Thank you Sav for your update. I am in the process of returning mine to Scan (they've been really helpful) but struggled to find a replacement cooler i could use while i sent the other back as i need my PC. Knowing that the replacement is playing up as well just confirms that there's no point returning for a replacement. So unless there's news of work being done to fix the software and its issues I will most likely buy Corsair gear, replace the TT cooler/fans and return them. More expensive, yes, but you get what you pay for. TT may be reasonably priced but its very clear why, now.
