any help is appreciated thanks
cheers,

Ok, generally, using a few smaller capacitors would be better than using one large one (higher surface area for heat dissipation). I'm currently using 3 220uF 35V caps on my Mamba Max Pro. The general rule is to match the capacitance of the ESC with the additional capacitors. The MMP has a total of 660uF capacitance, that are rated for 35V, so you'd want to match this figure with additional capacitors.
As HarlowS says, you need to connect each capacitor IN PARALLEL with the main battery input of the ESC. (IE, +ve to +ve, -ve to -ve).
Disclaimer: If you need a fan to keep your set-up running, then either something is wrong, your set-up isn't great, or something isn't coping. You shouldn't
need any fans, they are installed on ESCs to allow the components to last longer (cooler will mean that the electrical components will last longer), but they shouldn't be required. If you rely on fans, and one fails, something will go.
Plug the fan into the battery port of your Rx if you have a 6V fan. However, other voltage fans may need to go elsewhere. If you could match the voltage of the fan with the input voltage (so a 12V fan for 3S), then you could wire it in parallel with the ESC input wires like the capacitors. The 6V fan would be easier though...
