Radiator + fan placement

post #1 of 2
Thread Starter 
Hi. I am building a new custom pc and i want to make it watercooled. I have never done this before, so i hope i can get a little help with the placement of the radiator and the fans, and the right airflow. The case I have is very small and has only a limited number of ventilation slots. I made some pictures with the options I have. Which one do you think is best?

The parts in the 3 similar pictures are:
Black - case
Grey - Ventilation slots
Red - 3x 40mm fans
Blue - Radiator
Green - Feet for the Radiator so that there is space underneath and i dont have to screw through the top of my case
Arrows - Airflow in/out

The picture to the right is a top view to the inside of the case:
Blue/red star thing - radiator+40mm fans
Big star thing - optional 120mm fans on the bottom of the case
Red thing - optional 60mm fans to the back of the case
Green square - mainboard

If possible i would rather not build in the optional fans, but if you think its necessary, let me know.

The parts i will use is are: i5-4570 or i7-4770 processor, ASRock Z87E-ITX board, 8GB ram, mSata SSD 128GB.




EDIT:
I forgot to mention: The case feet are only 3 mm high (and i dont really want higher ones). Would this even be enough space for a bottom case fan to work appropriately?

The cooling system parts i thought of so far are:
Alphacool NexXxoS XT45 Full Copper 40mm Triple
Alphacool DC-LT Ceramic 12V pump
Alphacool DC-LT Plexi top
Alphacool reservoir individual for DC-LT pumps

havent decided about the CPU block yet.

No. Do the calculation. Area of rad face vs area of supplied air opening.
