New RBP 17 short scratching noise when the fans starts

Hey there,

I just got my new RBP 17 2070 today. So far I configured Windows, updated bios to 1.04, updated Drivers and ran Firestrike (17047). No dead pixles and only minor coil whine. But i noticed a short scratching noise as soon as the fans start to rotate from 0 rpm (really bugging). Reproducable every time. Sounds like an very old HDD. I unscrewed the back plate and checked if the fans are some kind of stuck or scratching against the housing. But all 4 fans can be spinned freely and without any friction or sound by hand. And at full fan speed there are no weird sounds from the fans either, running totally normal. I dont know if this sound is the fans itself or any kind of electrical noise. Very strange. Never had anything similar on my older Laptops from different brands.

Anyone knows this? Suggestions? Send it back?

Thanks for any Input!

 

Hi, i have the same model as you and can you tell me if the problem is like the one from the video:

 

Yes! Sounds pretty similar, the noise at 0:04?! My sound is every time different. Sometimes longer, sometimes as short as yours. In real life it is pretty noticeable and bugging. I cant image that this is normal? This is 100% reproducible when the fans start.

Anyone knows what it is and what to do about it? I am considering a refund. Whats your opinion on that?

 

i just got an answer from the support and they said that there is nothing wrong with it, but personally it does bother me.

 

Yeah it bothers me too, here is my footage of it:
The background noise is not the fans. They are off until I click the mouse button. After that you can hear the buzz. Made it three times:

 

https://www.reddit.com/r/razer/comments/d6dl4r/hi_is_it_a_normal_thing_that_everytime_fans_start/ i posted it on reddit and they said that it's a normal thing for pwm fans so i think there is nothing we can do about it.

 

What did you end up doing?
