OCZ Dominator II CU
The old Dominator II from OCZ was a workable mid-range cooling solution for the AMD line of processors, but that just wasn't good enough. So we take the old design, add a few features, and then make it run quiet as a mouse. Does it work? We'll see soon enough.
The heatsink is made out of aluminum and measures 62mm x 63mm x 35mm. While this may seem rather small in stature, it does have a trick up its sleeve that bears mentioning.
Can you see the rough texturing of the fins? This is called Textured Fin Technology and helps provide added surface area to help in cooling. If you'll remember the basics of good cooling, one of the components is a higher amount of surface area. While small, this cooler may still end up being a workable solution because of this textured finish.
Time for another EEK! After removing the thermal tape, I was left with a smooth working area, but not the polished finish that some use. For those who lap, you'll need to do just a bit of sanding to get it smooth, but not much.
The front clip used is like many others that I have seen, but it didn't take that much effort to get it installed. This is unusual with this type of a clipping mechanism. Most of the other models that use this style of single lug design require a goodly amount of effort to install it to the socket, but not so with this one. But even with a lower amount of required force, the sink was still securely in place once attached.
Here is something that is interesting, a retention for the rear clip. I can't even think of how many times that I have had to fight like crazy to get the rear clip(s) mounted to the back side of the socket. This little innovation made it a very simple task since the back clip is help firmly in place to allow for easy mounting.
This smallish fan is what powers the Dominator II CU HSF. Not only is it one of the slimline models, it is also the smallest fan in those tested. It measures in at a meager 60mm x 60mm x 10mm, spins at 5,300RPM and puts out about 25-CFM airflow from its small body. So even though it is the smallest, it is not the lowest producing fan in our tests.
A quick item of note: OCZ rates this fan at 40dBA for sound output, but I'm not sure that I can buy into this. I have tested other fans with lower decibel ratings that I can still hear in my system. I could not hear a thing of this fan when the system booted up or while it was running. I'm betting that the sound rating will be considerably lower than the rated stats.
