OCZ Dominator HSF Review

Testing for this sink followed my normal guidelines so that I can have results that are fairly compared to other heatsinks without bias. Ambient temperature during testing was 21-22C, voltage was set to 1.80 volts and the test system consisted of:


Antec SX1030 Tower Case


AMD Thunderbird 1000 (AVIA)


Abit KT7A-RAID Motherboard


256MB Crucial PC133 CAS2 SDRAM


Arctic Silver Thermal Compound


Prolink XX-Player GeForce3


Temperatures were taken at stock speed, again at 1100MHz, and a final time at 1333MHz. This will give us an idea as to the effectiveness of the sink during both normal, moderate and aggressive clock speeds. The 1333MHz speed testing is a new one that I have incorporated, but with the 1GHz processors and above going to much higher levels, it seemed necessary to see what coolers would be effective when these processors are pushed to these higher limits.


Testing itself included measuring the temperature at idle, after a Quake III Deathmatch battle, and again after a continuous looping of MadOnion's 3dMark2001 Demo. These are the same testing criteria that I have been using in the past, so am maintaining some consistency for the sake of comparison.


As I stated earlier, I wasn't really expecting too much from this aluminum beast. With most manufacturers trying their best to make better copper units, it almost seems a step backward to revert to an aluminum model. But I think you'll be surprised at its performance. I know that I was. So to satisfy your curiosity, lets get down to some serious benchmarking…


- 1000MHz (57.4 Watts)





Its looking like that new textured fin technology is paying off in spades here. I am getting constant results that are outperforming some of the best selling copper sinks on the market today! If this keeps up, we're going to have something do some rethinking on the topic of heatsink material. But can it keep up this pace? Let's see…


- 1100MHz (62.2 Watts)





OK...Tell me again why we want a copper heatsink? To better dissipate heat? Hmm…


As I told you earlier, the results will surprise you. The performance has been not only on par with the copper sinks out there, but in many cases it has surpassed them altogether. And to think that this heatsink was made for those who are budget-conscious too. But before we rant, let's see how the Dominator hangs with a 33% overclock of the processor…


- 1333MHz (73.6 Watts)



WOW! The Dominator was able to handle the stress all right. It handled it as well as the Dragon Orb, and that is a pretty decent sink too. Not too shabby considering that aluminum has all but been tossed out the window as a viable material to make heatsinks from anymore. So lets wrap it up…
