Review of the computer EvoPC Liquid Edition / Laptops and PCs

0 2,874

Our readers are already familiar with the company EvoPC specializing in the sale of rare components and computers with overclocked and modified components. Last time we tested a model from the Overclocking Series with two GeForce GTX 970 graphics cards and the scalped CPU Core i7-4790K (Devil’s Canyon), but today’s guest is perhaps even more interesting.


Closed liquid cooling systems CPU – has long been not exotic, but to remove heat from the graphics processor, water is still rarely used. In the latter case, they are either video cards equipped with their own “dropsy” in the regular delivery (such as AMD Radeon R9 295X2 or Radeon R9 Fury X), or modifications of standard models that the buyer performs under his own responsibility. Moreover, there are no ready-made sets of SVRs designed to cool the CPU and GPU in a single circuit. This is always piece work, and the price of components for a dropsy in this case is rather large – both because of the need for an additional water block for the GPU (and they are usually very sophisticated and expensive), and because of the high requirements for the thermal conductivity of the system , And this means – a powerful pump and a large radiator (radiators).

In general, completely transferring the computer to water (with the exception of the power supply, although it is possible) is the fate of enthusiasts ready for big expenses and hassle, not to mention the loss of the guarantee for the video card as a result of the dismantling of the regular air cooler and inevitable for NEO risk of leakage of coolant (however, with high-quality components the probability of an accident is low). In this, of course, there is half the fun, but if you still the result is more important than the process, then, fortunately, there are rare ready-made solutions – such as EvoPC Liquid Edition.

⇡ # Technical characteristics, the price is

EvoPC proposes to assemble almost any configuration under the brand name Liquid Edition, and as OWS, both ready-made systems with a closed loop and those selected from separate components are available for selection. It is the latter that interests us most. For testing, we were provided with a PC on the Intel LGA2011-v3 platform: a six-core Core i7-5930K processor is installed in the ASUS X99-S motherboard. The system is equipped with 32 GB of DDR4 memory. The video card is ASUS STRIX GTX 980.

The main components are well dispersed by the assembler. The maximum CPU frequency is increased to 4.3 GHz – at 600 MHz relative to the nominal. The video card, at the nominal frequencies of the GPU and the memory of 1178/7010 MHz, operates at 1374/8000 MHz. The “non-coherent” base frequency of the graphics core is chosen so that under the GPU Boost algorithm the algorithm raises it to exactly 1.5 GHz.

The operating memory operates at its nominal frequency of 2133 MHz.

The system has a solid-state drive with a SATA interface – Intel SSD 530 240 GB – and a hard drive Seagate Desktop HDD for 2 TB.

The price of this configuration is $ 3,500.

⇡ # External appearance

Like the EvoPC Overclocking Series tested last time, the Liquid Edition series systems are assembled in the Corsair Graphite 780T. It is spacious enough to accommodate a motherboard format up to E-ATX and XL-ATX. A white body is selected for this system.

Three 140-mm Thermaltake RIING fans provide air circulation in the interior: two on the front and one on the rear panel.

The buttons for enabling, resetting and controlling the case fans are located on the top panel of the enclosure. There are also two USB 2.0 ports and a USB 3.0 Type-A, connectors for audio headset.

Three more fans are hidden under the grill on the top panel, which blow air through the radiator of the water heaters. Both the front and upper grilles are fastened to the latches, opened and closed by pressing the corners.

In the dark, fan rings and LED strip fill the body with white light.

⇡ # The internal arrangement

The interior of the computer is matched in a single black-red-white color scheme, and even the coolant in the SVO is milky white. Each wire from the Corsair RM1000 power supply unit is plugged into an individual braid.

The liquid cooling system consists of EKWB components. The complete list is as follows:

  • water block for the central processor EK-Supremacy EVO;
  • water block for the video card EK-FC980 GTX Strix;
  • the back panel for the video card EK-FC980 GTX Strix Backplate;
  • three-section radiator EK-CoolStream RAD XTX (360): copper tubes and fins, brass chambers, capacity – 510 ml;
  • EK-DDC pump 3.2 PWM (capacity – 1000 l / h);
  • the cover of the pump EK-DDC X-TOP V2;
  • expansion tank EK-Multioption RES X2 with a capacity of 150 ml.

The circuit is constructed in such a way that the cooled water at the pump outlet receives a GPU water block first, often more loaded, and then the CPU water block.

Clock frequencies, acceleration, temperature

The thermal package of the Core i7-5930K and GeForce GTX 980 is 140 and 160 watts respectively at the nominal frequencies, but here it is still dispersed, so the cooling system is not an easy task. In order for the CPU to work stably at a frequency of 4.3 GHz, the supply voltage was increased to 1.264 V at a nominal value of about 1.1 V. The temperature in the OCCTP Linpack test is kept within 85 ° C. In principle, good water cooling makes it possible to move a little further both in frequency and in voltage, but the first attempts did not allow even 200 MHz to be added without raising the voltage, and when it increased the temperature approached 100 ° C. Also, let’s not forget that the GPU is cooled by the same circuit.

However, the task of cooling the video card successfully copes more successfully – even in FurMark the temperature of the GPU does not exceed 52 ° C, and the clock frequency keeps at around 1500 MHz. The GPU even has a small resource for additional overclocking in the range of about 50 MHz.

In real problems that load both components (games), the frequencies and temperatures of the CPU and GPU behaved in much the same way as in isolated stress tests. However, with the simultaneous loading in OCCTP and FurMark, the system still exhales: after 12 minutes of the test, the GPU still retained the frequency of 1.5 GHz at 59 ° C, but the CPU reached 104 ° C, and then began to skip cycles (which was noticeable On a sharp drop in temperature).

As a result, we stopped attempts to obtain higher frequencies from the computer than those obtained by EvoPC, and tested the performance in the regular mode for this PC.
