dont really matter if u r picky the radiator after pump cause pump produce heat as well so that way it gets the lower temp coolant as possible but yea thats if u r really anal ; ;

let it run for a while to properly blled the system my old system with a swiftech 320 + 240 after bleed will only drop about 1-2 cm of the res lvl but looking at ur pic u nearly fill ur res to the top ; ; half way is a good starting point

yes, that's the way. not necessary to fill coolant fully in ur res
just make sure coolant surface exceeds the top tube is enuf.

give u an idea on how the radiator works

just realized that ur res is V2 haha no way for waterfall effects
do like wat this fella said

u can do vertical flow with X2 basic and adv only. link
don't think V2 has this kind of bottom accessories.
actually u can route the tubing thru PCI slot opening there but it's going to touch that slot. ur tube is too fat 

wow i missed lots of discussion liow..
hehe..

eemm bitspower x-station
is all in one fan port and others accessories
like ccfl that used molex power output..

Specifications:

    * Molex 4P Input (Male) X 1
    * Molex 4P Output (Male) 12v DC X 4
    * 3Pin header @ 12v DC X 4
    * 3Pin header @ 7v DC X 4
    * 3Pin header @ 5v DC X 3
    * Lighting via Two Bright LED's

dzx show me too i wan see that hw u put =) newbie here willing to learn...
btw sub... u r hokkien lang?

i m hokkien lang too haha =)
anyway gd luck for setting ur wc =p
and where u live dude

nope u just direct plug the 3pin from fan to
the fan port male 3pin,..u can choose either 12v,7v or 5v
output.. from the pic..the left 3pin x4 is 12v..the right is 3pin x4 7v..
the top 3 is 5v..

hi bro,

there is no such thing as "...but i found out that the res no enough capacity to filled my 420 and whole loop.." in WC...its a close loop bro, u can be using a mullti res 100mm and still run ur loop, or u can even scratch out the res altogether and run with a T line instead...a res only purpose is for ease of use..thats it, u can use big/small/long/short/single bay/dual bay etc doesnt make a difference...ur problem with that setup is bleeding...since ur res its postion that way, means during bleeding, the air buuble has no where to go but up, in your case is the rad..so top potion of ur rad is fill with air..if u do the res inlet/outlet at the bottom, will give u a water line in res, so the air will be trapped above the water line, just unscrew the the top a bit and let the air out..so, either u need to redo the inlet and outlet of the res at the bottom (which is more ideal..) or if u r the advanturous type, maintain the setup, but add a fillport so the air can go out that way, but word of caution, i've done this, its doable but its pretty hard to bleed...

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. 

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?

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

Haha..rad where u place also ok 1..d problem is u need to stop d coolant flow out frm d rad when u off that pump..d coolant wil flow out frm rad coz of gravity if dun hav pressure force that coolant to stay at rad.so if u can control d coolant flow out frm d rad is ok d..hahaha.

he can just bleed with tubing method i mentioned, then buy a stopper/ fillport, fill the reservoir full while tilting the case. no need worry of air anymore...  juz like wat vlad suggest... 

its actually quite easy if u know someone that has milling machine
