7970 800 khs on water cooling system !

[sweeppicking]

Hi guys, just coming to show my results with my sapphire 7970 reference cooled by XSPC R7970 water block.


I do it by reading the scrypt readme file from CGminer 2.11.4.
I show this to help the people who has watercooled system, to achieve more performance.
This is my system
I made a lot of changes, already i'm using just 2 7970 reference and using 7970 dual x with air cooling standard.
Sorry for the bad english. thanks for read.

Interesting.  I like the effort but...

$100 for a water block per GPU for an extra 100kH/s not including the pump, reservoir and risk associated with water cooling.

If the cards run about 399.99 each that is an additional 125%  But my hashing power goes from 700 to 800 which is a 14% increase.  It's not worth it unless you can get it up to 900kHs.

Haven't looked into it -- is water cooling quieter?

[anderl]

very much so.

It's definitely not worth it for a dedicated mining rig, but for many of us gamers, watercooling is very nice since the overclocks you can achieve gives a boost to gaming performance as well. Also, you cut down on tons of noise. I can finally sleep in the same room as my rig now.

I've gotten so used to the noise that i tend to get tired when i visit our data center. it's rather soothing.   the. gigabytes aren't a problem.  it's the sapphires that. could keep me awake at nights.

When you have a 6990 with the fan at 100%...it's impossible to sleep. That thing is like 50dB+

Might be worth it to manage heat in the summer if you could put the heat exchanger outside? If I was running a serious farm I would definitely be doing that to save on AC.

If you were running a big farm it would take way too long to install a water block on every card. Also, that $100 doesn't include all the other parts you would need for a watercooling setup: pump, rads, radiator, tubing, fittings, etc.

FrozenCPU.com mentioed delivering preinstalled cards with water coolers.  Of course they would tack on their margin.  So the labor plus profit to them would result in even more expense with little gain.  I expect that after several more card generations water coolers might be viable as percentage gained in hash rate might go up per step of overclock.  personally I would invest in a solid air conditioning unit with proper ventilation.  It would be much cheaper if you have a farm.

Ok i don't make the water cooling system just for mining, i have 5830 cards rig for that, and my personal rig with Water cooling, i made it before know abut Bitcoin and litecoin.
I like so much the hardware and overclokcking, so when i don't play games on my pc, use it for mining.
Just showing a graet performance for the nice hardware fans.

Nice hashing rate. WC sure beats the hell out of fan noise and spreading heat all over the room, slap that radiator at the house window, pump out the heat in the summer.
