The temperature shouldn't rise. The moisture content(as measured by the dew point) in a house with all open doors should be nearly the same. If you were somehow causing a negative pressure pulling outdoor air inside I could see this happening but other than that I can't make sense of this.
I tried this once but once the cooler downstairs air mixed with the warmer air upstairs, eventually the heat upstairs overwhelmed the downstairs temperature after a few days and the basement wasn't cool anymore and there was little cool air left to lose downstairs to cool the upstairs and the air conditioner was powered back on. ..put that together with dew points in the 70s outdoors and I needed to run the AC to bring the dew point down to a safe level in the basement to prevent mold. So for me, it worked for awhile and is plenty good when it isn't in the 80's outside and there is a good cold thermal mass in the basement. It gets exhausted quickly with solar exposure in my case.
