Deepcool Upgrades AIO CPU Cooler With 'Anti-Leak' Pressure Bag

Deepcool this week announced an updated version of the popular Castle 240 RGB AIO CPU cooler and added a new anti-leak feature said to minimize the chances of leaking caused by internal pressure changes created by the liquid’s temperature. The Deepcool Castle 240 RGB V2 uses an internal bladder that expands and contracts, thus reducing pressure buildup. 

This new technology works by using a pre-installed elastic pressure relief “bag” inserted on the cold side of the radiator. The bag is added with one side exposed to the air and the other side submerged in the coolant. When the pressure inside exceeds atmospheric pressure, the bag is squeezed increasing the internal volume and lowering internal pressure. Deepcool said this reduces the risk of leakage due to expansion of the coolant). We can’t speak as to how much the pressure changes internally or how much this is really needed, but any mitigation to leaks is welcomed.
