Key takeaways
- Route as many cables as possible behind the motherboard tray, through the rubber grommets.
- Use reusable Velcro ties instead of zip ties so you can adjust cabling during future upgrades.
- Flatten visible PSU cables with a comb kit for clean, parallel runs behind glass panels.
- Keep every wire clear of fan blades and the CPU cooler to protect airflow and components.
What's inside
Good cable management is more than vanity. Tidy wiring improves airflow so components run cooler, makes future upgrades far easier, and turns a rat’s nest into a build you are proud to show off through a glass side panel. The best part is that it costs almost nothing, a handful of Velcro ties and a cable comb kit are all most builds need.
This guide covers cable management from the ground up: planning your routing, using the case’s built-in channels, taming the bulky 24-pin and PCIe cables, and finishing the look behind the motherboard tray. Whether you are building fresh or cleaning up an existing rig, these steps deliver a cooler, cleaner PC.

Plan Your Routing Before You Tie Anything Down
Before securing a single cable, dry-fit everything and decide where each wire will run. The goal is to route cables behind the motherboard tray whenever possible, feeding them through the case’s rubber grommets to reach components from behind. Group cables by destination, the 24-pin, the CPU/EPS cable up top, PCIe power to the GPU, and SATA/fan cables, so you can bundle them logically rather than fighting a tangle later.
Use the Case’s Built-In Channels and Grommets
Modern cases are designed for cable management, with rubber-grommeted pass-throughs, routing channels, and tie-down points behind the tray. Feed each cable through the nearest grommet so only the connector shows on the component side. Route the bulky 24-pin motherboard cable through the grommet closest to its socket, and run the EPS/CPU power cable up the back to the top grommet, this keeps the visible side clean.
Bundle and Secure With Velcro and Combs
On the visible side, straighten your PSU cables with a comb kit like a Sirlyr PSU cable comb set so the 24-pin and PCIe leads run in neat parallel rows. Behind the tray, bundle cables with reusable Velcro ties from a cable management kit rather than zip ties, Velcro lets you adjust later without cutting. A kit with cable sleeves, clips, and ties covers everything a typical build needs.
Tame the Bulky Cables and Fan Wiring
The 24-pin and GPU PCIe cables are the thickest and hardest to hide. Route them behind the tray as much as possible and use a comb to flatten the exposed sections. For fans, run wires along frame edges and consider a fan hub to consolidate multiple headers into one tidy connection. Adhesive cable clips help pin stray fan and RGB wires against the frame so nothing floats loose in the airflow.
Finish the Back and Verify Airflow
The back of the motherboard tray is where the real bundling happens, and it does not have to be pretty, just flat enough to let the side panel close. Cinch everything with Velcro ties and adhesive anchor points, then double-check that no cable blocks a fan blade or drapes across the CPU cooler. Clean routing on the front and a compact bundle in the back mean better airflow and lower temperatures.

Frequently Asked Questions
Does cable management actually improve cooling?
Yes. Loose cables obstruct airflow across components and fans. Routing them behind the tray clears the path for air to move over the CPU cooler and GPU, lowering temperatures.
Velcro ties or zip ties, which is better?
Velcro ties. They hold just as well but are reusable, so you can add or swap components later without snipping and redoing everything. Zip ties are fine only for permanent bundles.
What do I need to start cable managing?
Very little: a cable management kit with Velcro ties, some adhesive clips, and a PSU cable comb set. Most builds cost under $20 to tidy completely.
How do I hide the bulky 24-pin cable?
Route it through the grommet closest to its socket so most of the length runs behind the tray, and use a comb to flatten the short visible section for a clean look.
Conclusion
Cable management rewards a little patience with a cooler, cleaner, upgrade-friendly PC. Plan your routing, use the case’s grommets and channels, bundle with reusable Velcro ties, and flatten the bulky cables with a comb. The result looks professional and actually helps your components breathe.
