Koolance PC3-725BK is the ultimate combination of cooling power in aluminum! Koolance's PC3-725 liquid cooled case system includes the 700W pro cooling system merged with a Lian-Li pc case. Dual 120mm radiator fans further reduce noise levels, while 3/8" (10mm) tubing tackles dual CPU, dual/SLI video coolers, and other demanding setups. The Koolance PC3-725 features a new Koolance LED display panel, which monitors 3 separate temperature channels- each with it's own configurable alarm setting.


  • Radiator fan speeds adjust automatically, or with 10 manual levels
  • Blue reservoir LED lighting
  • Top refill plug
  • Variable safety shutdown temperature
  • Easy-latch side door
  • Three interior zones to isolate hardware for better heat dissipation
  • Front and rear case perforations for improved ambient conditions
  • Sliding hard drive tracks for easy installation
  • Aluminum rolling casters with brake
  • Front USB 2.0 and 1394 Firewire ports
  • Includes front and rear 120mm case fans


Koolance coolers which use 6mm (1/4?) ID nozzles, such as the GPU-180-L06 video cooler, can still be effectively used in PC3-725 systems. Using a parallel tubing configuration with hose splitters will help maintain coolant flow rate through these systems. Appropriate hose splitters and both 1/4" and 3/8" tubing are included. (Please see the User Manual for more information.)

Safety Shutdown / Alarm Feature
If the temperature value of sensor #1 reaches 3ºC (5ºF) above the alarm temperature, the system will shutdown power to the computer. With default alarm settings, this means the system would shutdown if sensor #1 reached 58ºC (136ºF).

Included Hardware with all PC3 Series Systems:
- motherboard standoffs & insulating washers
- motherboard, slot card, 5.25” drive, and floppy screws
- hard drive mounting screws

Components Required:
Cooler kits such as the CPU, hard drive, and video/motherboard chipset are not included with Koolance systems. To operate the system at minimum, a CPU cooler is required. Other liquid components (such as the radiator, pumps, and LED display) come pre-installed. For more information, please call PCPowerZone customer service.

Koolance PC3-725BK Case: How it works (minus the Techno Babble)

The Koolance liquid cooled systems are comprised of the following components

  • Water Pump
  • Coolant Reservoir
  • Liquid Coolant
  • Water Cooling Blocks (minimum of a CPU cooler)
  • Radiator with cooling fans
  • Control Module with LED display board

Liquid Coolant is pumped from a DC powered water pump, which is either mounted internally inside of the Koolance reservoir or externally near the reservoir (pre-installed).

This liquid is pumped through 3/8" clear tubing to the first water block. The coolant will rush into the cooling block and absorb and carry away the heat that passes from the CPU to the base of the cooling block.

This heated water continues from block to block picking up more and more heat until it finally travels to the radiator. At the radiator, heat will be passed from the cooling liquid into the metal tubes/fins of the radiator. At this point the heat will radiate from the radiator and be dispersed by the cooling fans. The coolant then returns back to the coolant reservoir only to repeat the process again and again.

Cooling Blocks Not Included
The Koolance CPU cooling water block is not included with this Koolance case, you must add a cooler such as the Koolance CPU-330 cpu cooler to your PcPowerZone shopping cart in order to have this added to your Koolance order.

The default Koolance water cooling coolant line used in this Koolance case will be 3/8", please use 3/8" nozzles on your Koolance cpu cooler for best performance. Additional coolers can be added using either 3/8" or ¼" fittings as needed.

When using cooling blocks utilizing ¼" fittings on your Koolance case water cooled pc system, you will want to use the included Koolance tubing splitters (comes with all of our Koolance case's and Exos systems) to reduce the 3/8" tubing coming out of the Koolance water pump into dual, parallel ¼" coolant channels for various cooling block configurations. This helps prevent reducing the coolant flow rate within the coolant channel within your Koolance water-cooling system.

The Koolance Cooling system can be used with any brand water blocks such as Koolance, Danger Den, ThermalTake, Cooler Master, etc. The Koolance copper water blocks are electroplated with a thin layer of 24k gold to prevent a chemical reaction from taking place between the copper and aluminum within the Koolance cooling system, most of the other brand of water-blocks will not feature electroplated copper to reduce corrosion.

How long is the Koolance warranty?
Koolance covers their complete product line with one year of warranty coverage. In order to have a product serviced under warranty by Koolance, you will need to have a copy of your PcPowerZone purchase invoice for proof of purchase.

Can I use other liquid coolants within my Koolance cooling system?
Yes you can, but if you do use a non-Koolance brand coolant within your Koolance water-cooling system you will void your warranty.

Some coolants have been known to cause damage to various plastic components within some Koolance pumps and coolers with resin tops, take heed.

I used a non-Koolance coolant and now I need my Koolance product serviced under warranty for a part that did not come in contact with the coolant. Will my Koolance cooling liquid cooling product be covered by Warranty?
Again, once you use a non-Koolance brand coolant within your Koolance system any Koolance product used within the same system will have the warranty voided. In the end, it will be up to the manufacturer to make the final decision.

I tested my new Koolance PC4 based cooling system by dry running the pump; it does not work. What do I do?
You can NOT dry run any PC4 based Koolance water-cooled system! Not for 1 second or 1 minute! Never dry run any PC4 based Koolance pump as for this will destroy your Koolance water pump.

Water is needed to properly lubricate and cool a pump… you wouldn't (well most of us) run your car for any period of time without having motor oil in your engine… it is the same principle with the Koolance PC4 based cooling systems.

No coolant equals a DEAD PUMP! Once any Koolance PC4 based pump is ran without coolant, your warranty is void for the pump… replacement will be done at the users expense.

Can I use other brand liquid cooling blocks with my Koolance cooling system? Will it void my Koolance warranty?
Yes, you can use any brand liquid cooling block with your Koolance cooling system without voiding your warranty. This does not mean that PcPowerZone recommends doing so.

DangerDen water blocks are commonly used with Koolance cooling systems. Although DangerDen is known for good quality and cooling results, the copper base plates can potentially react with the aluminum used within a Koolance system since it is not coated with a corrosion inhibitor. Please monitor your Koolance system for potential corrosion when using any cooling block with copper exposed to the cooling circuit.

Another thing to consider when using some of the "other" brand coolers is that a lower quality, improperly designed water cooling block will often require higher pump pressure and flow rate to work effectively. The Koolance cooling blocks are designed properly for use with the Koolance flow rate, giving optimum performance.
