Alphacool Panama HF38 PCIe Bracket

The Alphacool Panama HF38 is a PCIe slot cover that routes four water-cooling lines between internal components and external radiators or reservoirs. It installs in a standard expansion slot using a three-part tool-free assembly that seals with two O-rings. Black POM and zinc-coated steel construction keeps the bracket rigid while preserving full flow through an 18 mm inner diameter.

Builders adding external loops without drilling

This bracket suits custom-loop builders who want to run tubing outside the chassis while keeping neighbouring slots free. It accepts G 3/8" fittings directly and includes low-profile adapters for G 1/4" connections. Systems that cannot spare a rear expansion slot or that require more than four pass-through ports will need a different mounting solution.

18 mm unrestricted inner diameter

The Panama HF38 maintains an 18 mm clear bore through all four G 3/8" inner threads, avoiding the restriction common in thinner slot covers. Included adapters convert each port to G 1/4" inner thread without reducing that diameter. This single specification determines whether the bracket can deliver the flow rate your pump and blocks require.

Questions about this item

How many PCIe slots does the Alphacool 29886 bracket occupy inside the case?

It uses a single expansion slot; the three-piece design does not obstruct neighbouring slots so adjacent cards remain accessible.

What is the correct order for assembling the three parts during installation?

Mount the outer bracket to the chassis first, then join the inner section and tighten the two O-ring seals to complete the tool-free seal.

How often should the two O-ring seals be inspected or replaced to maintain a leak-free connection?

Check the O-rings whenever the loop is drained or reassembled; replace them if they show flattening, cracking or loss of elasticity.
