Are air blockages a real problem

I’ve recently competed my first water cooled build based on the Evolv Shift X.

No matter what I’ve tried I still end up with a air pocket in the cpu block and air in the tube between the cpu and rad. I’ve tried different pumping routes, and even different pumps, but to no avail. At rest the cpu block is empty, in use around 75% covered. In the Evolv you’re stuck with having the cpu at the top and the reservoir at the bottom.

there’s still fluid flowing but it doesn’t seem that great a flow. At idle the cpu runs at around 50c with a coolant temp of 33c post cooling. It’s a ASUS b450i with a ryzen 9 3900. I’m using a 280 radiator and D5 pump/ res combo. All parks are ek with a mix of hard and soft tubing

No overclocking as yet, though I’m keen to try, in fact that’s why I wanted to try water cooling.

I’m waiting on an RTX 3080 which I’d like to watercool, but am not comfortable about trying that while having air in the more simplified rig.

should I worry ?
 
Agreed just run as in leak test and make sure you tilt the case all sort of ways,make sure your cpu block has the correct jet in also.
 
Agreed run the pc with just the 240v cable, pump at max speed and turn and tip the case until it’s gone. I usually sit my pc against the wall at an angle and leave it like that for 20-30 mins while the air is removed.

You can also put 1 drop of dish soap into the coolant which will help remove water tension and release stuck air.

However also check for restrictions as air shouldn’t be getting stuck in the tubes that says to me very low flow rate.

Hopefully a couple of photos. The pump res at the bottom the rad is mounted vertically with connections at the top and the cpu block higher still.

I’ve tried running the rig in all sorts of positions, expect upside down, just using the pump. Any air rises when the rig is powered off and I think sits in the rad when it’s on. I’m struggling to move it from the rad down into the reservoir.

I have also run the pump independently through both the cpu and rad without any blockage. It’s only when it’s all connected that the air block.

Image isn't loading, literally shake the pc
 
Are you hard tubing or flexi? If you're using soft tubing you might be bale to take the res pump off the mounting and lift it higher then the rad with it laid on it's side or front to force the air out and into the pump/res. It's a pain when you get a stubborn air bubble in your loop
 
I’ve had some success. By reversing the rad connections, so it’s now pump rad cpu pump, not pump cpu rad, the main blockages have gone and with 95% of the cpu covered the cpu temps are down to the mid 40s. I’m now sure I can shake the rest out.

it’s currently a mix of a soft and hard tubing, but now I’ve the air sorted I’ll hard tube the rest of it once the 3080 arrives ( if ever)
 
I have air bubbles in my cpu block right now, Ive had them before and got them out before but cba right now and not harming anything
 
In a coda to this thread, I finally worked out what was wrong. The cpu orgibally came to me with a intel fitting. In fitting the AMD frame I inadvertently had part of it oriented the wrong way. Once reversed all my issue went away. A case of RTFM I’m afraid . Anyhow all is now well apart from me bricking my GPU, written up elsewhere
