MECCANIXITY Heatsink Copper Pad Shim Alternatives: 6 Similar Picks Compared

Latest update:

As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.

You might need meccanixity heatsink copper pad shim alternatives if your cooling project demands different hardware dimensions or mounting methods. The original MECCANIXITY copper pad shims measure 20mm by 20mm by 1.5mm and come in a six-piece pack. These copper plates withstand temperatures up to 160 degrees Celsius. They work well for bridging flat 1.5mm physical gaps across notebook chips, memory modules, and graphic components that lack built-in thermal mounts.

However, you may require alternative dimensions, brands, or cooling features. A 1.5mm thickness or 20mm square layout does not fit every clearance gap. The 6 alternatives on this list were chosen because their specifications overlap with the original MECCANIXITY plates, sharing pure copper materials and chip-cooling designs. These options offer smaller 15mm by 15mm profiles, thinner 0.8mm shims, console-specific plates bundled with thermal paste, or active copper heatsink units with dedicated fans for server and desktop sockets.

Our top pick: MECCANIXITY 20mm x 20mm x 1.5mm Copper Shims.

Comparing the Alternatives to MECCANIXITY

Intel Socket 478 Copper Core CPU Cooler

The Intel Socket 478 Copper Core CPU Cooler replaces passive gap management with a dedicated active heatsink. Unlike the MECCANIXITY six-piece set of flat 20mm by 20mm by 1.5mm copper plates, this unit includes an integrated 2.5-inch fan and a solid copper core. It actively drives airflow across your processor rather than simply bridging clearance gaps to an existing cooler. However, you give up broad multi-device flexibility. The Intel cooler works only on Socket 478 motherboards, whereas MECCANIXITY shims fit diverse chipsets and memory modules. Choose this Intel cooler if you need a complete thermal replacement for a Socket 478 system instead of standalone spacing shims.

Dynatron Copper LGA1156 Blower Heatsink

The Dynatron K199 heatsink offers a complete active cooling assembly rather than flat thermal spacing material. While the MECCANIXITY set supplies six individual 20mm by 20mm by 1.5mm copper plates for manual gap filling, Dynatron delivers a 12.5-ounce copper heatsink equipped with a dedicated blower fan. Its 1.12-inch height fits restricted chassis clearances while directly cooling your processor. You trade away the flexible application of MECCANIXITY shims, which fit northbridges, memory modules, and varied chipsets. The Dynatron unit mounts specifically to Intel LGA 1156 sockets. Select this model if you need an active, all-in-one copper cooler for an LGA 1156 desktop build instead of individual shims.

Dynatron 1U Active Copper Heatsink

The Dynatron 1U Active Copper Heatsink provides full active cooling designed for LGA 1155 and LGA 1156 server setups. In contrast to MECCANIXITY shims, which are small 20mm by 20mm by 1.5mm passive copper squares, this unit measures 5 inches by 5 inches by 2.5 inches and weighs 15.2 ounces. It incorporates an active fan with dual ball bearings to push heat away directly. You sacrifice the compact versatility of MECCANIXITY shims, which fit graphics cards, memory modules, and small electronic chips. This cooler also cannot fit tight notebook spaces. You should pick this Dynatron cooler if you manage a 1U server chassis running compatible Intel sockets and require dedicated forced-air cooling.

NEW Games Order PS3 Copper Heatsink Shims

NEW Games Order PS3 Copper Heatsink Shims provide two 42mm copper plates measuring 1.2mm thick, bundled directly with Arctic Silver 5 thermal paste. This package spares you from sourcing separate thermal compound, which MECCANIXITY requires. The 1.2mm thickness also serves clearance gaps narrower than the 1.5mm MECCANIXITY profile. What you give up is piece count and small-component flexibility. MECCANIXITY provides six 20mm by 20mm plates suited for diverse ICs, graphics cards, and notebook memory chips. The 42mm size on this set is much larger and intended for console processors. Choose the NEW Games Order set if you are specifically repairing Sony PlayStation 3 processors and want included thermal paste.

Dynatron 1U Copper Blower Heatsink

The Dynatron R13 provides an active cooling solution featuring pure copper skiving and an integrated blower fan. While MECCANIXITY offers passive 20mm by 20mm by 1.5mm copper shims for gap filling, this Dynatron unit is an active thermal cooler designed for 95-watt processors within a 1.1-inch vertical height. It actively moves air across its copper fins to maintain server processor stability. However, you give up the versatile placement of MECCANIXITY shims, which fit notebooks, graphic cards, and discrete chipsets. The Dynatron cooler weighs 1.04 pounds and fits only Intel Socket 2011 Narrow ILM server boards. Choose this model if you need dedicated 1U active server cooling instead of passive copper spacer pads.

JIUWU 15x15x0.8mm Copper Heatsink Shims

JIUWU Copper Heatsink Shims provide a thinner profile and higher piece count than the MECCANIXITY package. This set delivers 20 copper plates sized at 15mm by 15mm with a 0.8mm thickness, weighing 0.32 ounces overall. The smaller 15mm width and thinner 0.8mm gauge make them easier to fit over compact laptop CPUs and GPUs where tighter spacing tolerances exist. You also receive 14 more shims than the six-piece MECCANIXITY set. In exchange, these shims cover less surface area than 20mm square pads and cannot fill gaps requiring 1.5mm thickness. Pick the JIUWU shims if you need slim 0.8mm copper pads in bulk for laptop maintenance.

Frequently asked questions

What is a thinner copper shim alternative to MECCANIXITY pads?

You can choose the JIUWU copper heatsink shims if you require a thinner profile. MECCANIXITY plates measure 1.5mm thick, whereas JIUWU shims measure 0.8mm thick. They feature a smaller 15mm by 15mm footprint designed for laptop CPU and GPU thermal gap filling. The pack includes 20 pure copper pieces.

Are there copper shim kits designed specifically for gaming consoles?

Yes, the NEW Games Order copper heatsink shims are tailored specifically for Sony PlayStation 3 processor repairs. This set provides two 1.2mm-thick polished copper plates measuring 42mm across. The package also includes Arctic Silver 5 thermal paste, giving you dedicated hardware to fill thermal gaps on console GPUs without cutting larger plates.

Can you replace thermal copper shims with an active CPU cooler?

You can switch from passive copper shims to an active CPU cooler if your socket and chassis permit. For example, the Intel Socket 478 Copper Core CPU Cooler provides an integrated 2.5-inch fan and copper core for Pentium 4 systems. This unit delivers active airflow directly to the processor instead of bridging gaps to an external heatsink.

Which copper cooler alternative fits a 1U server chassis?

The Dynatron 1U Copper Blower Heatsink model R13 fits 1U server heights. It features a compact 1.1-inch profile and pure copper skiving construction. Designed for 95-watt Intel Socket 2011 Narrow ILM configurations, it uses an integrated blower fan to manage heat in restricted rackmount environments rather than using passive shims.

What is an alternative copper cooler for Socket LGA 1156 motherboards?

The Dynatron Copper LGA1156 Blower Heatsink model K199 provides direct active cooling for Socket LGA 1156 desktop configurations. It features an integrated blower fan, copper construction, and dimensions of 3.21 inches by 3.35 inches by 1.12 inches. It weighs 12.5 ounces and mounts directly to the socket as a full thermal unit.

What options exist for legacy Socket LGA 1155 servers needing copper cooling?

The Dynatron 1U Active Copper Heatsink supports legacy LGA 1155 and LGA 1156 server sockets. It features dual ball bearings and measures 5 inches long, 5 inches wide, and 2.5 inches tall with a weight of 15.2 ounces. This provides an active copper thermal assembly instead of using flat copper shims.

How do shim dimensions affect thermal transfer when replacing MECCANIXITY pads?

Shim thickness and surface dimensions determine thermal interface contact between your chip and heatsink. MECCANIXITY shims measure 20mm by 20mm by 1.5mm, while alternatives like JIUWU measure 15mm by 15mm by 0.8mm. Matching the exact gap thickness ensures proper physical contact without bowing hardware or leaving unbridged spaces.
