I guess no one should go into malls, hotels, motels, or office buildings
there during the summer, eh? Where did you get the idea that AC is rare in
Seattle? I didn't find that to be so during my 32+ years of residency in
the area.
Suggest you get a large fan, take off the case cover, or one side if
possible, during the few hot days and use that to cool it down. I keep the
house, here in Eastern Washington, at 73 and one fan exhausting an adjacent
window with one case panel off. I run 33-35C under load when it is 105F
outside.
Good luck

Unfortunately, air conditioning in the Seattle area is rare. It is just
not
cost effective for the handful of days that traditionally get this warm. I
have the windows open and the fans running. It will get down to the mid
50s
to low 60s during the evening, so this is only a problem during the mid to
late afternoon. During the rest of the year, temperatures are not a
problem.
P.S. I don't even set my thermostat to 70 in the winter. 68 is plenty warm
enough :)
