Hey guys, a PSA. So I had to bail on FSO last week after the second PC crash of the night just as I took off. Upon further review I saw that none of my case fans were turning and I was getting 39c out the top of my case (ouch!) according to another remote thermometer. Took me a while to figure out what was happening but I found that iCue, which I use to control all my LEDs and fans on this PC, had decided at some point to stop adjusting the case fan speeds when I had it pointed at any of my GPU temp sensors. This is how I've had it set up forever without issue. I could run a manual profile and the fans would spin right up. Good news as it showed they weren't all dead, or the commander pro they're all plugged into. Pick pretty much any other sensor and they'd run. Put them back to the GPU and they'd just stop. It didn't affect the AIO at all so good news for my CPU. Those fans kept running. The fans actually on the GPU were spinning 100% but what it had to work with was just a little toasty with no other airflow so it shut down.
Turns out-- I'm not alone seeing this. It's a bug introduced with a recent update of iCue. Corsair is aware of it and is working on a fix. Meanwhile, I'd use another sensor in iCue if you're running custom fan curves. I switched to one of the thermistors that came with the commander pro monitoring case temperature directly and that works, just not as fast. GPU temp will rise faster than the actual case temp. Alternatively, you can switch back to iCue v4 (which is a chore) but you'll have to reset everything if you do.
Those pesky updates! They fix all kinds of stuff! LOL
