I recently upgraded my PC to have a Ryzen 9 5900X, an EVGA RTX 3080 Ti FTW3, and 32GB of Trident Z Royal RGB RAM all on an MSi B550M Mortar Wi-Fi placed in a Corsair Crystal 280x case. My 5900X is being cooled by a Top-Mounted H115i Elite Capellix & My fan config at the moment is 2 LL120 fans in the front for intake, 2x SP120 Elite fans on the bottom for intake, and 2x ML140 Elite fans on the top for exhaust. This seems good on paper, however my CPU Idles at 45-50 Degrees Celsius & if I do so much as open an application (even something light like the file explorer), it causes my CPU to spike up to a little over 60 degrees instantly. I have checked that I have applied enough thermal paste & mounted the cooler properly, and I indeed have done It right. How do I fix my thermals in this case? (Numbered list shows more questions related to my main question) 1. What settings should I apply in the BIOS/UEFI? 2. What Fan Curves should I use? 3. Should I make any modifications to my case? (Raising the feet, replacing the top panel, removing the dust filter, etc...)

Brand new build. Issue where the USB devices keep disconnecting for 4-5 seconds every 5 min or so making it unusable! Also in iCUE 4 the Commander Pro fan hub, keyboard, mouse, AIO, RAM, lighting strips are all detected but the lighting node core which controls the RGB for the fans is NOT detected. Used 2 separate lighting node core's issue persists. Its plugged into known good USB and SATA power, nothing.
