Thanks for checking into this Mike. I'll keep an eye out for any updates. -Tony

Thanks for your response. I removed the TT RGB Plus software, flushed the AppData, and re-installed the latest version as you suggested. I also fixed the warning on controller 2 (It was actually one of your other posts that showed me how to resolve that, so kudos). Unfortunately, the problem still persists. Another thing I've noticed is that the Tctl & Tdie displays are different in the TT HWiINFO window between the 1950 and 2990. Here's the latest TT RGB Plush display (still showing 0-deg C) and here are the TT HWiNFO windows for the 1950 and 2990: On the 2990 the temp readings for the CPU show up as Tctl/Tdie instead of two separate values. They show up correctly in the HWiNFO app, so it still seems like maybe the TT RGB Plus software needs and update of their HWiNFO SDK.

I'm in the same boat. I have a Floe Riing 360 on an older 1950x workstation that I've been using for the last few months without issue. I use the thermal fan coloring profile so that I get a visual cue when the processor is under load. This weekend I built a 2990wx workstation with a very similar setup and now I'm also getting a flat 0-deg C reading from the TT software. The cooler, however, seems to be working correctly since I’m getting peak processor temperatures just a few degress above the 1950x (as shown with HWiNFO). TT Readings HWiNFO Readings I would like to leverage the thermal coloring profile with the 2990wx machine like I do with the 1950x. Does the TT software just need an updated version of the HWiNFO SDK, or is there another update required on the client end? Thanks, -Tony
