Fans on your waterblock?

I would just like some opinions from people with watercooled systems. I'm just sick of all the noise from these fans and the noise they produce. I've heard that some people dont use fans in thier watercooling systems and was wondering if thats alright? If they can cool the cpu (nothing extreme) without fans I'm definately going to look into getting one.

I've heard that a fan is a good idea if anything fails in the water-cooling system, such as a pump failure.

i run my water cooling with no fan at all. just water block, water tank, water (drinking water, not even distilled) and a fanless radiator

not even a case fan.

the only fan in there is the fan on the mobo chips and video card, and i dont thin anybody would be annoyed by those tiny ones.

cooling works fine, pumped never failed since i started using it.

temps rarely higher than 43 celsius, ~30 when computer is idle.

im cooling a Duron @856

I'm cooling a Thunderbird 850 overclocked to 950 with nothing but a cheap pump, a waterblock, and a 5 gallon bucket of water. Only fan is the power supply fan. The case cover is also off. I don't think I can run the chip at 100% for more than about 10 hours because the water temp slowly rises. Turning it off overnight lets the water cool back to room temp.

However, my cheap pump makes slightly more noise than the quiet 80mm fan I had before on the heatsink. I'll probably switch back, and improve my water cooling setup for when I upgrade to 1.5 ghz +

Thanx for the replys. From the looks of it, it seems that a fan wont be necessary.. considering i'm not doing an extreme oerclocking. It would be great to have silence again. =]

same as me NAC
my water also sowly gets hotter. but chech this out:

as i said, i have a radiator, its inside a drawer, next to the case (my case cover is also off, just have a towel on top of it to cover the water lines ( i have cats you know).
when i keep the drawer closed, the water gets hotter during the day. (cpu temp hits ~35 when idle)
one day i said...hmm, let me open the drawer as long as i am next to the computer, playing or writing labs...using it.
and guess what, the water temp cooled down in about 10 min. i can feel it with my finger. it cools down in 10 mins. thats how good and useful the radiator is. it cools the water in 10 mins, dramatically, so i can feel it with my finger, and it has no fan on it, just the air it comes in contatct with when i open the drawer.
ican imagine much better results when i put a fan on it

if i could only find a way to keep my cats away from the water lines, or drinking the wetted water from the reservoir, i would keep the drawer door open at all times.

bythe way, under heavy usage, (3D games and some other applications on) my temp never went above 45 celsius.
before, with a fan, i would go to 60 celsius
now this is a good improvement
i am so curious how good it will be when i figure how to put a fan on the radiator, considering its out of the case.

NAC, you should "upgrade" from a 5 gallon bucket to a metal 5 gallon bucket.............:) Seriously though, if it was a metal 5 gallon bucket you could blow a fan on it for improved cooling. Or if your pump can handle it, bury it in the ground outside your house and let the ground passively cool the bucket an therefor the water. But I think simply putting 20+ feet of buried copper pipe would be a fantastic passive radiator and if you have power outside you could even put the pump outside.

Only problem would be if you live in a cold climate you might have to cover your pipes that come in the house to prevent condensation. Might have to do the complete protection if your outside temp gets too cold.

You don't need a fan on your wb. There is a very small chance your pump will break down. Those things are aquarium pumps. They are made to last for years with constant non-stop use. I never even bother to unplug my pump even on the rare ocassions that I do turn off my computer.(SETI@Home:D running here)
