Ok, i've never done anythign to do with watercooling but i was wondering how does the amount of water pumped affect the temperature. Is more flow always better? I was thinking of putting together a custom water setup and i have a pump from a pond laying around. Would that be good, or would it be a stupid idea?

More flow is better as the water will be moved faster around the loop, therefore heat can be removed from the CPU and to the radiator to be dissapted faster. Some waterblocks are designed to be more efficient with more powerful pumps.

The pond pump is probably not best suited to this application. It depends on the GPH (flow rate, how many gallons [sometimes litres] per hour the pump can...er, pump) and the head (how high the pump can force water). If you can find these out we can see if they are good enough, but I doubt they will be. A pump designed for PC watercooling has the neccesary power and all the correct fittings and power connectors which will elminate a lot of headaches from modding a pond pump

Ive done the pond pump mod and it is a pain in the um.....bum. Unless you want to use a descent size reservior and have it running 24\7 which will probably not be a problem then it can work and will be pretty easy and a lot cheaper. When using a pond pump and a big res of your preffered liquid you have to worry about that not getting too warm if your ambient temp like mine is very high. If your ambient temp is low then it could be very beneficial- gees if I lived in the snow or somewhere where it was cold then I would just have to get a pond pump and a tank outside and run that- too easy and descent temps with no radiator surely.

Well since you've done this before and said it sucked i'll probably just stick to something else, thanks for the input, props for you guys

u might profit from reading this FAQ...its i think quite detailed and explains the fundamentals involved...

As I see it a pond pump can work fine...as long as it is the right kind. A sealed mag drive optional submersible should work fine as they run cool, usually have good head pressure and GPH. Typical inline pumps with large piping (1" to 2" ID's) will be difficult as they are large not to mention noisy...they are basically sump pumps designed to run 24/7. Pumps intended for tiny ponds, say a pump moving 100 GPH then no...that pump will have minimal head pressure and is already moving too little volume. My current pond has a 1200GPH mag drive that would be simply overkill for a PC but it would work fine if I tried. The biggest issues I would have with a pond pump would be size and power. I would want it in my case and running off of 12V...that is why I got a Swiftech MCP655.

All that said, here are some examples:

Good Mag Drive for PC use

Not good Mag Drive (requires submersion)

Insanity (again, submersion)
