We wanted to attempted to test the SI-120 in as close as setting as possible to what they were when we tested the XP-120, the only slight difference are the case which is a different brand but they both have 120mm fans at the rear so that’s close enough. The video card is another issue, the XP-120 was tested with an X600 Pro video and this time we will be using an X800GT video card so there might be a degree or two of heat difference, but being that the video card is an HIS IceQ II I really don’t think the card will give off any measurable heat to worry about.
