Liquid from Res is going OUT THE IN port

I just got my CM ATCS 840 and took the loop from my armor and added new rad and res to the loop. The 3*120 radiator is mounted in the top of the case, and I have a XSPC single bay reservoir in the third highest drive bay so I can pop out those brackets when I'm filling the loop for easy access.

PROBLEM: The reservoir has clearly marked idiot proof IN and OUT ports. Now relying on my understanding of IN means the reservoir is designed to take liquid in from that port, I hooked up my loop to feed into that port. And like wise, I assumed that the port marked OUT is optimized to push the liquid out of that port. NO SUCH LUCK!!!!

My loop is set with MCP355 on the base of the case/to a dtek fusion v2 CPU block/ to a Koolance CHC-122 NB block/ to EK 4890 block/ to MCR-320 rad mounted in the top of the case/ to said sad reservoir very near the top of the case.

The resevoir fills up and starts to go backwards in the loop, against gravity to the radiator instead of to the pump!!!!!!!! OUT THE PORT MARKED IN!!! There is clearly an acrylic semi circular cap creating an air bubble which covers the OUT port. This is the most ridiculous crap I have ever come across.

I went directly to XSPC's website and pulled the manual XPSC manual . It shows the liquid in photo 5 in the IN tube and not the OUT tube.

Am I ok switching IN and OUT ports to get some liquid to my pump? Am I wrong in assuming that something marked OUT is supposed to be the port that the liquid goes out of? Anybody else think this is ridiculous?

P.S. I had to take a turkey baster to the res to empty out the RES because it started to overflow rather than go out the OUT port.

no, you do NOT pump water in through the "IN" port. do you have your pump shooting water into your reservoir through the "in" port? are you expecting this would push the water out into your rest of the loop via the "OUT" port?

you're supposed to have tubing come from the "OUT" port of your reservoir into the "IN" port of your pump then out of your pump throughout your loop then back in to the "IN" port of the res.

got a pic of your case?

Thanks for responding Louisssss. That's the only thing that made any since considering what was happening when I filled the res. The air pocket of the OUT port makes no since if the water is supposed to flow out of it.

That is so confusing though. Was thinking that if you go to a store and a door is marked ENTRANCE you go in through it and if a door is marker EXIT you go out through that. It makes perfect since to me that would correlate with IN and OUT. Guess not.

anyhow heres a pic of the loop and this is the res. Please forgive the mess, I have not cleaned up the wires up and tubing! :Q Also forgive the low quality cell phone pics. G/F took the camera on a family trip.

I may have misread Louissss post.

So I've been emailing XSPC support and they say that there the OUT port is supposed to go to the intake of the pump which is the way I have it oriented. What it did was fill up until it began to go out the IN port. It traveled up the tubing attached to the IN port which goes to the radiator above it. When the reservoir was completely full it began to over flow from the fill port with the twist-off black cap. Nothing is flowing out of the reservoir's OUT port and it is at 400 ml level for over 36 hrs and not a bead has flowed w/ gravity toward the pump.

Any suggestions on how I can get the liquid from the reservoir to travel to the pump so I can turn it on and fill the rest of the loop.

The output of the pump is not directly connected RES. the OUT port of the res goes to the intake of the pump and the pump goes through all of the blocks and then radiator and finally back to res.

I do expect the pump to push the liquid through the entire loop and eventually through the out port but that would be the end of the loop not directly feeding into the res. It's my understanding that pump to reservoir could create bleeding problems.

You need an inlet line that runs up above the rest of the system to the fill port of the res for filling. It need not be connected to any fill port mounted in the case as long as it has a good cap and when open reaches above the case. Here you will see four lines to the top of my case, two, from the res to DD fill ports and two T-lines that are capped and hang free that can be stretched outside the case.

The outlet in the single-bay looks like it has a little plastic blockage to prevent unwanted currents. It looks like it requires the water to be a certain level in the reservoir before it will let water out the OUT port, which means the majority of your loop will need to be filled first or tilt your case or use a t-line between the res and the pump.

I considered putting in a t-line somewhere after the resevoir but it looks like you placed your lines between the out ports of the blocks and the radiators. I'm assuming that placement is a good spot to drain the block from?

I finally eliminated the air pocket at the OUT port by filling the reservoir to capacity, closing sealing the cap as tight as I could, removing it from the 5 1/2" bay and then rocking it back and forth until the damn thing was pushed aside. the rest of the line filled up quick and there hasn't been any issue since.

The T-lines I'll put as far away from the res as I can just to help drain bleed and fill, no particular location is best for all.
