There are several reasons for those temps:
- As you said, air in your loop. Bleed the loop again. The highest the res, the better. Also remember to tilt your case to move bubbles in your rad.
- Poor contact between your cpu and the monoblock/No enough thermal paste.
- Not enough pump speed.
That being said, it's not a little too much volts for 4 GHz?
My 2700 goes 4,1 GHz on all cores at 1.325V
I redid the loop (changed loop order to the correct inlet on the monoblock) and disabled my OC but it still seems to run hot, 90c in y-cruncher with all tests enabled.Which y-cruncher stress test. The BBP and SFT test will push the cpu the hardest. Not surprising at all you got over a 100 degrees at 1.35V.
I agree with Ralph, you shouldn't need that much Vcore for 4Ghz. The auto boost voltages will always push too much voltage for a fully loaded system. It is meant to only run 1 or 2 cores for max gaming frame rates.
Best to put in a manual fixed clock multiplier and then drop the Vcore down to the lowest needed voltage for stability with your intended loading.
But also likely you have air in the loop and the flow is restricted because of it. Get the air out first and then retry y-cruncher. My stress test is a run through the default tests of y-cruncher for 5 passes and if stable, it will be stable for any of my actual application loads.
I generally agree with that sentiment. Just get a Xylem D5 pump and call it done. Plenty of flowrate and head pressure. Your HWL GTS240 is considered a high flow restricted component. And your Alphacool DC-LT 2600 pump only pushes 100L/hour. That is really low for that radiator. The D5 on the other hand pushes 1500 L/hour. A much better fit for your components in my opinion.I redid the loop (changed loop order to the correct inlet on the monoblock) and disabled my OC but it still seems to run hot, 90c in y-cruncher with all tests enabled.
Starting to think it might be related to the pump being not powerful enough. Oh well, buy cheap buy twice I guess.
I disagree, a CH7 has one of best VRMs on X470 and with a Ryzen 2600 running at stock/65W the amount of heat is negligible.I generally agree with that sentiment.

Because you are using a monoblock, you will get higher temps than if just cooling the cpu. The VRM's are dumping significant wattage into the loop also.
I went with a monoblock for shits 'n giggles anyways, it wasn't much more expensive than something like, say, a TechN block.So I see no need for the monoblock in the first place since you are running such a low powered cpu and the VRM's are barely working.
I run much higher powered cpus like 3950X and 5950X on my C7H's and only need standard case air flow to keep the VRM temps in the 50's.
I still maintain the pump is the weak link in the chain. Not enough flow in the loop.
Don't care about RGB and I don't have a Octo either so looks like i'm in the clear.It seems so: Aquasuit for Win 7, but with some limitations (no RGBpx, no OCTO connected, etc)
Just a thought, but if EK's distroplates are trash i'lll go with a Aquacomputer Ultitube with the Leakshield top.See lots of forum posts about EK distro plate failures. Mainly because of the use of a DDC pump.
You already have a decent pump in the D5.
Why do you think you need a distro plate?
