PC water cooling filling aids are designed to make it easier to get fluid into an empty water cooling loop with as little spillage as possible. There are several types to choose from, depending on your preference. When you’re creating a custom PC water cooling system, filling the water loop for the first time can be one of the most frustrating parts. Fillports are helpful but small, and bleeding all of the air out of the components takes time and patience. Filling aids like threaded funnels and fill bottles make the job easier and cleaner. TITAN RIG offers filling aids in multiple forms from several brands to make filling your new custom water loop as easy and mess-free as possible.
