Hi,
I have Radeon Pro WX 7100 too (even two radeons).
I was worried about high temps and I felt bad with this.
Yesterday I've decided to replace thermal paste. After this operation I'm shocked.
After 14 minutes of rendering (in Blender) with two monitors connected, temp stays at 67 degrees.
Before it was 85 degrees all the time (with fan at max speed).
I wanted to change thermal paste in second card (93 degrees and I've interrupted render) and again I was shocked. There was vram heatsink missing and plastic started to melt.
I think it was amd supprise for me - that second one was a replacement for previous overheating card.
Now I think that I've sended them good card - I only had to change thermal paste - and they sended me card without vrm heatsink and with unknown past.
