Reeven Hans RC-1205 Introduction:

While it has been five years since OCC has reviewed a product from Reeven, we now have a couple of recent additions to the Reeven line up to look at. The Reeven RCCT-0901SP was reviewed here on OCC in February of 2009, and a lot has changed since then. And I admit I had not heard of Reeven until the Justice RC-1204 and the Hans RC-1205 showed up at my door. Reeven has a line of CPU coolers, fans, and a nice fan controller. There is even an Extreme Cooling Cup for "Professional Extreme Overclockers" and a warning that "This is not for everybody". Well, that is ok because being mere mortals, we are only focusing on the Hans RC-1205 CPU cooler.

From the Reeven website: "REEVEN is a newly established international manufacturer of PC related products. REEVEN's product lines includes the best quality of advanced CPU coolers, Cooling Fans, Power Supply Units, PC Cases and many other items. the target of our products will be a wide range of audience under our philosopohy 'Professional Quality Gears', for products that will withstand the highest demand."  So, I have the Justice RC-1204 and the Hans RC-1205 ready to be reviewed.  The Hans RC-1205 is somewhat smaller than the Justice RC-1204. This review is focused on the Hans RC-1205, while the Justice RC-1204 was covered separately.

Reeven Hans RC-1205 Closer Look:

The packaging for the Reeven Hans RC-1205 has a lot going on for such a small box. All sides of the box are full of information and graphics. The top of the box shows a nice view of the top of the cooler, showcasing the Reeven logo on the top logo plate, and lists the socket compatibility. The front of the box shows the cooler fan up front and has some useful dimensional information.












The bottom and back side of the package have technical information and specifications in six languages.



The sides of the packaging show a 360 degree view of the Reeven Hans RC-1205, so you know just what you are looking for once you open the box. Illustrations of the universal socket clips adorn the other side. Socket compatibility runs the gamut of pretty much every current in-production socket from AMD and Intel.



Opening the box, right away you are greeted by a sheet of foam to keep the cooler from bouncing around. Removing the foam, everything seems to be in good order. The base rests against a folded-in side flap, while the installation hardware is in a box below the cooler, and the fan is below the box of hardware.



The hardware consists of mounting components for AMD and Intel installations. The thermal paste is in a clear plastic pouch rather than a syringe-style dispensing tube. There are two metal fan clips to secure the fan to the fin stack.




The instruction sheet is well illustrated with a full parts list, and is laid out with easy-to-follow assembly and installation steps.


Reeven Hans RC-1205 Closer Look:

The RC-1205 is a large tower cooler that comes with one 120mm PWM fan. There are 50 aluminum fins capped off with a decorative top plate with the REEVEN logo stamped neatly in the center. The top plate also covers the termination points of the heat pipes. Some manufacturers leave the termination stubs visible, but Reeven keeps them covered up, and that makes for an aesthetically pleasing cooler. From any angle, the RC-1205 is a nice looking unit.

While this review is not really a comparison between the Justice RC-1204 and the Hans RC-1205, there is one thing to mention. The fan for the RC-1205 comes disassembled from the cooler, so you have to attach it yourself - this is not a problem, but for some reason the RC-1205 does not come with the plastic clips that attach the fan to the fin stack like the RC-1204 die. If you read the RC-1204 review, you will see how much I like those little yellow plastic clips.

This cooler, the RC-1205, comes with the more common metal clip, and normally I wouldn't think much of it. But I had a mildly difficult time getting these metal clips on there. Not a show-stopper by any means, and once you get the fan attached, it is usually on there for a long time; I just wonder why Reeven doesn't use the same plastic clip method for fan attachment on this cooler. It would require the RC-1205 fin stack to have the same notches for the plastic clips that the RC-1204 has, and perhaps the plastic clips were developed after the fin tooling for the RC-1205 was already done. Regardless, I really like those plastic clips used on the Justice RC-1204. Ok, enough about the clips - let's move on...












The side profile shows that there is plenty of room for a second fan if you want to do a push / pull configuration, but you will need to supply your own fan clips as the RC-1205 only comes with two for the included fan.



The four heat pipes stay within the confines of the fin stack.



The nickel-plated copper base is machined flat and ready for a nice application of thermal paste. Don't forget to peel off the plastic cover before you apply your thermal paste.



After removing the fan, you can see how symmetrical the fin stack is. There are 50 fins and the copper heat pipes are spaced to maximize the exposure to the air flow.



Along the bottom block are the four 6mm copper heat pipes. They are evenly spaced and fill the block. Then they twist and turn upward to meet the fin stack where they ultimately transfer the heat they pick up from your CPU to the fin stack. The mounting strap is loose, so it can be a little tricky to hold steady while the two screws are being installed. The top of the base is machined to accept the four tabs in the strap.



The Coldwing 12 PWM fan is rated at .42 amps and can move up to 82.13 CFM of air. The rated speed is 500 to 1500 RPMs with a noise level of 4.3~29.8dBA.



The rear mounting plate is robust and looks right at home on the back of the motherboard. The four studs have anti-rotate features so they won't spin later on during the installation. Looking at the top of the motherboard, there are the four plastic spacers, then the base mounting plate. This plate is secured with four nuts that are easily tightened with the supplied wrench. Pay attention to the orientation of the two threaded holes that hold the cooler to the base. This will affect which way the cooler (and fan) faces.



Regarding RAM clearance, the fan slightly overhangs the first RAM slot on my MSI Z87-GD65. Tall RAM modules may cause you some problems on that first slot. You could relocate the fan to the other side of the fin stack and open the space for the first slot. Otherwise, the Hans RC-1205 is a nice addition to show off in your case.

Reeven Hans RC-1205 Testing:

Testing of the Reeven Hans RC-1205 will be accomplished by installing the cooler into the test system case, rather than a test bench. Most systems are built and mounted into a (relatively) sealed chassis, so this method will be used to generate the idle and load results to give a real world view as to the cooling performance one can expect, based on the test system listed below. Of course, your results may vary by several degrees due to case design, case fan placement, and ambient air temperature. The CPU load is generated by Prime 95 version 27.9 for a period of two hours, with a cooldown period of one hour after the computer has returned to an idle state. Real Temp 3.70 is used to log the temperatures with the highest and lowest averages across the four cores of the Core i7 4770K test CPU. Ambient temperatures are kept at 24 °C during the testing to minimize the effect of temperature variations. Each cooler is tested with the manufacturer-supplied thermal compound as delivered.


Testing Setup:


Comparison Coolers:











At idle, the Reeven Hans RC-1205 has no problems keeping the 4770K CPU at 26 °C stock with the included fan, which is of course no surprise. With the CPU loaded, the temp pops up to 74 °C, which is a little warm, but certainly not dangerous.

As for overclocking, we are at 32 °C at idle, which is just fine, and close to 9 degrees warmer than stock at 83 °C under load, which is excellent. I was expecting it to be a little warmer, but the heat is held to 83 °C. Just for giggles, I added a second fan from the Reeven RC-1204 that I am also reviewing and I was only able to knock the OC load temperature down by just under two degrees. Temps are fine with one fan, so I won't complain. The Reeven Hans RC-1205 can keep you cool whether your system is a daily driver or geared up for a mild overclock.

Reeven Hans RC-1205 Conclusion:

My experience with Reeven certainly leaves me with a positive feeling. I was not familiar with Reeven products, but the Hans RC-1205 gets the job done and looks great while doing it. So what do I like about it? To start, I like the size. It is not so massive that it smothers you motherboard, but it is large enough to handle the heat of a mild overclock. And when you turn up the heat, the fan is almost dead silent.

Installation of the Hans RC-1205 is fairly easy. The mounting strap that holds the cooler to the base is loose; meaning it is not attached to the base like you find with many of the Noctua coolers. If you can lay your case / motherboard flat, then you won't really have any problems mounting the cooler to the base, but I do my cooler installs in my test system with the case upright, and gravity is not my friend. One thing I didn't like are the metal fan clips. I had to fool with them a bit to get them in position. Now, this is something you typically do once, and that is it, so it was more of a mild inconvenience and isn't worth listing as a con.

The Hans RC-1205 is a bit thinner than the Justice RC-1204, and it does not overhang the RAM slots as much as the RC-1204, but there is a little overhang on that first RAM slot. If your RAM is not topped off with tall heat spreaders, you will likely be able to populate all the DIMM slots. RAM with tall heat spreaders may prove to be a problem on the first slot, so you will want to verify your RAM compatibility ahead of time.

And finally, let's talk about performance. The Hans RC-1205 can handle the thermal load of normal daily use and stock performance is just fine. Overclock and crank up the load, and the Reeven Hans RC-1205 can meet the demands of heat removal. Reeven gives you great build quality to go along with the attractive styling. Pricing is yet to be released.

If you're thinking about an air cooling solution that looks good and can handle the heat, then you can't go wrong with the Reeven Hans RC-1205.
