T430 makes unusual sound after premature termination of installation process.

Hi All

As explained in the title, I just received shipment of my "new" T430. Attempting to install OpenBSD, I forgot that I prefer to have ethernet plugged in when I do this (this is the installation procedure I 'know', so I risked terminating the installation procedure to move the computer to where I could plug it in. It warns that you should not do this "might leave your computer in an inconsistent state", but doesn't give any indication, from what I can tell, as to how one is supposed to terminate this process once started.

On re-start, with ethernet connected, it now makes a noise, as of a hard-drive or fan wiring away. It did not do this before, as far as I can tell. It was very quiet.

Is this normal? Is it indicative of the computer gradually heating up with use, or did I break something by exiting the installation procedure? The computer is still under warranty, I can bring it back to have it looked at, but it's a fair distance away.
