I am going to be in the states in about a month-and-a-half, and I want to watercool my Core i7 920. Since watercooling here is rare, expensive, and next-to-impossible to find, I plan on buying parts over there. I have never built a watercooled system from scratch before, although I did toy with a couple of them in the past. This means I don't even the slightest idea where to start, nor even what the brand-names are (The only two I even know of are Thermaltake and Danger Den, and I know Thermaltake watercooling sucks). My case is the Nzxt Tempest and I really want my i7 to run at its current settings (3.76Ghz/1.18v) around 55-56c at load (That's approximately 10c drop from the Mugen 2 with two 120mm Slipstreams I am running at the moment). I have no idea whether this is a reasonable wish or not, because like I said, I am a total watercooling n00b. I did pick up some of the jargon along the way, so here goes: I can reasonably spend up to 400-500$ on the cooling setup (I think it should be enough and then some), and I have the room to make and use an external rad-rack. Otherwise, I believe that three 120mm rads (Or one and another dual one) would fit in the Tempest (One on the rear, the two on the top), but I would rather unclutter the inside of the case, so if building an external rack is a reasonable move, I'd rather do that (I've plenty of experience working with wood, so I can make something nice easily enough). Only the CPU and chipset will go under watercooling (The motherboard is the DFI LP DK X58-T3eH6) for the meanwhile (My HD4870X2 has the Accelero Extreme 4870X2 on it, and it is quiet and cool). I would prefer the setup to be slightly on the overkill side as far as cooling capability goes because I plan to OC higher and I'd like to keep temps as low as I can (The local climate is quite hot, so I can't go over 4Ghz with air cooling for 24/7 operation). Links/Screenies of shopping carts with the stuff would be really appreciated, but any help is more than welcome. Thanks !
