You could always put your Xbox in a sealed air tight container and stick it in the freezer
Hehe, on a serious note - Install the drive and play a few games off it. After a while, feel the top of the drive to see how hot it gets. If it gets really
hot with the cover off, it will get even hotter with the case on.
If it's not too bad to touch, try it for a while and if you start to experience games crashing and other lockups it's a fair bet that the drive is going into meltdown
Install the new Evox dash too, it'll display the temp of the drive.
If all else fails, piss it off and get a Western Digital
