well.... i had a mcw60... but changed it out for a ek fc block...These reason why is the ram was giving off a fair bit of heat and i had a 120mm fan on above the vga to dissipate the heat straight out the case...When i got my sound card the 120mm fan had to go... so i swapped out the mcw60 for the ek block...fyi the mcw60 will perform about 5c better than the ek block...and is less restrictive keep that in mind...also with the ram sinks...they should be right...i heated mine up with a hairdryer then stuck them on applied pressure to the ram and let them all sit for 24hours to obtain maximum bondage...

So you can be stuffed making that fan bracket go for the mcw60..if not go the ek block...
