A Closer Look



The Vendetta is configured with the fan and radiator perpendicular to the motherboard. The cooling fins are of very thin aluminum in a shiny brushed finish, with the OCZ logo stamped into the uppermost fin. The cooler itself is relatively lightweight, a little lighter than the last couple of similarly designed coolers I have owned.

Notice the surface of the fins. They have “dimples” punched into them, which not only adds to the fins' surface area, but according to OCZ, creates wind turbulence which reduces the ”skin effect” of laminar air flow. Also, the folded “V” shape of the fins adds additional surface area without increasing the overall size of the radiator.

Missing from the Vendetta are any provisions for directing much if any air towards the motherboard. Passive heatpipe chipset cooling is growing more and more popular, and the popular location for the radiators is around the CPU. Heatsinks configured with the fan parallel to the motherboard, such as the stock Intel cooler, blows 100% of their air towards these coolers. Some that are configured with the fan perpendicular to the motherboard have a portion of the exhaust air directed towards the rear of the motherboard. The Vendetta directs 100% of exhaust air towards the rear case fan. My particular case has an internal 120mm fan I have directed towards my passive motherboard cooling, but most cases don't.



Included with the Vendetta is a 92mm fan. I thought that 92mm was a pretty silly size for a case fan, but I feel that it makes the ideal sized fan for a CPU cooler. With 39-54.6 CFM @ 22-34 dBA, the fan has a pretty good noise-to-airflow ratio. It has a 4-pin PWM power connector that is designed to work with a 3-pin bus if needed.

The power wires aren't sleeved... which would be nice, but my last few coolers haven't been sleeved either.



As I mentioned earlier, the base is designed so that the three heatpipes will directly touch the CPU's heatspreader. I'm not a thermal engineer, but I do realize that there is some efficiency loss when transferring heat from one substrate to another, such as from the heatsink base to the heatpipes contained within. Also, allowing the heatpipes to directly touch the surface gives you the superior heat transferal properties of copper where it needs to be, rather than using a less efficient but much lighter aluminum base with copper heatpipes running through it.

The base surface and heatpipes have been lapped. Not a mirror finish, but better than many coolers I have seen recently.



Included is hardware for mounting Intel LGA 775 and AMD Socket 754/755/939/AM2. OCZ warns that there may be some LGA 775 motherboards out there that the Vendetta may not fit. Also included are rubber mounts for the fan, a 4-pin Molex to 3-pin male fan adapter, thermal compound and a well written and illustrated instruction booklet.

Let's get the Vendetta in a rig!
