of operation after the replacement of a strong fan noise was repeated again, I do not think that the maintenance of fans included in the service of the laptop, at least so often. It is one thing to replace thermal paste, another thing fans. Yes, my other cheaper laptop is 1 fan which has not been serviced for about 5 years and there is no extraneous noise. Needless to doubt the quality of product for the price? Can I manually change the fan speeds to balance them?

P.S. What is bad is that calatraba will warm up towards the end where there will be a second cooling fan? The service life of both the fans think will increase and noise will be reduced.
