Another Rad Question

Yes, as long as they are mounted horizontally and have enough clearance around them. Whether they will provide enough cooling is another matter, which obviously depends on your gear.
 
Cool ok, just wondering mate. Does using fans on a rad reduces temps dramatically?

Also, im guessing that the more thicker and larger the rad is, the more possibility of u being able to use it as a passive cooling rad?
 
I use a PA120.3 without fans in the roof of my case.
Just have a single intake fan (psu is fanless - cpu and gpu in loop)
with all the HOLES in the case blocked up the air is pushed out via the rad.

The air flow is quite low but makes a massive differance over a true passive system.
I run a [email protected] and a 460@ 850/1700/1000

The 460 peaks around 55c in games (31,33,33,40 idle)
and the SB around 58c with all four cores folding (31 idle)

The SR1 rads should be the best for semi passive loops - but any quality thick low fin count rad will be fine.

The bigest issue with removeing the fans from the cpu / gpu cooling is the noise.
With the fan noise gone - you notice the HHD, optical, psu, mouse/keyboard are 'loud' :D

Done the completely fanless thing - and the soft drone of a single fans makes your thermal and accustic life so my easier

Ran my 580 and i5 2500k or i7 930 passively in a 480 sr 1

Some GTs won't make any extra noise and will make a dramatic change to temps. (well not that dramatic, but they'll help)
 
Ran my loop passively without realising after i turned the fans off to clean them and the rad. Played some games for a few hours, temps were pretty good :)

For best results passively you want the rad flat so air can rise through the fins.

how noisy is the GT 1850rpm?

Noticeable whoosh noise.

Got mine Hooke up to a £3 zalman fan mate and it's fine :)

I run my GTs around 600rpm. Have to put my head in the case to hear them. I have 4 of them on 2 240 radiators - so surface area the same as a 480.

I've also ran almost passively for a week when I forgot to turn up my fan controller after cleaning... case fans were doing all the heat extraction.
 
wow cool so i can run my new EX 360 passively and still get decnet temps? lol thats sweet. i am going to swap all my case fans for GT 1850 RPM and turn them way down using a fan controller.

how far can i turn down the GT 1850? down to 650rpm?

maybe. But run your GT's at around 600 rpm
