Sick and tired of deafening computer fans? Modern day hardware create a huge amount of heat and to deal with this we end up needing large heatsinks and high Rpm ventilators. Radiators are where the heat dissipates; the larger it is in size, the more surface area will be available to dissipate heat. For radiators I won't recommend specific models, since it is based on how much cooling performance you want. In theory, a single 120mm radiator can dissipate 150Watts, so 2 X 120mm radiator should handle 300Watts etc. Most radiators from reviews are pretty much neck-and-neck, with little variation in performance.


Normal water cooling is actually affordable for most people. An elementary package consists of a radiator, a Processor block, water pump, tubes and barbs. Larger sized systems can include addition components like a reservoir enabling one to top up water quickly, more blocks for additional components for instance graphics cards and chipsets can be found nevertheless they will need more radiator area for cooling. A so called water cooling loop has a radiator, processor block, pump motor and tank to hold water. On previous generations of motherboards, the memory controller (Northbridge) was part of the motherboard and this could get quite hot during overclocking, today's i7 platform has the memory controller on the CPU, so the only thing left on the board where the Northbridge was, is the chipset, or IOH (In/Out Hub). This generally runs quite cool for most of the time, but if you are running a pair of large graphics cards, the IOH can get start to get hot, whether it needs water cooling is entirely up to you, but my preference is to leave it air cooled on i7 systems. What is a shroud? A shroud is simply a device that allows the radiator fans to be slightly further away from the core of the radiator and this gives a number of benefits. Firstly, all 120mm fans have a "dead spot", in other words, if you place a fan close to the core, there will be an area in the centre of the fan that has no air being pushed from it, and of course, the cooling to that part of the core will be less than the outer areas that are getting the full blast of air. Raising the fan off the core by a few centimetres can help improve performance slightly, but also, it can reduce noise too. You can do an experiment with this yourself, grab a piece of mesh or some material and hold it up to the blowing side of a fan, the closer you get, the louder the wind noise will become, the shroud works in the same way.

GPU chilling, indeed water chilling a video card. By using a GPU water block you would get wonderful, like 46's C load tempretures dependant upon ambient ofcause. Most of these water blocks will be high-priced and in case you got a brand new graphiccard the block will almost certainly need to be swapped out too. Nevertheless in this way would certainly furthermore permit excellent overclocking and increased Frames per second in video games.

Beyond the diameter of the tubing, you just need to pick a color. Most sites that deal in water cooling sell pretty much the same PVC-based tubing. It works well, it's fairly cheap, and it's available in a bunch of UV-reactive colors. Some sites offer slightly more expensive Tygon tubing, which is more flexible and durable. Fittings come in barbed or compression styles. Both will work just fine, though compression fittings look nicer and are a bit more expensive.


Pumps vibrate, this is especially noticeable when they come into contact with hard surfaces, so if your pump is sitting on the floor of the case, or up against the side panel or motherboard tray, it will need some kind of insulation. There are lots of things you can use for this, from bubble wrap, to foam, to pieces of Neoprene - Pretty much anything soft, most pumps come with some kind of sticky foam mat, but they aren't that great. One of the best things that I've found is clear silicon sealer, available from all builder's merchants in large tubes for less than £1.50. Take a small baking tray or anything that will give you around 1cm depth and squirt the sealer into it and smooth over any peaks with a knife or credit card, leave it to set and then cut to the desired sizes. One of those large tubes should be enough to make several small squares, the same thing that is available to buy for around £5 each in shops. Also to make a water cooling system is a fun project, and if nothing else, a good reason to spend a lot of money. A home made system has huge expansion possibilities, and is also a long term investment. If you buy a new video card you can almost always use the same water block as you did with the old card, so even if the price is high when you buy it, the system works for a long time without any performance loss, which makes it a really good investment.
