Thermaltake's Bigwater range of watercooling systems have been around a while, but the company claims its latest model - the Bigwater 760 Pro - is worth a second look even for those familiar with the company's offerings.

Those who have seen the Thermaltake Bigwater 760 Plus will find a certain amount of familiarity in the design of the Bigwater 760 Pro: the design uses the same full-height 5.25in layout, taking up two optical drive bays in your rig, packing all the required components - pump, fan, radiator and reservoir - into a black-finished case. As with the Plus, the Pro model includes a front-accessible fan control - but where are the improvements Thermaltake promised?

To start, the design now includes a clear liquid level indicator to make it easier to monitor the status of the 270cc reservoir, while the radiator - still a single-fan 120mm design - has been updated to provide improved cooling. The layout has also been shifted: while the previous design had the fan on the top of the radiator blowing downwards, the new Pro model places the fan underneath blowing up - meaning the excess heat should be easier to vent from the case using ceiling-mounted fans.

The waterblock has also undergone a change, with the black finish of the Plus giving way to a mirrored silver finish to the copper cold plate - redesigned, Thermaltake claims, for a boost to thermal transfer efficiency and flow rates. The ultraviolet-reactive tubing from the Plus makes a reappearance, although this time in an improved material claimed to prevent clogging and kinking.

Finally, the kit now includes a 500L/h pump - the P500 - which Thermaltake claims provides a high enough flow-rate to extend the loop: while the standard kit includes just a CPU loop, the company is encouraging users to extend the system with GPU and memory loops as well. How well the 120mm radiator and low-noise 120mm fan - adjustable between 1,600RPM and 2,400RPM using the front-facing knob, and fitted with the same blue LEDs as its predecessor - will cope cooling an entire system, however, remains to be seen.

The kit comes complete with a universal mounting plate compatible with Intel Socket LGA 2011, 1366, 1155, 1156, 1150 and 775 and AMD Socket FM2, FM1, AM3+, AM3, AM2+ and AM2, and 500cc of UV-reactive coolant liquid with added propylene glycol. Sadly, Thermaltake has yet to indicate pricing and availability for the upgraded kit, but with the Plus model still fetching upwards of £130, expect the Pro to be priced to the north of £150.
