Advice about Zalman

[Layzan]

Hi guys, at present my Comp specs are:

AMD Athlon FX-57 Processor
x2 1GB Corsair XMS Pro RAM (total 2 GB)
x2 GeForce 7800 GTX 256 MB (SLI)
Asus A8N32-SLi Deluxe nForce4 Sli x16 Motherboard
Creative Soundblaster Audigy 2

I’m thinking about buying and installing the following fans to lower temps and perhaps aid future over clocks, the parts are:

Zalman CNPS9500-LED Aero Flower
X2 Zalman VF900-CU Quiet Copper VGA Cooler (SY-008-ZA)

The thing is, I’ve never done this before and would really appreciate some advice as I’m concerned that I’ll pay for the parts only to find they don’t fit or something.

I’ve look at the sites and it says that I can use these fans with for example my two GeForce 7800 GTX 256 MB (SLI) cards, but what about slots, space and things like that?

Zalman 9500 fan noise fan is loud when set on high.
With sli plus 2 zalman 900's you will only have space for one pci card.
My advice with an A8N32-SLI is to use a Thermalright SI-120 as the downward aiflow will cool the passive chipset heatsinks as well as the cpu.

I’m not too fussed about noise as my comp is load as it is...

The only other PCI slot I need is for my sound card, I've looked at the set up and under both Graphics cards there is one PCI slot free so I guess I'll be alright.

Ever since a motherboard change from the Premium to the Deluxe my GPU temps have jumped from 70 to 80 during gaming, hence why I want to do something to lower temps.
