PC case fan screws are small, often-overlooked fasteners that significantly impact system acoustics. They are subjected to continuous high-frequency motor vibration from the fan’s operation and are prone to backing out, leading to annoying chassis rattle and increased system noise. However, fans require frequent removal for dusting, cleaning, or upgrading,meaning the screws must be easily removable.
Don’t let vibration ruin your silence; secure the fan while keeping it easily accessible.
INCURE Re-Lok™ B22 Purple Light Duty Threadlocking Adhesive
For small-diameter screws (M3.5 or similar) that are critical for noise mitigation and stability but demand frequent serviceability, low strength is the necessary choice. The INCURE Re-Lok™ B22 Purple provides sufficient anti-vibration security, ensuring the fan remains tight and silent, yet is easily overcome by a standard screwdriver.
| Feature & Benefit | Technical Insight for PC Fan Screws | Conversion Value |
| Low Strength (Light Duty) | Provides enough thread lock to prevent vibration-induced loosening for fasteners up to M6, allowing for easy removal with basic hand tools. | Serviceable Silence: Secure the fan against rattle without permanently fusing screws into the case or radiator threads. |
| Small Fastener Focus | Ideal for the low torque requirements and small size of typical PC fan mounting screws. | Designed for Detail: Secures small fasteners without risking thread damage upon removal. |
| Vibration Security | Cures inside the thread gap, blocking high-frequency fan motor vibration from causing the screw to back out. | Eliminate Rattle: Stops the primary source of annoying mechanical noise caused by loose fans. |
| Thixotropic Viscosity | Exhibits excellent flow control, ensuring the product stays on the small threads without running onto the fan motor or case finish. | Clean Application: Use the product precisely where needed, avoiding cosmetic or functional contamination. |
Application Steps: Securing PC Case Fan Screws for Silent Operation
Preparation (Essential): Clean the threads of the screws and the fan frame/case holes as best as possible. A quick wipe to remove dust or oil residue is recommended. Ensure the parts are dry.
Application: Apply a single, pinpoint drop of Re-Lok™ B22 Purple to the middle threads of the fan screw. Only a minute amount is required due to the fastener size.
Assembly: Install the fan and thread the screws. Tighten the screws carefully until they are snug. Over-torquing is unnecessary and can damage the fan or the case.
Curing Time (Practical): While the initial cure is fast (around 20 minutes), allow a few hours for the adhesive to fully set before subjecting the system to continuous operation and vibration.
Stop risking noise and component wear; secure your cooling fans with chemical certainty.
