Water Cooling!

Hey guys,

I know there are a good portion of you out there that are into gaming and computers. I was wondering if anyone had any experience with watercooling. Specifically GPU water cooling?

I have acquired a ThermalTake watercooling bundle off a member here, and would like to know.... If I remove the stock CPU water block, and replace it with a GPU water block would this have enough cooling power?

The GPU this is going to be used on, is a HD 5970.
The intended GPU water block is here... http://www.clunk.org.uk/images/articles/water-cooling-news/EK Guide/contents.jpg (EK FC 5970 Water Block)
The GPU puts out 400W of heat stock.... I intend to OC it so I would assume 500-600W would be max after OCing it.

Lastly here is the item.



Approx measurements are L x H x W ( inch) : 4.34" x 1.2" x3.38" (just the radiator)

Thanks guys!

Bump?

Water cooling will ovbiously have more cooling power over air so I dont see why not

Is there any way to test the cooling capabilites of you water block without connecting it to your computer?

That's what I'm asking.... :thinking:

If you only use it on your gpu it should most like be enough, but it all rests on the condition of the cooler, since its second hand item it might not do the full 100%anymore

Also a tip if your going to use it....give it a good test before you instal it, and get some new tubes, some of those wear down after a long time used and might tear at the ends and you dont want that to happen

When you installed it dont OC all the way yet, do it in stages over a few days just to make sure everything is alright

Oh and iirc this set was also used for older cpu's which get pretty hot to, so if it was enough for those old cpu's it should be good enough for a gpu

Well I got time today to play around with the kit....

Seems it hasn't been used in years...





I have flushed all I can out of it and filled the reservoir and started the unit...... nothing. There is no flow at all. I am pretty sure the pump is running... so there must be a blockage inside the radiator. I will try again later to flush out the blockage with water or something.

I will update you when I have done more!

Could you not put one of those ceramic block resistors flush against the radiator and supply it with a constant current then measure the resistance across it with the water off and on? Then start doing some sums, Ohm's law, work out the power absorbed by the water cooler in a predetermined time preiod?

I don't think heat dissipation and electrical resistance are linear or correlates to radiator dissipation power. There is a formula To work it out, but exact water flow is needed as well as accurate temp before and after the radiator, ambient temp and cubic foot per min rating on the fan. That's a lot of variables which if calculated incorrectly will give a very skewed result.

From my research... they are estimated at about 250-300W cooling power stock. You can upgrade parts in order to further increase the cooling power... but that's not exactly worth it if you are just messing around for fun / experimentation.

have you tried to unhook the pump from the radiator and run the pump with its inlet hose in some water? just to be 100% sure the pump is actually pumping
i once had a pump which was running but not pumping...its little axle snapped inside...

but it would most likely be crap or dust in the radiator tubings, you could try to insert hot water with a little vinegar ( little bit acid ) in it and shake it a bit.

after that flushing it with clean water to get everything out of it.

After this you should have a nicely cleaned radiator

i hope it works out for you :beer: good luck!

:bumpit:

any progress so far?

kinda curious, always interesting these kind of things
