Introduction
Oreo is an ATX, standard form factor computer based on the AMD X870E chipset and represents the best in extreme gaming performance and accelerated content creation. It was designed and built on the ROG Crosshair X870E Apex motherboard for its supreme PCB quality, power stage design, extreme CPU overclocking potential and memory signal integrity. At its heart, it is powered by a binned and delidded 16-core, 32-thread AMD Ryzen 9 9950X3D with an overclock of 5.6GHz on the 3D V-Cache cores and 5.8GHz on the non-3D frequency cores with an FCLK overclock of 2200MHz.
It is paired with an NVIDIA RTX 4090 Founders Edition with an overclock of 3.0GHz and features 64GB of binned G.SKILL Trident Z5 Neo (F5-6000J2636G32GX2-TZ5NRW) memory, each paired with an IceManCooler ICE-HSG full copper water block allowing for an overclock of 6400MHz C26 in 1:1 mode @1.65v (24-12-36-30) with completely fine tuned sub-timings and turn around timings for the absolute lowest latency and highest bandwidth at the given clock speed.
Storage
For the operating system, it uses a Western Digital Black SN850X 1TB NVMe SSD and secondary Western Digital Black SN850X 8TB NVMe SSD for storage, both operating at 7.3GB/sec.
Airflow and Cooling
Airflow is handled by a hybrid array of 15 individually controlled fans. Intake is provided by 9 Noctua Chromax NF-A12x25 120mm fans and an additional 6 Noctua Chromax NF-S12A 120mm fans for exhaust. This setup requires the use of two Corsair Commander Core XTs for precise individual fan curve control, pump control and liquid temperature monitoring as well as full RGB control throughout the computer case.
Responsive fan and pump control is crucial when it comes to regulating the amount of heat moved away from the Thermal Grizzly AM5 Mycro Direct-Die water block. Fluid flow is driven by a 375mL Heatkiller Tube 150 D5 MP paired with Heatkiller's WCP D5-PWM pump. It is dynamically controlled by one of the dual Corsair Commander Core XT devices based on the coolant's temperature with a maximum of speed of 4800RPM at 35c liquid.
The top 360mm x 55mm Heatkiller RAD 360-L radiator is set to intake cold air directly from outside of the case and is setup in a 6-fan push-pull configuration while bottom 360mm x 35mm Heatkiller RAD 360-S radiator is only setup in a 3-fan push configuration, up through the radiator and into the GPU. After exiting through the back and top of the GPU, the air then meets in the middle of the case and is then exhausted out of either the back of the case or the side of the case.
All exhaust fans are exclusively controlled by the GPU and idle at 0 RPM when the GPU is below 50c. The exhaust fans will only reach their max RPM should the GPU reach 70c. With this dual fan controller configuration, the system can remain exceptionally silent at idle, during moderate productivity use and during light gaming workload.
Conclusion
Oreo aims to be a quiet, efficient and no-compromise 16-core workstation and 4K 240Hz gaming machine designed to be expanded upon indefinitely.
