Er, you might want to clarify the hot gun glue bit - using a normal hot glue gun isn't going to help your cooling *at all*, as the plastic glue is quite a good insulator. You need special heat conducting glue, or heatsinks with this special glue already applied. Normal glue, sticky pads and the likes are only going to make it worse...
Also note that isn't really glue, it is a
thermal grease. Which means that the OP needs figure out a way to fasten that heatsink as well.
