OCZ Technology Vendetta 2 CPU HeatsinkOCZ's Vendetta 2 arrived angry and ready to kick some ass. It has the look, but how does it perform under pressure?
When it comes to the absolute best temperatures for your CPU, clearly exotic cooling is the way to go. We've used water coolers mostly and have always found the performance to be impressive. Of course, there are several caveats, such as possible modification requirements for the case, risk of leakage or failure, price and finally the ease of use, or lack thereof.
Air cooling in all those regards holds an edge. Even the most expensive air cooler is going to be cheaper than a quality water cooler. Where you'll need to contend with tubes, wires, blocks and of course water, with air cooling, it's usually just the heatsink, fan and a couple clips. There are pros and cons for both of course, but for the majority of users, air does the job just fine.
OCZ Technology Vendetta 2
OCZ's Vendetta 2 arrived in a branded box with the CPU fan as the predominant object through the box window. The specifications run along the sides of the box and outline all the features as well as compatibility.
Our particular review unit supports all AMD and Intel CPUs except for the new Intel Core i7 CPU. A new mounting bracket was in development and not available at the time of testing. It is ready now however. .
A power adapter is included if your motherboard header cannot handle 0.13A. A non-silicone blister pack of paste is also part of the package, which will do the job for most people.
While not the largest cooler we have seen, the OCZ Vendetta 2 is no tiny low-profile heatsink. The Vendetta 2 measures 120mm x 50mm x 159mm (width x depth x height) without the fan. We don't have an exact weight, but despite the size, the Vendetta 2 is not very heavy, thus not requiring any special heatsink bracket to secure the cooler. As such, this also makes installation quicker and less troublesome as you will not need to remove your motherboard. Of course, this is assuming that the previous cooler did not have a custom bracket.
The heatsink fins on the Vendetta 2 are 100% aluminum based. There are 50 fins in all, each separated (or secured depending on how you look at it) with a this strip of aluminum. Aluminum is a great heat dissipater and as it is not expensive, keeps the costs low. Furthermore, it does not weigh as much as copper, thus keeping the weight manageable. Each fin, as evidenced in the picture below, have dimples.
The idea here is in order to maximize cooling, total surface area is only part of the equation. As we've seen with water cooling blocks, turbulence is needed in order to optimize flow. In this case, we are talking about the air. The dimples force the air to move and change direction as it passes through the fins. The air will slow down in some areas
There are 3 copper heat pipes that run through the Vendetta 2.
The heatpipes are designed to move heat away from the CPU, and through the fins where they are cooled by the fan. While this technology may not be new to some of you, OCZ does employ a different technique some of you may not be familiar with.
OCZ uses heat pipe direct touch (HDT) which exposes the heat pipes directly to the CPU. In theory, this will be more efficient than having the heat move through the base to get to the heat pipes. Here is a quote from OCZ:
Utilizing the proven performance of the latest HTD design, the Vendetta 2 has direct contact with the processor using three copper heat pipes to ensure the most rapid heat transfer and a lighter weight.
The Vendetta 2 package includes a 120mm fan. The fan power draw is 12V DC 0.13A. At its peak, the fan can spin 1500 rpm, which works out to 81 CFM, 32 dBA. At it's lowest, it spins at 800 rpm which generates a flow of 65 CFM and 20 dBA. The fan is a 4 pin design with PWN which can allow your motherboard to automatically adjust the fan speeds based on settings ou'll need to configure in the BIOS or board software.
