Do watercooled cases still get pretty hot inside?

[sickcamry]

I am going to get a new case and add an aftermarket watercooled kit pretty soon, but I was wondering how many fans I should use inside it. I want to my system to be as quiet as possible, as I am growing tired of that constant hum sound. (My current case is pretty loud). Does it stay pretty cool inside the case of a system that is being watercooled, or does the internal temperature stay about the same as any other case? If the new case has 6 fan housings, should I use them all? Thanks.

If the radiator is external, they'll be much lower with water cooling. Since most of the heat is taken out in the water and then dispersed @ the radiator, there's not much left inside. You'll have a bit of heat radiating from the CPU itself, but you shouldn't need many (if any) case fans inside the case. Heck, my aircooled setup only uses 2 80mm L1a's @ 7v to keep cool during the winter.

Okay that makes sense, thanks. I will be using a Black Ice Xtreme radiator from Danger Den. Could I somehow mount this outside of the case (possibly attached to the rear)? Thanks.

well you can just shove it on the outside, but when talking external, he was reffering to something more like this

Wow, I definitely don't want to do something like that. Let's say I did attach the radiator vetically to the back of my case. Should by 120mm fan be attached directly to the radiator, and if so, should the air be blowing onto the radiator fins or sucking air away from it? I'm a little confused on how that works.

if your main objective is to get something quiet, then you don't need to watercool at all.
if you're going for extreme overclocking, then by all means go water.
the negatives for water are plenty. i mean if you're in and out of your box 24-7, then okay. but for the rest of us, this should suffice...

1. ONE case with 120mm exhaust/intake and good airflow. slk3700, or anything that resembles it.
2. TWO 120mm fans, (panaflo L1A or whatever it's called comes to mind). use voltage trick take them from 12 to 7 volts. place at front and rear.
3. ONE quiet powersupply 350-400W. anything over is overkill, because you're not watercooling anyway. seasonic, zalman, nexxus brands come to mind.
4. ONE quiet cpu HSF. zalman cnps 7000A-AlCu or SLK900 with 92mm panaflo fan.
5. QUIET harddrives. Seagate Barracuda 7200.7 or the new Samsungs. Both equally quiet. you won't need cooling on these because an slk3700 case or similar will have plenty of airflow. if you want, you can add the zalman passive cooling thing.
6. QUIET vga cooler. Zalman's VGA cooler is most quiet, but the ARCTIC COOLING fan will probably be best since it takes heat out of your case.

all in all, that leaves you with 4-5 fans maximum. 1 exhaust, 1 intake, 1 PSU, 1 cpu/HSF, 1 GPU (if you don't go with the zalman heatpipe.) all virtually inaudible.

P.S. if you've got a northbridge fan, then get rid of that with a zalman northbridge heatsink.
THAT'S IT!!! you've got a really freakin quiet computer. it'll be just as quiet as that water cooling setup in that link i guarantee.
