When you look at some of the so called cool artists in the 80's, eg some heavy metal groups, they look quite ridiculous. Judas Priest or Iron Maiden for example look like farts. But also Adam And The Ants, Gary Numan and many others, who posed with cool attributes.
So if I have to answer the question with my "modern" eyes, I would say that almost none were cool. Swedish synthpoppers
Twice A Man were though. Their website:

then thought were cool, I have to say
Kraftwerk...
