VR-Zone reports that the Intel X38 Express chipset has a heatspeader on it and according to motherboard makers, it runs pretty hot when running dual graphics cards in x16/x16 mode. It runs up to more than 60 degrees in this case and also have rather high power consumption.  However, motherboard makers will be designing fancy heatpipes for this board so there isn't too much a worry about heat. We will be seeing quite a number of X38 boards at Computex and there will be some designs that supports Intel Turbo Memory.
