what temps do you guys get with water cooling?

[h2sammo]

i just installed my water cooling and i am around 35 celsius, when the CPU isnt under heavy load. this is very close to what i used to have before. the advantage comes in when i put the cpu to work and it gets heated up more. the specific heat of water is pretty high and it can eat a lot of heat away from the processor. even though i am aware of this physics stuff, i still expected the temps to be a bit lower.

i dont use distilled water, just regular, and i have a radiator, but there is no fan blowing on it, so i dont know if its of much use right now.

i am thinking that maybe i dont have good enough contact with the processor die. I put premium arctic silver on it, but i am kinda afraid to tighten the waterblock screws too much. The waterblock is kinda heavy after all. Do you guys tighten it hard?

I think i should get lower temps with this Duron. I mean from what i know, it shouldnt put out too much heat, should it?

thsnk you

i run a Duron @856
on a ABIT KT7A
512 sdram
geforce gts 32 megs

Posted in your other thread, but 35 is a good temp - especially without a fan. You need to watch your load temps however. Without a fan your radiator may never be able to get rid of the heat, and your temps would keep increasing. At idle, good heatsinks can come close to cooling a cpu as well as a watercooler. A watercooler earns it keep when the cpu is under load, and when you are running 2 volts through your cpu.

You should really put a fan on that radiator. I'm surprised your running at 35C, at least after the water's had a chance to heat up. I have two 120mm Ultra-clears blowing through a 12" radiator and I get 32C idle and 40C at load. The real benefit to me is the sound. My computer is in my bedroom, and that "delta screamah" used to make falling asleep hard.

if 35c is full load temp that sounds very good to me for a duron . also depending on your room temp decides if you need a fan. personelly i would use distilled water and some water wetter to prevent gunk from happening in your system. as far as how tight to tighten a block watch your temps when you first start up if they dont level out then you dont have it tight enough. since i use dangerden waterblocks for amd i usually tighten the waterblock evenually till all the springs are compressed. remember you have to be very carefull doing this

yeah,

i tightened the springs until they were compressed all the way, and that helpes the temp maybe 1 celsius or two (i think).
as far as temps go, if i turn the computer off over night (water cools down), then idel temp will be 30 for the day to come. If i leave computer on over night, idle temp will be 32-35 for the day to come.

when under 'full' load, temps get to 45 adn 49 respectively. never git higher than that.

and this is without a fan with a cube radiator from danher den. as i posted on some other board, when i open the dor of the drawer i keep the radiator and pump and water in, temps drop about 2-3 celsius, thats how efective this radiator is. i will prob put a fan on it when it gets hotter in here, and i am sure i will get much better temps with a fan. this small radiator makes much more of a job than i expected.

im in Tallahassee, FL, so its like, hmm, 70-75 F in my appt.

These guys have already said it, but I'm going to re-emphasize it: you NEED a fan on the rad

It really makes a difference.
