Cool to the Core

Effective content creation demands a reliable, professional foundation. Prime TRX40-Pro S is engineered with multiple onboard heatsinks and an array of hybrid fan headers to ensure your rig stays cool and stable under intense workloads, so that your focus remains fixed on your creative goals.

M.2 Heatsink

Two M.2 slots are covered by a massive heatsink to combat temperature-induced throttling that can affect performance during heavy, sustained storage loads.

Removable captive screws reduce risk of drops or losses during heatsink removal

VRM Heatsink and Thermal Pads

A massive VRM heatsink and high-quality thermal pads enhance heat transfer from the MOSFETs and chokes for better cooling performance. A fan holder is bundled for additional cooling options.

SoC VRM Heatsink

Prime TRX40-Pro S features an SoC VRM heatsink, positioned in the pathway of the chipset fan's airflow, to enable the SoC VRM to stay cool during memory overclocking.

Active Chipset Heatsink Solution

Dedicated Cooling for Unthrottled Transfers

PCIe 4.0 provides twice the bandwidth for data flowing through the chipset, which creates more heat than the previous generation. Prime TRX40-Pro S features an actively cooled heatsink to prevent throttling during sustained transfers, designed with the screws on top for easy access and maintenance.

Active Chipset Heatsink Solution includes:

  • Air Duct: A specially-designed air duct helps the fan generate static pressure and concentrates air flow over the fins.
  • Finned Heatsink: The heatsink fin density is optimized to maximize surface area while maintaining a low-resistance exhaust path.
  • Custom Delta Superflo Fan: The custom low-noise fan features a high-durability bearing with a 60,000-hour L10* lifespan, while its speed is easily adjusted via Fan Xpert 4 or the UEFI.

* L10 bearing life is a standard metric that specifies the number of hours that 90% of the bearing are expected to continue successfully operating, as a minimum.
