watercooling first-timer - Page 2

post #11 of 19

i wanted this system to be as quiet as possible. i was thinking two 27cfm fans that pulls out all the hot air that builds up in the top of the shroud. decent?

how am i looking compared to air cooling with those same two fans in a push pull config on a heatpipe?

I don't honestly know how that would work on a rad...The BIP would be a good one for that low a cfm maybe....I always use 100+ cfm with 120x38mm fans ...

sorry, those were the 80mm fans. the one im using is 79 CFM

will running two t-lines in a Y config get rid of air pockets faster?

Those would work OK on a GTS I'd go for something like this with a shroud though..The 120x38mm have a higher air pressure and I think they scavenge air through the rad better....


....Panaflo Fan w/ RPM 68.9CFM 30dBA

Or this would be even better...

...Sunon 120mm Ball Bearing Fan w/ 3pin 84CFM 35dBA

...Panaflo FBA12G12M1J 120mm High Speed Fan 86.5CFM 35.5dBA

Seriously you would want to have as much air flowing over your Rad(s) as possible, because that is how the heat is dissipated from the water, if you use fans with less CFM not as much air moves over them... I beleive your best bet would be the 100+CFM fans and if your worried about noise then you can always acoustic dampen your Case, to try and muffle the sound...

um if i need so much airflow for a rad then why am i watercooling? originally i was gonna put some high powered fans on a heatpipe in push/pull, sucking air from the front with a tube. then i was told that watercooling is a good way to get similar temps with less noise. with the added noise of the pump and the two fans now outside the case, it doesn't seem logical to switch to watercooling for less noise unless those two fans are some low powered ones.

so my question is, what watercooling setup will give me the same results as two of these and one of these?

my aim for this computer is to achieve good cooling at low noise and i have a choice between air and water. which will give me a better performance/noise ratio?

In a 24C room... my CPU is 25C idle and 31C loaded. I can barely hear my fans. My HDs are the loudest components by far. So yes, good watercooling can give you great performance with much less noise.
Once again...

Those 79cfm fans you linked will be OK on a GTS 360 or BIP 360....Use them in pull with a shroud....
