Back to finish, I hope soon ! Im headed to take back my magnumxxxl 8 inch to trade for the 6 inchers this morning. The 8s didnt give me enough room to hook up venting. I went to by 6s but was talked into 8s flowing so much more, long story short, 600 hps wont use that much cooling, I believe. Finally have the money, feel better(3 weeks sick), & the time to button this baby up !
