HY234 CN100 1kg Silicone Thermal Putty 4.0W/m·K for GPU VRM & ASIC Hash Boards

HY234-CN100 Silicone Thermal Putty 4.0W/mK | 1kg Pink Gap-Filling Compound for GPU VRM, ASIC Hash Boards & High-Power Electronics

HY234-CN100 is a pink silicone thermal putty with >4.0W/mK thermal conductivity, supplied in a 1kg bulk can for GPU VRM stacks, ASIC hashboard chip surfaces, and high-power electronics. Soft and compressible — fills uneven gaps between heat-generating components and heat sinks where a traditional thermal pad cannot conform and a paste is too thin to bridge the step.

Engineered for the conditions that destroy ordinary thermal compounds in mining and industrial duty: stable thermal performance from -50°C to +200°C continuous (instantaneous up to +340°C), low oil separation, strong resistance to aging, and no rapid pump-out under thermal cycling. Pink colour shows clearly when fully spread, eliminating guesswork during application.

Why a Putty Instead of a Paste or a Pad?

• Fills irregular gaps — VRM stacks, memory packages, and step transitions where thickness varies across the interface.
• No pump-out under repeated thermal cycling — paste alternatives migrate over time, putty stays in place.
• Conformable but stable — soft enough to fill the gap on assembly, stiff enough to hold position once in place.
• RoHS / CE / SVHC / MSDS certified — ready for industrial and commercial deployment.
• 1kg bulk packaging — economical for hashboard fleet rebuilds and OEM use.

FAQ — HY234-CN100 Thermal Putty

Q: Putty vs paste — which one for ASIC hashboards?
A: Use putty (HY234-CN100) where the gap is large or uneven — VRM stacks, memory blocks, multi-step surfaces. Use paste (HY883 or KL1040) where the chip die is flat and lapped against the heatsink with minimal gap. Many hashboard rebuilds use both: paste on the ASIC dies, putty on the surrounding components.

Q: Application thickness?
A: Apply slightly thicker than the gap so the putty compresses to fill it fully. After assembly, it should be visibly squeezed out around the edges — that confirms full contact. Excess can be trimmed.

Q: Does the pink colour fade over time?
A: The silicone matrix is stable up to 200°C continuous, well within ASIC operating temperatures. Colour stays consistent across the lifetime of normal hashboard duty.

Q: Bulk pricing for repair benches and mining farms?
