I have since water cooled my 2 kingpin cards with Bitspower water blocks . Question I have 2 360 mm alphcool rad 60 mm and 30 mm thick for my system cooling my 2 kingpin cards and a i9 7940x Cpu all overclocked is that enough cooling. Temps are when gaming are Cpu 70 degree C and my kingpins top card 64 degree C and bottom card 62 degree C.

They say 1 120 Radiator for each Water Block as the minimum.
I would run yours Pump/Reservoir - Radiator - CPU - Radiator - GPU - Pump/Reservoir
 
OK on the Temps I can see the CPU hitting 70C but not them Kingpin Cards, mine never even hit 50C
Are you setup in Parallel or Serial, I am Parallel and the temps never have been more than 3C Degrees Difference

bcavnaugh do you think I need more radiators to cool my system or try what you said above
thank you in advance for your help I am new to watercooling

How is your look now setup?

I run Two Loops on my X299 Dark with the same CPU 1080 Ti Cards
Each Pump/Reservoir - Radiator - CPU - Radiator - Pump/Reservoir
Each Pump/Reservoir - Radiator - GPU - GPU - Radiator - Pump/Reservoir
My X99 Classified MB with Two Kingpins are setup the same.
I go a little overboard on mine Water Loops.

sorry Bill My loop is pump/reservior-GPU-radiator-CPU-radiator-pump/reservior

I would change to and see how your GPU Temps are
pump/reservior-radiator-GPU-radiator-CPU-pump/reservior
 
How are your Radiator Fans setup?
Push or Pull or are they setup in Push/Pull

TheMadDutchDude
How is it set up, as said before. Upload a picture and show us.

Be Nice, I will pass this Thread over to you and pull out.

 Thanks Bill I will change loop to see if I get better temps on the GPU,s Front Radiator is push fan, top radiator is pull fan and I have a 140 mm fan in the back. Also my GPU blocks are serial goes in one card than feeds the other card.
 

I know you might not like this but for some reason Bitspowers GPU blocs (not all of them) are crappy performers. Originally I went with BP GPU blocks for my titans, I am Bitspower fan, but when I got them and installed the temps were not great and I was juggling to try  wth. was happening, my temps were in mid 70C and nothing would really help.
 
Afterwards I got Heatkiller blocks, huge difference; temps were in 40C max across cards. I’m not too passionate about their GPU blocs.
 
FYI. and slightly off topic but its important to know....
 
In fact their famous fittings starting to act up and I’ve been using them for probably decade and now if you get some of their new fittings for hard tubing they don’t work well with other brands ( Bitspower is very sneaky and changed their ID size without any notification) their fittings have always worked fine with Monsoon, EK and Primochil tubing’s , now they tend to leak almost all of them.
 
If you get Bitspowers tubing like they suggest the Bitspower tubing’s are horrible e.g. their black acrylic tubing is purple under some light condition, scratching so darn easy, looks horrible, the scratches apply to their clear tubing's as well, hopefully they won’t drive themselves in to the grave, I've seen it happening with few very popular companies and it’s all because of their greed, they want you to get all of their components rather than giving  business to other companies, not very nice.

AWK16 only Bitspower and Byski are the only ones making 3rd party waterblocks for the GTX 1080 ti Kingpin . Evga is not selling the water block for the card any more. I am going to upgrade my case at a latter time so I can add more radiators to my system my 780T case is very limited for me right now.
 
 

Yes, unfortunately there are some limitations to what you (we) can get sometimes

Yes AWK16 I agree 
 

What were your CPU temps before adding the GPU blocks.

GGTV-Jon
What he is getting at is the blocks themselves may not be good performers and even with increased radiator size you might not gain that much. What you really need at this point is to know what the actual water temperature is. If the water is only 30-40c (with an average 20c room temperature) and your cards are running at their current temps then they are just not transferring the heat.

Go watch some Gamers Nexus videos on temperature Delta's, maybe some Jayztwo cents as well

thank you I will look into that

I Think it was around the 60 degree C for the CPU

I don't know why I didn't bring that up in a first place which is the first thing  that would indicate that  there is something up with the blocks. When my GPU's would run at mid 70C my GPU loop water was 35-39C at MAX always so there was a no heat exchange at all, so that might be the case fro your high temps.

GGTV-Jon thank you. I am going to look at my temps again for my system.

Just wondering what you used for thermal paste

Gelid extreme thermal paste

@ pozzallo
Did you want me to Post my Temperatures on my GTX 1080 Ti K|NGP|N with the EVGA Hydro Copper Water Blocks?

I am checking my temps again for my system. No need to because if I let cool air from outside in the room with the computer my temps are a bit better and the air coming out of radiator is cooler. That is why maybe think I need more cooling and a bigger case to put more radiators.
 
Thank you for the offer Bill
