Can anyone rate the primochill Typhoon III?

[4GHz_or_bust]

I've had the T3 rev 2 for a few months now, using Swiftech 655 pump. Originally I started with 1 radiator and CPU block then 2 months ago I did a semi-rebuild to include second radiator and 2x GTX 470 water blocks. The only thing inside that are distilled water (half gallon total) and a few drops of PT Nuke.

All a single loop not dual loop even though the reservoir supported it directly. From what I read, there were little difference anyway between single and split loops.

The case it's mounted inside is Lian Li K62 (actually under Lancool name) and the way the drive mount are, the drive are on tabs on the side that allowed a bit of side to side movement. The bay is not touching anything above or below. All screws and fittings on the reservoir are hand tightened, no more than 1/4 turn after it becomes hard to tighten. No wrenches, no hammer, no ratchet, nothing but fingers and included allen tool.

I have not seen any sign of crack at this time.

Heat Killer 3.0 block for AMD
2x EK FTX-470 blocks
2x Swiftech 320 QP
Swiftech MCP-655 (non variable)
Primochill green tube

EDIT: would help to mention temp too if anyone were interested. GTX 470 didn't go past 45C and CPU (overclocked to 4GHz) didn't go past 40C. A far cry from stock GTX 470 cooler that used to hit 99C and cheap looking AMD cooler that allowed 55C to 60C on stock speed (yikes) and could never handle overclocking.
