I have a Vaio Flip 15 and I am desperado about it's fan noise. Even after the Vaio full updates (including last BIOS version), even after Win 8.1 update, even after all drivers updates, even after setting power plan to silent... the fan is completely annoying! It starts for no particular reason, even if I am not doing multitasking, even if the laptop has just no activity. It can run for 20 mins at a high level of noise then stop. It can start and run at relanti with a soft noise (still annoying) or, if I start some little game, it can boost up, like a machine from hell. Please let me know if there is any solution for this! Vaio Flip is a wonderful laptop, with super-features, but this fan problem is so annoying! I am seriously thinking to return it, even if I wouldn't like that. Still, I am searching for a solution. But I'm out of ideas for now. There are tons of similar problems with the Flips, maybe you found something that works, guys! Thanks.
