Today we are reviewing the Zalman CPNS7X LED, a CPU cooler with tower design, two heatsinks installed in a "V" configuration, three direct-touch heatpipes, and a 92 mm fan. Check it out.
Zalman's CNPS5X-SZ heatsink is an updated, vertical interpretation of a 2006-era heatsink Zalman released under the CNPS8000 nomenclature. Like its forefather, the CNPS5X-SZ fills the role of a lower profile, light weight cooler that's ideally suited to sub-95W TDP processors. It's stacked aluminum fins are connected by three 6mm diameter copper heatpipes to a small aluminum base block with a thin bit of copper covering the otherwise exposed heatpipes.
Lately at APH Networks, we have been suffering from the 'Australian effect'. By the 'Australian effect', I mean stuff always somehow turns out to be upside down. I have no idea how this has been happening in almost every review, but hopefully that bug does not hit this review as well, or else we might be in trouble. Either way, all I know is that there are some things that are better left right side up than upside down. Take your computer's CPU heatsink/fan, for example: Have you ever tried installing it the wrong way? How did that turn out... if you are not in Australia? I don't think it would be too appropriate to have the fins or the fan touching the CPU, haha. Anyways, where were we again? Oh right, it is now time to talk about today's product. By now, I'm sure most users want to know what we will be taking a look at today. The product in particular comes to us from Zalman, a renowned force in the computer cooling market with many budget to enthusiast products that may be used to suit any need -- where the CNPS5X SZ is a CPU heatsink/fan advertised to be "ultra quiet" with powerful cooling performance. Let us see how well it lives up to their claim, and how it stacks up in today's market.
The Zalman CNPS5X is a tower CPU cooler with three heatpipes and a 92 mm fan. Let's take a look at its performance.
If Zalman's new 5X cooler comes to market at the promised $30 pricepoint, this cooler is a very good value. It handled the Q6600 processor and its high thermal output with ease and even at 1400 RPM easily beat the OEM solution in near silence. With support for older Intel and AMD sockets, this cooler would make an excellent replacement for a borked OEM cooler or a good choice when added to a new CPU that doesn't come with a cooling device.
Want a bit of style, even though you have no extra room for the CPU cooler? Zalman may have your answer with the CNPS2X super low profile CPU cooler.
This little heatsink from Zalman is called the CNPS2X and it looks like it should be found on an entry level videocard, motherboard chipset or possibly a miniITX motherboard. It is small. To give an idea of how small, the impeller from a 120mm fan is larger than this entire heatsink.
Zalman enters with a new dual tower CPU cooler design with the single fan cooled CNPS14X Ultra Quiet cooler.
As a single fan heatsink the Zalman CNPS14X performs very well, but the higher the heat load the better the advantage there is to be gained from adding two more fans... so... Zalman include extra fan brackets for users who want to add their own 140mm fans.
Since this is a novel approach, Frostytech is going to test Zalman's CNPS14X heatsink in its single fan configuration (stock) and also in a three fan configuration.
The Be Quiet Dark Rock Pro 2 is a top-of-the-line CPU cooler. With the fans on high it's the best-performing cooler that we've ever tested, and with fans on low it's the most efficient. It makes it a great cooler for serious overclocking and for creating a silent PC, and even for a combination of both. The Zalman CNPS12X is also not a bad CPU cooler, and has its looks going for it. Performance-wise it's not on the level of the Be Quiet cooler, however.
