Where should I go to farm parts for the Trading Post Auctioneer?

I have had the Trading Post for a while and I would like to complete Auctioning for Parts and make the Auctioneer, but I'm wondering if I'm going to the right place to farm for the items.
I would like to know where in each of the zones for Super Cooling Module, Cyclical Power Module and Universal Language Module are some good spots to farm for the items?
I have decent gear so I can make some big pulls, so I am looking for places where the mobs doesn't have much hp and either there are a lot of them or they have a fast respawn.
