I bet fans are looking pretty appealing now eh ? :lol: I've pretty much conquered the fan set ups. I have so many different fan configurations and optional fans in my current machine (front fans, side fans, rear fans, top fans, harddrive fans, internal fan tornados from the Antarctic) I've been able to OC my Q6600 to almost 4Gb and keep it under 60c; with the help of Riva Tuner adjusting my fan speeds at various temps. But that's not balls to the wall. With the right adjustments to maintain an interrupted airflow, the Antec 900 has turned out to be beautiful for air cooling. Now it's time for me to graduate to water cooling and learn something new. And no more mid towers for me; I need room to move and play when putting my future machines together. |

Yep, Mobster is right - running liquid in parallel is OK, provided all the blocks are the same. So you could parallel two GPU blocks... but trying to get four different ones running parallel isn't really gonna work. |

Current thoughts (cause you know things are going to change before I start working on this in March of 2010)... GIGABYTE X58 Extreme Mobo Cooler Master Cosmos 1000 case GeForce 295GTX x2 So there's the skeleton with video. My thoughts are to mod the inside top with two radiators. Inside there is plenty of space to use the lower 5.25 bays to hold two pumps. I'll use two verticle resevoirs between the motherboard and the bays (lots of space there if I wire the case right). I'll have one pump, resevoir and radiator running coolant to the main GPU (01); as even in SLI mode the first GPU seems to always run the hottest as not all apps use the SLI function to its fullest. The second pump, radiator and resevoir will go the GPU02 and the CPU. With the Northbridge covered by the heatsinks on the X58 board, a couple of small fans to keep a direct flow in the case should be more than enough to worry about heat within the case. I'll most likely have a couple 120m fans in the front and a couple just under the radiators blowing up. Now to look at some water cooling gear. As suggested, I want to try and keep it all copper components. Any suggestions would be appreciated. For the radiators, they need to be thin to fit inside at the top or a nice one that I can mod to sit on top of the case that can handle two flows. But I was going to go for an entirely inclosed system. |

Current thoughts (cause you know things are going to change before I start working on this in March of 2010)... You're going to need a really big case if you want an enclosed system. You're better off building an external radiator system. Pumps, reservoir, and blocks can all go in the case, but you're going to need at least 2 large radiators to get rid of all the heat absorbed into the water. You can do the system in circulation like I stated, and use 2 dual-120 radiators. Triple would work even better, especially with the dual-120mm radiators. Reservoir->Radiator->CPU->NorthBridge->Radiator->GPU0->GPU1->Radiator->Reservoir Mmm... triple cooled goodness. However you decide to build, you're not going to find "thin" radiators. Most radiators are as thick as a fan, and for good reason. You don't want to restrict flow through devices. That's why when you build a watercooling kit, you typically want to go with either all 3/8" or all 1/2". My old kit was 1/2", and it provided better flow over my CPU, never got over 45c with that kit. Prefab kit, shipped together, all copper. Great setup, they don't sell them anymore though. So... Yeah. Lesson today, you can never have enough radiators, and DON'T mix sizes, unless you like the smell of dead pump after only a year. EDIT: Oh, and never run anything in parallel besides video cards, and make sure when you do that, you T off the line right next to the cards, and then T them back into 1 line on output. |

Do you really need a radiator before and after the reservoir? So how many pumps and where? Reservoir > Radiator > Pump? > CPU > Northbridge > Radiator > Pump? > T-line > Parallel GPU0-GPU1 > T-Line > Radiator > Pump? 1 Reservoir 3 Radiators 3 Pumps? Overall, that sounds much more managable than was I was picturing; thanks. |

[quote]Reservoir->Radiator->CPU->NorthBridge->Radiator->GPU0->GPU1->Radiator->Reservoir Don't have to worry about the Northbridge on this mobo.

Reservoir > Radiator > Pump? > CPU > Radiator > Pump? > T-line > Parallel GPU0-GPU1 > T-Line > Radiator > Pump? 1 Reservoir 3 Radiators 3 Pumps? Overall, that sounds much more managable than was I was picturing; thanks. With the setup I was talking about, you should only need one big pump, right behind the reservior (where it should be). If you want to be certain you're getting good flow though, you would want to put one on the other side of the radiator after the GPU parallel. The multiple radiators is to expel as much heat as possible. The one after the reservoir is to expel any warmth that might be in the tank, the one after the CPU to remove as much heat as possible before transferring it onto the GPUs, and before the tank as this is standard practice. (Who the hell wants a tank full of hot water?) With pumps in mind, here's the 2 optimal setups: Res->BigPump->Rad->CPU->Rad->GPUs->Rad->Res With this setup you want a big pump, this is where it might be acceptable to use a 1/2" model pump for 3/8" setup, you get more pressure on the line, but with the amount of line you have to go through, it should equal out. Res->SmPump->Rad->CPU->Rad->SmPump->GPUs->Rad->Res This is the dual-pump setup, and it's a good idea to keep them the same size as the rest of the kit 1/2 or 3/8th, and with this you can use low/adjustable flow pumps to keep the pressure even across the CPU and the GPUs. This setup will more than likely create bubbles though as there will be a positive and negative pressure influence in the CPU water block, allowing for the water to become frothy in the teeth inside the block. I advise the bigger single pump setup, as it will reduce maintenance, and keep pressure high across the line, thus, helping to prevent bubbles from forming in the waterblocks. And don't even THINK about using smooth blocks for "increased flow", as they won't transfer most of the built up heat. The smooth blocks are meant for purposes of reversed cooling such as in my Peltier kit, whereby the cool side is attached to the waterblock, and the hot side of the peltier to a heatsink. Also, if you have the money, you might actually want to look into a single or double radiator system, accommodated with Peltier coolers (thermo-electric), on each device. CPU and GPUs. Though, finding a Peltier which works on a smaller die might be a problem. |

Ok, here is my first run at building a water cooling system. From here I can compare units and pricing. I went with a 3/8" system as there doesn't seem to be a lot of support for a full 1/2" system without adapters.

Found those Peltiers you were talking about: http://www.frozencpu.com/cat/l2/g30/c105/list/p1/Liquid_Cooling-Peltier_Coolers_TEC_Coldplates.html EDIT: Found a good article on Peltiers http://www.blazingpc.com/forum/showthread.php/peltiers_101-16410/index.html?s=5f7a37c57289d6ecce54e9267065be00&t=16410 |

Hi I am also very interested in water cooling but every time I start reading about the setup, the different hardware, connectors and so on, I close all windows and do nothing. I think as long as I am not a overclocking freak I should go better with normal airflow in my case. The only questions left in my mind is do you need to refill the water once its running? If so, how often? What is the good and what the bad side on running water cooled systems? Sorry for that noob questions :oops: |

a very small amount seems to evaporate from the systems. you might need to add 20ml a year or something daft like that. nothing much. my system holds around 700ml of liquid, with no leaks i just had a small amount go "missing" over the course of about 1 year or 16/18 months, i cant remember now |
