    Surface Pro 4 makes frying popping sound only when held as portrait tablet with USB port down. Not related to fan; but related to hybrid cooling system. Only happens after processor warms up a little, does not happen right way after cold boot. Any one else have noise? Is this normal?

    Mine also has this frying sound after it has operated for a time. I have not used my Pro-4 as a tablet so I am experiencing this as I use it as a laptop. Thank you for any reassurance/thoughts. John

    I have the exact same issue. seems to only happen when the USB is on the bottom and in portrait mode. It sounds like there is air in the liquid cooling.

    did you replace your surface pro in the end? is this normal?

    Any further developments on the issue? I've got it too with brand new SP4 i7. It clicks while in very specific angle in portrait mode when and only when connectors face downwards. The sound looks like it is comming from the space between cameras and bottom right corner (portrait mode) where CPU roughly should be. Is it something that has detrimental effects with time or is it only a strange harmless sound?

    Just got my i5/256GB model last week and having this exact same problem. Sounds like rice bubbles cereal and only happens in portrait with USB port at the bottom. :(

    Will contact MS tomorrow.

    The solution: I've returned the device and the new one doesn't have the problem.
