[Solved] CM690 + Megahalems + top fans = fit?!

Well, I am installing a Prolimatech Megahalems (Megatron if you will) on a CM690.
I do know they fit, but I want to know if I can also fit the top fans on the case or if the heatsink will block them. I am installing it as recommended by the manufacturer (fan blowing from right to left, towards the back exhaust fan).
So, anybody else has CM690 case with Megahalems and could confirm this for me, please?

Cheers

I have the Antec 1200 case and asked Prolimatech tech support which way to install the Prolimatech Shadow (same thing, different metal finish). My PC assembly bench (aka dining room table) was covered with parts and fearing the wrath of "she who must be obeyed" we started the build before Prolima folks had answered thinking logically that as heat rises, should install w/ fans blowing up.

Latter that day, e-mail arrived from Prolima saying that their testing has shown best performance with HS fans blowing towards the rear of the case. My guess is, this gives 2 way cooling with fans blowing to back and natural convection, combined w/ top fan taking cross ventilation in the other direction.

Didn't change it but if we decide to pull off the MoBo heatsinks off replace the thermal compound, will do it then.

Thanks for the ideas guys!

I've installed it yesterday night, and it fitted very well!
Its in push-pull config. with two medium grade fans (XLF 1255, 1500rpm, 61cfm, 20dB) pointing to the rear, where I have a Coolermaster R4 fan (2000rpm, 90cfm, 19dB). Working great!
With both fans controlled by the motherboard (installed them together on the cpu fan header with a "Y cable" for pwm fans from Gelid) at about 1000rpm the cpu is idling on 36 celsius (@ stock freq.) and 55 on prime95 torture tests!
That piece of s*** that intel ships the i7 with was doing 44 celsius on the same conditions and if tried prime95 it always went above 80 forcing me to stop.

Megahalems are really good!

As for the whole case configuration: i have 3 coolermasters 12mm, 2 as intake from the bottom and front, and 1 as exhaust from the top/rear; and that Coolermaster R4 blowing loads from the back (exhaust). No side fans, but dust filters on the side openings and intakes. All the exhausts and the cpu dual fans are motherboard-controlled, and the intakes work at full spin strait from the psu.

Working great!
