[Material evaluation] Be quiet

In the field of consumer grade high-performance radiators, the upper limit of integrated water cooling radiators is really high. Even the BIOS of some mainboards unlocks the power wall by selecting the push down, tower and integrated water cooling radiators. However, this does not mean that the performance of air-cooled radiators is not satisfactory, especially the high-end twin tower heat pipe air-cooled radiators, which can even break the wrist with mainstream water cooling, such as the DRAK ROCK series air-cooled radiators launched by be quiet.

Be quiet! DARK ROCK series air-cooled radiators feature high performance and silence, including DARK ROCK ELITE and DARK ROCK PRO 5. They are compatible with Intel and AMD full platforms, including Intel 1700, 115x, 1200, and AMD AM4 and AM5. DARK ROCK ELITE is the most high-end model of the DARK ROCK series air-cooled radiator. It supports up to 280W TDP CPUs and mainstream RGB light effects; The DARK ROCK PRO 5 is not equipped with RGB light efficiency. It supports up to 270W TDP CPU, so the cost performance ratio is better.

one Pure black temperament super gas field

The two radiators, DARK ROCK ELITE and DARK ROCK PRO 5, have a lot in common. The accessory kits are identical, including the fixed backplane, fixed fasteners and screw columns of the Intel/AMD platform, and delivered with gray thermal conductive silicone grease. In addition, there is a long rod cross screwdriver with be quiet on the top! The brand logo of.

The main body of the DARK ROCK ELITE and DARK ROCK PRO 5 radiators are basically the same in specifications. They adopt a double tower design. The cooling fans and fins are designed separately. The all black color matching is very suitable for matching with black chassis. The surface of dense and thick aluminum fins is coated with black ceramic particles, and runs through seven black high-efficiency pure copper heat pipes, which are fixed by reflow welding technology. The heat on the CPU surface can be quickly transferred to the fins for radiation, and then blown away by the cooling fan. Between the two towers is a built-in fan mounting position. It should be noted that the height of these two radiators reaches 168mm, which requires a certain depth of the chassis.

The size of the front fan of DARK ROCK ELITE is 135mm, and there is a be quiet on the blade! Exclusive designed mute pattern, matched with a unique shape of the outer frame and fixed with screws and heat sink, below is the memory installation position. In order to adapt to different heights of memory, the fixed bracket at the rear of the fan is equipped with a section slide system that can be moved up and down, which can be adjusted by the user. At the same time, the fin notch height of the radiator is relatively high, improving the compatibility with memory.

It is clear at a glance by referring to the official figure below.

The size of the front fan of the DARK ROCK PRO 5 is 120mm, which will not interfere with the memory below during installation. Both sides of the fan are fixed with elastic steel wires and cooling fins. In addition, as can be seen from the picture, the motor of the front fan is very "sturdy" and adopts a 9-blade design, with be quiet on the blade! Silent lines ensure air volume.

The built-in fans of the DARK ROCK ELITE and the DARK ROCK PRO 5 are of the draw out design, and the top is equipped with an integrated cover plate, which can cover both ends of the heat pipe while giving the radiator a strong sense of integrity. However, the design style of the top cover of the two is different. The center of the DARK ROCK ELITE cover plate is a large-area rectangular metal plate with rounded corners, which uses drawing technology and full black tone, and is lined with metal be quiet! The logo of our product is surrounded by a light ring made of translucent light guide material, which is surrounded by a black metal mesh. The metal mesh on the top cover of the DARK ROCK PRO 5 is designed on the left and right sides, and the octagonal part in the middle also has a metal be quiet! The product logo of.

The effect of the RGB light ring of the DARK ROCK ELITE radiator supports the light effect linkage with multiple mainboards. Although the overall visual experience is not as fancy as that of the liquid cooled radiator, it has a sense of finishing, making the atmosphere of the chassis in one step.

Seen from the side, the embedded fan and the upper cover plate are T-shaped and bear the product logo of DARK ROCK PRO 5/DARK ROCK ELITE.

From the label, the embedded fan models of these two radiators are respectively DARK ROCK ELITE/DARK ROCK PRO 5, which has the same name as the radiator, but the actual models are Silent Wings, which uses a 6-stage fan motor and fluid dynamic bearings, with a maximum speed of 2000 rpm and supports PWM speed regulation of the main board. The fan diameter is 135mm, the number of blades is 7, and the surface is equipped with be quiet! The mute pattern of technology.

This is the appearance of two radiators with built-in fans, highlighting a very powerful gas field.

It is worth mentioning that the outermost ring of the upper cover plate of the two radiators can be removed, which can be seen from the magnetic suction design. In fact, this upper cover plate is actually the fan speed control center. There is a two gear toggle switch under the outermost ring. The P gear is the performance performance, and the Q gear is the Quiet mute. Users can switch according to actual needs.

The bottom of the radiator is a pure copper contact block with nickel plating process, and 7 heat pipes run through it. The contact surface is provided with CNC fine thread relief teeth, which can increase the heating area and improve the heat exchange efficiency. However, there is no preset thermal conductive silicone grease. Users need to apply it by themselves. Remember to tear off the protective film on the surface first. In addition, the fixing screws of the radiator are fixed together with the bracket, without fear of falling off or losing. The unique frame fastener can ensure that the bottom of the radiator fits closely with the CPU surface.

two Heat dissipation test pressure 5.7 and 5.6GHz

The DARK ROCK ELITE and DARK ROCK PRO 5 radiators support up to 280W and 270W TDP CPUs, so the ideal product is the Core i7-14700K. Although only the Core i5-14600K is used in this test, the upper limit of these two air-cooled radiators can still be tested by overclocking. The Core i5-14600K continues the Intel 7 process, has 6 performance cores and 8 performance cores, a total of 14 cores and 20 threads, the performance core frequency can reach 5.3GHz, and the design TDP is 125W.

After actual overclocking, the full core frequency of DARK ROCK ELITE's performance core is stable at 5.7GHz, the performance core is 4.3GHz, and the maximum power consumption is about 228W.

When using the DARK ROCK PRO 5, the full core frequency of the CPU performance core is stable at 5.6GHz, the performance core is 4.3GHz, and the maximum power consumption is about 212W.

Next run AIDA64 System stability test. The test item is Stress FPU, which is commonly known as single baking. After 20 minutes of baking, when using the DARK ROCK ELITE, the full load temperature of the CPU is basically constant at 97 ℃. Although the temperature is a little high, this is to cope with the Rui frequency performance of the Core i9, and the CPU does not reduce the frequency because of the high temperature.

When using the DARK ROCK PRO 5, the full load temperature of the CPU is also basically constant at 97 ℃, and there is still no frequency reduction, which is very good for the air-cooled radiator.

three Performance and mute

It is worth mentioning that the DARK ROCK series radiators also have excellent noise control performance, which is due to their high-efficiency silent fans. In the noise test, we unplugged all the chassis fans and fixed the speed mode of the CPU heat sink in the BIOS without PWM adjustment. Since we are in a relatively quiet place, the test results are only for reference. Let's first look at the noise value of the current test environment, which is about 36dBA.

In the silent mode, the noise tester shows that the noise of the P gear of the DARK ROCK ELITE is 39 dBA multipoint, and the noise of the Q gear is close to 38 dBA. The difference is not significant, and it is very quiet.

The noise of the P gear of the DARK ROCK PRO 5 is about 39dBA, and the noise of the Q gear is about 36dBA. It can be seen that the noise of the two radiators is basically the same when the CPU is idle.

Next, let the fans of the two radiators run at full speed. The wind noise is indeed much higher than that of the silent mode, but there is no need to worry about the feeling of "takeoff" of the helicopter, and if the toaster test is not conducted, there will be no full speed operation; The noise tester shows that the noise of DARK ROCK ELITE is about 58dBA in P gear and about 50dBA in Q gear. It can be seen that this gear is very effective.

The noise of the P gear of the DARK ROCK PRO 5 is about 56dBA, and the noise of the Q gear is about 47dBA, which is quieter than the DARK ROCK ELITE.

four Summary

Many DIYers are superstitious about water-cooled radiators, but in fact, the performance of high-performance twin tower air-cooled radiators is far beyond imagination. For example, the two products of Be quiet, Moreover, due to the small number of fans and the use of (be quiet!) exclusive technology blades, the mute effect is also very ideal, which can be said to be a model of high-end air-cooled radiators. However, since its height reaches 168mm, you must confirm whether your chassis can be installed when you buy it.
