Review: Nice lcd of temp for my pc compture how hot cpu ... thank u
Review: I'm using it over the air intake of my main PC, to monitor room temperature. It's a nice little add-on so that I know that I'm not really freezing in the winter, it just feels that way. Getting the clip off so as to read in degF was a pain, though. Not much room to reach in, and that little sucker was in there TIGHT! Edit: Bought two more, so I will have one for intake air temperature, one for room temperature, and one for outside air. In the photo, all three probes are taped together. I haven't compared them to a calibrated thermometer, but they all read very close to each other, so it's good so far.
