It's been a few years since I've water cooled anything. Since my systems rarely stay together for more than a few months, it just doesn't make sense to break out the triple and quad radiators, pumps, blocks, tubing and reservoirs. If you ask about AIO cooling, I'll tell you that Noctua does it just as good with half of the hassle. Sometimes it's nice to put forth the effort, get out the storage bins filled with cooling parts and set out on a mission though.


Then again, sometimes it's just not needed. Unfortunately, sometimes you start down a path and later realize you're going in the wrong direction. Today's editorial is about starting in the wrong direction, but later figuring out we were right where we wanted to be all along.


Since Computex, I've gathered a Z87X motherboard from each of the major manufacturers to write an editorial on new features I personally find interesting. GIGABYTE was kind enough to send over their latest flagship Z87X board for Intel's 4th generation Core processor, Haswell. The GA-Z87X-OC Force uses new digital VRMs from International Rectifier. The new digital design means the VRMs run cooler than traditional MOSFITs, but GIGABYTE took the design of the OC Force and G1.Sniper 5 to a new level, incorporating liquid cooling in the PWM cooler.


Let's take a look at the new OC Force and see the new International Rectifier digital PWMs that use a single chip to replace the traditional 4-piece MOSFIT/Driver design.
