I think the newer EK blocks have pretty good mounting system too like the supremacy LTX but on the older supreme LT it was not that great, as per skinee labs: http://skinneelabs.com/ek-supreme-supreme-lt/3/
That said, even though the LT mounting system is not the greatest, you can still get good mounts with it.. just may take some trial and error to get the correct mounting pressure.
Also important to make sure you are using good thermal paste and the correct amount of it, too little or too much or poorly spread thermal paste can have a big impact on temps. So make sure you know how to look at the contact patch after you remove the block and tell how good your mount was, see martinsliquidlab he has lots of info on that subject
Doesn't matter how much radiator surface you have or how many fans if the block can't get the heat into the water effectively =)
