I am currently planning the construction of a new PC from scratch (dual Itanium2s) and am in the market for an alternative cooling source. I have done quite a bit of research, online, in magazines, in scientific journals and through various engineers I am in contact with. I have come down to two possible cooling units: either a water cooled or with a Peltier element. For those who are unfamiliar with these two types of cooling, I have included two links below which may be of interest to you. Anyway, I have more information than I could possibly ever want regarding these cooling systems, but I want first-hand experience. Have any of you ever used either a water cooled system or the peltier element? If so, what do you think of it? Would you recommend it to anyone else?
