Alphacool Introduces Shroud & Decoupling for Fans and 24-pin PSU Jumper | TechPowerUp
 
Today, Alphacool presents the Fan Shroud & Decouplers for 120 mm and 140 mm fans, a must have for performance orientated liquid cooling enthusiasts. These silicon shrouds improve the performance of your liquid cooling system by optimising the airflow through the radiator.
 
Alphacool also presents a 24-pin ATX PSU Jumper. This is a simple tool that allows you to power your pump whilst keeping the rest of the system dormant, this is particularly useful when you are filling a liquid cooling loop.
 
The ATX PSU jumper is a really innovative idea in my opinion

 


The "dead spot" under the fan hub is overcome as air pressure builds up between the fan and radiator. The airflow is forced through the fins of the radiator as well as preventing air from escaping through gaps. This in turn also reduces the noise created from the escaping air as well as acting as a decoupler to dampen the vibrations being transmitted from the fan to the radiator and potentially to the case.
