I have four identical GPUs on a system (not crossfired). One is too hot, the other three are ok. I want to use Tthrottle to slow down Boinc on the hot one only. But Tthrottle only detects one temperature. When I connect it to GPU-Z, it detects four identical temperatures (even though within GPU-Z there are 4 different ones). It can't see HWInfo for some reason. How do I throttle one card?
Step one on the External tab: GPUZ (checked) you should select 4 different GPUs.
There is a description to run HWiNFO as well.

I checked all 4, but they all read the same temperature. Somehow Tthrottle was reading the same sensor from GPU-Z 4 times.
It didn't see HWInfo at all. And I don't like this: "HWiNFO, when using the installer, the 64 bit version stops working after 12 hours."
I've taken the easy way out, I just lowered the clock speed for the offending GPU.
Can't you set the fan profile for that card?
The fans are at 100% from the profile I put on it and it still goes to about 85C and crashes the machine. It's the original fans, they're working fine, but a huge amount of piping hot worryingly smelly air blasts out of it. It's in pretty spacious air in a 25C room. It does receive a bit of hot air from a nearby GPU, but not much. Not sure why it's so hot. It seems happy at 2/3rds clock and is now sitting just below 80C.
