does anyone know if there is a way to run my fan on the lappy at 100% all the time, im running 70c folding, and id like to be able to cool it down just a bit more.

First of all, start with undervolting if you haven't done it with NHC. You can drop the temps maybe 10°.
Those laptops fills up with dust pretty fast, I'd suggest you take a flashlight and point it to the intake and check the exhausts, take it apart and clean it if necessary. You need a Torx T8.
Apply better thermal paste while you're at it.
I guess you have set the GPU to minimum speed in CCC?
You can set the fan manually with NHC and some extra files found here (http://forum.notebookreview.com/showthread.php?t=98699).
It will only work with older BIOS versions, so you may have to downgrade to an older version. The forum mentions version F.19 as the first one that doesn't work, but maybe newer ones does.
I'm not sure that the fan is built for 24/7 server-like operation, so I'd stay away from 100% if possible and fix the other three things first. You'd be amazed how much they can help.
