Inter-Tech Company offers the Dynatron L-5 II water-cooled cooling system with a closed loop, equipped with a 120-mm heat exchanger. It is designed to provide both high cooling performance and installation flexibility. The price / performance ratio also seems to be attractive. It will be interesting to look at the results of the Inter-Tech Dynatron L-5 II tests.
Inter-Tech company offers components for PC since 1996 – not only for OEM segment, but also for ordinary consumers. In addition to housings and power supplies, Inter-Tech also produces cooling solutions. As a rule, in the assortment there are only air coolers. But Inter-Tech did not ignore the modern fashion on the NWO with a closed loop. Both models Dynatron L-5 and Inter-Tech Dynatron L-5 II are equipped with a 120-mm heat exchanger.
The difference between the two models is that the Inter-Tech Dynatron L-5 II fan is equipped with a backlight. In other respects, both systems are identical. It’s nice that the price is less than 50 euros.
Before we proceed to the tests, let me quote the specifications of Inter-Tech Dynatron L-5 II:
In addition to the mounting accessories and manuals, the Inter-Tech Dynatron L-5 II includes a small syringe with Antec thermal grease and a frame for attaching the radiator. This frame can be installed between the heat exchanger and the housing. But you can screw the radiator and directly to the PC case.
Most SVO with a closed loop use a pump on a water block, but the design of the Inter-Tech Dynatron L-5 II is somewhat different. The pump is integrated in the heat exchanger. As a result, the water block turned out to be compact and flat.
But the heat exchanger is larger than usual. The width is the usual 12 cm, but the length has increased to 16.5 cm. The reason lies in the integrated pump, which is just added to the side. Therefore, buyers should pay special attention to the compatibility of the radiator in comparison with other “all in one” solutions. A heat exchanger, a pump and a fan form a visually integral device. However, the angular shape and the gaps between the components can not go anywhere.
On the radiator there are standard openings for a 120-mm fan. Therefore, there is nothing to prevent the heat exchanger from being screwed directly to the PC case.
Inter-Tech somewhat complicated the task for those users who like to experiment. The complete fan is screwed not with standard cross screws, but with small hexagonal screws. Interestingly, the round frame of the fan is inscribed in the corresponding recess of the pump body. Therefore, it will be very problematic to install a different fan model. Unfortunately, we could not find the appropriate key for a tiny hexagonal screw head. Therefore I had to do without tests with a reference fan.
From the radiator with a pump leave two cables in a braid. To power the pump, a cable with a 3-pin plug is designed, and the fan is connected by a 4-pin plug with PWM control.
The water block looks relatively modest. From above you can see only a black plastic casing, from which two 30-cm tubes come out. A round protrusion on the center allows you to apply a mounting plate for AMD or Intel processors.
The base of the water block is made of copper to improve heat transfer.
Install the Inter-Tech Dynatron L-5 II water block very easily, the mounting plate is screwed directly to the back plate through the holes of the socket. The manufacturer offers a set of different screws with springs for different sockets (one set for AMD, one for Intel LGA 2011, one for Intel LGA 775 / 115x / 1366). But the rear plate is not fixed, so the second pair of hands when installing the water block will not hurt.
Due to the length of the tubes, the heatsink in large cases can only be installed on the back panel or under the cover. At our test NZXT H630 we installed the heat exchanger under the cover without problems. No problems arose, the waterblock did not conflict with the components around the CPU socket.
Unlike an air cooler, in a typical water cooling system, the source of noise is not only the fans, but also the pump. And for a few models the pump works really quietly. Such successful models include, for example, SVO be quiet! Silent Loop. In our test lab, the Silent Loop 240mm system was quieter than the Inter-Tech Dynatron L-5 II, despite doubling the number of fans. Subjective feelings confirm instrumental measurements. At 1.000 rpm, the 120 mm fan noise and hum were audible. However, after the game is launched, the fans of the video card come to the fore. But if you need a quiet solution, then it hardly makes sense to take an Inter-Tech cooler. And it is not possible to significantly reduce fan noise.
At maximum speed, the noise level of the Inter-Tech Dynatron L-5 II starts to irritate. In our tests, the new cooler bypassed even the combination of Le Grand Macho with the extreme fan TY 143. Of course, it will be interesting to look at the cooling results, but this speed for everyday work is not suitable.
In the next test scenario, we will evaluate the performance of a cooler with a standard fan at 1.000 rpm and at maximum speed. For the tests, we performed measurements without the housing cover, so that it does not limit the cooling performance.
As with the noise level, the Inter-Tech Dynatron L-5 II performance evaluation was twofold. When the fan runs at maximum speed and makes noise like a vacuum cleaner, we get a decent cooling performance. SVO shows the result on a par with the best air coolers, second only to other SVO with a larger 240-mm heat exchanger. But, as can be seen from our noise level tests, it is unlikely that a user will survive such a mode of operation for a long time. With a speed of about 1.000 rpm, when the noise level can be called tolerable, the 120 mm SED gives up its positions and shows performance at the level of conventional tower coolers.
As we already noted above, because of the problems of installation, we were unable to perform tests with reference fans.
Several years ago, water cooling systems remained niche products that few companies offered. Today in the market we get a very wide range of models, and technology has made significant progress. As for everyday operation at home, it is important not only the performance, but also the noise level. For the same models Alphacool Eisbaer and be quiet! Silent Loop it is well noticeable that SVO can work barely audible.
Unfortunately, until Inter-Tech Dynatron L-5 II progress has not reached. And a fan with PWM control, and the pump can be heard at any time. Not pleasing and additional difficulties associated with the replacement of the fan. However, while the fan is running at low speed, its noise level remains within reasonable limits, and the cooling performance is still sufficient. If the user needs a higher cooling capacity, then the stock is available. But at full speed fan Inter-Tech Dynatron L-5 II starts to make noise, like a vacuum cleaner. The performance of the NWS complies with the best air coolers. But the price is pleasantly low.
In general, the price is cheaper than 50 euros is the main advantage of the Inter-Tech Dynatron L-5 II. The above-mentioned competitors in the SRO segment cost 30 euros more. Yes, and many air coolers with two tower radiators, too. The advantages of Inter-Tech Dynatron L-5 II include the low height of the water block compared to air coolers. Therefore, the SVO is perfect for systems of small form factor, where it is required to bring heat outside the confined space. At the same time, the pump here is slightly larger than comparable CBOs with a closed circuit.
Inter-Tech Dynatron L-5 II does not impress with appearance or quiet work. But if the noise level is not critical for you, you will get an SVR with a sufficient reserve of performance at an attractive price.
