GPU Tweak WIndows 10 Custom Fan Curve broken

[Ephox]

Hi, my problem is that the fan curve for gputweak in windows 10 is broken. Here is a gif to show what's wrong: http://gyazo.com/8558b595d50163b955327be68a0bfa37

can anyone help? It results in the GPU being 60c idle when it used to be 40c idle with working custom fan curve.

Can anyone help? Really annoying having my gpu 60c idle and 80c temp when gaming when it can be 30-40c idle and 60c 100% load.
