Thermaltake Bigwater 745 - Dual Rad cooling

The single radiator fits fine in the PCI-Case Nitro, and there are some specific dimensions to check for if you want to install this radiator internally: 122 x166 mm. As long as you have a 120mm fan port at the back, and the space specified, you should be OK to install this Rad internally.
The CPU block didn’t require the motherboard to be removed for skt939, which is awesome. I really thought it would be necessary, but not so. Remove the standard mounting bracket for the stock heatsink, and the CPU block just screws in to the screw mounts on either side.
The Pump/Res unit wouldn’t fit in the floor of my case, but I managed to find room - by removing my redundant floppy drive (it wasn’t even plugged in anyway…). The thing above is the Aquabay M4 with a hard-disk installed another Thermaltake H2O accessory.
The Dual Radiator comes with quite a long cable, and since I was out of room in my case, I decided to place it on my desk instead. All I had to do now was install the tubing.
The barb system that Thermaltake use is great. However I would suggest that you check all the barbs are tight into each component before installing any of the tubing. This should be done with any kit as they could come loose in transit, and I found a couple of parts needed a bit of tightening. With that done, the tubing went on fairly easily, and was absolutely leak-proof.
The kit comes with a rear slot bracket to allow the tubing out of the case.
So there it is with everything installed. Of course my printer needs to go back on top of the case, so the rad can sit on my desk.
From there, it was just a matter of filling the unit. The lid on the pump screws off and just add the coolant while powering the pump separately from the PC for a couple of hours made sure it was leak free. Because I used all the tubing, as well as an extra component, I needed to add some de-ionized water as well.
I did have a problem with the dual radiator though. All the components in the system have a very good barb system, and the barbs sit very firmly inside each component. However with the radiator it was not so successful. The barb unit can be tightened too much onto the radiator, causing the seal to push out a bit and leak (it is fine in the picture above).
I discovered this when moving the radiator around - something you can’t do with the other components anyway - but luckily it isn’t inside the case, and it was only a very small leak (a drop or two). On the other components the seal isn’t able to compress out, so you can tighten them up as much as you want.
