The Hidden Danger in Your PC Build
While most PC enthusiasts focus on selecting the right processor, graphics card, and cooling solution, few consider that something as seemingly innocuous as thermal paste could potentially destroy their entire system. Recent investigations have uncovered that one particular thermal compound is causing unprecedented damage to CPUs and heatsinks through chemical corrosion and bonding issues that render components unusable., according to market insights

Understanding the Corrosion Mechanism
According to detailed analysis by PC hardware investigator Igor Wallossek of IgorsLab, the problematic SGT-4 thermal paste manufactured by South Korean company Amech contains an unstable chemical formulation that actively damages computer hardware. The product uses an acetoxy-crosslinked RTV silicone base with methyltriacetoxysilane as a key additive – a compound that releases acetic acid when exposed to atmospheric moisture.
This chemical reaction creates multiple failure points: The released acetic acid corrodes copper and other metal surfaces, creating pitting that compromises thermal transfer efficiency. Simultaneously, the paste undergoes partial cross-linking that causes it to harden over time, effectively bonding the CPU to the heatsink with what Wallossek describes as “an immense separating force” required to separate the components., according to related news
User Reports Confirm Widespread Issues
The problems extend beyond laboratory findings, with numerous users on South Korean technical forum Quasar Zone reporting identical experiences. Complaints describe CPUs permanently fused to coolers, distinctive vinegar-like odors emanating from systems, and visible corrosion on both processor heat spreaders and heatsink bases. Metallurgy experts examining affected components have corroborated Wallossek’s technical analysis of the chemical damage.
“What makes this situation particularly concerning,” notes one hardware technician who reviewed multiple damaged systems, “is that the corrosion creates micro-pitting that increases thermal resistance while simultaneously creating a mechanical bond that risks destroying the CPU during cooler removal.”, according to related news
Manufacturer Response Raises Red Flags
Rather than addressing the technical concerns, Amech has dismissed all reports as baseless while failing to provide substantive counter-evidence. The company’s response has included personal attacks against critics and references to environmental certifications that have no bearing on the corrosion issues. Compounding these concerns is the company’s questionable business presence – Amech lacks an official website, professional email domain, or verifiable physical address., as additional insights
The origins of the SGT-4 formula remain unclear, with speculation about whether it represents an improperly tested domestic development or a rebranded product from another market with inadequate quality control.
Protecting Your System: Safer Alternatives
For builders seeking reliable thermal solutions, several proven products deliver excellent performance without corrosion risks:
- Thermal Grizzly Kryonaut: High-performance paste renowned for stability and exceptional thermal conductivity
- Arctic MX-6: Recent formulation offering improved longevity and thermal transfer characteristics
- Noctua NT-H2: Trusted compound balancing ease of application with consistent long-term performance
Due Diligence for Component Selection
This situation highlights the importance of researching even seemingly minor components in system builds. The SGT-4’s concerning availability on major platforms like Amazon and Newegg – complete with deceptively positive ratings – demonstrates how easily problematic products can reach consumers. Before purchasing any thermal interface material, verify independent technical reviews and consider the manufacturer’s reputation and transparency.
The thermal paste market contains numerous excellent products from established manufacturers with proven track records. While new entrants can bring innovation, this case illustrates why thorough testing and chemical compatibility verification remain essential before introducing any new thermal compound to sensitive computer components.
