How does liquid cooling work?

See section operating guide.

How do I initially start up the system?

See section operating guide.

How advantages does liquid cooling offer me over conventional air cooling?

See section operating guide.

Can I change the order of the parts of the circuit?

We recommend that you install the water blocks in order of heat generation, normally beginning with the CPU. The order of the following blocks may be altered, taking into account the ease with which the pipes may be connected.

What can I do to prevent the BIOS from detecting that the CPU fan is missing?

If the CPU fan sensor of your motherboard has been activated and there is no fan or pump connected to this sensor, the alarm will sound during start-up. In order to avoid this, you may deactivate the sensor in your BIOS configuration (see the motherboard manual) or, and this latter option being recommendable, use a recirculation pump which has a revolution counter connector (a tachometer) so that the motherboard is able to warn you of any faults on the pump. If neither of these options is possible for you, you may try to connect a fan with a tachometer which you have available on your computer, when connecting the CPU fan.

What advantages does using G1/4 connectors have over G1/8 ones?

G1/4 connectors have a greater internal diameter than G1/8 connectors and therefore reduce blockages in the flow of coolant by passing through them. Loss of charge on the circuit is thus reduced, this meaning the pump drives a higher flow of water, and thus enhancing the performance of the cooling system.

What happens if I connect the inlet and outlet of the blocks the wrong way around?

Blocks at Ibercool Water Blocks are designed in a way so that the flow of water circulates in the direction which is marked on each one. If they are not connected in the way shown, the block’s performance level may be jeopardized.

Can I connect various fittings and adapters in series?

When installing the cooling system, you may use various fittings and adapters to make connecting the parts of the system easier, even making use of various adapters in series in order to achieve the necessary angles.

If I install various blocks, should I change the pump and radiator?

In order to select a suitable radiator, you will have to take in account the amount of heat generated by the system. The use of more powerful and larger or better quality pumps and radiators will improve the cooling capacity of your system, meaning the water blocks will remove more heat from the various parts of your computer, and thus allowing for a greater number of these to be efficiently incorporated.

How do I know if the instructions which come with my block are the most recent ones?

You may download the latest version of the instructions for your Ibercool Water Block from the products page on our website.

My graphics card is compatible with the ICE chipset block and the 4Ways VGA block. Which one is more advisable to use?

The 4Ways VGA water block is a high-performance block especially designed for graphics cards. The ICE chipset block is a universal block, compatible with a whole host of graphics cards, this being a more economical way of cooling your graphics card, with a greater level of performance in comparison to conventional air cooling, but not quite reaching the level of performance of the 4Ways VGA.

Should I increase my power source when installing a water cooling system?

The power pumps tend to use is between 10W and 26W, which is what one or two hard disk drives (HHD) usually use. Radiators use the same amount of power as the fans connected to them, but you must bear in mind that conventional air-based cooling fans are disappearing, which is why the increase in power used by the system may be taken to be the equivalent to the power of the pump.

How much can noise be reduced by with a water cooling system?

The noisiest parts of computers are the fans of conventional air heat sinks. When these are replaced with a water cooling block, fans are placed only on the radiator, this being larger, which is why they are able to drive a greater flow at a smaller number of revolutions and thus emitting less noise. The pumps are relatively quiet (between 20dB and 40dB), which is why the noise of your computer may be significantly reduced.

Can I install a water cooling system on any computer?

The size of conventional towers allows for the installation of the parts which make up a cooling system (pump, reservoir and radiator) with various possible configurations. Installing the radiator is easier if the tower has input and output openings in the pipes leading to the radiator, or if it is designed for extractor fans to be placed on the back or upper part of the tower.

How can I prevent the growth of microorganisms?

You must add additives to the coolant (distilled or demineralised water) to avoid the growth of microorganisms which may obstruct the cooling circuit.

Can I use any other kind of liquid, such as alcohol, glycol or oil?

We recommend the use of distilled or demineralized water as a coolant given that the use of other kinds of liquids may damage the various parts of the water blocks or the rest of the parts of the circuit. Distilled water is able to absorb heat better than alcohol, glycol or oil, which is why it is more effective than any of these.

Is it true that distilled water does not conduct electricity?

Distilled water does not conduct electricity, but impurities from the circuit may be dissolved in the water, thus increasing its electrical conductivity. The main reason for using distilled water in water cooling systems is to reduce the risk of corrosion and the growth of microorganisms.

How do I fill the reservoir up?

This depends on the type of reservoir and its installation, but generally speaking we recommend that you fill the reservoir up when the computer is not connected to the power supply and do so using a funnel to reduce the risk of accidents happening.

What pump do I need?

The use of a higher capacity pump allows the circulation of a greater flow of coolant which boosts the exchange of heat on the water blocks. The installation of various blocks on your cooling system will mean greater loss of charge, which will reduce the flow circulating through them. Therefore, the use of a pump with a greater capacity is advisable.

What radiator do I need?

Each radiator has an optimum heat evacuation capacity, therefore the heat generated by the various parts of the computer to be cooled must be taken into account. The radiator's capacity also depends upon the number of fans installed and their specifications.

What should I do if the pump is noisy?

Assuming the pump is not faulty, this may be caused by vibrations it transmits as a result of poor installation or air circulating inside it. We recommend that you make sure the pump is correctly fixed to the tower and that there is no air in the circuit. You can also install an anti-vibration pad on the pump's fixture.

Do I need to put fans on the radiator?

The radiator will expel more heat into the air if it has fans which boost the flow of air. All radiators have connections for fans.

Is it better to have fans blowing or drawing in air?

The installation of fans inside (blowing) provide greater evacuation of heat, but may cause more noise due to the turbulence generated.

Could condensation occur in my cooling system?

No, as long as active chillers are not installed on the system, as the temperature of the entire cooling system should never be below ambient temperature.
