Playlist of other “Upgrade 2012″ videos: www.youtube.com In this episode I spend some more time talking about plans for this build and showing some water cooling maintenance. Once I’m done with flushing the radiators, I’m going to give them a good vinegar soak, then flush again and rinse with distilled water to ensure they’re good and clean. This build keep snowballing though. Stay tuned for my next update which will include some interesting stuff!
