Humming noise

[raynold2010]

Hi all,

Bought my 2017 MBP 15 TB, 16GB, 256SSD three days ago. Yesterday, started to hear some sort of humming sound from the fan area. it's a constant, low frequency sound, not oscillating.

Not using any energy consuming software.

Could it be the PSU ? Bringing it today to the local Apple store, but maybe you could give an advice before.

Thanks.

Ok, my Apple store didn't find anything (big surprise), but had no other choice than exchange it. So far, so good.
