- tomswartz07 8y agoThe new BIOS updates addressed the whine issues I had. Might have been worth checking out before just taking it back :) EDIT: To be clear, my issues were resolved after an update back in Dec 2017: http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=YFTT1 http://www.dell.com/support/home/us/en/19/Drivers/DriversDet... "Optimize CPU loading to Improve EE noise" is specifically one of the issues that BIOS update addresses.
- skrebbel 8y agoWow, I'm impressed that a BIOS update can fix a coil whine. Got any background info on how they did it? Or did they just disable some core hardware feature for it?
- tomswartz07 8y agoI have no idea on the implementation, but it seems that they resolved it with 'CPU loading' optimizations: http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=YFTT1 http://www.dell.com/support/home/us/en/19/Drivers/DriversDet...

- meritt 8y agoOh, that is great news. I have an XPS 13 (9350) and the whine is incredibly frustrating.
- newhouseb 8y agoMake sure to install the Dell power management tools. Could be Placebo but I've noticed the whine significantly less with them installed.
- kuon 8y agoSurprisingly, I found coil whine much harder for the ears than fans. I installed an APC UPS under my desk, and there is a slight coil whine that it driving me nuts, while my GPU fans going crazy when I play never bothered me.
- geerlingguy 8y agoThis is one thing I've seen mentioned a lot, but never really noticed. Though my office (where I mostly use the laptop) is near an HVAC system, which usually provides a few dB of background noise to drown out subtler sounds.
