I have been wanting to get into WC for a while, I finally got the chance with my second PC build to do it.

Setup: E6750 and 8800GT MSI P6N Platinum mobo, 2 GB DDR2-800 RAM. Mushkin 550W PSU.

Case is the NZXT LEXA. I really like the case.

Anyways onto the WC part.
I wanted to know if what I am doing will be enough or if I will need to add some more stuff.

Thermaltake P500 Pump.
Koolance CPU300-V10 for an E6750
Swiftech MCW60-R for a 8800 GT.
2 x 80mm dual pass radiators.
Swiftech MCRES Hi-Flow resevoir.

planned setup.

Res>Pump>CPU>GPU>Rad 1>Rad 2.

So Firstly, will the pump alone provide enough pressure and flow in the system to be effective. Second is will 2 x 80mm radiators be enough of a cooling to remove heat from the system. Or should I get a good 120.2 radiator.

Advice please. thanx in advance

Alright, in looking at the kind of setup you are contemplating as an initial cooling loop there are a few things that you might want to consider - the first of which is the pump.

It appears that you are going to go for a cooling loop around 3/8 or 1/4 ID (judging by the pump since it is only capable of using 1/4 or 3/8 ID connectors). The pump itself is not that strong as far as pumps go. It has a flowrate of 500lph (which translates to 132gallons per hour) not very powerful when compared to, say, the Laing D5 or MCP655 (which are the same pump at about $20 more but have a flowrate of 1200lph or 317gph). If you would, consider stepping up to a cooling loop with a 1/2ID (and the MCP655 or 355 pump) - you could still use all the components that you chose.

80mm rads are pretty much a waste as they really don't do a good job of dissipating the heat. To compare, a single 80mm rad may be able to handle 230 KCal/hr (around 930 BTU) whereas a single 120mm rad rates at 790 KCal/hr (around 3100 BTU). Don't worry about the science so much - just look at the numbers. This is a very general comparison mind you but is basically true to scale. So, you are better off going with 120mm rads if possible - otherwise, if you stick with the 80mm rads I would caution against any sort of o'clocking in the slightest.

Excellent CPU waterblock and GPU waterblock and the reservoir is very practical - not too big and can be placed virtually anywhere in a case.

I would definately get a single .2 or .3 radiator, it's less line you have to run, so more pressure.

I don't know what your budget is, but have you thought of getting a D-tek fuzion or swiftech GT/GTX CPU waterblock? their pretty much the top performers atm.

I have the micres micro reservoir, i like it quite a bit, so i could recommend that.

Also, i'd have to recommend the swiftech MCP655 pump. it's an outstanding pump.

Also, are you running 3/8 ID tubes?

If you are going to use 2 radiators, I would place one of them between the water blocks, as such:

res-pump-cpu-rad1-gpu-rad2-res

However, I don't see effective cooling for current processors and gpu's from 2 x 80MM rads. Rather than use the 2 80MM rads, I would definitely spend the extra and get the 120.2 and have the peace of mind that you wouldn't have, otherwise.
