Swiftech H20 Louder than air

[HatMan]

I have just installed the H20 120.1 system in my PC not for the extra cooling but for the alleged reduction in noise. Before I had three Amber 120 and the three stock Antec 3 speed, plus the 8800GTS fan running along with the freezer 7. Temps were always low but loudish, too loud for me to sleep 6 fit from it. The H20 is not a simple fit in a P182SE but I made brackets for it etc and it fits great. The pump is louder than all my previous fans running together and the speed keeps fluctuating every so slightly now and then. I have lapped the CPU and the base of the H20 and my current temps are 32ºc,32ºc,32ºc,35ºc. I still have the side off as I haven't decided whether to keep the H20 or how the hole in the side panel will be finished. Does anyone know if the pump needs to run in and thus get quieter? I must say that, in the believe I have installed it all correctly, I am not impressed so far.

Actually I have should have worded my initial post more precisely. The P182 is more than capable of accomadating the H20 but my DQ6 won't allow it because of the VRM heatsinks etc. I have swapped all my fans for four Noctua 120mm 3 x 800rpm and 2 x 1200rpm. I will drain the system again and try again. Thanks for the advice.

Ok, tonight I have completely removed and emptied the coolant from my system. I refilled it really slowly with the rad much high than the block. I powered it up and let it run for a minute, the topped up and checked again. The pump is making exactly the same amount of noise. I have written to SwifTech and sent them images of my install for them to appraise. Based on the fact I'll have to take the mobo out AGAIN, I figured I ask them first.

Anyone know why Speedfan gives some strange readings and inaccurate voltage readings? (Vista 64) Temp 3 is -3c and my 12v rail is at -8.04v!!!
