The XSPC RayStorm 750 EX360 has proven to be a stellar PC water cooling kit.

X20 750 Dual Bayres/Pump (Black) V4

The X20 750 Dual Bayres/Pump is a nice looking unit. The all black with the silver XSPC logo really stands out giving the res a hint of class. I have used the clear acrylic version in my personal rig for a while now, and can say that the V4 has made several improvements over its younger versions.

The back of the unit includes a drain port which is a nice added feature. According to XSPC, it can also be used for a temperature sensor as well. The In / Out ports have also had some work done to them. In the earlier versions, the in port lacked any type of protruding thread which left the fitting more in the res itself. Now, the in port equally has a protruding thread that I found to be more stable. Also in the back is the LED holding port, and exit for the pump power cable.

Included with the kit is an ultra bright blue LED. This plugs right into the Dual Bayres/pump allowing a sexy glow through the front panel of the unit.

The mounting holes now have brass or copper threading making the Black V4 even greater than the earlier versions of the unit.

The 1/4″ drain port and LED port up close. Again, nice move XSPC with the drain port.
