Just finished a 60-to-80mm fanadapter... something like this one http://www.overclockers.com/tips238/ but for a PAL6035. It's a Mark I so it's kind of ugly, but it works. Using an old, low-output 80mm psu fan (all I have available) it's knocked a couple degrees off CPU temps, but better still it's so quiet! Not having a high-rpm 60mm fan in the case makes a *world* of difference.
