I like to keep it at room temperature for quite awhile after racking into carboys. I don't make a particular effort to not take much sediment with it, but you do want it to be mostly off the gross lees. Here is a point we will probably depart because we make so much its easy for me to be patient. I let it sit for a couple to a few months at ambient room temperature (65 to 68ish, a little higher in the summer), although most gets made fall/winter), then into tertiary (this time trying to get no sediment) then cellar (52-65 winter/summer) for a year or more. Obviously you don't want to wait that long with none ready to drink, but I do recommend at least a couple weeks in secondary at room temperature. I think it helps clean up and the agitation plus warmth more or less insures there wasn't a stall you weren't aware of.
