thanks for reply ibmkg... that is a very interesting experiment you suggested...
this is my 2nd attempt at Water Cooling and on my previous try, i did it in a different way.
this is the setup i made for my brother's almost identical system
where i placed the radiator+fan assembly at the lower front air intake. this sacrificed a HDD cage and works with a regular sized PSU.
the PSU i have needs more clearance and when i tried the original setup as pictured on this thread, the HDD cage feels uncomfortably close to even applying too much pressure on the modular PSU cable sockets.
the way i see it, the only way i can mount a Fan to blow air is to space the radiator from the case about 1/2" but it i fear that i may not have enough room between the CPU block barb to the RAD barb...
... maybe i should have gotten a slimmer radiator?... he he he
as for the fan, the current 120x25mm fan is a stock fan i have laying around, probably stock Lian-Li fan.
if it helps any, i do plan to change the fan to a higher CFM fan... perhaps above 80 CFM-ish...
i did find
this that i am contemplating on buying and installing to provide more airflow in the case...
