I am not exactly sure of what heatsink compound you are using, or if the silicone pads have been removed and the aluminum transfer pads on the (AMD) CPU. These do provide transfer, but the actual attraction is heat traveling to a cooler surface (tubes).<br /><br /> I have on one occasion found it to be the thermal sensor in the fan itself.

The fan vents are clean, spotless, I've replaced the TIM with AS5 and even tried adding additional copper sinks and another fan and it still overheats! But what is most puzzling of all, is that the air coming out the fan exhaust vent is COLD!<br /><br />So for some reason, the heat is notDrZoidberghttps://www.blogger.com/profile/01575394420252185712noreply@blogger.comtag:blogger.com,1999:blog-3303788613420236381.post-237711743212894252011-02-07T13:01:34.207-05:002011-02-07T13:01:34.207-05:00your theoory is great about reflow of southbridge ...your theoory is great about reflow of southbridge ic.here in my place peoples not know the importance of southbridge.it has same inportance like GPUasifnawazhttps://www.blogger.com/profile/16561699193294468831noreply@blogger.com
