pictures?

It is probably just the fan driver that you toasted, if so it's probably just that fan header and any others that share that driver. If it were me I'd try to very carefully cut away that smoked driver chip and then see if it powers up and runs. The reason I remove the burnt chip is from an abundance of caution as it's possible it's damage could end up shorting 12V to ground and that would damage other stuff.

Pretty much yes
