Cluttering your PC from the inside not only makes it look better but also promotes more airflow as well. And if there is a jungle of cable hanging inside a case, it may lead to more heat buildup. And if you don’t have powerful PC case fans installed, there are high chances of hardware failure due to excess heat.

If you see GPU or CPU temperature rising up to 85 Degrees, it’s more or less due to poor management of your hardware cables. Bulky hardware cables can block the airflow inside a PC case, thus raising the temperature.

Also, if you have a gaming PC case with a transparent side panel, it’s better to tie up your hardware cables to add a decent look to your build. You can a lot of ATX PC cases with a good cable management system. Some PC cases come with separate channels at the side to hide your hardware cables.

Also, the cables that come with modular power supply are folded inside a sleeve, therefore, you don’t need any zip ties to fasten them together.

  • Some PC cases come with a side panel space for routing cables from the power supply and connecting right away with the hardware. Also, in you’ll find PC cases with routing holes at one side to pass the cables. Make sure the PC case you buy comes with routing holes that align with your power supply at the top of bottom of your case.
