Hello everyone, today I've finished my first rigid tubing watercooling build. Before that I've used only softtubing and was only cooling the cpu. I've now included the gpu's, but I have very hot temps with the hydrocopper block. They are nearly as high as under air.  Calitemp 1 & 2 are the water temps, as you can see both 2080 Ti's are freaking hot. I've tried different Pump speeds/fan speeds etc. The CPU loop is a second loop unaffected by the gpu loop, wich is cool and working properly. The GPU loop has two rads, 360 and 480. I've read in some threads that this could be because of the silver/black bracket around the die, but others say that it isn't even high enough to make contact. Don't know right now where to begin or what to fix to get normal temps. Also here a picture of how the gpu's are connected with each other.  Flow direction is from the lower left to the top right. Greets esschallert

I just finished dealing with the exact problem you have and I just ditched the whole bracket to get my temps down.
I took some measurements and the bracket looked like it had no interference with the block at all, but for some strange reason it wouldn't get full spread with it on. Took the bracket off and the spread on the block was almost the exact size as the die from just fitting the block with no screws, so I ditched it. Nice looking build by the way.

Yup.. gona sting to remove the gpu's again and the blocks from that loop.. yeah I'd say ditch the bracket but please check to see if those screws for it are possibly too long to where there sticking out out of bracket first.

Ok I will check that on sunday sadly no time till then. I've used the longer ones as described in the manual because I'm still using the original backplate. RustyBrownEye

Wouldn't that mean more Stress on the pcb? What are your temps right now after removing the bracket. I've read on the forums from some people that they have low 40 with the bracket under load.

I have 38-39 with the bracket on. But put the brack on upside down at first and it grounded out so the card didnt work. Shiny side up and extreme tight screws no problem with contact.

I can't readout that image you posted from Aquasuite. Can you type out the temps?

GPU (Main) 79°C
Watertemp 29°C
Roomtemp was around 20°C,
GPU (Second) 59°C
This was after around 10 Minutes of timespy extreme stresstest, near the end of the test the benchmark froze and the nvidia driver crashed.
Clocks where 1000+ offset to memory and 100 to core, worked well under air with around 85°C, now nearly the same temps with water.
Weird is also that every benchmark or ingame benchmark like shadow of the tombraider offers, are crashing now, under air every benchmark and game worked fine with the same offsets, now the nvidia driver crashes instantly or after a few minutes.
When I'm back at saturday evening sunday morning, first thing I will try is to tigthen all the screws more.

If it crashes it's probably unstable OC's. I would just test everything in stock to make sure it's not the GPU. Your temps do seem high for custom H20. Something ain't adding up. Your water temp looks good but you shouldn't be getting those type of GPU temps. You might need to reinstall the blocks on them unless htey already get preinstalled directly from EVGA. What's flow like?

That's weird because before with the air cooling the same oc was stable.
Yes first thing i try fasten the screws, if that doesn't do the trick I have to take it apart and try to reseat it.
Flow looks good, sadly I've no flowmeter

No worries, I think you'll get to the bottom of it. I think having a flow meter is a great idea, especially when already having existing AC products. Is this an AQ6 you're using or just a Quadro? If an AQ6, grab a flow meter like this and this cable that needs to go along with it for operation and connected to the flow header behind the AQ. I can't tell you how many times that same flow meter has helped me identify issues with my loop. It's great to have and a piece of mind of how healthy your flow is.

So I've now fastened all off the screws, some were pretty loose. This was around 15 Minutes of Heaven benchmark https://i.imgur.com/hhXkazq.pngRoomtemp: 25 °C Water: 33 °C GPU Main: 49 °C GPU Second: 47 °C Fans used, ML120 Pro, at 60 % Pumpspeed at 90 % This one was timespy extreme stress test https://i.imgur.com/nhVY7gt.png Roomtemp 25 °C Water: 35°C GPU Main: 53 °C GPU Second: 52 °C Fans at 60 % Pump at 90 % since it's my first time with GPU's watercooled, are these temps are any good. They are much lower then before (before i tigthened the screws) but still they seem pretty high to me. Since somewhere I've read that they at around 40 °C under loard. Hope someone with experience can give me advice. One more thing I will try for now is fans at 100%.

Well better.. tuff to say since your room temp is warm at 77f. I run mine around 70-72f max. (Basement.. sometimes it can be 66f hehe) 38-39c durring bf5. Single 60mm thick ek xe 480 rad. D5 pump at 100%. Push pull fans corsair sp120 hp but running at like 75% (I think) using the included resistor. Of course all that with GPU overclocked at 2190-2205 and mem at either 8400/8450mhz.

by any chance do you have 3dmark and could run timespy extreme stress test? Would be nice If I had something to compare to.

Try running a serial loop instead of a parallel loop. This should help with your temps a little bit.

If you try that, it looks like just shortening the length of the bottom tube so it connects to the right port and remove the bridge tube above would be easiest.. that way you dont have to make all new hard tube runs.

Also I forgot your running 2 cards.. that means the top card would be working harder and warmer. Especially with the flow direction of the bottom warmer water hitting the top card.

In my system, it did, but I made sure the top card was getting the coolant from the pump/res > radiator so that it was as cool as possible. Since the top card tends to run warmer, this sort of equalizes the two card's temperatures in my system since the warm water runs to the cooler card. It may help keep your card cooler, or it may not. Each system varies. Always worth a try though! -Jacob B.

Yeah that's one issue with the bottom card getting it first, but that was or is right now like the best way to route it, unless I redo the complete gpu loop. Currently its like this res>pump>rad>second gpu>first gpu>rad>res I've now taken all apart and refitted both of the blocks. Here are some photos of the thermal paste spread. GPU 1 https://i.imgur.com/l1tYTgD.jpg https://i.imgur.com/xfMEL78.jpgGPU 2 https://i.imgur.com/xHx608L.jpg https://i.imgur.com/CtrJRwJ.jpg Looks to me like a bad spread pattern on both, the second one a bit better then the first one.

Thermal pads look pretty smashed. Good contact there but wonder if there a little tall and not letting the GPU get a good contact.
Its spread so its touching though.

I think the way its plumbed between the 2 cards it will short cycle or almost deadhead at the pump , your going to maintain the hot cooling in that loop , it should be in and out just like a car radiator .

Only 1 way to find out and that's by doing it the normal way in serial. Though yeah in at the top card would most likely be best.
Thet was the first time I've ever seen someone do it backwards and thought it was weird but figured they had to route it that way.

I'd hate to suggest it.. but if it's still hot. Maybe tey mounting the card real quick with no pads on the ram. Meaning straight paste on the ram. That would be best for them anyways if the block would make contact with the mem chips bare and no pads.
Only way to find out would be to paste up the GPU and mem chips and screw the card to the block and then remove the card to see if the mem chip paste is spreading and making contact.
If so leave the pads everywhere else..
So of the mem chips are touching with no pads then no doubt the pads are too thick and preventing a good strong contact with the GPU die.

I can answer as well ;) Goto http://www.performance-pcs.comI'd use PETG..way easier to deal with a form. Not brittle and wont crack easy like acrylic tuning. I've even bent a tube wrong and just heated it up again to straighten it out and re formed it like I wanted. http://www.performance-pc...ult/?o=Pekq&q=PetgI went with EK 12/16 tubing.. Whatever ya do make sure the fittings you buy fit the tubing and obviously use the right size insert to shape your tubing or it will just calapse on itself.
