I just purchased a Gertbot board. On inspection, I noticed quite a bit of excess thermal glue/paste on the heatsinks. Do I need to worry about shorts, or is the paste insulating? I also noticed that one of the heatsinks is only a hair away from one of the onboard caps solder joint. I'm wondering if it might be best to remove the heatsink and re-attach it in a better position. Not sure what to use to remove it and what to use as a paste/glue so I don't create more problems. I haven't tried the board yet to avoid shorts. Thanks!
