Silver Thermal Grease CPU Heatsink Compound Paste Syringe (5-pack)

Bottom line: The JacobsParts Silver Thermal Grease CPU Heatsink Compound Paste Syringe ($6.99 on Amazon as of 2026-10-21 16:25 UTC): Five 1.0g syringes per pack at 7.99 total, roughly 1.60 per tube; main trade-off: 1.0g per tube is thin for large IHS or dual-socket workstation boards.

Pros & Cons

Pros

  • ✓ Five 1.0g syringes per pack at 7.99 total, roughly 1.60 per tube
  • ✓ Rated above 3.17 W/m.k thermal conductivity from 20% metal oxide loading
  • ✓ Thermal resistance under 0.067 C-in2/w for tight die-to-heatsink transfer
  • ✓ -50 to 180 C operating range covers cold storage and sustained load

Cons

  • ✗ 1.0g per tube is thin for large IHS or dual-socket workstation boards
  • ✗ Silver-loaded and metal-oxide based, so stray paste near pins needs care
  • ✗ 3.17 W/m.k trails high-end pastes that publish 8-12 W/m.k figures
  • ✗ Syringe applicators lack a spreader tool, so mount pressure does the work

Manufacturer description

The JacobsParts silver thermal grease 5-pack covers a full retro build season without a second order. Each syringe holds 1.0g of polysynthetic silver compound rated at greater than 3.17 W/m.k thermal conductivity and under 0.067 degrees C-in2/w thermal resistance, so heat moves off the die and into the heatsink instead of pooling under a dried-out pad. The 20% metal oxide loading is what carries that conductivity, and the -50 to 180 degrees C operating range means it holds up whether you are reviving a Socket 7 box in a cold basement or running a modern chip under sustained load. Five tubes…

SpecPicks Verdict

SpecPicks scored JacobsParts Silver Thermal Grease CPU Heatsink Compound Paste Syringe using a rating × review-volume × price-fit model applied to published specs and reviews across the retro cpu coolers & fans category. JacobsParts's retro cpu coolers & fans lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for retro cpu coolers & fans of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

How many CPUs will one 1.0g tube cover?

One 1.0g syringe is sized for a single application on a typical desktop CPU using a rice-grain dot. With five tubes in the pack, plan on roughly one tube per machine for repasting jobs.

Is this thermal paste electrically conductive?

The listing specifies a polysynthetic silver compound with 20% metal oxide compounds rather than pure metal. Keep it off pins and surface-mount components anyway, and check the manufacturer listing for conductivity specifics before use near exposed contacts.

What temperature range can this compound handle?

JacobsParts rates it for -50 to 180 degrees C operation, which covers cold-room retro builds through sustained full-load CPU temperatures on both vintage and modern sockets.

How does 3.17 W/m.k compare to premium thermal pastes?

At greater than 3.17 W/m.k it sits in budget-compound territory; enthusiast pastes commonly publish 8 W/m.k and up. For retro CPUs with modest TDPs, the gap matters far less than having fresh paste instead of 20-year-old dried compound.

Is this worth buying over a single premium syringe?

At 7.99 for five tubes it works out to about 1.60 per application, which suits restorers working through multiple boards. If you are pasting one high-TDP chip you plan to overclock, a single higher-conductivity syringe is the better spend.
