I don't agree with 75* being way to hot. You can keep the fermentor at a nice 68* but once fermentation starts it is not uncommon for the fermentor to go up a few degrees because of the yeast activity. Yeast can stay alive past 100*
My Ipa's are always in the mid 70s during fermentation and...
The secondary fermentor is more of a "bright tank". Used primarily for dry hop additions and getting clarity out of the beer. There can be a little fermentation activity in the secondary, especially if you encountered a stuck fermentation in the primary.
Always start with a gravity reading just after you have pitched the yeast to the "fermenter" ( the original container used when you poured the wort into) and write this down in your notes.
Leave the brew in this container! Leave it alone! Rdwhahb..
