Raijintek Themis EVO Review
Category : Aircooling
Published by Marc Büchel on 03.03.14
With the Themis EVO, Raijintek is bringen an updated version of their Themis cooler to the market. Compared to the predecessor there is one more eight millimeter heatpipes as well as an addtional fin. Other than that the heatsink has grown quite a bit bigger and we're rather surprised if this aggressively price cooler is going to convice.

If we had to define the type of cooler the Themis EVO is, then we would say it is a single tower cooler. This type of cooler comes with the advantage that manufacturers can realise a huge cooling area. The disadvantage over down-draft coolers is that no air is directed towards the motherboard directly, therefore none of the onboard components receive direct cooling. Raijintek makes their Themis EVO from aluminium and copper. Wehen it comes to the heatpipes, they establish direct contact with the CPU. Other than that there is a total of four heatpipes, which each have a diameter of eight millimeter. Furthermore the 54 fins have been soldered to the heatpipes.

We could not find any manufacturing mistakes on our sample, and the Themis EVO has been well made, which means that manufacturing quality is on an reasonably good level. Since Raijintek really optimized this cooler towards an aggressive price point, the fins are very thin and if you strike over them you hear a slight rattling noise. The heatpipes are parallel to one another, which make the air travel evenly through the fins. Furthermore this cooler comes with a total of 54 fins, which have been connected to one another for additional stiffens.

The Themis EVO ships well protected, that none of the parts included will be damaged during transportation. Raijintek includes not only an Intel but also an AMD mounting kit. Therefore the cooler is compatible with both worlds right out of the box. Raijintek also equips this cooler with one of their own fans. The fan in the delivery which measures 120 x 120 x 25 millimeter.

Installation of the Raijintek Themis EVO is quite easy, as it should be. The thermal compound is not pre-applied and comes in a small bag. The overall pressure on the CPU is quite good and you get one universal backplate, suitable for AMD and Intel sockets.
The Raijintek Themis EVO is rather big and there might be compatibility issues with memory modules such as Kingston HyperX or Corsair Dominator. Apart from that installing the fan is easy and the rubber grommets keep vibration to a minimum. Raijintek threw in an additional set of rubbers in case you decide to use it in a push-pull configuration with two fans.

To measure cooling capacity we took temperatures in idle and load with the fans at 7 and 12 V. The idle temperature represents the lowest temperature hit by the processor package after 10 minutes in idle. The load temperature is the highest temperature hit by the processor package after one pass of wPrime v2.10. The wPrime test takes 4 minutes and puts load on all 8 threads. Room temperature is 25°C.

At this point we plugged the fan(s) to the motherboard CPU fan header and let the motherboard take care of fan speeds. In other words the motherboard will adjust the fan speed via PWM signal according to CPU temperature. The idle temperature is the lowest temperature hit by the processor package after 10 minutes idle. The load temperature is the highest temperature hit by the processor package after one pass of wPrime v2.10. The wPrime test takes 4 minutes puts load on all 8 threads. Room temperature is 25°C.

Conclusion
| General | + | - | |
| The Raijintek Themis EVO is yet another cooler from Raijintek that offers great bang for the buck. Cooling performance is good, noise level is ok, manufacturing quality is also good and as we already mentioned the price is highly competitive. Unfortunately there is a distinct noise coming from the bundled fan's bearing, which is well audible when the fan blades are rotating a low rpm. Therefore we would love to see a fan that is of higher quality. |

| Installation | + | - | |
| Mounting is quite easy and practical , the Raijintek anti-vibration rubber fan mounts do their job well and fans are also easy to mount. If you wish there are enough fan mounts to realize a push-pull configuration. The mounting mechanism is solid and the thermal compound, that comes in a small plastic bag, does is job reasonably well. |
- Easy and practical
- Compatible withj all Intel and AMD Sockets |
||
| Performance | + | - | |
| The cooling performance of the Rainjintek Themis EVO is definitely good. It does a way better job than most, if not all, cheaper coolers and to make things worse, for competition at least, it even does a better job than some more expensive and even high-end coolers. | - Cooling performances | ||
| Noise Levels | + | - | |
| Overall noise level, that is something Raijintek could work on if there is going to be a next revision of this cooler. When the bundled fan is running at low rpm there is a distinct bearing noise, that is rather well audible. At full blast, noise levels are ok compared to the competition, but for people who demand a silent cooler 40.1 dBA is too much. | - Bearing Noise | ||
| Recommendation / Price | + | - | |
| Should you be looking for a cooler with excellent price/performance ration, then the Themis EVO from Raijintek is a safe bet. Overall you should also consider that this 33 Euro cooler is not the most silent model we've ever had for testing. |
