Best CPU Block - EK Supreme HF vs Swiftech Apogee XT

[Lafas1987]

XT is big block. My Mobo has passive coolling on mosfets and I am afraid that XT not fits.
Do you think that this is not a problem?

About compression fittings now:
As Johnny87au said, i will not have problem with compression fittings as i told above.

Will i have the problem at 3:22 with XT or HF?

Ok, i will go for XT.
More fancy and better mounting.
The bad thing is XT can not mount on sandy bridge...
