You can try that your are the best judge since you can see it all.
However try to get a coolant temp sensor to see the coolant temperature.
Also check on the pump speed.
Let us know and I will be able to help you out as much as possible!
I will definetely keep you up to date hopefully with a full detailed report with images and numbers.
Coolant Temp sensor isnt at all necessary.( 8 yrs of WC'ing and never had the need for one, although I do have one in my box of fittings)..a "flow indicator" would be far more beneficial then a temp sensor imo.:
- Coolant temp should be slightly above ambient with your PC idling, so just check your GPU Temp (msi ab)...with an efficient loop your GPU should be idling very close (within a few degrees c of your room temp ((ambient)) ).
Here are my temps and information with a 3080 FTW3 Ultra (OC +125 Core / +650 Memory) w EK Vector n Nickel backpplate, room temp (ambient) at 20c (I know coolant is close to the same as GPU Temp idling indicates that):
- pump speed 3200 RPM fixed
- 9900K (EK Velocity all Nickel Block)
- 480 / 360 / 240 Rads all single fans (no push / pull) running at 1250 RPM
- 3080 FTW3 idle temp = 20c - 22c / under full load 1 hr of Cyberpunk 77 = 46c
What is your GPU idle temp (idle temp will reflect your coolant temp) vs load temp .....you had said load temp 70c ...which is far too hot for a waterblock GPU...period (unless I'm misunderstanding something).
I know the 3080Ti runs a bit warmer than the 3080, but I would think when I swap out my GPU to the Ti version perhaps the load GPU temp may climb from 46c to perhaps 49c maybe 50c...
A number of years ago running SLi 1080Ti's (all under custom loop) was playing Witcher 3 and saw my temps slowly climb and peak out at 68c....from 43c....drained my loop, disassembled both of my GPU Blocks and found some old "crud" blocking the cooling fins (within the block) on the backside of the GPU Heatsink...although had been almost 18 months since a flush..
Cleaned the fins out ....put everything back together and back to normal temps.
As I said earlier, with your high GPU temp its either:
- Pump not running properly (or at all)
- Very poor contact between GPU n GPU Block
- Restriction in your loop. (check both CPU and GPU Blocks for any bits of crud plugging up the fins within the Blocks ((you will have to disassemble then to check)) )
Please keep us updated as Im quite curious what you find to be the problem....guaranteed it will
