Grey thermal putty in a 50 g syringe tube

UPSIREN

UPSIREN U6 PRO Thermal Putty 50 g

SKU CH-Y6QZ-66B2V

High-performance thermal putty fills gaps completely, stays tacky without drying out, and suits automated dispensing or rework tasks

Weight 50 g

  • High thermal conductivity for efficient heat transfer
  • Fully cured formula prevents drying out over time
  • Low viscosity enables easy dispensing and stencil printing
  • RoHS compliant and halogen-free for restricted-substance applications
  • Replaces thermal pads by fully filling gaps with high compression

Product Identity

UPSIREN U6 PRO is a 50 g thermal putty designed to replace conventional thermal pads on graphics processors and other ICs. It arrives fully cured and will not dry out, bleed oil or lose performance over time. The material is RoHS compliant and halogen-free for regulated environments.

Target Users

This putty suits technicians and repair shops that need a compliant, non-drying compound for GPU rework, memory modules, power supplies or automotive electronics. It is not formulated for CPU heat-spreader applications, so builders seeking traditional silicone grease for a processor should look elsewhere. The compound also requires dispensing equipment or stencil printing for consistent results, which may not suit casual hobbyists.

Deciding Specification

The critical attribute is that the compound is explicitly not for CPU use and is intended as a thermal-pad replacement for GPUs and similar ICs. If your service task involves a graphics processor, memory module or power-supply component, the material matches the requirement; if the task is a standard CPU installation, it does not.

Questions about this item

How can I verify the UPSIREN U6 PRO putty is performing correctly after applying it to my GPU?

Monitor GPU core and memory temperatures under load; the putty should keep them lower than a standard pad because it fully fills gaps and maintains compression without drying out.

What comes in the package and what extra items are needed for installation?

The package contains 50 g of U6 PRO thermal putty; you will need a spatula or dispensing tool to apply it and isopropyl alcohol with a lint-free cloth to clean the old interface material first.

Which version or capacity should I choose for a graphics card rework?

The 50 g syringe is the only capacity offered and provides enough material for multiple GPU or memory-module applications.
