It is safe to keep the glue residues on the motherboard that had a backplate

This might seem a stupid question but i just want to be sure.

Some cooler have a backplate with sticky (really sticky!) edge on back of them in order to stick it on the motherboard. I removed mine with a lots of force but at least i removed it.

However, there are some left glue residues on the motherboard.. that would be pain to remove ! personnally i don't really care if they are keep there but it is safe ?

Adhesives generally used for this are non-conductive and non-corrosive, so leaving it on is fine.

If having the glue connect the motherboard to a big conductive plate wasn't a problem, the glue by itself won't be a problem either.
