World-class water cooling
Your Obsidian water cooled PC keeps your CPU and GPU at lower temperatures, even under heavy workloads. By using precision-engineered cooling loops, we help your components avoid thermal throttling — so they can sustain higher speeds and maximum performance.
When your CPU or GPU gets too hot, it activates a safety mechanism called thermal throttling, which lowers clock speeds and power usage, meaning fewer frames in games and slower render times.
Water cooled heritage
At Chillblast, we don’t just build water cooled PCs - we’ve been perfecting them for over a decade. We've learned that performance only happens when precision, care and experience come together.
Every Chillblast water cooled PC is hand-built to order, and goes through rigorous testing to make sure it exceeds expectations.
