PolarFLO provides adequate instructions and really there isn't much to
installing the water blocks. Installing them is much easier than mounting a
gigantic heat sink for air cooling. If you want to see the installation
instructions you can view the PDF documents for the
VGA water block and
CPU water block at the PolarFLO website.
I did run into a bit of an issue when installing the VGA water block though.
The bolts that PolarFLO provided were just barely too large to fit into
the mounting holes on my 6800 Ultra. This was easily fixed by slowly and
carefully boring out the 6800 mounting holes just a bit.

Below are some photos from various angles of the final installation. Some
tubing was changed out later but this is what I essentially ended up with.
Just About Done
Another View Before Leak Testing Begins
You'll notice a vertical length of tubing on the right side of the photos above.
This is what is called a T-Line and it's purpose is threefold. To allow you to
fill and drain the circuit. It's third purpose is to allow for air bubbles to
bleed out while you initially prime the pump, fill the system, and top it off as
needed over time.
Another approach is to use a reservoir instead of a T-Line. I opted for a T-line
as it makes for easier removal and costs less than a reservoir.
The photos below illustrate the filling process.
From priming the pump (letting fluid flow down into the pump) to a circuit basically free of any air
A quick word on the mix I used... As I stated before, I used a 15% mix of the
Prestone antifreeze to 85% distilled water. This broke down to about 2.4 US
tablespoons per 1 cup of distilled water. Once full, there was a total of about
14 fluid ounces in my circuit. I also added just one drop of algaecide. The
particular kind I had suggested 14 drops of the stuff per 50 gallons of water.
So, a single drop was more than enough for my use.

Tons Of Air In The Circuit
Clearer Now That Air Has Bled Out
A little tip...the "frothiness" can be eliminated by waiting to add your
additive to the water after the air has bled out. It's not really a big deal but
it can speed up the filling/bleeding process by an hour or more. Besides,
watching the air bleed out of the T-line is kind of mesmerizing.

Something really worth noting in the photo above is that I found the softer
tubing (Tygon® R-1000 in this case) necessary to make this tight
turn from the CPU to the video card. However, it was only possible by using the
CoolSleeves. Otherwise, the tubing would kink badly. Stiffer tubing would have
required too large of a curve (would have extended outside the side of the case).
CoolSleeves are a real lifesaver that allow you many more options in how you
route your tubing.
