If the OP has the ability for side fans they are better as intake, blowing cool air over components and then having fans exhaust thru the rad out the top. Being nowhere near as counter productive.

How thick is your rad? thicker and thinner rads seem to run better with different levels of static pressure. For example, my 30mm 360 rad works better with my Corsair SP120s running around 1100rpm-1500rpm, over and above that it doesn't make any real difference to temps if I pump them all the way up to 2400rpm.

Thanks for the info,

I'm not at home ATM but will reply once I get home and ind the thickness,

Thanks again

Hey sorry to bother again but I just realized that I need to put my rad in the front of tr case frown.gif so would it just be exhaust again?

Thanks

So if the static pressure is not enough, will this cause damage to the rad at all? Or should I wait till my gt's come?

Thanks again
No it wont cause any damage it'll just run at a reduced efficiency and/or somewhat louder. It could be anywhere from 2-5 degrees and a couple dB difference between a non-optimal and an optimal setup, but when you are watercooling its generally assumed you are doing it for the performance and the silence, and thus having the best fans for the setup is a good idea.

For a front mounted rad you can do it 2 ways, 1 - Intake thru the front thru the rad and exhaust out the rear of the case, or 2 - intake thru the back and exhaust out the front thru the rad. One will generally create positive air pressure in your case (being more air pushed in, less sucked out) and the other will give you a negative air pressure (more sucked out than being pushed in)

 

My preference would be intake thru the front exhaust out the rear, and if you have enough room in the front of your case use push/pull with the fans on your rad.

you can do it 1 of 2 ways
intake through rad in front, rear fan exhaust and no fans in the roof
or
intake through the front, intake through the read and no fans in the roof.

the second option has the possibility of pulling warmed air from the roof exits back into the case. since it wouldnt be much air and is only being used to give air to motherboard components, it shouldnt matter at all.

just my opinion.

Hey :-)

 

How did you get on with your rad mounting?

post #18 of 19
I say fans pulling outside air into the rad is what would work best.
But try both ways and see which one works better for you.

Also usually, fans pushing air throught the rad works better than fans pulling from the rad.

So I would have the fans on the case, pushing fresh air into the rad, and into the case.

Hey, I ended up putting the rad on the top and moved my res lower tongue.gif

I might add anothe 360 to the front. Would that be just pulling air into the rad?

Thanks again

But thanks a lot for the help.
