I had a BSOD on my PC a few days ago. I thought I would check out temperatures etc using systool just in case something might be too hot due to a fan not running. The hottest thing in my PC (this is when running in 3d) is the Voltage Regulator temp on my X1900XTX. The highest I've seen it is 62 C. Should I worry about it? Everything else is cooler and seems OK to me. I have an accelero x2 cooler fitted to the card.
