Moreover, the combo unit can be installed either horizontally or vertically, allowing enthusiasts to incorporate externally-modular upgrades for their chassis and build up superior water cooling system from an aesthetic standpoint.


Thermaltake recommends the following steps to be taken after completing your water loop setup

  1. It is strongly recommended to use market proven pre-mix coolant, such as Thermaltake C1000. It offers great performance while preventing corrosion within the entire cooling system.
  2. Fill the reservoir with coolant and cycle the power on and off several times while the pump pushing the coolant into the loop.
  3. DO NOT let the pump run dry, when there is no liquid entering the pump turn off your power immediately
  4. Fill the reservoir to the top as it will prevent air from going into the pump
  5. If necessary tilt the system slightly from side to side to bleed the air out of the loop.
  6. Place some paper towels under fittings and joining points to test for leaks.
  7. Run the loop with the fill port open for about 24 hours to completely bleed the air out of the loop
