Water Cooler for my rig - suggestions/advice?

[L3OUGH]

Hi all,

 

Had my custom rig for nearly two years without having to touch it, however I have had to RMA the MOBO with the company that built my PC due to faulty USB ports.

 

So as I'm going to be having the board out when the replacement comes I thought I'd make the step to water cooling my CPU.

 

I'm a bit of newbie when it comes to cooling, water coolers, positive/negative pressures etc.

 

I've read it's better for gaming rigs to have negative pressure (more exhausts then intakes).

 

Currently have one exhaust, intake and a fan attached to the CPU cooler.. So I have the possibility of two spare if I go for a 120mm water cooled unit. Any suggestions how to set those spare fans up? Use both as exhausts, one as exhausts and one intake etc??

 

I'm looking at getting a Corsair H80i GT. Anyone got any suggestions when it comes to water coolers? Dos or donts? Cooler recommendations etc.

 

Any help would be appreciated.

Thanks

Liam
