[Q] Quiet Hissing/Electrical buzzing from tablet?

[Alek123]

Hey guys, does anyone else experience some quiet continuous popping and electrical sounds coming from inside the back of the tablet? If I put my ear on the back, it pretty much sounds like continuous popping and something like a laptop HDD running.

It's not that bad but gets noticeable in a quiet room especially on tegra apps, even dabbler.

I know it has a desktop GPU chip inside and I know this is common in desktop video cards but is this normal on this tablet?

The tablet had fan cooling system inside I believe.

Hissing mechanical noise during load...

I too have noticed this on my lte unit first night use.
I might be talking about something else, although regarding the hissing noise similar to harddrive (i dont really get the popping noise, nowhere near loud PoP sounds)
I can relate this noise very similar experience ive had on my computer with low level (in anotherwords cheap) onboard sound card -chip. Board was made by intel for dell. Basically it did the very close, in moments when hdd&ram cooperated in that computer under high cpu load, this sound came from the computers speakers.
Im surprised shield brings me back to the times 5 years earlier, i could hear it just now. Its random, but nothing i would be concerned of. Theres no point of rma this since its more of us noticing, i guess all the shield tablets produce this electric-static noise, speakers are pretty neat so maybe it was harder to hide imperfection of nvidias sound solution?
More accurate to confirm would be to know other tablets that use the same sound processor vs above mention hissing mechanical sound.
I can only hear it at night though, and frankly, it is loud but it still keeps me happy. My old oem pc was worse, it hissed even by moving the mouse around, it was so bad you could count dpi with closed eyes! Now that's what i call disturbing :laugh:

To me it sounds more like a voltage conversion-related sound like many power adapters make (including the Shield's) when under load. My power strip will also produce that sound if you plug high-power devices straight into its USB ports (I wish I knew the amperage on those ports).

EDIT: I have heard this sound on occasion myself is what I mean by this, and it doesn't sound like old "speaker squeaking" I've observed on older computers. I HAVE heard it on some laptops.

Thanks a lot for the feedback guys, i just wanted to know if there's something wrong with my tablet or it's something everyone gets. Anyway, i've also noticed some hissing when scrolling in Chrome. Not sure if it's the speakers or internal components hissing but it's not that big of a deal.
