OK thanks, I'll take a look at those two.
Not looking for amazing performace as I don't really overclock anything these day, just want it quiet really. The D5 looks as though it would fit where my current one is best, although I suppose the other one is so small that you could fit it anywhere.
What's the best tubing these days? I've not had to buy anything for so long I am so out of what is good and bad!
Other parts of my setup are Swiftec G4 (the original one by Cathar), DD Maze 4 and Thermochill 120.3 if that makes any difference.
