Our products should be available at any distributor of PC components. A list of possible shops can be found here.

Yes, but only in the case of spare parts – they are available directly from our support ([email protected]). Other than that we do not sell directly to end customers, only to specialized dealers.

There are no general requirements – we support modders, eSports enthusiasts, LAN parties, influencers and many other partners. If you are seriously interested in a cooperation, please use our sponsoring contact form. After reviewing your proposal we will get back to you if we see a chance for cooperation.

The fans that are used on graphics cards usually do not follow industry standards, but are specially developed and optimized for use on the respective GPU - which makes use of standardized components such as be quiet! fans very difficult.

If your motherboard does not have an ARGB connector, there is a so-called ARGB converter available from several manufacturers that takes care of this task.

Almost all products of the be quiet! brand are granted a warranty period that far exceeds the statutory minimum period for manufacturer’s warranty claims.

In most cases the manufacturer’s warranty is valid for 3-5 years from the purchase date.

You can determine the precise warranty period for your particular device by following this link: be quiet! manufacturer’s warranty

Yes and no…
To qualify for be quiet! manufacturer’s warranty services two conditions must be met:

1. You must be the original retail customer who purchased the product
2. You must possess an invoice for the device you wish to make a claim for

If you cannot fulfill these criteria then unfortunately you have no right to claim under manufacturer’s warranty.

If you acquired the device from an online dealer, in many cases you are able to retrieve an invoice directly by logging onto your customer account, alternatively you can request it from your dealer.

If it proves impossible for you to obtain an invoice for the device, in certain cases we may grant you a special “accommodating procedure” given the serial number (such a procedure is generally excluded for devices in the case fans and CPU air coolers product groups).

In such cases the decision is made at our discretion, from which no general right to warranty may be construed.

This behavior occurs when a protective circuit in the power supply is triggered. It could be prompted by a short circuit or fault current in the system, for example.
If you purchased a power supply with modular cable management, use of the wrong cable is frequently responsible this behavior. Please note that only cables for the power supply that are approved by be quiet! should be used. The use of cables from other models or earlier series, including cables from other manufacturers, can give rise to this behavior.

Did this help you solve the problem? No

To eliminate the possibility that the problem is caused by external interference, we recommend you first disconnect all peripheral devices that are not directly needed to start the computer (printer, display, keyboard, etc.) and detach connectors for components (HDD, SSD, graphics card, USB panel on the PC case etc.) from the motherboard.
The only components that remain connected to the motherboard should be the main 24-pole ATX connector or EPS 12V CPU P4 (P8), the CPU, and one main memory bank. If the computer now starts it may be determined, by a subsequent process of elimination, which component is causing the non-starting.

Did this help you solve the problem? No

Unfortunately, further elimination of the fault is not possible with just this system.

If you have the possibility, we advise you to test the power supply in an alternative system.
For this connect the power supply using the main 24-pole ATX connector or the EPS 12V CPU P4(P8) to another motherboard.
If the alternative system starts using the power supply then there appears to be a fault in one of the components you tested it with.
Please get in touch with the motherboard manufacturer and describe the problem to them.

Did this explanation solve the problem? No

We are unable to rule out the possibility of a fault in the power supply. Please contact our Service staff.

If your power supply is still within the warranty period, please get in touch with our Service staff.

Of course the fan should give you the same discreetly quiet performance for the whole of its warranty period.

If the warranty period for your device has already expired, we are unfortunately unable to offer you a replacement power supply.

For reasons of legal liability and technical insurance we are prohibited from supporting the independent repair of electrical appliances.
This includes any actions that would call for you to break open the power supply.

We are sorry!

This behavior may result from a variety of causes.
Sporadic system crashes can be caused by faulty hardware or by faulty software.

In our experience the most common cause for this problem is badly setup overclocking.
Try loading the “default settings” in your BIOS, save these and check whether the system now runs without crashes.
This measure may also prove successful when you do not use overclocking.

Did this help you solve the problem? No

When crashes are related to an overheating power supply, they are usually caused by tripping the over temperature protection (OTP).
Ensure a gap of at least 20cm exists between the rear of the computer and the nearest obstruction (wall, desk, etc.).
Lacking a sufficient gap, the warm air from the case is unable to escape properly and this can lead to a build-up of heat.

Did this help you solve the problem? No

The fan on a power supply is largely responsible for preventing a build-up of heat in the power supply.
All of our PSUs are active power supplies. That means that the PSU fan spins all the time. Check whether the fan of your be quiet! power supply is running.
If the fan is not turning, sometimes it helps to prod the blades of a stuck fan (use a pencil or similar, not your finger).

Did this help you solve the problem? No

If the fan refuses to budge, it can point to a fault in the internal fan regulator of the power supply.
In this case then please get in touch with our Service staff.

The cable is probably not faulty. It is important to realize that although the cables offered in stores as our accessories are compatible with all the latest be quiet! power supplies, this does not apply to older PSUs.
The be quiet! S-ATA & multi-cables currently offered are compatible with the following series:
be quiet! Pure Power L8 and newer
be quiet! Straight Power E9 and newer
be quiet! Dark Power Pro P8 and newer
be quiet! Power Zone Z1 and newer
Note: the higher the series number, the newer it is.

In some cases the connectors of the latest cables will also fit in older series than those listed, but the assignment of pins is now different from older PSUs.
Plugging in such a mismatching cable would likely trip the short circuit protection (SCP) of the power supply, preventing any PSU output voltage.

This depends heavily on the models. Please contact our support ([email protected]) for detailed information.

Yes, that is completely normal.
When high-powered PSUs are switched on they generate an inrush of current, which can amount to several times the nominal rating of the device.

Such an excessive surge of current will sometimes result in tripping the electrical circuit-breaker that protects the part of the building’s wiring your computer is plugged into.
In order to prevent the possibility of this happening, we built  inrush-current limiter into our PSUs. The “click” you can hear is the inrush-current limiter activating at start up – and deactivating at shutdown.

You do not need to worry there, this is a completely normal behavior. If you turn off the power supply fully, capacitors & coils discharge completely. If you then turn the power supply back on after a while, these components are loaded with the inrush current, which leads to wear of the materials in the long run. For this reason, we have set the power supply to a 5V standby voltage, even if the toggle switch is set to 0, which ensures the longevity of the power supply.

A separate mesh front is available for the Silent Base 801. In some cases, the mesh front of the Pure Base 500DX can also be used on the Pure Base 500 – please contact our support ([email protected]) to find out whether your Pure Base 500 case is compatible. Other separate mesh inserts are currently not available.

After you have connected all components correctly, hold down the LED color switch button on the I/O panel of the case for about five seconds, which synchronizes all components. However, this is not possible with all cases!

The following cases are prepared for a vertical GPU installation:

Light Base

Dark Base 701

Dark Base 700

Dark Base Pro 901

Shadow Base Serie

Silent Base 802

Silent Base 801

Silent Base 601

For the vertical installation of a graphics card, a so-called riser cable is required to connect the graphics card to the motherboard. We at be quiet! offer you a solution, the Riser Cable.

We have prepared several videos to answer this question case-specifically:

Light Base 

Dark Base Pro 901

Dark Base 701

Dark Base Pro 900 rev. 2

Silent Base 801

Silent Base 802

The SSD is mounted on the outside of the frame, not the inside! We have prepared a helpful video explaining the mounting.

Unfortunately, this problem mainly arises from an oversight in the manual.
The PCB (fan controller) also needs to be supplied with power. To do this connect the circuit board to the PSU with one of the unused S-ATA connectors.

Did this help you solve the problem? No

We are unable to rule out the possibility of a faulty device. Please contact our Service staff.

We’ve compiled all of the measurement data for each cooler in a dedicated document which you can find in the respective downloads area on our website.

We’ve created the motherboard check tool on our website specifically to answer this question. In case you can’t find your model you can also always contact us, and we will try to check your compatibility manually.

We check compatibility to new Intel and AMD sockets on a regular basis. If new mounting kits become available we will communicate so to the specialized press and through our website as well as our social media channels.

We're convinced we delivered the optimal fan for the job with the cooler. Changing the fan in the vast majority of cases will have a negative effect on the cooling performance.

It's not recommended to change the orientation of the cooler in such a way. Anyway if this is needed for your built it is possible to purchase a mounting kit with brigdes for a different orientation for AMD Systems. Please contact our service.

Some mainboards present this error when the fan speed is too low. You can usually fix this by manually increasing the minimum rotation speed or by deactivating the error message in the BIOS.

You will achieve the best cooling performance by installing your Top Flow cooler so that the heat pipe ends point in the direction of the RAM banks.

Here’s an explanatory video.

If you intend to replace our enclosed fan with another model, the long clips can be used for this. They are designed for fans with a diameter of 120mm and a thickness of 25mm.

Liquid metal is only compatible with coolers with copper or nickel-plated copper baseplates on coolers. Therefore, all our water coolers and our Dark Rock product line are compatible. Coolers with HDT technology are incompatible and would be damaged by liquid metal. Please research before using the kind of baseplate your cooler has before considering this option.

If you want to control the fans via the PWM signal, you must connect the fan controller to a PWM-capable header (4-pin) on your motherboard. Then you need to set the switch on the front panel to "Auto". Once you have done that, you must set the selected fan header (which you connected to your fan controller) to PWM mode in the BIOS. Save and restart.

Very slight movement achievable by hand, like twisting and back and forth sideways movement, is normal since the screw holes on the mounting bridges are bigger than the screws. If you have upward and downward movement (towards and always from the CPU) or a lot of play, this is not normal, and you should contact our costumer service.

• Check the coolant level and if necessary top it up. The right way to do this is described in the installation instructions. When the coolant level is too low, it leads to more noise and can damage the device.

• The radiator must be mounted in a suitable position in the case to prevent vibration and turbulence in the airflow. Please also note any advice given by the manufacturer of the case.

• Make sure that no tubes or cables come into contact with fans in the case. Bubbles of air may have become trapped in the pump’s impeller during transportation. It may be possible to free the impeller by repeated switching on and/or loading cycles.

• Our all-in-one water cooler uses an aluminum radiator, which is originally silver in color. The radiator is lightly tinted with black paint, which from certain perspectives might not be entirely opaque. This outer paint cover does not affect the cooling performance in any way.

• Our all-in-one water cooler is a cooling unit intended for the cooling of processors and made solely for that purpose. If you plan to open up or modify its closed system we are no longer able to guarantee its functionality or cooling performance in any way. Please only allow authorized service technicians to undertake repairs. Opening the device besides of the refillport voids the warranty.

• Should you experience any other problems with the water cooler, please get in touch with our service department. You will find our contact details in the manufacturer’s information section.

"PWM" is a term from electrical engineering, and stands for "pulse width modulation". This allows you to control the speed of a fan almost freely, which is not possible with non-PWM fans. A detailed description of the differences can be found here.

Following air coolers can easily be upgraded with Light Wings:

• Shadow Rock 3
• Shadow Rock LP
• Pure Rock 2

On the Shadow Rock LP and Pure Rock 2 we strongly recommend the high-speed version.
If your system provides a second CPU fan connector you can use Light Wings 120mm as an additional fan on the backside of the heatsink.

These coolers provide additional fan brackets in scope of delivery:

• Dark Rock 4
• Dark Rock Pro 4
• Dark Rock Pro TR4
• Dark Rock Slim
• Shadow Rock Slim 2

We do not recommend to exchange the fans on any Dark Rock cooler as they use custom sized Silent Wings that are designed for a maximum of silence and performance the Light Wings cannot achieve.
Please note that the operation noise can differ with Light Wings installed as they have other performance curves.

To reach the same noise-performance level as with the standard fans, the CPU fan curve need to be configured.
