StarTech SILVGREASE1 Metal Oxide Thermal Compound

Overview

The StarTech SILVGREASE1 is a 1.5g tube of metal oxide thermal paste built for CPU and heatsink installs where reliable heat transfer matters more than brand-name marketing. It's a small, single-purpose product — one tube, one job — but the numbers behind it matter to anyone specifying thermal interface material for a server build, workstation refresh, or field repair kit. Rated for CPUs up to 65W TDP, SILVGREASE1 is sized for spot repairs and small deployments rather than bulk data center re-pasting, where a larger syringe format would make more sense.

Key Features

• Thermal Conductivity >3.195 W/m-K at 25°C: higher conductivity moves heat off the die and into the heatsink faster, which matters most on CPUs running near their thermal ceiling — the difference between a chip throttling under sustained load and one holding clock speed.
• Thermal Resistance <0.067°C-in²/W at 25°C: low resistance means less temperature drop across the paste layer itself, so more of your heatsink's rated cooling capacity actually reaches the processor instead of being lost at the interface.
• Bleed <0.05% at 150°C/24 Hours: minimal oil separation at sustained high temperature keeps the compound from migrating onto the motherboard or socket area over long uptime cycles — relevant for always-on servers and industrial PCs that never power down.
• Evaporation <0.001% at 150°C/24 Hours: the paste stays put chemically instead of drying out, which is what causes thermal performance to degrade and re-pasting to become necessary in aging systems. This spec is why a single application should hold up for years, not months.
• Specific Gravity >2.4 at 25°C: a denser compound generally carries more thermally conductive filler material per unit volume, correlating with the conductivity rating above rather than being padded with lighter, less effective binder.
• Operating Temperature -30°C to 180°C: covers everything from an unheated equipment closet in winter to a CPU running flat-out in a sealed enclosure, so you're not choosing a different compound for indoor IT closets versus warmer industrial cabinets.
• 1.5g Paste Volume, Good for 4-6 Applications: sized for a repair tech doing several installs from one tube rather than a single one-and-done job — useful for a field kit or bench stock rather than a one-time build.
• Rated up to 65W CPU TDP: matches mainstream desktop and entry workstation CPUs; if you're pasting a high-TDP workstation or server processor above that figure, budget for a compound rated at the higher wattage instead.
• CE and RoHS Certified: confirms the compound meets EU electromagnetic and hazardous-substance compliance standards, relevant if your organization has procurement requirements tied to those certifications.
• 2-Year Warranty: a defined coverage window on the product itself, useful when this line item needs to clear a standard IT asset audit.

Integration & Compatibility

SILVGREASE1 is a generic-application thermal compound — it isn't chip-specific, so it works across desktop and workstation CPU installs, heatsink swaps, and cooler upgrades where the mating surfaces are a bare processor IHS and heatsink base. It's a natural companion item alongside server and computer hardware builds, and pairs well with a cooler or heatsink replacement job rather than being a standalone purchase. For IT teams standardizing a repair kit, keeping a tube of SILVGREASE1 on hand alongside spare mounting hardware from the broader StarTech catalog covers most CPU thermal service calls without special-ordering per repair.

Frequently Asked Questions

Q: What CPU wattage is the StarTech SILVGREASE1 rated for?

A: SILVGREASE1 is rated for CPUs up to 65W TDP, matching mainstream desktop and entry-level workstation processors.

Q: How many applications does one tube of SILVGREASE1 cover?

A: A single 1.5g tube is good for approximately 4-6 applications, depending on CPU size and application thickness.

Q: What is the warranty on the SILVGREASE1?

A: SILVGREASE1 carries a 2-year warranty.

Q: Is the SILVGREASE1 CE and RoHS certified?

A: Yes, SILVGREASE1 is CE and RoHS certified.

Q: What temperature range can SILVGREASE1 handle?

A: SILVGREASE1 has an operating temperature range of -30°C to 180°C.

Q: Does SILVGREASE1 dry out or bleed over time?

A: No — it's rated for less than 0.001% evaporation and less than 0.05% bleed at 150°C over 24 hours, so it holds its thermal performance over long uptime without needing frequent reapplication.

SILVGREASE1 crosses my bench whenever a repair ticket calls for a cooler swap on a 65W-class CPU. The number I actually check first is thermal resistance — StarTech rates this compound under 0.067°C-in²/W at 25°C, which tells you how little temperature drop you're losing at the paste layer itself rather than just trusting a marketing conductivity figure.

Technical Highlights:

• Thermal Conductivity >3.195 W/m-K: mid-tier metal oxide compound performance — enough headroom for a 65W desktop or entry workstation CPU without needing a silver or diamond-filled paste.
• Evaporation <0.001% at 150°C/24 Hours: this is the spec that predicts whether you'll be back inside this case in 18 months. A compound that doesn't dry out holds its rated performance for the life of the build.
• 1.5g Tube, 4-6 Applications: right-sized for a repair bench doing a handful of jobs, not a data center re-pasting sweep — budget a different SKU size if you're doing volume work.

Deployment Considerations:

• Rated only to 65W TDP — verify your CPU's actual TDP before specifying SILVGREASE1 on a higher-wattage workstation or server chip; a higher-rated compound is the correct call above that threshold.
• Standard even, thin-layer application technique still applies — the low bleed and evaporation numbers only hold up if the paste is applied correctly; over-application doesn't improve heat transfer and can squeeze out past the die.

This is the right tube to keep in a bench repair kit for standard desktop and workstation CPU swaps up to 65W — for high-TDP server processors, step up to a compound with a higher wattage rating instead.
