Cooling the Processors

I want his build to be quiet(!), but I didn’t want to compromise on performance either. And as we all know, there is pretty much only one country you can go to if you want efficiency: Germany.
Even though this Germany based company has quite a reputation, I have never owned a product from be quiet! but always wanted to.

And without further ado, I give you the Shadow Rock Slim:

The box it comes in is sturdy, and keeps the Shadow Rock Slim safe during transportation. On the front it reads that the SRS is rated to cool a CPU to up to 160W TDP. My Xeon e5-2630L is rated to 60W TDP, so the SRS should be more that capable of cooling my processors.

A short “about” of be quiet!, the highlights of the SRS and raw data is dominating the back of the box.
The box is held almost entirely in black. Only accentuated by orange and silver.

On the side of the box be quiet! Tells us a little something about the application in both English and German.

And on the bottom we can see that it is not only yours truly that is excited about the Shadow Rock Slim; numerous awards are righteously advertised.

The first thing that greeted me, as I opened the box, was the quick installation guide. You will want to keep that near when you are installing the SRS to the motherboard later, at least to help you identify the parts you will need for your particular motherboard, or rather your particular socket.

Digging further into the box reveals the top of the Shadow Rock Slim, and what a sight it is, beautiful brushed aluminum, and caps the hides the hideous ends of the heat pipes.

Behind the heatsink is a yet another box, which contains the bits and pieces that are necessary to mount the SRS to the motherboard.

There are ridges on the blades, this should enhance airflow, and minimize unwanted noisesrs-fan-blades

On the back of the fan we can see the specifications. A thing that I am particularly excited about is that it is a PWM fan, that means that the RPM is more or less under my control. Given that the motherboard has PWM headers for the fans. PWM headers have 4 pins, instead of the usual 3 pins. The PWM connector on the fan is still compatible with the ordinary 3 pin header, it just means that it will run at a constant 1400 RPM.

Am I the only one that gets a little high when watching those evenly spaced fines in that heatsink? The fan is with its 135mm oversized comparing to the heatsink. This gives me the possibility to adjust the height, should the fan interfere with my RAM modules, I suspect no problems in that area though.

The ends on the heatpipes  are seldom a thing af beauty, those caps be quiet has mounted to hide them are a really good idea, and boy! that top of the heatsink; I like it, I like it, I like it.

I really am crazy about the overall color scheme of the Shadow Rock Slim, it matches the be quiet! theme; The black fins of the fan, the silver fins of the heatsink and the orange of the cobber heatpipes.

From this angle you can see the rubber grommet that isolates the fan from the heatsink minimizing vibrations.

From the side you can see how the fan clips snugly fit between the fins and snap in place.


Again with the evenly spaced fins, I just can’t get enough.


With two of these in my build I’m confident that it will run both cool and quiet. As mentioned before, the SRS is rated for CPU’s up to 160w, that gives me a staggering 100w clearance, so in theory it should be possible to have the fans spin at a really low RPM.


My only concern with the SRS is the finnish of the contact surface, it has not the mirror finnish that I had hoped for, but it is for me a minor thing, as i’m sure that the SRS will perfom as it should in spite of this, besides it can be smoothed out fairly easy with some fine grid sandpaper. – Which could be interesting to see if that has an impact *hint-hint*
