As far as I can tell, that pump / combo as three inlets. Two in the reservoir & one in the pump. So yes, you do have an additional inlet to open to bleed air.

Think about it logically. In your diagram below, your reservoir & pump are at the bottom of the case. To fill it, you will have to pump the water UP to your reservoir. The issue with that since air is lighter than water, air will always rise. So it will be a bit difficult to bleed those rads as air will eventually get trapped in there.

The easiest way around this is to introduce a fill port at the highest point (top of the case). Not only will this allow you to bleed your loop easily, but it will also allow you to fill it easily.

Don't want to modify your case? Your best bet is to start filling your loop as best you can. Once there is a decent amount of water in the system, close off the port you are using to fill (one of the inlets in the res) and flip your PC over to get those air bubbles out of those rads and into your res. This is very tedious and time consuming.

You always want to get the air into your reservoir vs any other component as you can open your reservoir cap and just allow the air to release.

To give an idea of how to have a setup without needing a fill port, check out this photo of my rig. Whenever I need to fill my loop, I take off the cap of the reservoir and place in a spare piece of tubing into the reservoir. The tubing sticks out of a reservoir (albeit on a tight angle as its very tight in my case) and I essentially have a straw running into my reservoir. I then place a funnel into the tubing, pour water into the funnel, and run the pump. Since my res is my highest point, its pretty quick to bleed.

Spoiler!


Is this achievable in your configuration? Probably not but just because it's not natively supported doesn't mean you can achieve the same methodology. Just need to get creative

I mention all of this because again, in my opinion, is the most crucial aspect to designing a loop configuration. It will make your life a hell of a lot easier if you can fill, bleed, and empty your loop with ease.

Thanks for the help!


I'm looking at alternative mounting options for sure but without removing the drive cage, its not going to be easy to get the res above the rads. I may add a fill pot up top though.

I don't know if such a product exists, but if there is radiator has more than two inlets, just purpose one of the inlets as a fill / bleed port. That will solve all of the bleeding concerns that I have.

Something like this will make your life much easier. Just saying

Filling is non-issue as long as reservoir is full of water and feeding pump w/o air bubbles.
Draining on the other hand is a pain if you have your drain port somewhere in between and no top port that can be freed.
So I'd recommend separating the pump/res combo into 2 -> pump bottom mounted to chassis with vibration dampening material, and reservoir that can be placed higher than radiator temporarily.
By temporarily, I mean longer tube so you can have it on top of your case while filling, and out of the chassis when draining (with case upside down and reservoir in the sink).
This could be achieved if you give some slack on the tubes running res -> pump, pump -> gpu, and return line into reservoir. Simply mount after filling is done. Dismount when draining.
