Don't open the loop unless you have a spare heat sink set (some guy is selling them on Ebay for $20 each, if your Monarch had a leak in the cooling system that's a nice fix). Those things run the chips quite warm (60c) and any disruption in cooling will blow the chips since it is *very* thin (which really helps with heat dissipation).

Use the V3X and FBX values to slow it down, remember the second digit is hexidecimal but voltages above 4 are locked out) and have fun with it.
