Just water blocked my 7990

I have been running the Sapphire 7990 card for a few months now on air for gaming and 24/7 mining when not gaming.

The fans were constantly on at 100% and temps were around the 88 - 92 normal for the card, but loud and hot. Especially in this weather, I had to down clock the cards.

Sick to death of keeping windows open, monitoring the temps throughout the day, I popped over to OC and got the 7990 EK full copper water block. :)

All fitted now, took about 1.5 hours to fit the block, drain and refit the water cooling and now. Even in this weather, full chat both GPU's are under 60 degrees.

Brilliant, silent and wow, 30+ degrees difference and it will also help with gaming :)

My 1st graphics water cooling :)
 
Some piccies

Case needs a good clean and tidying up, but not really fussed about cosmetics, the machine is a workhorse, mining and gaming.

Specs are

3930k O/C to 4.8
32GB 1600 RAM O/C to 1866
Sapphire 7990 water cooled and O/C to 1150, 1700

Currently run 4 monitors, 3 surround for iRacing and a 4th as a Stats / Pit board screen.

A real if not ugly beast :)

BTW, the kink in the piping is sorted :)

2nd card is an older NVidia GeForce 8500 GT for running the 4th screen.

Will test it out for a few days and if all ok, will get it all tidied up and cleaned :)

It has been mining in this heat at full power for an hour now and the max temp on 1 GPU was 59 degrees :) Today before I started and it was cooler in the room, temp was 92 and climbing before I switched it all off :)

I'd try and fix that kink in the GPU-rad stretch of pipe. It looks like you might be able to pull a bit more pipe out the back of the case which should sort it. Otherwise something like this https://www.overclockers.co.uk/showproduct.php?prodid=WC-363-BP&groupid=962&catid=1530

Nice machine!

Thanks mate, just needs a darn good clean and tidy up.

Spotted the kink when I was taking the pictures :) All sorted now.

Might invest in some right angle connectors to tidy it up a bit :)
 
Nice job.
Will send u pics of mine when it arrives, I got the black Nickle block for mine.

Did u manage to over clock it more now its under water?

I reckon a 90 degree connector at the bottom of the gpu would sort that

BTW, is that thin rad really cooling a 2011 cpu and 7990? :)

As I am noticing. Lack of rad space.

Testing and noticing that idle my cpu's are up 10 degrees with the GPU's 100% with mining. I have the CPU at stock for the time being and not O/C to 4.8

Only have a 240 rad for effectively 2 GPU's and CPU !!!!!

For the time being it is ok with mining as the CPU is doing nothing and the 240 is cooling the GPU's

Gaming ???? Well will find out later when I give iRacing a play.

Might have to invest in a new rad, a 360 perhaps.

Not played much with it, will probably do when I get more rad space, which tbh is probably a new case for me too :) Main reason for me was cooling during mining and gaming without the noise of those pesky fans.

My mining now is at 764 kHashes per core for litecoins :) Max temp 61 :)

Your rig will still produce just as much heat as before but the water will make a better job of getting it off the GPUs. Your room will heat up just as much as before but your GPUs will be cooler.
 
Good work. I like the colour of the coolant. :cool: Although water cooling normally interests me very little, this thread has actually made me consider water cooling as an option for my next card. :)

double check its all compatible mate, i dont have that rad myself so dont know how it performs/issues - it just seemed to be the right dimensions

a thick 360 with medium/low fin count with gentle typhoons :)

Will do and thanks

Update : Now mining LiteCoins at 772 khashes/s per core with 62 max temps :)

yeah said that kind of wrong. Now I can keep the door to the office open with windows closed without trying to get the room as cold as possible for air cooling.

House currently is at 26+ degrees in this heat and max I have is low 60's, so kind of worst case situation currently. Now I can keep office door open and heat can spread throughout the house and with the benefit of no fan noises from the card.

Don't have to worry about temps on the card as so low now, fingers crossed for a better solution.

New case and another rad.

All that beautiful gear wrapped up in a bodged together case & loop :(

Splash out a tad more, even if its something like an Elysium or Switch 810 (both will do 360+240 or 420+240).

Once you get enough radiator in the loop you'll be looking around 40c load on both GPU cores.
