I have a newly acquired athlon xp 2600 mobile chugging along at 2.6 ghz at 1.8 volts on an abit nf7-s 2.0 at 200x13. I have a dtek spiral block with a c-systems CSP 750 pump with a dtek procore heatercore with 2 120mm aluminum evercool fans in a push pull config. I am using arctic silver ceramique paste and a 1:20 mix of zerex racing coolant and distilled water. After getting a stable overclock i ran 100x loop of cpu tests in Sandra with my max temp being 46.5*C (i saved the results to a notepad file) My case temp and room temps have remained the same going from 28-32C case temp idle to load. All of a sudden my pc is idling at 45-48*C and load at like 50*-53*. The waterblock is making good contact(I have checked by pusing up against it and checking temps) and i have not changed anything else in my rig. I will post pics up as soon as I take them. Why would my temps rise so much??????
