First off I'm wondering where I should place a motherboard thermal sensor/probe to measure my video cards temps? I ask because I've placed mine touching the side of the chip and I'm getting temps over 60 degrees. It's a brand new Visiontek Ti200 and that seems kind of high but i hadn't checked what it was before I made some recent changes. The changes involved taking off the heatsink/fan cleaning off the old thermal paste, applying some silver compound and adding the sensor. So my questions are: 1. Where should the sensor go? 2. What are acceptable temps? Thanks P.S. I also tried placing it on the back of the card - the temps got up to 55 degrees in that position!
