There aren a lot of programs that monitor the temps of the cpu and the video cards but there aren't a lot that will do the ram. There are motherboards , mostly Asus that I know will come with a coule of sensor cables that plug into the motherboard and will monitor the temps of what it is attached to.
There are also fan controllers that will come with the same sensor leads and connect to the fan controller and there will be a corresponding fan that can be activated to cool the component.
I just don't know of any free temp software that will monitor the ram temps.http://www.newegg.com/Product/Product.aspx?Item=N82E16835116021
I would get something like this and the ram won't need to be monitored as it won't heat up enough to be a problem with this fan mounted on it. I have used similar ones and they are pretty quiet.
