I am looking to OC the pentium d 805 much like what was done in the article on toms hardware. I have a mid tower case and I have been looking at the complete liquid cooling kits from thermaltake. My problem is this, the big water se may be too underpowered for this sort of an overclock, making the big water 745 perfect. However, the big water 745 has an extra 120mmx240mm radiator that will most likely not fit within my case. What liquid cooling solution should I be looking at?
