Yeah, it just sounds like room temp + a little heat generated. Nothing to worry about on Idle, they are good temps.
And Corsair Link has a mind of its own... I uninstalled it as its unnecessary, and caused some blue screening now and then. Possibly due to interference with BIOS settings for fan speed, not sure. But icons would go missing too. And firmware updates failed to notify of success, just kept updating till I closed the program down, and then opened again to check firmware version to see if it had worked (guess it did but leaves you with some doubt as to how successful it was). Don't want buggy software on my computer, unless it's absolutely necessary.
Then again, I haven't tried the program for 8 months or so. Might be an update for it. But I don't want to mess with it again.
