First, change your TEMP environment variables to your HDD. This will cause all future temp files to go to the HDD.
Control Panel\All Control Panel Items\System > Advanced System Settings > Advanced > Environment Variables...
Edit your TEMP and TMP variable values to something like D:\Temp (or whatever your HDD is called).
Restart your PC.
You can now delete your old temp files in your appdata. You may also want to move your pagefile to your HDD, but keeping it on your SSD may result in better performance.
