Final Words

Those who want the best in air cooling will not be satisfied with either the OCZ Vendetta or the Scythe Kama Cross coolers. However, since neither cooler is aimed at or priced like the top of the air cooling heap, it is unfair to measure their worth by the top standards. As midrange air coolers their worth should be measured by midrange expectations.

So what do we expect in a midrange cooler? We certainly don't expect the top overclock to be the same, but it should not be far from the best. We expect cooling performance to scale well, paralleling the curves of the top coolers tested at slightly lower performance levels. Price should be low enough, compared to the top coolers, to make the compromises palatable. Finally, a standout feature like smaller size, lower weight, and easier mounting would give cooler shoppers a reason to choose the midrange cooler instead. Something like an innovative and effective new design that makes the cooler stand out from the crowd could also make a cooler a reasonable option.

With these criteria how do the OCZ Vendetta and Scythe Kama Cross measure up to our midrange expectations? They both excel in some areas and unfortunately fall short in others.

The Scythe Kama Cross is frankly a disappointment. The design is very innovative with the X aimed at combining the best of heatpipe towers and down facing cooling. Unfortunately, it provides the worst of each feature and ends up being barely better in performance than an Intel retail cooler. At a price of $40, recently reduced to $30 at most web etailers, it does not compare well to the zero cost of Intel retail, or $50 to $70 for the Tuniq, Scythe Infinity, and Thermalrights that significantly outperform this cooler.

Even a terrific 120mm fan like the Scythe S-FLEX can't do much to improve the mediocre performance of the Kama Cross. The cooler is also large, but not particularly heavy, and installation with the push-pins can be a challenge in most cases. So, unless you are in love with the interesting and funky looks of this "Gen-X" cooler, which we can actually understand, it is best to choose another midrange cooler.

The OCZ Vendetta is a different story. The cooler is much smaller than the usual top 120mm side-fan heatpipe towers, and the Vendetta is also much lighter. You can find it on sale for around $30 and performance mirrors the top coolers we have tested at AnandTech, with just slightly lower cooling capabilities. Even the overclock is an acceptable 3.87GHz with a small 92mm fan. This matches the entry-level water cooling systems we have tested. Installation is also a snap, the mount is easy to install, and the only "gotcha" is the wobbly push-pins. We can live with that as you only mount it once for most users, but we do hope OCZ or Xigmatek can improve the push-pins with a minor update to the Intel 775 mount.

We would also prefer that the Vendetta be able to mount a larger 120mm fan. However, the 92mm is okay in performance at the highest speed. Unfortunately, the highest speed of the fan also measures much noisier than the specifications for the cooler. If you want performance and silence you will need to mount another 92mm like those we recommended on page six.

We really do like the elastomeric mounting straps and the innovative design for using them to mount the fan. We just wish the completed Vendetta cooler was as quiet as promised. If noise is not a major worry for you the Vendetta is fine as is, but you will need to run at lower fan speeds and lower overclocks or install a new and better fan if you want to overclock and sleep next to your computer.

Overall, we would pass on the Kama Cross unless very low noise and a conversation-piece design are the main objectives. However, the OCZ Vendetta is a very good value in midrange cooling. For around $30 it matches the performance of entry-level water cooling at a much lower price. This is enough savings to forgive the minor performance reductions you get with this smaller cooler. The good news is the cooling scaling behaves exactly like the very best coolers, and performance is predictable and very competitive.

If the noise of the Vendetta can be solved with a replacement fan it can be a near-ideal midrange cooler. With more competitive noise performance the Vendetta would be an easy recommendation from AnandTech at its current price point. Even with the current noise issues it is still a very good performer for the money and a very good buy.

    Spend the extra $20-30 and get the Thermalright Ultra 120 Extreme. Of all the places to cut corners and save money this is really where it counts to protect your cpu and allow for decent overclocks.

    As always, it was a nice read, but why oh why would you plot the 2 graphs on page 7 in that manner? Seems funny to me to have the points on the graphs "drop" as the temperature raises... I guess thats just my .02
  • Wesley Fink - Tuesday, October 2, 2007 - link

    It's very easy to change the chart with temp going up if enough readers prefer it. We changed the graph scale after receiving several complaints that the top performance was the lowest chart position on the old charts and difficult to comprehend. If more readers prefer the original chart layout we will be happy to change back. Please let us know.

    I prefer the old orientation, as it makes sense to me that when you are looking for the cooler with the lowest temperature, you look at the lowest point on the graph.

    Pretty acceptable for the OCZ cooler. I wonder how it would perform inside an enclosure like the X-Qpack. I'm trying to build a nice gaming rig with the X-Qpack and would like to see if it would fit inside.

    Depends on your skill with a hammer and chisel: The X-Qpack (and X-Qpack2 and Ultra Micro Fly) only have about 75mm of headroom above the CPU -- challenging for a 92mm fam mounted perhaps 40mm above the CPU! Go with a Zalman horizontal flower (7000, 7700, 8700), a few other units or just the stock fan in those cases.

    PS: The X-Qpack2 has improved airflow and clearance (length) over the X-Qpack.

    StorageReview just did a review of the http://www.storagereview.com/1000.sr">Western Digital "Green Power" 1 TB hard drive. While it's not the best performing drive in the world, it's no slouch, and it has the side effect of being the quietest drive they've ever tested. (Plus it runs cool enough that you could probably slap it in a

    It seems utterly ridiculous to me that these coolers are tested on dual setups.
    If someone looking to build a quad is trying to find useful information, this review is completely pointless.

    A test on a quad however will still provide useful info to someone building a dual core.

    The defence that games don't use quads yet is also totally specious, if thats the reason, why bother testing anything other than dual core machines?

    Lets all ignore quad core computing until we can play games on them... is that the idea?

    This is the second poor quality review in the cases and cooling section within a few weeks, if Anandtech wants to be taken seriously, a serious re-think is required.
  • Acanthus - Monday, October 1, 2007 - link

    Many enthusiasts that are spending money on components for overclocking have opted for cheap quad cores.

    Sorry to sound frustrated, but this is getting rediculous when we are in the world of $270 quad cores.
