subrok, i think ur loop dont have enough place to let the trapped air out... u can always connect a long tube from the filling point of ur reservoir, make sure the tube outlet is the highest point and tilt the case watever direction u like ( most adventurous and quickest way to bleed ), I always did mine this way, just making sure u tilt the correct direction and didnt spill anything. Oh ya, leave pump on but PC off during tilting.

u mean connect a long tube to filling port and make it at highest point (hold by hand) then start tilting casing rite??

ya... u connect a long tube out... tilt the case and let the radiator outlet at top...

and fill the tube full, u will see water level dropping...

subrok
how many times u fill your loop?

because from the promblem that u face..
imo seem like u dont fill your loop fully and
and your loop is not enough water to recycle
back to res before it empty..

i think hes referring to the trapped air pocket from the rad, pump pushes water into the rad and force air pocket into res, once pump is off, back presure pushes the air back into the rad and water fill the res...

or as Dz said, simply not enough water, pump pushes water into the (almost) empty rad, once pump is off, water goes back down (gravity) and back into the res..

Haha..r u already changing ur inlet at bottom position?

Added on August 23, 2010, 12:54 pmHaha..if i nt wrong,when d pump running,it got pressure to push d coolant up to d rad,same thing,when d pump off,there no more presure to hold d coolant inside d rad..so d coolant wil drop back to rev..for exaple u take a paip,u close d end of that paip,then u fill d water in d paip,d water wil stay at d level,coz ur hand is d pressure to make d water stay at d level..bt if u let go ur hand,d water wil pour out,coz dun hav pressure to push d water to stay inside d paip..haha

ok will try it.. thanks for advice...


i just fill about 2-3 times only... but after i off the pump, the water reverse back to reservoir till full.. so i cant fill again lo.. then i tot it was full in whole loop... but i just realize i was wrong.

any idea?

yes almost that situation...

i only can do right now is fit a long tube into fillport and hold the tube higher than radiator.. filling water simultaneously while pump is on.. am i rite bro?

nope.. i wan overcome this problem 1st b4 change

Haha..i dun thk can settle d problem,except u put d radiator at d bottom..mayb wil ok

ya, trapped air in the rad... the setup he done very hard to bleed, need some tilting as radiator on top...

101 for bleeding, air always go to top of the closed water cooling loop as the density of water is higher than air.

wat I suggest subrok is to lay down the case, hold ur reservoir with hand so that the reservoir is on top, turn on the pump, the trapped air shall escape from the loop, and keep filling the reservoir untill full...

alternatif is the tubing method, join a long tube, hold with hand, tilt the case watever direction u think could bleed the air.

anyway, both method need to be carry out very cautiously as it has the risk of spilling the water over ur precious hardware.

Oh ya, and its not about reservoir size... the tiny swiftech micro reservoir is one of the most easiest to bleed reservoir FYI.

Haha..d better way is changing d inlet at bottom,all problem solve d..haha

very good explanation... very thankful all of you wc kaki here...

i will follow your instruction bro...
FYI, i cant hold the res vertically if i lay down my casing due to inlet pipe is measure to that particular length.. what i can do is

1st - lay down casing
2nd - connect long tube to filling port
3rd - pump on
4th - concurrently filling water while pump is on.

am i rite? please advice. thanks
will do it if i still cant solve the problem.

the reason i hold your suggest solution due to i have route my tubing from top to bottom.. performance will drop and messy inside casing like worms..

not really, the bleeding for top radiator is always more difficult.... sometimes it seems ur reservoir water are flowing, but when u tilt the case, the water reduced as the air from radiator escapes...



yes, u can do that... but just make sure u didnt spill anything to ur hardware. tubing methods is slower compare to the whole reservoir at top. u will notice the water u filled inside the extra tubing lower as u run the pump. It is slower as u can imagine, escape air and water going in share the same path... u can always cable tie the tubing to a higher point, leave it there and let the pump run.

Hahaha..nw u placing ur rad at top alrdy drop perf coz d lenght of paip is alrdy long d..

Added on August 23, 2010, 1:53 pmBt if u place d inlet and outlet at d bottom of that rev,there no need to bleed d radiator right?

This post has been edited by alan kc: Aug 23 2010, 01:53 PM

for top radiator, u always need to tilt the case to make sure all trapped air escaped. cause normally air trapped at highest point of the loop. tht's y reservoir always recommended on the highest point of the loop. if bottom radiator with inlet/outlet facing up, its easiest way to bleed the whole loop. just leave ur pump run and it will bleed well by itself. you need some extra work if u bleed top radiator.

during bleeding, we bleed the whole loop to make sure no trapped air inside. not just individual parts.

Oh..coz last time i use b4 d rad at top,bt my inlet and outlet is at bottom rev..haha..it wil bleed it itself..haha..

oic.. actually the difficulty of bleeding depends of setup of ur loop. So plan well before assemble, always go for the easiest way....

for me, i always go for best looking and easiest to bleed design.

Yup..i do research 1 month b4 setup my 1st time wc..haha

ohhh ok2 .
hmm, the only solution i can think of this situation is to run ur loop and also fill them full during bleeding process .
its actually hard to do loop like that .
u'll have trouble bleeding and draining later on .

Haha..looks like he going to reset his wc again d.

try 1st .
its d last choice to redo the whole loop again .
its really tiring dude !
