Coracer’s GPE-01 Graphene Pad for AM5 Achieves 130 W/m·K Conductivity

Coracer, a lesser-known Chinese accessories manufacturer, recently introduced a version of its GPE-01 graphene thermal pad specifically designed for AMD’s AM5 processors. Until now, this pad has been compatible only with Intel’s LGA 1851 and LGA 1700 sockets. The new AM5 model measures 32×32 mm, allowing it to cover the entire IHS without hanging over the edges. Thermal paste has long been the go-to option for filling the microscopic gap between CPU and cooler, but in recent years, enthusiasts have explored alternatives like liquid metal and pre-cut thermal pads. Graphene-based products have gained traction because graphene conducts heat exceptionally well. Coracer claims its GPE-01 combines graphene with silicon to achieve a thermal conductivity of 130 W/mK, which is about twice that of popular liquid metal compounds. An insulating layer around the graphene prevents any risk of shorting out the processor’s circuits.

Coracer also asserts that the GPE-01 can maintain performance for up to ten years. Regular thermal paste tends to dry out and degrade over time, requiring reapplication every few years. A graphene pad like this could eliminate that chore until you swap out your CPU unless you keep the same system for over a decade. Interestingly, Coracer has almost no online footprint. Segotep, another Chinese brand, introduced a GPE-01 pad for Intel CPUs late last year, so it’s unclear whether Coracer is a spin-off or if Segotep licensed the design. As of now, there’s no word on pricing or availability for the AM5 version. The Intel-focused GPE-01 sells for around $15 on Taobao, which is in line with other premium pads. Without independent reviews, it’s hard to know if Coracer’s conductivity claim holds up in real-world testing, but graphene’s reputation does offer some reason for cautious optimism. We tested a similar product, Thermal Grizzly’s KryoSheet, with a conductivity of 7.5 W/m·K, so hopes are high for the GPE-01.
