Hello all. Over the past year or so my CPU temps have been slowly but surely creeping upwards. It has gotten to the point now that using 100% of my CPU for more than about five minutes will cause the machine to shut down. Even with an open case in a 65 degree F room it now idles at about 158 as measured by the CMOS setup utility. I run an AMD Athlon XP 3200+, so I've been using a bus disconnector called S2k Control. This thing is great as it allows Athlon XP chips to achieve sub 90 degree temps in idle. With S2k Control I can get down to about 130 in idle with the case open. When I first built my computer, I had a hard time exceeding 130 even after hours of 100% stress testing. Nothing about the setup has changed since then; the fans are all running at speed, and the heatsink has not been removed and reseated. Also, I am using a Nexus Breeze case and the Nexus AXP-3200 CPU fan/heatsink with Arctic Silver 5 thermal compound. The bottom mounted 120 mm fan and the CPU fan have been speed limited with resistors. I can hear it now. "Oh, there you go... take off the resistors!" I will probably do this soon, but the fact remains that the same setup used to work perfectly. That means there is another underlying problem, and this is my question. Can a CPU go bad?
