Bleeding loops, Tips and Tricks?

[Xrqute]

Hi guys,

Being a fiddler as i am, I'm constantly playing with my rig.

But i have come loathe trying to bleed my loop. i think i have it all clear then a few hours later i notice a new bubble (*Insert Rage here*) and no it's not from a leak or loose connection etc just air that has gotten stuck in my rads or blocks.

So my question is do you guys have any Tips or Tricks to ensure minimum or no air in the loop on the initial fill? it's a pain flipping my Switch 810 every which way trying to get the air out.

cheers,
Xr.

I had a switch 810, fill slowly till it reaches pump and top of res, pump on lowest setting turn on and prepare to keep filling don't let the pump run dry as it creates loads a bubbles. Then turn pump up a few notches keeping eye on fluid level, shake the shit out of the rig turning ect letting pump keep fluid, once you can no longer hear sloshing in radiator. Small ickle bubbles work them self out.

i know my bay holds enough water so i can fill it 100% let gravity feed the pump (i check the tube filled with water) then i can turn the pump on and it will still have water in the res above the min level and water is returning.

then i top up the res. and tip the case arround a bit (just imagine where the air will be stuck as it wants to go to the highest point) and let it run for my 20 or so min leak test.
Then power cycle and ajust pump speeds till im happy with it.
with the 3 rads i have in it now it does take a while to get all the air out though. but generally i spend about 30 mins bleeding it (that includes letting it run for 20 mins for my leak test)
and then if there is anything left its going to find its way out of the system in time any way, and i find that there is no air in the system the next day.
But i will tip it about again the next day to check.

Some people say put a drop of washing up liquid in the res.. but i dont like the sounds of that.

when bleeding the loop do you have the system all powered up or just the pump powered on an external power supply?

Don't have the system powered up until everything is all apples. if you have a leak hello bricked rig.

It's why I left watercooling, well one one the many reasons anyways, it just isn't worth it to me. Put heat in water, move water around in tubes that block airflow and heat the interior of the case, them remove the heat with air. Why not just remove the heat with air in the first place, looks neater, the airflow improves and it just works better for me.

Depends on how messy your loop is, doesn't restrict airflow that much unless you have an utter birds nest and square pipes, and as for being better...

Oh dude water cooling, OC'ing, playing with my Rig is my bread and butter i love it......... like right now I'm lacing my cables lol. I'm just a fiddler and always need something to do and if i don't have something to do I'll make something to do.....But bleeding the loops is just tedious as it can be that one road block before you get to play with the finished product.

In my new layout I'm stating hopefully today if the parts arrive ill be adding in a Remote fill and remote drain to hope full alleviate this issue.

I just said air works better for me. Water might be fine for you, but for me, it's gotta be airflow to the max.

water conducts heat a lot better than air. you can also provide a larger surface area with radiators than with a heat sink. and also with radiators you are dissipating almost all of the gathered heat outside of your case.

a really big advantage is being able to have fans on really quiet.
i can run intel burn test on my overclocked system and stay at well below dangerous temps. and my fans only ever need to work at 20% speed. so even when stressing the system out to rediculous levels i can still keep the system quiet.
That is however a custom loop.
when it comes to AIO units. you are probably better of with the best air cooler possible compared to an AIO.
but really water cooling is a lot more efficient at removing heat from the system. And it also doesn't dump the heat in to the case like a heatsink and fan does.
it is the best compromise imo. you can get phaze change coolers that cool a lot better than water or air.
but water is the best for keeping your system at near ambient temperatures.

the best air cooler cant compete with a good custom loop. But all tat radiator space does take up a lot of room.
and if i set it up for you, well it could have looked better lol. but i dont water cool for asthetics. i really do it for the temps and noise levels.

Because you cannot overclock on air as much as you can with water.

Take an avg Nvidia GPU at stock temps taxed to the max,

Air temp = 80C
Water = 40C

And Airflow isnt improved just by using stock fans. You can still be dumping alot of unnecessary heat into the case if your chassis fans are not set correct. Radiators (with fans) can assist in creating positive air pressure and thus improving air flow just as much as a non watercooled system is, sometimes even better.

This isn't a defensive rant at you. I'm just stating that every setup is different.
