I would give it a try. How it will impact your existing system depends on the temps you are getting at the moment. If you find that your system can't handle it, you can always modify your radiator (or add another perhaps). You may also want to search around Amdmb.com and see if you can determine the amount of heat you will be adding to your system. My bet is that you can handle at least one additonal waterblock provided your setup is currently providing adequate cooling.
