Well I've been looking.
The arctic RL needs 88mm of clearance... And at first glance, the maximum I have is 70mm....
I'll have to check the size of the others
Edited... I've got an idea... let's see if I'm not wrong...

If you look at the image to see if I'm saying it right. Where now there are two fans, there are 7 cm to the metal box where the power supply and the disks are...
The arctic has a 38mm wide radiator and a 25mm fan.
If I put some fans outside the box (but covered by plastic) inside the tower would be the radiator and 1 fan... 25+38 = 63 mm, and I leave the other fan outside the box...
The same thing happens to me above, but the distance is less, only 6cm... so it wouldn't work either...
I'm going to see how the arctic is installed
EDITED2....
Well... everything is on youtube
... and here's what I wanted to tell you...
