Fill a loop without bridging the pump ?

[Sash2126]

Hello everyone, I have just finished building my new rig and I made a custom hardline loop. I have air leak tested it at roughly 0.45 bar for 20 minutes, and it isn't leaking. Now I'd like to just rinse it with distilled water before putting the coolant in. I read that in order to fill a loop, you have to bridge the 24 pin cable to start only the pump. The situation here is that I do not have enough access to the motherboard end of the 24 pin cable as shown below.

So if you could enlighten me on how could I fill it without bridging the cable, I'd truly appreciate it!

What power supply?

Power supply is a Corsair RM1000x 80 PLUS Gold 1000W!

That's just a type 4 unit. You can do the same thing by unplugging the 24 pin, gpu power cables and the cpu power cables from the power supply then jumping the right posts on the power supply it's self.

 

It's a type 4 unit, so "Power On" and a ground.

Thank you very much, I'll try this tomorrow morning and come back to report on how it went !

The water goes first at the top of the distroplate, but you can't see it from that angle, well it's really custom. I had to saw the top of the case in order to have access to it. It goes like this: Distro -> GPU block -> Back rad -> Distro -> CPU block -> Distro -> Top rad -> Distro, rinse and repeat !

Here are shots from the top and bottom of the case, you can see the filling port right in the middle:

It also looks like you might be able to disconnect your top CPU hardline and get the ram out, remove the 24 pin. Then put the hardline and the ram back in. I don't see why that 24 pin can't get connected with the tubes already attached.

 

Also, are those rgb extension cables? Just remove the extension cable from the 24 pin coming off the power supply and jump it that way.

 

Looks like you've got many options.

if water hits the the cpu first or fast, u can just fill the loop and start the pc,, it wont overheat

It's probably not clear on the pictures, but I can't really fit my hands in there

I was thinking about filling with distilled water as much as possible, then start the pc, once I have room to add water, I shut it down, pour water again, and so on until it's full. Maybe pause for a few minutes inbetween fillings so that I'm sure it doesn't overheat ? And then repeat the process with the actual coolant..

yes, many youtubers do this. and also somthing very important:  no modern cpu can be dmg'd by overheating

Yeah I've got a 13700k in there so I guess it's modern enough. Do they shutdown to prevent overheating ?

yep at 105 they shutdown, no problem

Great work for your first loop.

 

Is that a 120 rad on the rear?

 

I recently finished a Hyte Y60 build with the corner distro plate.

The PSU just needs to run to power the pump - just the SATA or 4-pin Molex...or whatever is used to power the pump.

You can completely disconnect power from the motherboard, GPU, etc.

If the EPS 8-pin, ATX 24-pin, and PCI-E connections are extensions, just disconnect them from the PSU end.

 

If the PSU is bridged on the 24-pin connector end, the on/off switch on the back of the PSU is what you use.

1. Fill the res/distro plate with water. 
2. Flip the PSU switch to the "on" position.
3. Watch the pump start to push the water into the loop.
4. Before the res/distro plate runs dry on water, shut the PSU off.
5. Add more coolant.
6. Repeat above steps until there is enough coolant in the loop so the pump is constantly fed -- so not running dry.
7. Top-up the coolant with the pump running, no need to turn it on and off.
8. Let the entire loop run for a few hours (or overnight) to cycle the air bubbles out of the loop.
9. Top-up the coolant on last time.
