Thermaltake Bigwater SE - Thermaltake Bigwater SE
The radiator is cooled with a 120mm x 25mm fan, which, if used with the supplied expansion slot-mounted controller, can be set anywhere between 1,300 and 2,400RPM. No details are quoted for the fan but it’s very similar, if not the same as the fan is used on Thermaltake’s Big Typhoon cooler and this is good to around 54cfm of air.
Two screw-lock connectors sit on brass extension pieces at the top of the radiator, one of which wasn’t tight when I checked it and needed to be pinched up slightly. Don’t go too mad, as these brass couplings use ‘O’ rings, so a good, hard tightening by hand or a fairly tame turn with a spanner should suffice.
The water block is a fairly traditional two-piece copper and acrylic affair with the water transported through an S-shaped channel machined into the copper. A blue LED is also employed, sitting in a hole cut in the acrylic top. This requires a feed from a spare three-pin motherboard header or four-pin Molex to three-pin adapter.
The base of the block was flat but not particularly smooth, though it’s unlikely to impact on cooling efficiency.
The final part of the kit is the pump. This comes built into a sealed, box-like smoked plastic housing measuring a rather compact 66 x 61.5 x 36 mm. Inside the pump enclosure is a blue LED which is partly cosmetic and also serves to confirm the unit is receiving power.
The pump generates a virtually inaudible 18dBA of noise while pumping a relatively tame 90 litres of liquid per hour. This may seem like a fairly lowly throughput from the pump but the extra heat picked up due to the water’s slower passage through the water block is balanced by the extra cooling it gets by spending longer in the radiator. Provided radiator and water block are well matched it should actually make no difference how powerful your pump is.
The pump is rated at 12V DC and is powered directly from an available four-pin Molex connector.
The kit includes a 500cc bottle of UV reactive coolant with corrosion inhibitors and Thermaltake recommend using only its coolant. You’ll need about 400cc for a complete initial fill leaving 100cc for further top-ups. Additional bottles can be purchased from Thermaltake.
