The Optimus Signature V3 block is the finest CPU block ever created for Intel CPUs, custom designed for LGA 1700 platform models, including the 14900k, 13900k, 12900k CPUs. With the goal of creating the best ever, we went back to the drawing board and redesigned a CPU block from the ground up. New Intel-specific cold plate, revolutionary jet structure and a monolithic metal body worthy of the Signature name. WHY SO GOOD? The biggest reason Optimus blocks are so much better than the competition is because the high heat output in increasingly smaller areas. For example, a GPU die used to output 250w maximum. Now, GPUs have smaller dies but vastly higher heat output at 600w. With the latest CPUs, especially bare die, the actual surface area needing to be cooled is extremely compact. This means the fins directly above the die itself do the majority of the work to cool the CPU. Performance is relatively simple to explain: surface area + flow rate + contact = performance. By having the highest possible surface area directly above the dies, and then increasing the flow rate through the new Signature jet system, plus a highly-specific contact mounting system for Intel, the Optimus Signature V3 is able to remove heat at a faster rate than competing designs.
