Stinky thermal paste emits acidic vapors, corrodes copper, 'glues' heatsinks to processors, and permanently damages coolers - SGT-4 TIM is a chemically reactive blend, finds investigation

Amech (Aimac) SGT-4 thermal paste, popular for being cheap, is found to emit acidic vapors that damage CPUs and coolers, causing pitting and corrosion. The paste's chemical composition includes a reactive substance that releases acetic acid, leading to metal oxidation and poor thermal conductivity. Despite user complaints and evidence of damage, the manufacturer, Amech, dismissed claims and insulted critics, causing a loss of trust in the company. The paste's composition remains undisclosed, and certifications like RoHS and REACH do not address its corrosive nature under normal usage conditions.
