The Dragon F1 Gemini
This is arguably the best-designed CPU pot on the market today. The Gemini sells at KPC for only $225. This is the 3rd generation of the Dragon line, and is the first to employ KPC’s new modular design. This allows for user-switchable base, with two bases included in the price. Having a modular base has helped lower the price by cutting down the manufacturing cost, but the main purpose is to allow for flexibility. For instance, the FAST base, which is also known as “slayer,” has a large surface area for maximum contact with the LN2, and is perfect for use with AMD CPUs which do not exhibit any of the so-called “cold bug” behavior. The SLOW base has less surface area but more mass, which allows for easier temperature control when overclocking a CPU with a cold bug.
The FAST base
We tested the fast base on an AMD Thuban six-core CPU. Unique to modern AMD CPUs is their ability to operate at temperatures approaching absolute zero, as has been demonstrated on several occasions by famous overclockers (including k|ngp|n himself) pushing the Phenom II architecture to extreme speeds using liquid helium, which has a boiling point of -246C. [Note: The Gemini is not designed for use with liquid helium.] However, when overclocking Phenom II using liquid nitrogen, the goal is obviously to keep the CPU as cold as possible. In order to accomplish this, a container with a very large surface area is very important, so that the liquid nitrogen has a larger potential for heat dissipation. With the FAST base, we were able to keep the AMD Phenom II X6 CPU very close to the temperature of the LN2, even when running a very high load test like wPrime 1024M.
The SLOW base
We tested the SLOW base with several Gulftown-based CPUs. These chips are monsters, and generate a tremendous amount of heat when pushed to their limits, but also typically suffer from CB and the cold boot bug (“CBB”) tendencies. So, to properly push these CPUs to extreme levels, it’s essential to be able to accurately control the temperature of the CPU to avoid the danger zones where the CPU could lock up during or after a benchmark. With a smaller surface area and slightly more mass, the SLOW base reacts slower to LN2 as it’s applied, and temperature swing is minimized.
