Installing Liquid Pro

Coollaboratory says that you will only need to apply compound to the cooler, and that it is unnecessary but acceptable to apply it to the CPU also. In light of prudence, I opted to apply it to both.

The Liquid Pro manual suggests the use of a Q-Tip, artist's brush, rubber gloves, or the tip of the syringe for spreading the compound. As you can see, I opted for the brush, which seemed to be the easiest option. Thankfully, no “hairs” came loose during installation, but that is always a problem you should look out for when using a brush.

Starting with a clean processor, apply a small drop of Liquid Pro to the processor. The manual says that a small drop will go a surprisingly long way, so I was conservative. At first, the compound only slid around like mercury on your middle school classroom table, but after a bit the bubble of compound started to leak out. I started spreading at the center of the CPU directly above the CPU die because not much heat gets anywhere else on the integrated heat spreader (IHS), and worked my way outwards. It's sometimes hard to tell where you've covered and where you haven't, because the compound is nearly the same color as the IHS, but 15 minutes of endurance did the trick. Something I noticed here that seemed odd to me is that I could not get a flat finish for the life of me, despite the liquid nature of the substance. Adding more proved to be useless, and I had to suck it back up into the syringe. Hopefully the pressure from the cooler will fix this.

The same process follows with the base of your heatsink/waterblock. Start with a small dot, and spread it across. From previous experience with this cooler, I know that the CPU doesn't come into contact with the outer edge of the waterblock, so I only covered the necessary area. As with the CPU, I found it impossible to get a smooth finish on the cooler. Even more, though, is that on the cooler it even felt rough. Something to keep in mind is that Liquid Pro eats through low quality metals, such as aluminum. This means that you will need to have a copper heatsink. CoolIT notes on their website that this waterblock is made of copper, though being silver in color, so I assume that the problems with consistency on the cooler are at the fault of the Liquid Pro, rather than the material of the waterblock. Also, on the waterblock the Liquid Pro did not show any sort of shining qualities as it did on the CPU. At most times when working on the CPU, the compound was mirror-like, however, on the waterblock, it was dull. All said and done, though, I created an acceptable layer on the block. With everything all set to go, what will be the end result? Read on to find out…
