be quiet! Shadow Rock LP Features:

  • High compact cooling capacity of 130W TDP
  • Four high-performance 6mm heat pipes carry heat to the optimal locations on the cooling fins
  • A silence-optimized Pure Wings 2 120mm PWM fan supports the best balance of cooling performance and quiet operation
  • Nine silence-optimized fan blades with high airflow capabilities reduce noise-generating turbulences
  • Durable rifle-bearing technology contributes to a long lifespan of up to 80,000 hours
  • Even at 100% full fan speed, overall noise is a scant 25.5dB(A)
  • Low-profile design saves space and allows easy access to components even within the tight confines of compact PC enclosures
  • Design supports mounting from atop the mainboard, greatly increasing convenience
  • Compatibility with all current Intel® and AMD™ sockets
  • Attractive design thanks to aluminum top cover and heat pipe caps
  • 3-years manufacturer’s warranty

be quiet! Shadow Rock LP Testing:

Testing involved recording temperatures for the CPU during idle and load phases. The load was simulated by running Prime95’s small FFTs for one hour. The maximum temperatures were recorded using HW Monitor 1.21.0. Please note that each cooler is tested from its factory setup, including location of fans, unless otherwise noted. We start out by loading the CPU at stock speeds (3900 MHz) and then overclocking to 4200 MHz.


Testing Setup:



Typically I test a cooler in two states, one being with the CPU running at stock speeds, and the other being with a mild overclock. The intention is, of course, to see how the cooler performs under two different thermal loads. So, being a small cooler, I would expect to see some higher temps than with a larger cooler. And that is indeed what we saw, but unfortunately the high temps occurred during the stock CPU speeds. I removed the cooler and checked to make sure the thermal paste was adequate and still in place, and it was, and I checked the mounting to verify that the cooler was properly mounted. Everything looked good, so I tested again and got the same results. With a temp of 96 °C coming in at stock speeds (under a load), there was no point in pushing it with an overclock.

Now, in defense of the Shadow Rock LP, let me say that the 4770K puts out a lot of heat - especially when you move into the overclocking zone. And the intended application for this cooler is not in a gaming rig that gets pushed hard. It is not really for an overclocked CPU. Be quiet! has many capable coolers that are designed for just those purposes. I want to stress that this cooler is designed for a small form factor or HTPC case where space is limited. And those type of systems are not usually pushed to the thermal limits.

I want to show a little color here with the FLIR camera. This shows the heat intensity, with shades of blue being the relatively cool background, and the purple and red are where things are getting warm. Yellow is the warmest, and with no fan attached, you get the best thermal image, but it doesn't take long for the heat to build up. After running for just a couple of minutes, the surface temp of the fin stack is pushing 40 °C. You can easily see each heat pipe as it passes through the fin stack. The heat, in general, is fairly well distributed throughout the cooler. 


Here are a couple shots of the cooler without the fan attached. The cooler actually has two fin stacks - the large one on top that has 54 fins, and a smaller one tucked under that has 34 fins. The top fin stack receives heat from all four heat pipes, and the lower fin stack receives heat from two heat pipes. Keep in mind that the fin stacks are not very thick and this is a necessary evil, since the point of the design is to fit in small, shallow cases. This cooler comes with the thermal paste pre-applied, which is rather convenient. I smudged it a little on the left side, but that won't hurt anything.



The Pure Wings 2 120mm PWM fan provides the airflow through the fin stack. The fan spins up to a maximum of 1500 RPMs and generates only 25.5dB(A) at full speed. One nice advantage of the top flow cooler is that the air is pushed down across the motherboard, which aids in cooling some of the motherboard components. Typically the RAM, VRM, and sometimes the chipset(s) see the most airflow, but even the graphics card can benefit from the additional airflow.
