Size: 120mm vs 140mm for SA cases

Installation Tips That Actually Improve Cooling ⚡

Buying the fan is step one… installation is where you get the real result.

Match fan direction to your airflow plan

  • Front and bottom: intake
  • Back and top: exhaust If you reverse intake/exhaust, you can trap hot air and make temps worse.

Don’t starve the CPU cooler

If your CPU cooler is air-based, make sure there’s clear space for airflow. Also, avoid blocking the fan with cables. In many builds, cable clutter steals more airflow than people think.

TIP

Productivity Pro Tip ⚡

On Windows, use the PowerToys FancyZones utility to create custom snap layouts for your windows. It's a lifesaver for managing multiple apps on an ultrawide monitor, letting you organise your timeline, preview window, and asset folders perfectly for video editing.

Use a simple test loop after installation

After swapping fans, run a quick gaming session or a short stress test. Then check:

  • Are case temps calmer after 10–15 minutes?
  • Is noise reduced at the same fan speed?
  • Does your GPU still boost normally?

This is the easiest way to confirm you didn’t accidentally create a “mystery turbulence” setup. 😉
