This has been bugging me for the past month. Using the "upgraded" heatsink I got with my 1.333 Ghz cpu and a7v-133 motherboard, the temp reading with asus probe sometimes reached as high as 69C. That was fixed by employing a box fan, and buying some cheap termal grease. Still, asus probe was reporting up to 62C. I also tried a chrome orb which produced similar temps to the stock heatsink. I went to 2cooltek.com and ordered a Thermaltake SK6 with a delta fan. I also got some nice artic silver II grease. so I put my computer together, making sure I followed the directions on articsilver.com and everything, and I load up ASUS Probe. The temperature is still at 57C idle. 60C under load. Needless to say I was rather pissed. I went to download.com and downloaded a generic cpu sensor program called Hmonitor. the cpu temp now reads 50C under load. Any ideas what is going on? I'm still not done with my case mods, so I think I can probably lower the temp a couple more degrees, but 60C is way too hot.
