Thermaltake Bigwater 760i Water Cooling Kit

The unit

Thermaltake's Bigwater 760i is an internal water cooling solution designed to install into two open 5.25" bays.  You may ask why does it need two bays?  The answer is that the cooling fan, radiator, pump and reservoir are all inside this housing.  The face of the unit's housing is flat black with Thermaltake corporate and product badging labeled on as you would expect.  The upper section has a small screened area which serves as a fresh air intake.

Turning things a bit we see how the Bigwater 760i has slits along its sides to allow for installation into cases with optical drive shelf lips.  You also get a better look at the 120mm fan.  This is a variable rate blue LED number that turns 1600 to 2400 RPM depending on the selection made via a manual rheostat.  Fan noise is also rated at 16 to 20 dBA.  When the fan was running at low speed it was inaudible as opposed to high speed which was decided noisy.  So noisy in fact that it is almost criminal for Thermaltake to state the sound level at full honk is 20 decibels.  While I didn't have a sound level meter, I would guess it was three times that at full speed.

The air that is pulled in from the open screen area is blown down by the fan we showed you above.  From here the air is blown through this 153 x 120 x 35mm radiator.  Plenty of surface area here for cooling.  A point to certainly not be forgotten is that the air coming off of the radiator will be warm so proper case ventilation is an absolute must.

The reservoir and pump ladies and gentlemen.  The pump is rated at moving 500 liters/hour of fluid.  This is a far cry from the older 90 L/hr pumps we saw in the original Tt Aquarius H2O system.  The benefit of this strong a pump is so upgrades and accessories are possible.  Tt makes a number of water cooling accessories such as VGA water blocks, HDD H2O coolers, memory H2O coolers and the like.  Check out this page to have a look at how many different upgrades Thermaltake puts out.  It really is incredible.

The quick connect hoses were first seen on Thermaltake products with their Symphony water cooling system.  These no leak connectors allow the end user to 'unplug' the block from the main unit for maintenance, refill or the adding in of an upgrade.

Here was a surprise.  The variable rate fan we already showed you was a manual adjustment.  The rheostat that controls the fan's speed/sound level is near the rear of the main assembly and only accessibly by opening the case.  With a two bay bezel on the Bigwater 760i you would have thought Thermaltake would have placed it there but no.
