The Toshiba Carrizo-Powered Laptop Is Screaming, Literally

Since writing a few days ago about buying an AMD Carrizo-powered laptop for Linux benchmarking, many Phoronix readers have been asking how it's going in testing out this Toshiba Satellite L55D-C5269 laptop. Well, very unpleasant so far.

I had bought this Toshiba laptop with AMD A10-8700P "Carrizo" APU as well as another similarly-priced Toshiba Satellite C55-C5241, that is basically the Intel equivalent of this laptop with Core i5-5200U "Broadwell" processor. It should be interesting to see how these 15.6-inch, 8GB RAM, 1TB HDD laptops perform. I'm still waiting for the Broadwell laptop to arrive, but so far I'm less than happy with this Toshiba Carrizo laptop...

This Toshiba L55D-C5269 is either broken or it's the loudest laptop I've heard in many years. It's obnoxiously loud and sounds like the heatsink fan has a broken fan blade or something stuck in there for this brand new laptop. Here's a brief listen:

I haven't touched a Toshiba laptop in many years... is this normal for them? Of the dozens of other laptops I've tested in the past years, I've never come across a defective heatsink fan like that, if this is indeed the case, for this brand new laptop fresh from the box. It sounded as loud as a broken CD in the tray, but wasn't the CD/DVD drive at all, and in fact coming from the exhaust ports on the laptop.

When moving the laptop to certain angles, the noise goes away. The noise also isn't constant but comes and goes frequently.

It might be overheating as the Windows 10 setup has taken over an hour before giving up... Unfortunately the Toshiba UEFI/BIOS doesn't expose any temperature data so not sure if it's overheating and throttling like hell or what's going on.

While I await to hear from Toshiba, do any Phoronix readers have any similar experiences?
