Maximum PC

Just picked up another GTX470 to link with my other one. Question is will they fold as one card or will each one get its own WU? Or should I do something different?

Can't wait for this heat to let up it is going to be 110+ until next weekend. Won't have them folding for another month or so, needs to get under 70 at night before I do that...

Has anyone used something like this to cool cpu, gpu before?

Thanks for the help.

Can't field your folding question, but I have used TEC's in custom builds before.

Thermoelectric coolers are more efficient than air and liquid cooling, and less when compared to phase change or liquid nitrogen cooling. A TEC will keep your chips tip top, but depending on the design it can also add to the ambient temps in your case since when current is added, one side of the plate will get just as hot as the other side gets cool.

The TEC designs that are most efficient for cooling a home build would be found on websites serving computer builders i.e. performance-pcs.com or crazypc.com.

Fold with them as two separate cards. SLI or not dosnt matter. Never used anything like that to cool mine but have them under water.

sli 470's.

feeling hot hot hot...


on a more serious note, you need to configure them as 2 separate units, with one client per card with the -gpu 0 and -gpu 1 flags, and give each a different machine id.

Thanks for the info.....

feeling hot hot hot... is that a issue? or are you trying to tell me something?

Uh I believe thats part of a song lol. They do get warm though as im sure you have noticed even with your single 470.

Hot is a true statement for sure thought maybe there was more to it other then a song. I guess if there was he would of said so. Anyway that was kinda my second question but all is good.

It's still hot as HELL here.

Got my other GTX470 today installed and is folding. They are running about 5 degree difference not sure if that means anything. Have not hooked them up to play games yet but folding is not a issue. Looking at 32,000 PPD if I keep them running with my CPU (i5). Does that sound about right?

Thanks for all the help.

So you mean 32k with you CPU? If so then that sounds about right.

Roger that my CPU is folding too. Now I seriously need to look at cooling. I wont be able to keep this up right now with the outside temps still in 100+ range. But it will be a nice space heater for the few months out of the year that we get into the 20's for the low.

Have you cranked up the fan speeds on your GPU's for the short term?

Yes had both fans blowing just for one WU for now. The fans are really loud and it's still to hot. I have been looking at other types of cooling water, or cool plates.
Thanks for the info.

I love my water cooling set up. Keeps them much cooler and MUCH quieter.

Do you have a price range? Danger Den makes a pretty decent block for your cards...

If I was in your situation, I'd identify the blocks you want first, then the barbs. That will dictate the gauge of the tubing you'll use. Once you have those parts in place, you can start identifying where you have room in your case for a radiator. The temptation for me would be to use an extended radiator with quieter fans externally (maybe via an adapter off the rear 120mm fan port?), rather than something smaller internally that would require louder fans to move the same amount of air. Depending on where you would have mounted radiator(s), this may leave you with more space for a reservoir also. The pump is usually the last part I spec simply because having the rest of the loop in place lets me know what kind of flow rate I should be shopping for, and where I'll have room to mount it.

What kind of chassis are you using? Are you including the CPU in this cooling loop?

vig1lant3: I want to cool the video cards, I don't see an issue with my CPU it is cooling just fine. This set up would not need to be mobile, best would be low to no noise. Looked at the blocks, look good for the twin GTX470's now would need some help with radiator and pump. I do not mind if this is outside of the case (box,chassis,computer case).

What is different now with both GPU's is the lag on the input side...keyboard and mouse seems to lag now?

Thanks E

Need to know what chassis we're working with here before we look at radiators.

Have you updated the nvidia drivers?

Chassis..? Not sure what you need from me.

2 GTX470 Asus cards

drivers are up to date.

What model case are you using to house your gear?

Oh, and did you want to overclock the cards?

I'm using an XSPC 360 rad and it works well. Make sure to get some good fans if you want it too be quite and have good numbers. Scythe s-flex or something.
As far as the lag I would try adjusting the affinities with process lasso. Or restart your clients can also fix the problem.

I run the sli 570s to fold with so its a pretty similar set up.

cases do make a huge difference in how this cools. if you are cramming all that into a mid tower or god forbid a mini its never gonna cool off unless you move to staypuffs house and hunt polar bears with him.

water cooling will only get so much down from ambient eventually you will hit a diminishing return point. your biggest issue and I am in south florida so I get HOT here, is to exhaust your heat out of the area. ideally a external vent to outdoors or at least into an exhaust area where your pc aint would be the goal.
the 470 run even hotter than my 570's and mine are in a haf 932 case with LOTS of fans in it.

and with these cards eventually you will give up on cpu folding, it just lags it all down. my 2 570 make 30,000ppd ez. the cpu actually slowed my ppd down by almost 5000 points! it just made sense to ditch it in my set up. your mileage may vary as always, and please to keep us updated!

show us a picture of the innards if you can.
at the very least a model of your case etc to give an idea of what you are working inside of.

oh yeah, bi weekly minimum dust bunny patrol keep them cards dust free or they will NEVER cool properly.
