Anyone knows what thermal compound that is that comes with the stock hsf of the i3 SB series?

If I changed that to Tuniq TX-2 or TX-4, worth it ba? I'm not after the idle temps, more like the loaded temps during hot days and gaming, kinsay naka try na and results?

Also the thermal compound being used by Inno3d for the gtx 560ti (stock 560ti with the 560 cooler, the one with a signle 80 or 90mm fan(didn't measure) that can go 5k rpm), anyone know what this is? Wala gyud ko kita info sa net about inno3d products being disected, since the brand rarely reaches the west except for thier Ichill series.
