Cable combs are one of those small parts that make a build look sharp right up until something else needs to clip on over the top of them. AsiaHorse's Aurora ARGB cover kit is exactly that "something else" - a shell that has to close cleanly around a cable run, and a comb sitting proud of that run is often the reason a cover won't sit flush no matter how carefully it's positioned.
Quick Answer
Cable combs should generally come off before an Aurora shell clips over that section of the run. The comb raises the cable's profile at that point, and the shell needs to close around a flat cable rather than a cable plus a fitting. Leaving a comb in place under the covered section is the single most likely reason a shell refuses to sit properly.
🪚 Why a comb causes trouble under a shell
A cable comb spaces individual wires apart and holds them at a slightly raised, more rigid profile than the cable would naturally sit at - which is exactly what makes it look sharp in an exposed run. That same raised profile is a problem for a moulded cover, because the shell is built to close around the cable's normal shape, not around a cable that's been widened and stiffened by a fitting. Forcing a shell over a combed section can leave it sitting unevenly, or put strain on the clip points that isn't obvious until the panel's back on.
Which combs actually need removing
Only the ones sitting under the section a shell will cover. A comb further along the run, beyond where the cover ends, is untouched by any of this and can stay exactly where it is. Since combs are far more common on sleeved extension kits than on factory stock cables, this question mostly comes up on builds that have already been dressed with an aftermarket extension.
🔧 The install order that avoids the problem
Removing a comb before fitting the shell, then sliding it back on afterwards once the cover's position is settled, loses nothing - combs aren't a one-time fitting, and nothing about the process damages them. Straightening the individual strands by hand before clipping the shell on also helps; a flat, evenly spread run closes far more cleanly than one still holding whatever shape the comb left it in.
What a forced fit actually risks
A shell that clips over a raised point can still appear to hold, at least at first glance, but an uneven closure puts uneven stress on the clip mechanism, and that's not something worth testing over time. It's a small enough step to remove a comb first that there's little reason to find out the hard way whether the shell will tolerate the extra height.
📦 Where removed combs should go
Keeping them with the sleeved extension's original packaging is the simplest approach, since they're worth having on hand if the shell is ever repositioned, removed, or if the cable route changes later in the build's life. Anyone tidying this kind of run more broadly might also find Evetech's cable management range useful for sorting combs, ties, and covers as a single job rather than several separate ones.
🔌 What stays constant regardless of prep
However the run underneath is prepared, the lighting side of the kit doesn't change - a single 5V 3-pin motherboard header still handles both power and sync for the pair of shells once they're clipped into place. Whatever colour is chosen, the same header requirement applies equally, so it's worth confirming a spare exists before the comb-removal step is even reached.
Evetech's case lighting range has a few other addressable products worth comparing before an order is finalised.
Frequently Asked Questions
Why would a cable comb cause fitting trouble?
It raises the cable's profile at that point, and the shell needs to close around the cable alone rather than around a cable plus a fitting.
Do all combs on the run need removing?
Only the ones sitting under the section a shell will actually cover - combs beyond that section are unaffected either way.
Can combs be refitted once the shell is on?
Yes - they slide back into place once the cover's position is settled, so nothing is lost by removing them for the fit.
What happens if a shell clips over a comb anyway?
It may appear to close, but an uneven fit puts uneven stress on the clip points, which is worth avoiding even when it seems to hold.
Do stock power supply cables usually have combs?
Rarely - this issue mainly comes up on builds already dressed with a sleeved extension kit that included combs.
Should the cable strands be flattened before fitting?
Yes - a flat, evenly spread run clips far more cleanly than one still holding the shape a comb left behind.
Where should removed combs be stored?
With the sleeved extension's packaging, so they're on hand if the shell is later repositioned or the run changes.
