err.. well yeah brad no wonder your getting ambient water temps
besically im getting a heatercore style rad on my watercooling system (planning to build it around may-june) but just cant decide whether to get a chevette kind for 1 120mm fan or something else that can fit 2 120mm fans.. kinda effects where i wil mount it - with the bigger one would mount on the top of the case, moving the psu somewhere else maybe to the front under the hard drive, with the smaller one i would move the hard drive and put the heatercore under the floppy. could also get two of the smaller rads and run them in parallel but i think thats kinda unneccesary and could get kinda expensive....
