NOT GOOD FOR INTEL LGA1700

by Richard star_border star_border star_border star star

At first this looked great and well made in all respects. Bought it for my lga1700 motherboard yet wish I hadn't. It was a little tricky to sort out the various parts to suit my lga1700 but the real fun came when I tried to fit it to my processor. IT HITS THE TOP VRM HEATSINK !, took some right fiddling to get it to sit flush and tight on the processor. Then came the fan fitting, THE FAN COVERS THE FIRST DIMM SLOT AND PRESSES AGAINST A CARD IN THE SECOND !!. I had to remove the fan mount rubber strips to get the fan away from the dimm in the second slot !, hence the fan is not tight against the heatsink now and it would be impossible to fit 4 memory cards in the future. The fan sits just below the hight of the memory cards making the first slot unusable !!!. Not impressed. BEWARE IF BUYING FOR INTEL LGA1700
