Modifying the MCP350 For Incresed Flow
NEWBY ALERT:

Your mod is a GREAT idea, RoboTech. But, I have to warn any unsuspecting newbies not to expect a doubling in flow or in cooling performance. Please read RobotTech's article, and don't jump to conclusions!

Even in a good scenario (low resistance waterblock and low resistance radiator), you were getting around 46.17% increase in flow, not 100% increase in flow. The ability to get 100% increase in flow only happens in bench test scenarios where nothing is attached. Again, that is a HUGE win for performance, but not a doubling.

Then, for what really matters: temperature. This is too hard to predict, and most of us here are smart enough to avoid any glib statements of what YOU will get in a system. However, don't expect your CPU temps to drop 10C by making this mod. You might get 1C to 4C improvement depending upon your setup, and that's just pulling numbers out of thin air, because IT DEPENDS UPON YOUR SETUP.
