Introduction

I would like to thank Thermaltake for providing us the review kit.

We are going to take a look at a new Water Cooling Kit from Thermaltake. They have been producing products for computer enthusiast since 1999. This new kit named the Big Water 745 is a revised version of the Big Water produced earlier by Thermaltake. Some knocks on the previous Big Water was that it was to small with its 1/4" ID tubing, to the smaller pump housed in the reservoir and just toward kits in general. Its performance was slightly better than a really good air cooler. Mainly for those new to water-cooling the first Big Water was a great kit to get your feet wet. I used the Big Water myself to cool my Dothan processor with great results.

The new Big Water 745 now sports 3/8" ID tubing along with a larger pump and liquid tank. The kit also includes two radiators with the original Big Water single rad design still being used and with the additional dual 120mm external radiator. From the larger tubing size to a small change in the design of the copper waterblock this kit looks to be a great addition to the Thermaltake product line.

Features:

• World 1st liquid cooling system supports ATX / BTX motherboard
• Application for Intel P4 LGA775-Intel BTX platform and all AMD K8 series.
• Breakthrough design Radiator
  
1. Exclusive 240mm Radiator: High performance radiator with dual 120mm silent fan(1300 rpm) to improve thermal dissipation.
2. Remarkable 120mm Radiator: High performance radiator with a 120mm silent VR fan(1300 ~ 2400rpm).
3. Triple fans and dual radiators ushers in the next generation cooling capability.

• Superb liquid pump with 400 L/hr:
  
1. Silent and powerful P400 pump provides superb reliability.
2. The pedestal can be secured onto the case by screws.
3. The ceramic bearings significantly extend the life expectancy of the pump.
4. Thoughtful inlet and outlet design prevents air blocks from water flow.

• Exceptional Liquid Tank:
  
1. High capacity liquid tank capable of holding 350c.c of liquid for continuous usage.
2. Easy to refill.

• Second-to-none Copper Water Block
  
1. With the LED acrylic covering illuminates the CPU
2. Increased number of water channel within the water block greatly enhances the thermal efficiency.

• Durable 3/8" Tube:
  
1. Special material to prevent wear & tare from being clogged up from over bending.
2. User friendly installation, tool-less connector design.
