well the new chip-con or whatever they are called (im NO good with names) are like -35C under full load but if the room temp is like 20C (it seems about right) think about that, have you ever taken out a cold drink (14C) in like 32C, all the liquid on the outside no matter how well it is bottled or if you dont spill (sometimes, u know) thats just a18C difference,were talking almost 50C in this scenerio, i wouldn't put anything but the best in my case if i had to use water cooling. And we all know only the few elite richers can afford 550 for water cooling :P
