Liquid-Cooled ATX Build in Corsair 4000D

A 240mm liquid cooler handles the CPU thermal load inside a Corsair 4000D tempered-glass chassis. The PRIME X870-P motherboard provides four M.2 slots, two USB4 ports at 40Gbps, Intel 2.5Gb Ethernet and Wi-Fi 7 connectivity. An 850W 80 PLUS Bronze power supply delivers stable power for the complete configuration.

Sustained Load Thermal and Power Behaviour

The 240mm quiet-edition liquid cooler and 140mm PSU fan are designed to maintain lower temperatures during extended compute sessions. The 850W Bronze-rated unit supplies continuous power with over-voltage, under-voltage and short-circuit protection. This cooling and power arrangement supports long rendering or compile jobs without thermal throttling.

Questions about this item

Will the 240 mm liquid cooler keep the 12-core Ryzen 9 9900X3D from throttling during long renders?

The 240 mm Quiet Edition AIO is designed for the 12-core CPU and its 4.4 GHz base clock, but sustained all-core loads near the 5.50 GHz boost will eventually hit the radiator's thermal limit.

How loud does the system get when the RTX 5070 and CPU run flat-out for hours?

The case uses a 140 mm PSU fan and a Quiet Edition pump; under full GPU and CPU load the combined airflow noise rises noticeably but stays in the low-decibel range for a workstation-class build.

Which display cables must I already own to use the RTX 5070's video outputs?

The RTX 5070 connects via PCI Express x16 and provides standard DisplayPort and HDMI ports, so have the matching DisplayPort or HDMI cables ready for your monitor.
