Ok everyone, i switched from my chevette HC to the fedco 2-342 and now my my temps are like 54C idle no overclock, stock volt. On the chevette i had 1 ys-tech fan pulling(it moved some serious air) now on the feco i got 2 enermax adjustables (uc-12fab-b) pulling at max rpm. Oh and i also removed the gpu block. ive been up all night trying to figure this one out, ive tried diffent tubing configurations all ending up with same result. so i went from bigger hc, took out the gpu block now my temps are worse ever. ONLY thing i can thing of is the fact that switched to nozzle 2 on my rbx which has the widest mouth. ??? Think this can do cause so much problems? or are my fans not moving enough air? They really quite but seems to be moving a good amount with the two of them. I am one confused and ****ed dude....any help, any input whatsoever would be greatly appreciated. I was going to build another shroud for to push air in and use the ys fan, but that sob is too loud.
