Rising smoke from my hard drive

Hello everyone,
I did something silly. I bought a kit that would let me plug my 1TB seagate drive into a relatives pc through USB because theirs is one of those tiny all in one units. As you can probably guess this came with a separate power supply to let me power up the drive. One of the pieces of this kit is a 4 pin molex to sata connector, as the cable that runs from the transformer ends in a female molex adapter (with 3 out of 4 pins active). Now this female molex connector is pretty ambiguous in shape and after using a few times and not taking care, I connected it upside down. The drive was working fine, and it wasn't until I saw the small plume of smoke rising from the end of the drive that I realised something was wrong. After leaving it for about an hour or so to let all the parts cool and allow anything melted to solidify fully I tried the drive again. It still functioned fine, with no diminished transfer rate and no corrupt data, but the circuit board that sits at the front on the bottom of the drive overheats even when properly connected. Now my question is, would this drive be safe to use back in my own pc? I have a custom build with front, rear and dual side 120mm case fans with pretty good airflow on the inside and I dust regularly, but would this be enough to keep the temperature down for safe operation? And if not, is there a way to replace the circuit board on the bottom of the drive? My master drive is only 500gb, so I have a lot of stuff stored on the one in question and i really dont want to lose it all!

Thanks for reading, any advice would be appreciated :)
 
Solution
Hard drive controllers can get very hot under normal use. I would guess that the smoke was from the cheap power connector. They may have used too small of wires to handle the current. Your drive is probably ok. It will cease to function long before it gets hot enough to start a fire.
