I recently bought a kit from danger den with the the highest rated eheim pump, maze 4 cpu, 1/2" ID hosing and a heatercore for the radiator. My system is an Epox 8RDA3+, Athlon xp2100 Tbred running 12x200@2400, 3200 corsair ram with the water cooling rig. The temperatures seem to be way high averaging around a 100f when case is only at around 78f. I've tried reseating the block about 6 times different pastes all giving the same results in temperature. Im starting to wonder if teh radiator isn't cooling well because when the fan is off the temperature doesn't rise at idle. my brother's system is also watercooled but with a maze4 and 1/4" ID hosing and hes only about 4f off his ambient temperature at 78F/82F. I was wondering if anyone has any ideas or suggestions this thing is running way too hot for what it is. thank you
