My Radeon 9700 videocard has a Zalman heatpipe with the separate fan on it. I placed a temp sensor from my aerogate II near the gpu of the card and its just sitting by card laying on the heatsink on the bottom. The sensor is reading 40C when not under load and I have the case door off. This seems a high, any suggestions on how I can improve the cooling? Or is having the temp sensor lying on the lower half of the heatsink sandwhich a poor reading?
