Hi, i have a 8x7x2 Heater Core and 4 92mm fans
I just soldered two shrouds for it with 2 fans on each side (suck and blow config) and filter on the front ones that blow air in...
The chambers in shrouds are separated for each fan....
This way the total thickness of a construction is 6 inches...and i have a REALLY tight case...
Also since the HC is 7" wide and fan is only 3 5/8" that leaves alot of room on the sides on the HC (i'm afraid that all air is going to go thru the middle of HC)
I though of putting 4 fans side by side (two rows of 2) sucking air out of back side of HC and a filter on the front side of HC...i know fans are gonna be 7 1/8" but that's OK i'll make a new shroud....
AGAiN the chambers in the shroud will be separated for each fan...
The thickness will be 4" which is better since i have pump right behind HC...
I'll attach a small pic once i get it hosted...
EDIT: It's only 4 fans on one side of HC. NO fans on the other side..so the TOTAL IS 4 fans sucking...just to make clear..
NOW tell me which one is better/more efficient/reasonable...
Please don't tell me to try both cos i did not buy the computer yet
TIA...
