Zaward Vapor 120

First off, let’s open the assembly/installation bag. Displaying everything out, we have the appropriate mounting hardware, CPU back plates, fan wire brackets, a minuscule tube of thermal compound, a complete picture-by-picture installation sheet, and a hex key.

Pulling the fan out, the first thing that would catch anyone’s eye is the unique “Golf fan” design. I could see it possible that the extra dimples could catch more air, thus improving air flow. It also might have something to do with the rated 93.96 CFM.

Moving in closer to the actual connection of the fan, we see that it uses a 4-pin PWM, with a braided rubber sheath around the wires for protection.

Now for the heat sink, here’s a quick full-profile shot.

Now, looking straight in from the front, we immediately see an anomaly in the heat sink; the “bumps”. These bumps are in fact the dimples punched in at measured intervals, resulting in 33 dimples on 51 of the 52 fins. That’s a total of 1683 dimples packed in here. We’ll see shortly if they do their job or not.

Getting a closer shot at the dimples themselves, we can see that they have a small hole in the center. The benefit of the dimples is an interesting concept; they cause a pressure drop, resulting in increased turbulence, which in turn increases heat transfer.

Rotating the heat sink 90 degrees, we see that the Vapor 120 is much slimmer than the typical heat sink, being barely any wider than the base itself. As well, we see the sides of the fins turned down. Why you may ask? It helps with directing air flow, and as I luckily found out it also prevent the fins from bending at the ends; it makes a sort of “stack effect”.

Flipping the heat sink bottom-up, I peeled the “Please remove before installation” sticker covering the base. Under, we have a very clean aluminum and copper base. Placing a level on the surface, it comes across as perfectly flat. Placing the blue tack on the surface, we can see the clarity of its reflection; not mirror clean, but obviously smooth enough to make some reflection. This has the potential to be better, but I’m going to let it pass due to its above-average quality.
