Reeven Justice RC-1204 – Test and Review

Since the web page was created back in 2010 I have already tested a few CPU coolers from the brand:

  1. Reeven Kelveros RC1202 Test and Review
  2. Reeven Arcziel RC-0903 Test and Review
  3. Reeven Arcziel 12 RC-1203 Test and Review
  4. Reeven Chrono Guard RC-0902 Test and Review
  5. Reeven Hans RC-1205 Test and Review

All of them showed very interesting design, some nice features and very good performance results. For that reason I am pretty eager to check what Reeven Justice RC-1204 can offer to me and all of the possible customers worldwide.

Reeven Justice RC-1204 arrived to me in a typical for the company very small and at the same painted in grey/yellow/black carton package with a big picture of the cooler together with some of the major technical details on the front side of the box. Of course, all of the other technical details were placed on the other sides of the package. A package which looks pretty nice but after all this article is for the content inside of it.


The first thing to notice after I opened the package was the 120mm Coldwing fan placed on top of a pretty big heatsink with very good looking copper heatpipes and of course a small yellow box holding the additional accessories. The installation manual was placed beneath the cooler.


After I took all products out of the carton package I believe it will be nice to start with checking what’s inside the yellow box holding the additional accessories and then proceed with the detailed cooler review. And this is what all of the additional accessories looks like when arranged for a picture.


The standard Reeven Justice RC-1204 package features:

  1. Completely painted in black metal backplate needed for both Intel and AMD sockets
  2. Silver metal square frontplate needed for both Intel and AMD sockets
  3. Silver metal bar made to hold the cooler attached to the front plate needed for both Intel and AMD sockets
  4. 4 plastic washers
  5. 4 rubber washers
  6. Metal screws needed so the mounting kit can be installed on Intel motherboards
  7. Metal screws needed so the mounting kit can be installed on AMD motherboards
  8. 8 plastic clips so two fans can be installed on the cooler
  9. A thermal compound
  10. A wrench to fasten the screws
  11. An installation manual

I can say that I am used to seeing more parts, but I guess these are all of the parts needed so this cooler can be installed both on Intel and AMD systems and I should add it is pretty nice to offer a combined mounting kit for both Intel and AMD platforms.

After I checked the additional accessories, I believe it is time to start speaking about the cooler itself.


Like every other modern cooler, Reeven Justice RC-1204 is made of three major components which I want to describe checking every detail one by one in this article. Of course, these components are the heatsink, the cooling fan and the mounting kit. So let’s get started with the heatsink.



Reeven Justice RC-1204’s heatsink is made of nickel plated copper contact surface, 6 x ø6mm copper heatpipes without nickel finish and direct contact with the processor as you can see from the pictures, and of course aluminum fins grouped together forming the cooling surface with overall dimensions of 161(H) x 70(D) x 125(W) mm and overall weight of  760 grams without the fan. Pretty serious dimensions, which I believe will show some nice cooling results. Anyway, I will talk about this a bit later. Now let’s check out all of the heatsink parts one by one…


As always, let’s get started with the contact plate.

Reeven Justice RC-1204 offers a perfectly milled flat, not very big and at the same time not very small contact surface made of copper with very shiny nickel coating to transfer the heat from the central processor unit through the 6 x ø6mm copper heat-pipes soldiered to the contact surface, U-shaped with some really serious bending angle and attached to the aluminum fins for dispersing the heat.

By saying bending angle I want to add that those pipes are bent so hard that they get a bit wider than the aluminum fin stack. At first I thought they might be in contact with some of the components near the socket but later everything was fine. And by saying fins, let’s pay some attention to the next part of the heatsink, which is actually the surface made for dispersing heat.

Reeven Justice RC-1204 offers a pretty tight and at the same time very thin fin stack structure with dimensions of 70(D) x 125(W) mm and on overall of 53 absolutely identical aluminum performance fins with very small fin gaps holding symetrically the copper heatpipes for transfering and dispersing the heat. Apart from that there is a 54th fin installed on top of the cooler which has only purpose – to boost the overall cooler appearance. The top fin is a bit smaller with the Reeven logo engraved in it and I should say it looks pretty nice.


Maybe you have already noticed but all of the fins are drilled symetrically on both sides. Those cuts are actually functional and made so the cooler can be fastened with a screwdriver.

Now let’s pay some attention to the cooling unit provided with the cooler so the heatsink can do its job.

Cooling fan:


Reeven Justice RC-1204 is equipped with one Reeven Coldwing 12 fan with dimmensions of 120 x 120 x 25mm working at revolutions per minute range of 500+/-250 ~ 1500+/-10% providing airflow level range of 27.61 ~ 82.13 CFM with noise level range of 4.3 ~ 29.8dBA. The fan itself is made of a square painted in black matte frame and a yellow propeller with eleven not very wide but very sharply angled blades. The fan is PWM powered and regulated by a pretty long sleeved in black mesh cable and connector.


Like every other cooler from the brand, this one is also made so the fan is attached to the heatsink with 4 yellow, plastic brackets as shown on the picture above, which are very tight and can be easily broken. The guys from Reeven added four additional brackets so a second fan can be installed or they can be used as spare parts if any of the brackets gets broken. And this is what the fan looks like when installed on the heatsink.


I can say that the cooler looks pretty nice but without a proper mounting kit it will be totally useless. So I believe it will be nice to check the combined Intel/AMD mounting kit…

Mounting kit:

According to the official technical details Reeven Justice RC-1204 is made to be installed using the same combined mounting kit on:

  1. Intel sockets: LGA775, LGA1155, LGA1156, LGA1366, LGA2011 and LGA1150
  2. AMD sockets: AM3, AM2+, AM2, AM3+, FM1, and FM2


And to install the cooler on my motherboard I will need these parts.

So let’s assemble and prepare the mounting kit for installing it on my motherboard:

The backplate with the bolts
The backplate with the plastic washers

The first thing to do was to prepare the backplate for installing on the motherboard. To do so I had to install the 4 long bolts through the AMD holes and add the rubber washers which will lie down behind the motherboard and later to add the plastic white washers which will lie down on the front side of the motherboard. So far so good. Let’s proceed with installing the mounting kit.

Next step was to add and fasten the front square metal plate needed for both Intel and AMD sockets.


And this is what the cooler looks like installed on the motherboard:

As you can see from the pictures above, the cooler provides enough clearance and can be used with even four DIMMs unfortunately without tall heatsinks. With the cooler installed I believe it is time to check out the testing rig and do the tests…

Test rig:

CPU: AMD Vishera FX-8350

  1. At standard frequency 4.020 MHz (at 1.344V)
  2. At low overclock frequency of 4.220 MHz  at 1.380V)
  3. At medium overclock frequency of 4.420 MHz (at 1.416V)
  4. At high overclock frequency of 4.720 GHz (at 1.452V)

Motherboard: GigaByte 990FXA-UD3

Video card: Sapphire 5830 Extreme 1GB DDR5 256bit

Memory: 2 x 4GB Geil Black Dragon 1866 MHz

Hard drive: Kingston SSD SV100S264G

Case: SilverStone Raven RV-03

Power supply: Antec HCP-750W

Cooler: Reeven Justice RC-1204

Thermal paste: Gelid GC-Supreme

Fan mounted:

For this test and review I am going to use the standard Coldwing 12 fan with dimmensions of 120 x 120 x 25mm working at revolutions per minute range of 500+/-250 ~ 1500+/-10% providing airflow level range of 27.61 ~ 82.13 CFM with noise level range of 4.3 ~ 29.8dBA.

The tests were conducted in a closed system with:

  1. 2 x SilverStone AP181 – 180mm fans on the bottom panel putting fresh air inside the case and spinning at about 1200 rpm
  2. 120mm fan on the top panel taking hot air out and spinning at about 1000 rpm.
  3. Room temperature of about 18 degrees.

Both of the SilverStone AP181 – 180mm fans were connected together to the chassis 1 connector and were rotating at maximum speed.

Testing procedure:

I will install Reeven Justice RC-1204 and do stress tests at standard frequency 4.020 GHz (at 1.344V), at low overclock frequency of 4.220 GHz (at 1.380V),  at medium overclock frequency of 4.420 GHz (at 1.416V), and at high overclock frequency of 4.720 GHz (at 1.452V) with just the standard fan installed on the cooler.

And this is what the CPU cooler looks like when installed inside the case and ready for testing..

Now let’s check out the test results:

Reeven Justice RC-1204 @ 4020 1.344V Reeven Justice RC-1204 @ 4220 1.380V
Reeven Justice @4020MHz 1.344V Reeven Justice @4220MHz 1.380V
Reeven Justice RC-1204 @ 4420 1.416V Reeven Justice RC-1204 @ 4720 1.452V
Reeven Justice @4420MHz 1.416V Reeven Justice @4720MHz 1.452V

All of the test results have been summed up in the following charts:

Results T

And the fan speed during the tests:

Results FS

I believe it is time to express my conclusions about the results, the vision and the structure of Reeven Justice RC-1204.

1. Reeven Justice RC-1204 performance:

Reeven Justice RC-1204 is one really modern CPU cooler offering very interesting structure featuring not very big and at the same time not very small perfectly milled contact plate, 6 very hard bended copper heatpipes combined with 53 aluminum fins with small distance gap and cooled by a very well balanced according to airflow/static pressure/noise fan made to provide the best possible cooling performance and compatibility for its size. As you can see from my test results, the cooler handled keeping FX-8350 at pretty decent temperatures with full load even at 4.7GHz which makes it a very good choice to be used with processors running at idle or full load at default or overclocked frequencies. I believe it will handle any scenarios.

Here I want to salute Reeven for the mounting kit, which is one really good idea to use the same brackets for Intel and AMD sockets for reducing the overall number of additional parts and make life easier for anyone who has decided to install the cooler.

2. Reeven Justice RC-1204 appearance:

Reeven Justice RC-1204 is a product featuring a pretty tight cooler design made to provide very good clearance around the CPU socket and the DIMM slots, combined with a pretty attractive silver/black/yellow colour scheme which could fit very well in every modern black or black/yellow case or modding project.

According to my review, I’ve decided that Reeven Justice RC-1204 deserves the following reward:

    Indeed the cooler showed some nice results.

    Long time ago I thought to make a catalogue for coolers too using the delta temps. But at one moment I abandoned the idea because…
    1. The coolers are with different dimensions, features and structure.
    2. When most of the people see the delta temps they will make their conclusions without paying attention to the details at point 1.
    Anyway at every article i give the ambient temp and if somebody want to do the math and then compare the coolers. I am not doing it cause it is not right to compare for example Reeven Justice with lets say Scythe Ashura or Noctua U14s

    Thank you for the comments and suggestions guys! The cooler is a good performer, indeed. Very good review as always!

    Great job, Dobri, just wanted to give a little suggestion for improvement. I like seeing the actual temperature the cpu has under load, however I think it would also be useful to give a perspective how the tested cooler compares to other coolers you have tested. It can be done easily if you take the ambient temperature and make a chart at the end with delta temperatures with a given fan scenario you choose. We do not need all the data in delta T, just 1 of your choise and the reviews will be even greater!
