coolant

Master overclocker Roman "Der8auer" Hartung has demonstrated a spray cooling technique for the AMD Ryzen 7 9800X3D, which involves applying coolant directly to the CPU's integrated heat spreader (IHS). This method, a variant of phase-change cooling, allows the coolant to transition from liquid to gas upon contact with the heated CPU, effectively removing thermal energy. Der8auer used 3M Novec 7000 coolant, which has a boiling point of 34°C, although it will be banned in the EU later this year. The experiment consumed approximately 500ml of coolant in 15 minutes, maintaining CPU temperatures between 60-70°C during light workloads and completing the Cinebench multi-core test.
