I have not replaced the fans and the microfan isnt working either, noticed it today by pure luck.
Did a firmeware update and it spun up for while reinstalling version 0205.
After the installation microfan returned to twitching, every 5 seconds or so.
Ã‚* I havenÃ¢â‚¬â„¢t noticed my micro fan not working and I have all the AC updates too. I will double check my own rig later tonight.
Have you tried a custom speed setting? Ã‚*I run my own fan curve on that fan. The drop down menu choice is still there?Ã‚*
Update has being push now. Please check.
I run a small test and the update put the mini fan to work again.
I will make some checkup and report back later But the update fix it.
If update arrive installed it and restart the pc. but it works now perfect
