StarTech SILV5-THERMAL-PASTE Silver-Based Thermal Compound 5-Syringe Pack

Overview

The StarTech SILV5-THERMAL-PASTE is a five-syringe pack of silver-based thermal compound designed for CPU, GPU, and chipset heat-sink installations where reliable, long-term thermal transfer matters more than a single-application fix. Each 1.5g syringe contains a 60% metal oxide formulation rated at 3.195 W/m-K thermal conductivity — enough to handle processors up to 65W TDP and survive continuous operation from -30°C to 180°C without separating or drying out. If you're stocking a lab, servicing a fleet of workstations, or maintaining surveillance NVR appliances and edge compute nodes, buying five pre-measured syringes keeps your bench ready without over-ordering bulk compound that dries before you use it.

Key Features

• 3.195 W/m-K Thermal Conductivity: This rating places the compound solidly in the mid-performance bracket — more than adequate for processors at or below 65W TDP. You won't hit a thermal ceiling on mainstream desktop and server CPUs, embedded boards, or the compact SoC modules common in network video recorders and edge analytics appliances.
• 60% Metal Oxide Content: Higher metal oxide loading improves heat transfer versus standard white silicone compounds. The tradeoff is that this compound is mildly conductive — apply it carefully, keep it away from capacitors and board traces, and don't over-apply.
• 1.5g Per Syringe — 20 to 30 Total Applications: At roughly four to six applications per syringe (depending on die size), you get enough compound to service an entire rack of edge nodes or a full classroom lab refresh without hunting for a second order mid-project.
• -30°C to 180°C Operating Range: The compound stays stable well below freezing and well above the maximum junction temperature of virtually any commercial processor, so it won't crack during cold-warehouse startups or degrade in hot server closets without air conditioning.
• 65W CPU TDP Rating: Correctly sized for mainstream workstation, NVR, and embedded compute hardware. If you're working with high-core-count server CPUs or overclocked platforms pushing well beyond 65W, evaluate a higher-conductivity compound for those specific applications.
• Pre-Filled Syringe Format: Precision dispensing means no spills, no wasted compound, and consistent application weight across technicians. Each syringe can be capped and stored between uses — important if your service cadence is spread across weeks.
• CE and RoHS Certified: RoHS compliance confirms the formulation avoids restricted hazardous substances, which matters for enterprise and government procurement workflows that require documentation of materials compliance.
• 2-Year Manufacturer Warranty: StarTech backs the SILV5-THERMAL-PASTE with a 2-year warranty — useful assurance for a consumable that sits in your service kit for months between uses.

Integration and Compatibility

The SILV5-THERMAL-PASTE (often searched as SILV5 THERMAL PASTE) is compatible with any heat-sink-to-die interface where a silver-based mid-conductivity compound is appropriate: desktop and workstation CPUs, laptop repasting, embedded ARM and x86 SoC modules, GPU cooler replacements, and chipset heat sinks on NVR motherboards. It is not electrically insulating — do not use it as a gap filler or pad replacement between board components. Apply only to the die-to-heat-sink interface. The syringes are compatible with standard applicator tips and can be paired with isopropyl alcohol wipes for surface prep before application.

Frequently Asked Questions

Q: How many CPU applications does the SILV5-THERMAL-PASTE pack provide?

A: The five-syringe pack is rated for 20 to 30 total applications depending on die size. Each 1.5g syringe yields approximately four to six applications on a standard desktop or embedded processor die.

Q: What thermal conductivity does the SILV5-THERMAL-PASTE deliver?

A: The compound is rated at 3.195 W/m-K, with a 60% metal oxide content. This is appropriate for CPUs and embedded SoCs up to 65W TDP.

Q: Is the SILV5-THERMAL-PASTE electrically conductive?

A: Yes — the silver and metal oxide content makes this compound mildly electrically conductive. Keep it strictly on the die-to-heat-sink interface and away from PCB traces, capacitors, and exposed board contacts.

Q: What is the operating temperature range of the SILV5-THERMAL-PASTE?

A: The compound is rated for continuous use from -30°C to 180°C, covering cold-start environments such as unheated warehouse equipment rooms and sustained high-temperature server closets.

Q: Is the SILV5-THERMAL-PASTE RoHS compliant?

A: Yes. The SILV5-THERMAL-PASTE carries both CE and RoHS certifications, confirming it meets EU restricted hazardous substances requirements.

Q: What warranty does the SILV5-THERMAL-PASTE carry?

A: StarTech provides a 2-year manufacturer warranty on the SILV5-THERMAL-PASTE.

The SILV5-THERMAL-PASTE lands where most enterprise service scenarios actually live: mid-conductivity compound at 3.195 W/m-K, enough metal oxide loading to handle real heat transfer work, packaged in five precision syringes so you're not rationing paste from a bulk tub or tossing dried-out leftovers after a one-off job. I keep a pack like this on every service cart that touches NVR appliances, edge compute nodes, and workstation refreshes.

Technical Highlights:

• 3.195 W/m-K Conductivity: Handles the 65W TDP processors found in most commercial NVR platforms and embedded edge nodes without thermal throttling risk — you're not overpaying for exotic compound where you don't need it.
• -30°C to 180°C Stability: The compound won't crack in a cold-warehouse equipment room at startup (-30°C) or degrade in a server closet running hot (well within the 180°C ceiling), so you're not revisiting thermal failures six months after a service call.
• 20–30 Applications Across 5 Syringes: Pre-measured 1.5g syringes mean consistent application weight regardless of which technician is on the job — removes one variable from inconsistent thermal results across a multi-tech service team.

Deployment Considerations:

• The 60% metal oxide content makes this compound mildly conductive — brief your team to apply only at the die-to-heat-sink interface and always clean excess before power-on. This is a non-negotiable step, not a suggestion.
• Rated for processors up to 65W TDP. If your fleet includes high-core-count server CPUs or workstations running sustained loads well above that threshold, a higher-conductivity compound is the correct call for those specific units.

This pack is a practical fit for IT teams maintaining fleets of commercial surveillance appliances, embedded edge servers, or standard workstations — anywhere you need consistent, documented, RoHS-compliant thermal service compound ready on the bench without committing to a bulk container.
