Thermaltake Big Water 745

Radiators

The Big Water 745 comes with a 240 mm external radiator along with the 120 mm radiator. The dual 120 mm rad is external only, but with the single 120 mm it can be installed inside the case or outside. The external 240 mm radiator is exclusive to the Big Water 745 in the fact that it comes with stands to mount the radiator.


Both the front side and back have nice chrome cover grills. The sleeved 4-pin power connector cable that supplies power to the dual 120 mm fans stretches 45" (114.3 cm) which is more than enough.


The dual 120mm is a nice addition to the Big Water 745 kit. Something I noticed about the dual rad is it has the same slot for mounting as the single rad which if one didn't like the stands you can mount it in a different way. Perhaps adjustable stands so you could mount it on top of the case with clearance underneath. I for one will need to make room for it. On another note I noticed the dual rad doesn't have the fan speed adjustment as the single rad does. Not a show stopper nor hard to rig one up.


The single radiator is a carry over from the previous Big Water and can be easily installed inside the case or outside. Seeing how the dual rad is already outside the case I would think it would be easier to mount it outside as well. Use a little less tubing and not as tight of a bend.


The radiators themselves are in a black metal housing and come apart fairly easily and a blast from a can of air can help blow out any dust buildup in the fins.


Note that the back cover of the dual radiator has the slots for the quick connectors so if you don't like the tubing in the front you can flip the rad and connect the tubing from the back.
