With only 2 fans in a 1030, try putting them both in the back blowing out. It's the "stock" configuration, and should give slightly better airflow/case temps. The small difference between idle and load temps pretty much indicates high ambient as the problem, though- try testing it early in the morning, when the house/apartment is coolest.
Unless that's not full load- running prime 95 or one of the distributed clients (Seti, Folding, RC5) will accomplish that.
