3-Way Thermal Interface Material Shootout

OCZ Ultra II



OCZ is a relative newcomer in the ranks of the thermal compound market. While they have been making peripherals and components aimed at the enthusiast crowd for some time, they have only recently delved into the making of goop.


Like the Arctic Silver III, OCZ Ultra II consists of a non-silicone blend of polysynthetic oils with a blend of micronized silver. The benefits will be the same as the aforementioned AS3. And while OCZ states that their compound is also not electrically conductive, I would still recommend the same precautions regarding this compound coming into contact with your processor bridges.


Applying the OCZ Ultra II is a simple matter, but the thicker consistency makes it harder to get a smooth coating. Just make sure that you have a thin covering of TIM and you'll be fine. The texture of the compound will allow it to easily fill in any small gaps between the processor core and the heatsink. I found this to be exceptionally good when working with video boards, which tend to have a much larger gap between the GPU/VPU and the heatsink.


OCZ Ultra II comes in 3 gram syringes and should easily cover 25 or more AMD sized processor cores. The added thickness will keep you from getting quite as many applications as other compounds, but there is certainly enough for a large number of jobs. Cost for this TIM is US$5.99 or roughly $2.00/gram.
