    Before you install it

    This is a component, not an assembly — how it goes in depends on the loop it is joining. What does not change is the last step: leak test before power. Run the pump on a bench supply with the rest of the system unpowered. 24 hours is the standard, an hour is the minimum.

    Custom water cooling is installed by you, at your own risk. We are not responsible for leaks, or for damage to your parts or system. If you're unsure at any step, ask before you power the loop.

    About this part

    The CT-D5-180-X-V2 is a pump reservoir combo designed for use in liquid cooling loops. The square armor design gives a distinctive look compared to most pump reservoir combos. The unit features a capacity of 350 milliliters and two intake ports—one port for the loop return, one for filling—along with a single port for outputting coolant. It is mountable on any 120mm fan location using an optional bracket (B-BKT-105).

    Minor issues

    It's a good product. However, when it arrived it came with a mounting bracket that was already attached and the bracket was bent. Not to big a deal since I didn't think it came with one (or wasn't listed with one) so I had already ordered one for it. I also had issues getting power to it. I tried a couple cables before it finally powered on. I needed to reorganize the cables so I disconnected and reconnected. Then it wouldn't power on again. Disconnected and reconnected a few times with different connectors on the same cable. Finally powered on again.

    Everything works fine now. Just makes me think this was a returned or RMA product and that was not what I ordered.

    Questions people ask about this part

    Answers specific to CT-D5-180-X-V2. If yours isn't here, ask — we'd rather talk you out of the wrong part than sell you one.

    What does this part fit?
    This part is specified by what it connects to, not by a card model:
    • Loop: Non-Aluminum
    • Fitting: G1/4in. Thread

      Check those against your build before you order. If anything does not match, ask us first — it is cheaper than a return. Part number CT-D5-180-X-V2.

      Is it in stock, and when will it ship?
      Yes — only 4 left in Boise, Idaho. Orders placed before 2:00 PM MST on a business day ship the same day — we do not ship weekends or US holidays. Overnight delivery is available at checkout.
      Can I return it if it turns out not to fit?
      Yes. Returns are accepted within 30 days and are easy to start in the support center. Unopened items can be returned for store credit with no restocking fee; other returns carry a restocking fee, higher for items that have been installed or used. So we would rather check the fit with you first: send us the model and we will check it against this part.
      Will I pay import duties or customs charges on delivery?
      Not on a US order. US import duties and tariffs are already included in the price, so nothing is collected at the door and there is no brokerage fee. Orders shipped outside the US may owe that country's customs fees and duties.
      Who handles the warranty?
      BYKSKI.US, the exclusive US distributor, from Boise, Idaho. Claims are handled domestically rather than returned to an overseas factory. Installation is at your own risk: we are not responsible for leaks or damage to other hardware.
      Is shipping free?
      Yes — shipping is included at this price for addresses in the lower 48 US states.
      Are printed instructions included?
      No printed manual is included. Installation references are in the product gallery images, and the install guides on this site cover the process step by step.
      Do I need anything else to use it?
      Check the parts list above against what you already have. If you are building a loop from scratch, send us the full parts list and we will tell you what is missing before you order.
