Arthur, I picked up one of these Radio Shack IR thermometers when the internal sensor stopped working: http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&category%5Fname=CT LG%5F011%5F008%5F003%5F000&product%5Fid=22%2D325 I've been very happy with it. I can point it into the vent towards the graphic card or down into the core and get reasonable readings. It's allowed me to monitor my Cube for problems. You may be able to find a less-expensive model. Fred On 9/8/05 10:43 AM, "Arthur Busbey" <a.busbey at tcu.edu> wrote: > Thanks for the responses.
