Testbench
We have proven that AIO and Water Cooling Systems and excessive use of case coolers are completely unnecessary on modern computers, unless you are working inside a 90° Celsius Sauna room.
Modern Hardware is much more Energy and Thermal efficient than 10 years ago, some CPUs are also made to withstand higher temperatures of up to 115°C.
Some Brands around the world do that to make the cases look Premium or fancy to justify a 50% price increase on usually outdated hardware.
As proven with out machines, not even case coolers are necessary, even under heavy load all components work under 80°C.

RAM overcklocking is completely useless, the system may become unstable and even slower on some cases, because the system runs out of synchronization. Even when done right, the performance boost is just around 2%, for 20% more power consumption!
Not overclocked RAM Voltage: 1.10V
Overclocked RAM Voltage: 1.35V to 1.40V
Our tests show it's not worth it.
What makes a difference on the overall system speed is the combination of a very good motherboard, CPU, GPU, RAM, M2 NVMe SSD, latest PCIe Versions and a very reliable PSU.
Motherboards and CPUs have their own specifications on which RAM speeds are supported and how many PCIe Lanes they can run.
If a machine has the latest motherboard but a CPU from 4 Generations behind, running a RTX 4060 and a PCIe 4.0 M2 NVMe SSD, you are not using the full potential of your machine. Since PCIe 5.0 doubles the read and write speeds of your M2 SDD, loading that much faster than with a PCIe 4.0.
The same applies if the Motherboard is not the latest model, not supporting PCIe 5.0, but you have a RTX 5060 or 5090, which has faster speeds (PCIe 5.0) than your motherboard or CPU supports, that means the GPU will not be able to deliver full power and you might be losing around 50% FPS and Graphic Power.
Also if the CPU supports only 16 or 18 PCIe 5.0 lanes, but you are using already 16 Lanes on the GPU + 4 Lanes on the M2 NVMe SSD, which means, one or another is not working at full potential because the CPU can't manage the 20 Lanes or more you need.
Our Machines are carefully designed to reach the full potential.
We don't sell trash, i7, i9, AM4, Ryzen 7, PCIe 4.0, GDDR6, are all outdated hardware.
