4-Way GPU Water Block Roundup
 

* Zern GPU [ GRAKAWAK ] of Zern
* NexXxos GP2X-Pro [ GP2Xpro ] of Alphacool
* MCW 55 [ Baswi ] of Swiftech
* Cool Matic X800-850 [ Gpu+ram 1.0 ] of Innovatek

The goal of this comparative test n’est not to find the number one of the waterblock, but primarily to emphasize which is that which with the best report/ratio price quality.
Of course there is of them inevitably one which dissociates batch, but you will see that the results are very surprising.
