Well I'll be changing anyway the 360 is for my gpu loop and 480 for cpu/nb/sb (my first 480 I punctured with screws too long, leaked to hell and back ). I do have another question though, when I run speed fan one of the motherboard sensors shows a constant 63-64 (load or not makes no difference) how can I find out where this sensor is and fix this? I have an ek fc block for my giga ud7, the other 2 sensors report 38 or so.
