1st WC Loop, temps fine?

post #1 of 17
Thread Starter 
So I setup my 1st loop yesterday and I just wanted to make sure that my temperatures seem fine. I'm currently cooling both my 470s (no CPU) with 1 RX480. The ambient near the radiator is about 26-27*C. At that ambient, I'm getting temps around 45-46 on the 1st card and 48-49 on the second. Does that seem about right?

Just want to make sure that everything's working right since this is my 1st loop Thanks!

Edit: Temps are with full load (folding for past ~18 hours) with stock clocks.

Looks great. More than enough rad to cool those cards. Got pics?

Awesome I currently don't have any pics. I'll take some when I get around to doing some wire management Right now, the rad's just sitting next to my case since it won't fit in, looks pretty ghetto lol. Hopefully I'll be able to finish designing my case soon and get everything all cleaned up.

It seems a little high to me but that might be because of the sli set up.
I have my GTX 480 on the same loop as my i7 980.
Everything is well overclocked.
Full load temps on my 480 when running folding@home 41-43c.
That is with my i7 980 dumping 65-69c in the same loop.

EDIT BELOW
My ambiant temps are about 26-28c
my loop has 2 x 320 rads.

They are not okay.. especially for a 480 rad : / should be way lower... also they are not even overclocked and theres no CPU in the loop? You might wanna put a CPU in the loop too. I get 33-35c load with fully clocked card

Hmm I'm pretty sure there are no air bubbles in the loop. Should I try reseating the blocks or is there something else I should try first?

I'll be adding my CPU to the loop down the line but I figured my H50 is fine for now.

no those temps are fine but only if you are doing substancial OC on everything

I'm running two GTX 470s and your temps are better than what I'm getting...
I've got a 360 SR1 RAD and a 120 SR1 RAD.. Fan speeds are 900 RPM..

I get around 53C on both cards at stock clocks and about the same ambient as you.. I'm running DD Waterblocks, very low restriction but not as good cooling performance as other blocks.


I've got both cards overclocked to 1576 (up from 1215) and at 23C ambient the cards are at 60C running on air that's exhaust from my air cooled 1090T (radiators blowing out of the case). It takes quite a bit of voltage when overclocking these cards to keep them stable so that you can game on them and run folding@home on them in the background at the same time..

I've seen a lot of people overclock them to 1700+ Shaders, but there's no way they're folding@home + gaming stable.. I can get my cards up that high and pass most GPU stress tests out there but gaming + folding@home at the same time is unstable.. It's easy to get the cards folding@home stable OR gaming stable, but both at the same time heats these babies up fast.

The cards also squeal real bad at slight overclocks with folding@home running, but if you crank it up to the max voltage, the squeal gets so high pitch you can't really hear it.. So overclocking can actually help get rid of the squeal, unless the higher pitch bothers you..

According to nvidia, anything below 90C is "normal" for these cards and they can take it... So 60C doesn't bother me at all.

Well, the EVGA waterblocks are different from most other GPU waterblocks in two ways..
First, they're the highest restriction of all the ones reviewed on Skinee's labs which means they've got much more water to copper contact area right where the GPU is..

Second, instead of cooling the VRM directly, they've got a heatpipe that goes from the waterblock to the VRM..

So on EVGA Hydrocoppers, the VRMs run much hotter than on other blocks, but the GPU chips themselves run much cooler than on other blocks..

So it's not really a fair comparison if he's not running EVGA Hydrocopper blocks as those blocks cool differently (more focued on the GPU and less on the VRMs) and are difficult to get a hold of without buying an EVGA FTW card.

For a really fair comparison, you'd have to compare both your VRM and GPU temps to his VRM and GPU temps.. Correct me if I'm wrong, but I don't think there's any easy way to get VRM temps..

My 470's never see more than 45c. My ambient isnt even that low (hottest room in my house)
