I have the Swiftech Apex 120 kit with a mcw55 vga block, system specs are in my sig. On my old system (XP 2700+, no vga block), I barely got above 40C at load with the fans on the rad at 7v. Now, I have the fans at full blast and I'm hitting 53C at load. Does my x2 and 7800gt really dump that much more heat into the loop? I was planning on overclocking both the x2 and the 7800 (I may still do the 7800, it's only like 31C at load) but with the temps that high, it seems like a bad idea. Any suggestions?
