I was wondering where the thermal diode/sensor on modern graphics cards is placed. Is it like the cpu sensor on older (?) AMD cpus where it would be below the socket (even tho there isnt a socket, so under the chip) or is it actually on die. The reason I am asking is coz my powercolor x1950 pro supposedly doesnt have temp monitoring (or fan monitoring/control for that matter) capabilities. If it was on die, then I would assume that the video BIOS is just not coded to read from the sensor, so if someone was able to mod the BIOS into reading it, then I would actually be able to monitor temps. I myself have no idea how to mod a BIOS beyond clock speeds tho.
Also, what about the fan speed control? The sapphire x1950 pro uses the same cooler (the non-ultimate version), does it have fan control, or does it run at constant speed? If it does adjust fan speed, then I guess its just powercolors BIOS again.
You got the one with the accelero X2? I have the standard 1-slot cooler, and every program available tells me I dont have any available. Plus my card runs at a constant speed (you can tell as the sound, a jet engine, never changes).
Well it can't be a motherboard because my motherboard isn't that good... a socket 754 MSI. Only thing I can ask is this: Did you replace the fan on it? If so, did you connect the fan's power chord to the video card itself or the motherboard?
I am about 80% sure its the video BIOS. After using the latest RaBiT version and reading from the EEPROM, the Environment monitor was greyed out. After finding a Powercolor BIOS file on the net and opening that, the Environment monitor is accessible. Just dunno if I want to flash the card, since it will void the warranty. Not quite the same as an OC. Plus I dont have a PCI card lying around if it screws up.
