watercooling

[KoG]^weaZel · Posted: Sat May 29, 2004 5:32 pm Post subject: watercooling

To answer a question that was posed in another thread I have come to the proper section.

Condensation with watercooling.
Well since you arent dropping below ambient you wont have to worry about it. The only time you would have condensation is if you are using peltiers or phase change units (vaporchill or Prometeia).

The best advice I can give with H2O cooling is dont be in a hurry. Rushing can cost you your system.

Thanks bro,

Are you cooling your cpu as well with watercool?

I'm looking at the swiftech 8600 with an extra 80mm fan and raditor what do you think?

Yes my cpu is water cooled as well as my gpu and chipset. But if I had to do it again I wouldnt watercool the chipset. If you arent doing some extreme overclocking it really isnt needed. The passive cooling works well enough.

And yes Swiftech makes good products. I have tried the 80mm radiators and really didnt care for their performance. At one point I ran two 80mm rad's. Then I tried a dual 80mm and then a single with the dual. Now I run a dual 120mm Black Ice. With this I am finally happy with the temps that I have. In one of my other computers I am using a single black ice and it does good. So I would suggest getting a kit with a 120mm radiator and cool the cpu and gpu.

for an amd based northbridge chipset, watercooling might not be a bad idea. as most of you know, intel chipsets tend to run much cooler

(i guess they aren't working as hard

)

Thank you Jay. I forgot about the chipsets for AMD do run a little warm. I was speaking from what I have seen on my P4 system where I think that watercooling the chipset actually raised the temp. The reason I say this is that at idle the cpu temp is normally 28-30c and the motherboard temp is 29-31c. It usually stays about 1-2 degrees over the cpu until you put a load on it then the cpu does go up about 8 degrees (when playing games) but the motherboard temp stays the same 29-31c.

But as Jay was saying if using an AMD cpu then you would probably be better off watercooling the northbridge. As doing so will help with the overclocking and stability of the system.

how is your hydor L30 pump holding up there? i am going to get a water cooling kit or just grab a bunch of accessories from the shop but i'm not sure if i should do the kit or do it myself.

ideally i'd like to get a fuel pump if it doesn't pull too much current.

Weazy when you suggested a 120mm setup are you refering to a single or dual fan radatior? I might can sqeeze a dual fan setup at the top of my case. The extreme ll is alot thinner than the swiftech radatior so I dont think it would be a problem with space. Plus they have the reservor that fits in the extra floppy drive bay which I really like instead of using up a 5'' bay.

The pumps I am running are the L20's and they are running great. The one thing I have noticed is that the pump I got with my Asetech waterchill kit doesnt create as much flow as the L20 that I got from Frozencpu.com. I believe the difference is in the wiring as the waterchill has a relay assembly that is used where as the other pump plugs directly to 110 volts. (which if you have a psu with an extra outlet that is switched with the psu it is very useful for this purprose.)

Troy,
Either way you go with the radiator dual or single as long as you have a 120mm you should be good. If you go with a dual 120 it just provides that much more cooling capacity. The resevoir size doesnt seem to matter too much. But I do think that if you have a larger amount of water you should be able to keep the temps lower for longer.

If I were to put together a kit today this is the parts that I would use:
Swiftech CPU waterblock MCW6000 $40-43
Swiftech chipset WB MCW20 $37
Swiftech GPU WB MCW50 $38
Danger Den Black Ice Xtreme 120mm Single Radiator $65-85
Hydor L20 pump $35
Tundra Bay Dual bay 3.5" reservoir $29
then you have the tubing and fittings and the tubing to use is Tygon its alot better than the stuff you can get at Home Depot.

I disagree with dubya on the Intel chipset being cooler! I have an Abit IS7 G that is watercooled on the cpu and gpu, and the northbridge has a MicroCool.IT North Pole cooler. The stock Abit cooler was noisy and gave temps around 47C (measured with an independent digital probe)... I swapped it out for a BIG passive cooler from Soyo and temps crept up to 55C. Way too high for me with either cooler.

I was going to go water on the northbridge, but got the North Pole free and now temps are only 33C. That thing is awesome!!

You still need to have proper case ventilation otherwise you are going to cook your other components. I have a feeling that this is the case. You have to remember that there is alot of air being moved by your cpu HSF and if you remove that you also remove that air flow.

^^^^soooooo very true!

so how many pumps do you have right now weaZ? one or 2 L20's and if you know, how much tubing and what diameter do you use? i gotta make sure i get all the info i need as not to have to "pay later"

thanks for all the help again bro!

I run just one pump per computer ( I have two systems already running H2O and a third in the building stage).

With the parts I recommended you use 3/8" ID and 1/2" OD (same thing) tubing. I would also suggest to get extra tubing too what I found is I would get it set up and then want to change something. So it might be cheaper if you got some of the cheap stuff from Home Depot and route all the tubing and see how you like it. Then when you have the design final then install the Tygon.

The next thing is clamps. The best ones to use are the automotive type that you get at a parts store or Home Depot. The only place that you would use the clamps is on the inlet and outlet of the radiator and reservoir. And maybe the pump depending on the fittings that you use there. Which brings me to the pump if you use the L20 or L30 the fittings that are included with the pump are for use with 1/2" ID tubing so you will have to get different fitting for that. I believe that the needed parts can also be purchased at frozencpu.com. If you need or want a parts list with numbers and stuff just email me thru my msn messenger.

Oh I forgot to state the amount of tubing. I would order about 6 to 10 feet. You may have some left over (in fact I think that you will) but like I said earlier it is always better to have more than not enough.

I can not stress this enough do not be in a rush when putting together a watercooling system. TAKE YOUR TIME!!!! water and eletronics dont mix.

Use only distilled water when filling your system. You can use any of the additives for anti-bactria protection.

i got another question for ya. i am about ready to get my watercooling setup and i want to know if it is necessary to have a reservoir in the setup.

It is best to have one.

with a reservoir it makes bleeding the system alot easier. Besides the more fluid you have the long it will take to get to the cpu temp hence cooler temps.

and the larger the radiator the better. Bigger = more surface area. More surface area = greater ability to get rid of the heat that is absorbed by the coolant.

one thing to remember is that different motherboards read the temps differently. SO if you do go to water cooling to record the temps with air and then after the water is installed.

Case in point:
Abit IC7-MAX3 the new bios version 16 was supposed to adjust the temperature reading of the cpu. Well it did, just the opposite of what I thought.
Before the flash the idle temps were 46-48c after the flash 48-50c on air. And this was a p4 2.6c stock clock and voltage. But then when I installed it in my other computer and put the 3.4EE on water the idle temps dropped to 44c at a voltage of 1.625.
