Just leave them to it, you can't help those who do not wish to be helped.

I'm happy knowing I have the best performing blocks, pumps and radiators in my case.

I don't get all this fancy control crap though. Don't know about you but at 7v fans cool the radiator enough through hell and back and my motherboard will shut down my system if the pump fails.

Heck, I can even script ATi Tray Tools to shut down the system if the GPU reaches certain temperatures.

Aqua-PC's - no offence but you're not actually going to recomend anything other than what your shop stocks, so really the ignorance point is going to be moot.
