[Hi BOb]

They accualty help my video card RAM stay cool a normal heatstink would blow on them however I got a modded zalman one witch blows very poorly on the RAM and it would over heat with the fans it helps cool them also it helps my Southchip witch gets to around 100C without a fan on it *poorly made maybe?* suckers get really hot when you overclock them same with my northchip when I overclocked my quad cpu to 3.5 ghz the temps whent from 50c to almost 100c! withc in crazy hot so as you would think I added fans ALL over the place shockly enough all the fans are very very quite can't hearly hear my computer! freakn in love with this computer and yes this camera takes WOUNDERFUL pics I wouldn't highly recomend this Cammera Fuji S7000 look it up you'll not be sorry!
