Looking for Fan Control Utility for Acer V5-171

I'm looking for the fan control utility for acer v5-171 model like 1810tray...
I've been trying a lot of other things like acfancontrol, a1ctl_v1.0, speedfan, etc... but there is not a single one working.
In acfancontrol 0.72 case, I tried to changed setting value so many times but it doesn't work.
Is there any mistake?
Actually I think the default bios fan controlling is not so bad... but there is two faults.
The 1st thing is that
it never stop its fan once it starts to work fan controlling (at the first time, the fan doesn't work for a while until the CPU sensor is 45 celsius).

The 2nd thing is that
the time to work fan is 45 celsius... I think it's early time a little bit.
In 1810Tray case, it's 50 celsius.

I've been using Aspire 1810T model for 3 years using 1810Tray so I know its perfect fan controlling performance.
I'm expecting that perfect performance...
Please help me and Let me know any other tips for this issue... I'm trying for 7 days already...T_T

 

My solution : keep using your acer 1810T; with windows 8, 1810 tray, 4 GB of ram and a SSD, he's still amazing including autonomy.

 

I'm already using in that way... 4GB of ram and with a SSD... with 1810tray on my 1810T
Anyway thank you for your reply
