Product Highlights & Details

High-Performance Thermal Conductivity

Our HY204 Thermal Putty delivers a strong thermal conductivity of 4.0 W/m·K—efficiently transferring heat away from electronic components and maintaining optimal thermal performance. This value aligns with industrial-grade thermal interface standards and ensures reliable heat management under rigorous conditions. Halnziye+1

Premium Quality & Versatile Packaging

This product arrives in a 100 g compact can, making it easy to store, handle, and apply. The pink hue not only makes it visually distinctive but also helps to pinpoint where it’s applied. Halnziye

Exceptional Gap-Filling Capability

Thermal putty is moldable and pliable, making it ideal for filling surface irregularities, bridging small gaps, and conforming precisely to component geometries—especially across complex power rails, capacitors, and inductors. This versatility sets it apart from conventional pads or paste. T-Global Technology

Multiple Color Options

Choosing HY204 gives you flexibility with color coding—available in pink, white, black, blue, or green, letting you coordinate with aesthetics or usage zones. Halnziye+1

Suggested Applications & Limitations

Optimized for Peripheral Components (NOT Direct Die)

This putty is specially engineered for use on power rails, inductors, capacitors, VRAM, and other secondary cooling areas across laptop and GPU PCBs. It is not intended for direct CPU or GPU die applications—preserve your motherboard’s integrity and ensure best performance by avoiding such misuse.

Great for Various Devices

Ideal for laptops, discrete GPUs, mining rigs, and other electronics where efficient thermal management is necessary around high-power components. Halnziye+1

Technical Specifications

These specs reflect a robust and reliable material that remains stable under thermal cycling and can handle typical operating environments without degradation. Halnziye

Why Choose HY204?

Greater Coverage, Fewer Gaps

Unlike rigid thermal pads, HY204’s malleable nature ensures seamless coverage—no air gaps or heat spots. It molds to microscopic heights and depths creating even contact with heat spreaders or metal covers.

Easy to Apply, Yet Durable

Its putty-like consistency allows for quick, precise application. Once placed, it sets and remains stable under heat fluctuations—a reliable choice for long-term usage.

Cost-Efficient & Quantitative

Available in a practical 100 g can, it’s great for multiple application jobs, saving on packaging waste and per-gram cost—especially useful for service technicians or bulk deployers.

Visually Trackable Application

The pink color adds a visible layer during installation, helping confirm full contact coverage without contaminating sensitive areas. This visual advantage also assists with easy cleanup or removal later.

Community Insights (Tech Enthusiasts & DIY Experts)
