Installation: Mounting The Blocks

Included in the WB4 Gold heatsink kit is mounting solutions for socket 478/775 AM2/754/939 and 940. The WB4 Gold takes advantage of the stock socket 478 heatsink retention system so there is no need to remove the motherboard. Two aluminum rails are placed through the holes in the stock mounting system, spring clips are screwed to the waterblock, and the assembly is screwed to the rails. Zalman features excellent flash installation videos on their website for most of their products. When fastening the WB4 I did notice that the spring tension was quite extreme. In fact, the spring tension was so great the aluminum rails had started to flex. But the instructions did specify to tighten until the screws bottom.


The GWB3 uses a new style of retention system which allows it to support its plethora of mounting options. Instead of a single spring clip, the GWB3 uses 2 or 4 springs fastened with nuts on the back of the card. This mounting solution has proven to be more stable when mounted on the card. Kudos to Zalman for the swivel barbs. I'd also like to mention with the availability of the ZM-RWB1 GPU RAM waterblock (optional), ramsinks are not included with the Reserator 2 kit.

Nothing in the NWB1 Northbridge block has changed but I wanted a better mounting method. Out came the zip ties. I used the spring clip that came with the kit, but used the zip ties to put some actual force on the waterblock to hold it down properly.



With the blocks mounted, it's time to route the hose. I'll share a tip with you that might come in handy when trying to get your hose lengths exactly even when you're done. Obviously you're going to need a few short pieces to connect the cpu to the northbridge and the northbridge to the gpu. Go ahead and cut those small pieces off one end of the hose. With those two pieces installed, route both hose ends through the backing plate and connect them to the gpu and cpu block. Your longest length of hose should now complete the circuit. Pull the hose snug from the back of the case and when you find the middle, cut it. Now you've connected everything you need to inside, and both pieces coming out of the case are exactly even.

Bleeding The System:

When I first opened up the package and saw the degassing tube with the quick coupler ends already installed I couldn't help but say, "Huh? What the heck is that for!?" Zalman saw this coming and put a sticker on the tube that says, "Refer to Users Manual." Simply put, it's for bleeding the Reserator 2 unit itself before it's attached to the rest of the cooling system. Cake right? But the Reserator 2 now uses a relay to turn itself on so it must be connected to a PC, or spare power supply if you have one lying around. Zalman includes a jumper cable and instructs you to remove the main ATX power cable from the motherboard and insert to jumper. When the PC is plugged in it will trigger the Reserator 2 to turn on, but leave your system off. After a minute or so of cycling the power on and off to ensure there were no bubbles left over we are ready to connect the rest of the system.

We'll fire up some tests on the next page.
