Hi Guys,

Just wanted to know which temp refers to which part of the card. Am trying some trouble shooting with my WC block and this could help me identify areas of low contact:

So what do the following temps correspond to:

1. GPU Temp - This is the main GPU temp of the die, so thats ok
2. GPU Temp #1, #2, #3 - ???
3. Vreg Temp.

If someone could mark it on the pics above it would be great. Thanks.

CoreTemp 1, 2 and 3 are the up itself.

We have shader temp, memory I/O temps, and dispaly I/O(which i think is cache) temp. GPU temps seems to match shader temp.

VRM temp is the VRM on the powerplug side. Where exactly the sensor is, is unknown to me. Some cards ahve a secondary VRM sensor, which is inactive on most cards.
