I had similar problems there. I have found the "push pull" method is best.
Hook your controls to molex connections for fans so they run full speed and check your temps then.
You will notice an increase during gaming regardless. 34c at idle is normal for me. E8400 @ 3.0 ghz but I will see the increase of about 10-15 deg while under load.
Also, which way do you have your airflow going over your radiator? Is it pullin into the case or venting out?
