Alphacool NexXxoS XP BOLD HIGHFLOW socket 478 (Intel P4) nickel plated

The most powerful semi-impingment water block with backflow channels and extreme flow. The Highflow-models allow extreme flow without taking performance drops - even cooling systems with many blocks are improved with the lowered overall resistance.

If you're using a high performance pump in your system, the pumps power will be used in an optimum way.

The eight backflow channels are spread throughout the pin-structure of the baseplate in an enhanced PCF(c) design and alllow an extremely accelerated transfer of warm water. Additionally, the baseplate repeatedly features channels rotated 90° to give the base plate a pin structure, which has an improved heat transfer in comparison to simple channels. The copper surface is ball burnished which furtherly increases the cooling surface. This patended combination allows a higher cooling performance in comparison to simple semi-impingment blocks or semi-impingment blocks with simply implemented backflow channels.

The flow resistance was further reduced compared to the XP series which results in a very good basis for systems with G 1/4" fittings and systems that are using tubing systems of 10mm inner diameter and up. Due to the internal design of the water block a high utilization of the tubing diameter remains. 53 jets take care of an extremely well balanced and evenly spread distribution of the cooling liquid, 8 backflow channels for an extremely fast discharge of the heated liquid. Even the larges CPU cores of the upcoming processor generations are fully covered this way. The base of the block is flat and polished to facilitate an optimum contact surface for the heat transfer.

XP Highflow X² - means more cooling power and lower CPU Temperature. The middle part of the cooler is now made of nickeld copper for better performace.

By using the existing mounting holes of the motherboard, the block itself is completely visible and recommends itself, especially in combination with 2 5mm LEDs, for case modding purposes.

High grade Röhm / Degussa ® plexiglas is used for the top and the jet unit The block can be eqipped with 2 5mm LEDs for case modding purposes. The G 1/4" threads can be used with any type of fitting. With the enclosed hold down it's not needed to take out the mainboard.
