Hi Plunder,
To really cool your stick down you could try the commandline-Tools "RemoveDrive V2.2" and "RestartSrDev" from this site:
http://www.uwe-sieber.de/drivetools_e.html
You can safely remove a device by Driveletter or you can use it's "friendly name" (wildcards supported)
This will remove all Sticks with "Sandisk" in their name:
removedrive *Sandisk* -L
With "RestartSrDev.exe" you can restart the stick.
