Already got a fan controller
The trouble with the Thermochill PA120.3 radiator is the space that is required
(Itll take up far less room than 2 x dual rads + hoses), if I install it in the bottom of my case then I will only have room for 1 HDD rack as apposed to 2 HDD Racks with a twin 120mm rad. If I install it in the top of the case then it will interfere with the motherboard and any slots currently being used in the top section of the board.
(put it on the back on a radbox, I did it on a V1000 and it worked fine)
I don't see how it will clutter things with proper cable management and the mass amounts of space you get inside a lian-li V2100 case
(Trust me, 2 x dual rads will use a lot of room), plus the fans that i'll be using are only 14Db so I doubt I will need to use them with my fan controller
(you sure that those fans are powerful enough to effectively blow air through the dual rad?), still, it's there as an option. Can't say i've ever heard of yate loon fans?
(have a look on fleabay, seller called silencio_777 plenty of yate loons available - they are the same as nexus, but without the uk price premium)
I prefer the Apogee GT Block myself, i've heard that the storm ports get blocked easily, that true?
(ive been running an AquaXtreme mp-05 pro le, which also uses the small hose to force the water through for over a year now and it has never blocked up, thats another block to consider, it has arguably as good cooling power as the storm, but with a lower price, if you use clean water and only 5% zerex and flush everything with vinegar every once in a while, it wont get blocked)
Are those DDC Ultra pumps noisy?
(Not used them, but im guessing that 2 of them, coupled with 4 rad fans will be, also consider the vibration, especially in your case) As they are supposed to be quiet, I was originally going to get dual Laing D5-Vario pumps and set them at medium ( for lower noise) but have been told that the DDC Ultra pumps are quieter and perform better.
For your setup, dual pumps, dual rads etc is just a pointless waste of cash
