Raijintek Atlantis Review
Raijintek Atlantis Review
Raijintek has released another watercooling kit named Raijintek Atlantis Series. All parts can be ordered separately and put together in DIY style. Today we are going to have a look at each component and tests them together in one of our systems. The set consist of following parts:
-CWB-C1 cpu block
-RAIAQUA-T1 liquid coolant
-RAI-R20 reservoir (shorter version RAI-R10)
-VRM (MOS) water block
-GWB-C1 GPU water block
As you may have already noticed, the radiator is missing as there is no solution yet from Raijintek’s site. So, you may keep in mind, that you’ll need also additional fittings and some radiator to make this system work properly. In our test, we are going to use only one 120mm copper radiator from Alphacool ST30 together with well known Noctua NF-F12 fan. So the test results will be indicative only, and we are not going to compare them with any previous test results. Before we start, let’s have a closer look at each part of this set, starting with CPU block. The massive CPU block is made of full copper with nickel plating. For effective heat transfer between CPU and water block, the contact area on water block is mirror polished. Thus, the micro air spaces between two surfaces can’t block the heat dissipation. The threads are G1/4″ which is standard in most liquid cooled PC systems, and so, you won’t have any compatibility issues there. The block is compatible to all current Sockets: LGA 775/115x/1366/201x CPU (Core™ i3 / i5 / i7 CPU) as well as FM2+/FM2/ FM1/AM3+/ AM3/AM2+/AM2.
The micro-fin structure inside the water block will maximize the performance. There’s only about 0.15mm space between fins just enough for water to pass through. This fin density also creates high flow resistance in the loop, but for the included pump, it’s no problem at all. The pump works with max. 10.8W at full RPM with flow rate of 450L/H. We used the lowest RPM settings as with the higher RPM also the noise will be noticeable. We recommend to use any foam or rubber under the pump to prevent vibrations being transferred to whole case.
As the pump has to be always fed directly from reservoir, this is connected with the pump on top. The system will only work in vertical position and can’t be installed in horizontal position in any way. The coolant is clear and Raijintek has included 3 main color dyes. Red, Green and Blue. With this option you are able to mix plenty of color combinations,and so easily match your system color theme.
The CPU block installation was a breeze. Simply fix the backplate with special standoff nuts and then mount the CPU block. Don’t forget to apply the included thermal paste. Any fittings using G1/4″ thread should fit the CPU block.
We are using Bitspower compression fittings for 13/10mm (OD/ID) tubing.
The whole system is actually not complicated at all, and can be installed by any beginner without previous experience.
The coolant is mixture of distilled water and propylene glycol, which will protect the loop against algae growth. It also helps against corrosion. The included 500ml bottle of coolant would most likely not be enough for one loop, depending on tubing length and radiator size. You may keep that in mind during purchase and you better order two bottles. The mixture is ready to use, no need to add additional distilled water. We recommend not to add any additional liquids nor mix it with other coolants. The non-toxic, and substance free PVC tubing is not clear and has bit of a of foggy shade. It’s not very prone to kink which is good, but you may keep an eye on your system after first couple of hours as the coolant gets warm and the tubing gets softer. It’s approx. 2m long.
The GPU block is made of full copper material which was melted by alloying brazing. GWB-C1 is compatible with nVIDIA & AMD GPUs. It offers easy installation. Also for user who wish to cool their motherboard VRM (MOS), Raijintek offers this small water block made of full copper and anti-corrosive nickel plating.
All testing was done on test Bench-table with a room ambient temperature of 22- 23°C and if temperature changes we will add delta T °C to the results.
Before testing we run 10 minutes of Prime95 followed by 30 minutes of idling. This warm up period was done at stock CPU core frequency. For noise testing we are using fanless PSU. We mostly do fan noise test over night so we have our room as silent as possible.
We take noise values from distance of 30cm.
Testing System 1 :
Software: OCCT 4.4.1, Easy Tune
For testing we are using OCCT software and between each test we leave the system at least 15 minutes to rest. Thus, the temperature comes back to the IDLE state. Followed by overclocking with help of Easy Tune Software (for Gigabyte mainboard) or for ASUS mainboard (CPU Ratio only). Each test lasted for 15 minutes. If the temperature of any CPU core exceeded 85°C the test was automatically turned off and the value of the results we have marked as “failed”. The resulting temperature in the tables are the average temperature of all cores. The results of the tests are influenced by many factors such as: the amount of thermal paste, pressure between the processor and CPU block, humidity, thermal conductivity of thermal paste, etc.. Therefore this results should be considered as indicative only.
Intel® Core™ i5-4690K Processor
We have measured the pump noise from distance of 30cm of 39dB(A) at lowest 3500RPM.
Raijintek Atlantis Series set is offering good cooling performance, but the pump will make itself known inside the system. Even with lowest Voltage it runs at 3500RPM and it’s pretty loud as it produces a lot of vibrations. On the other side, the water flow rate was still pretty high to push the coolant through micro-fin structure inside the CPU block. Adding GPU block and bigger radiator into the loop would not cause any issues with performance.
The build quality of CPU block and reservoir is at decent level. The pump has its PWM controller attached with the additional cable. It doesn’t look very professional, but it works without any issues, and it’s easy accessible, should the pump be mounted in some space restrictive cases.
The reservoir comes in four color options and two sizes at the moment. The longer with 200mm and the short one with 100mm in length. Diameter of both is ø64mm. The anodized aluminium parts of the reservoir come with black, blue, red and gold color. As the coolant flows into reservoir through inlet on top, it makes a bit of a noise together with air bubbles, but this will disappear after 1 hour of use when the coolant and air in the loop stabilize. The noise will appear again when the system is switched off for a while. There is no additional reservoir holder and the whole weight is held by the fitting between the pump and reservoir. We recommend to be careful during reservoir/pump installation inside your system, so you don’t break the plastic thread on the pump top.
When it comes to GPU water block. We can not speak about high build quality and the block won’t win any design contest for sure. The only positive properties are its mirror polished contact surface and the flexibility of usage for more graphics cards.
