I recently installed a hydro copper block to my rtx 2080 xc hybrid to add into my loop. Temps are not ideal though. From what i've read they shouldn't be going past 45c. Mine hits 60+ , The hybrid did better even. I have checked my rad , added another rad which actually made it a few c worse. had liquid hit ram before gpu , gpu before ram , gpu is first in the loop before cpu , flow , fans , everything. I've drained the loop and re pasted the card about 10 times in the past few days just for the hell of it . with little to no change in result. I just can't seem to figure out what the issue could be , besides a bad block?

Within a minute or so , it jumps from idle of 29ish straight to like 55-58c then continues to climb to 60+. CPU temps are the same , with or without the second rad. 49c max. (3900x) or before or after hydro copper install. 

so pretty much RMA,  or get the ek velocity?

I've re pasted using the included paste , thermal grizzly and noctua NT-H1 , a couple times each.. every time i pulled it off it looked great. Can't seem to spot an issue with the mounting. But I'll give her one last try. 

Give us a full listing of your PC and the liquid cooling used.

I noticed lots of tubing entering that reservoir.  I don't think that many are needed as it could decreasing the flow quite a bit, not to mention how restrictive the GPU block can be.  Without knowing what your flow rate is, it's hard to tell atm.

Have you tested this by running all the fans and pump at full power?
 
Also, I would have kept 3 fans as intake at the bottom and just place the single rad on top of it with another fan on it for P/P since without those intakes, you don't have many places of fresh cooler air being brought in along with a rear fan to help exhaust that internal warmer air.

Do you use a filter up top?  If so, turn those fans to intake with the rear used for exhaust.

Apex ICS distro block - ddc pump i believe. It has a built in flow sensor and at full speed throws 54 L/M. generally i have it set to around 55-60% so 45ish L/M with indicates plenty of flow you'd think. loop order is out of the distro block/pump -gpu-cpu-distro-rad-distro. the distro has that passage at the top. I could put plugs in those 2 ports but i just ran lines for them instead.
360mm nemesis gts rad. 
ek cryofuel for liquid
The fan configuration is 3x bottom intake with dust filter- 3x side intake with dust filter - 3x top exhuast/rad. I also added a bitspower leviathon 240 XF as a bottom intake and exhaust (tried both).
 
I Just redid the card and paste before i saw your posts , but i will take it apart now and take pictures this time.





 

 
  







 

I posted a picture in above post of my last thermal job. i'd imagine this one looks the same.. but i removed those 2 tubes / that passage on the distro and re pasted again as usual , this time she's maxing out at 47C with air still in the lines. so i'm thinking this time it's good. Wonder if it was that passage or the paste?

I think it's your passage.

Might of been , May have to flush and find out. Is 48c still a little on the high side?

It could be cooler but that all depends on the loop, ambient temps, etc.

Did a little digging , pump is a bitspower touchaqua S1 , according to specs it puts out 960 L/H. Ambient temps in the room are generally 19-20c. Some of this is a little confusing haha... Converting L/H L/M , GPM etc.. How much restriction or what can this pump realistically handle? Thinking on buying another nemesis 360 gts for the bottom to see if that helps any further?

Not a bad pump.  It's a 17w DDC running full bore @ 960 lt/h = 4.2268 gal/m.  You got a good powerful pump.  DDCs are known to have better pressure than D5s in complex loops like yours but are louder than D5s is one of the tradeoffs.
 
I think at this point, I would focus on your configuration of the loop.  Loop order doesn't matter as long as the reservoir is feeding a pump because a dry pump is a dead one. 

You are using a 16 FPI 30mm thick radiator.  For the temps you're getting and how complex your loop is, I could see why the temps are the way they are.  The issue is, that case has been known to not give great temps because the way it's designed (aesthetics).  If you fill the bottom and top with rads, where is the fresh air coming from?  If you say the triple side fans as intake, you're actually intaking the rear exhaust air from the back into the case which will cause temps to rise.
 
Presuming you have filters in both top and bottom and you add the same rad from the top to the bottom, run them both as intake so they get that fresh air in and than run the side and rear as exhaust.  That will allow your rad fans to intake cooler fresher air while the rest are used as exhaust.  That should take care of the air flow.  

Next focus on those distro block.  I'm not too familiar with what goes where so you might need to reevaluate.  If you had it setup fine originally, I'd leave it alone.  

I actually have that case (o11D XL). Side and bottom intake and top and back exhaust (6-7C water above ambient temp at full load during a game). 3 rads ofc. All fans at around 1100rpm, noctua a12x25. Opening the case drops temp by amazing 1C barely (top rad thing)

Right , this one sure has me puzzled. I do have a thick 240mm rad laying around if that would suffice for a test? same FPI from the specs it looks. Odd enough my cpu temps are a few C higher lately also. probably the heat from the gpu.

My guess is flow. Maybe the CPU block is clogged up or is restricting enough to slow the flow threw the while system.

Try to max the flow of the pump.. remove the side door and remove the filters covers as those may be to fine and restricting air flow as well.

The big rad at top should be intake.. all rads should be intake.

Max out those fans.. at least 75%.

Still guessing clogged or slow flow CPU block is doing a number on the flow.

Swapping out the GPU that many times and refilling may of got some debris in the fluid which is now stuck in the CPU block.

Be nice to test just the GPU block without the cpu block in the line to find out.

I did try taking off the side panels, removing the dust filters etc. maxing the flow doesn't really give any improvement but it seems to be good and the block doesn't appear to be clogged , but maybe. Fans are set to 80 or 85 percent. lower/higher really didn't make any difference though. She generally hits 51-52c after a  half hour or so of warzone. I ordered a second nemesis gts 360 today , some more ek blood red cryofuel , and a g 1/4 water temp sensor and led display. Still have a half gallon of deionized water , should i give it a good flush with that and just run the new bottle of liquid?

Colored fuild.. no no. Flush it take the CPU block apart and take pics. Let me know ;) please for your mental health.

My idle temps like room temp.
