CRC PRACTICAL GUIDE

Step-by-Step Cleaning Guide

01

Shut down and unplug

Turn off the PC, switch the power supply off and unplug the power cable. Let the system cool before opening the case.

02

Open the case and inspect

Remove the side panel and check where dust has built up. Do not remove components unless a deeper clean is needed.

03

Blow away loose dust

Use your battery-powered air blower in short bursts and direct dust out of the case.

04

Hold fans still

Gently hold fan blades in place. Do not let fans spin freely from the airflow.

05

Clean filters and airflow areas

Remove dust filters and clean them separately. Clean vents, radiators and heatsinks, and let washed filters dry completely.

06

Clean components carefully

Use a clean lint-free cloth with a small amount of 98% isopropyl alcohol on suitable surfaces. Never spray liquid directly onto components.

07

Reassemble and check

Make sure everything is dry, reinstall filters and panels, and check cables and connections.

08

Power on and monitor

Check temperatures and fan behaviour after cleaning. Investigate sudden temperature increases.

Regular dusting

Use a battery-powered air blower to remove loose dust from fans, heatsinks, radiators, vents and filters. Short bursts work best.

Hold fan blades still

Do not let fans spin freely while cleaning. Hold the blades in place gently before using the air blower.

Clean dust filters

Remove and clean dust filters regularly. A quick clean every 2–4 weeks helps maintain good airflow.

Deeper cleaning

Every 6–12 months, remove larger dust build-up and carefully clean accessible heatsinks, radiators and surfaces. Reassemble and double-check connections.

98% isopropyl alcohol

For suitable component surfaces, use a small amount of 98% IPA on a clean, lint-free cloth. Never spray or pour liquid directly onto components, and allow everything to dry fully before powering on.

Good long-term habits

Keep the PC off the floor where possible, give it space to breathe, avoid direct sunlight and excessive humidity, and check temperatures or fan noise if performance changes.

Safety first: Turn off the PC, switch off the power supply and unplug the power cable before cleaning. Never open the PSU—even when unplugged, it can retain a dangerous electrical charge.
