ogando_jose , yours is relitivly low because you have a low end graphics card , the more you drive through the chipset the hotter it will get , infact with a single 7800gtx 512 running on one of these boards you cant run a benchmark program without a freeze , they almost instantly hit 80 degs c and freeze.
There is no room for added cooling AT ALL , unless you saw 2 inches off the tail end of your graphics card , but this is obviously not an option.
Thinking of overclocking with this board , think again unless you are prepared for a house fire.
Personally i wouldnt buy one of these boards for any reason at all , they aren't a good answer even in the low end of the sli board range. I am lucky enough to run a place that builds and tests all kinds of new pc's and get to test the good the bad and the ugly , this baby falls into the BAD AND UGLY catigory all at once.
Think of it like this , you have bought a 100 dollar board , expect NO MORE than 100 dollar results , want nice cool stable running with a world of overclocking ability spend 300 and buy a DFI or ASUS sli board.
Another thing to keep in mind , we all know that CPU's , GPU's and Ram modules are rarely the cause of system failure , usually the MoBo packs it in and usually they give no sign of the coming failure and just stop... You guys are getting a BIG sign of nearing failure and ignoring it... if your chipset is hitting 70-80 degrees dont expect to get 6 months out of the board before it fails , because unlike a GPU or CPU the motherboard really cant handle the heat.
