A little cooler might give you more comfort but 205 is not bad. My 34normally runs 200 - 205. Heavy traffic will take it to 210/215. Hiway driving in the boonies might get me 190. Different story in my 57 though, rarely gets over 195, usually sits about 180, except in real heavy slow traffic, then it climbs to 210. 57 has stock radiator and stock engine turned fan, 34 has 10 inch pusher and 16 inch puller. You don't want to run too low or your combustion will be inefficient, especially with today's lousy gas.
