Our Engineered Solutions
Engineered for Optimal Heat Transfer and Safety
Calibrated Spring Tension
Our spring-loaded combination screws deliver precise, constant clamping force, protecting delicate CPUs/GPUs while optimizing the thermal transfer rate.
Captive Design for Safety
Specialized captive screws remain permanently attached to the thermal module even when unthreaded, eliminating the risk of losing hardware inside the PC chassis.
Anti-Vibration Fan Mounting
Hardware engineered to secure high-speed cooling fans and blowers, absorbing vibration and preventing acoustic noise or loosening.
0.05mm Precision Standoffs
Custom CNC-machined standoffs and positioning pins that maintain exact height clearances between the heat sink and the motherboard.

FAQ
They provide a calibrated, constant pressure against the chip. This prevents overtightening (which can crack the silicon die) while ensuring optimal compression of the thermal paste/pad for maximum heat transfer.
A captive screw is designed to stay attached to the thermal module even when unscrewed from the motherboard. This prevents tiny screws from dropping into a dense server chassis, which could cause fatal short circuits.
