Is your mobo an Intel mobo with a supported hardware monitoring chip? If not, the temps may not be accurate. IF so: 46 is 115°F, that's about the limit that I would be comfortable with for a CPU. But something's wrong if your MOBO is showing 118°+, and something is much more seriously wrong if the other temps are 68 (154°) and 81 (177°)!! Feel all the components on the mobo yourself and see how hot they feel. Try another HW monitoring program like MBM5 or SpeedFan, but like any other your HW monitoring chip must be supported. http://majorgeeks.com/download.php?det=311 http://download.cnet.com/Motherboard-Monitor/3000-2086_4-10518386.html http://www.dvhardware.net/modules.php?name=Content&pa=showpage&pid=3 http://www.almico.com/speedfan.php http://download.cnet.com/SpeedFan/3000-2094_4-10067444.html There's also benchmarking software like SANDRA and AIDA32 (now only available as "Everest" I believe) that will show you temps. If you finally determine those temps ARE accurate, SHUT OFF YOUR PC. Something is wrong. Use those programs to see if all your voltages are in spec (3.3, 5, and 12v). If any are really high, that MIGHT be the cause. But you should NOT let the PC run at those temps. Even if you put fans on the hot spots, that does not fix the problem of why they are so high. -Clint God Bless, Clint Hamilton, Owner www.OrpheusComputing.com www.ComputersCustomBuilt.com www.OrpheusComputing.com/cheap_reliable_web_hosting.html www.OrpheusComputing.com/PCworks-computer-help-email-list.html ----- Original Message ----- From: "Dale E. Heltzer" According to my Intel Desktop Utilities, the processor and motherboard are at 46 & 48 DG C respectively. The I/O Controller Hub is 81 DG c, and the Memory Controller Hub is at 68 DG C. I wonder if the latter two readings are cause for concern? Remedies? TIA --- Dale E.
