Introduction

Even though OCZ may not have the best customer services the fact that they make good products still remains. OCZ makes high quality products for overclocking and cooling purposes and I still use an OCZ Gladiator on my server. Now Let’s take a look at the OCZ Dominator² Heatsink

Here is a front shot of the Dominator as you can see the fan is taller than the base of the heatsink.  Here’s a side shot of the heatsink, you can see the clip and the fins, which we will look at in more detail in a minute.  I took the fan off to reveal the shroud and the fins, there are 46 Micro fins, which help dissipate heat.  I then removed the shroud, which is attached by 4 small screws; the shroud helps direct the air directly onto the heatsink without losing pressure.

Underneath the shroud the heatsink has a portion of the fins on both sides removed so the shroud can fit properly, the picture is not that great, however you can see on the right side how the fins are textured, the textured fins is a technology that is supposed to increase the heat dissipation.


The clip looks to be of good design, you do not need a screwdriver. We will see later if it works well or not.

The base of the Dominator² is pretty well finished however there are noticeable swirl marks on the bottom; OCZ could have done a better job finishing it. You can always lap the heatsink which will most likely improve the overall performance.

The fan has a 4 pin connector for the power and also has a 3 pin connection which you can attach to one of your motherboard headers to monitor RPMs, this is a really nice feature which I think more high powered fans that cannot be hooked to a motherboard header should use. Here are the specs of the fan.

  • Dimensions: 60x60x25
  • Air Flow: 40CFM
  • Speed: 6800RPM
  • Noise: 48.2 dB
