what monsoon res/pump combo?
Like this one, with a D5 pump?
the rad might be one of TT , its difficult to make out , but it is a 120.2 (240)
If its a TT, it might even be an ALU one, which is definitely reason to get rid of it.
At some point in the future you'll have to get rid of the puny TT tubing and replace it with decent 10/13. The current hose looks like it is typical TT green 6/8 , and that just wont do. And at that point you'll best change all the fittings to matching barbs or compression fittings
Actually, its best to take the whole thing apart. Clean up, throw the old hose away, get new fittings and decent hose, and re-do the loop.
The Watercool HK is a very good block, but shouldn't be that restrictive.
Either there is a big bubble trapped inthere also OR... its gunked up with debris. I'ld say to take the block apart and keep the ketchup nearby
Instructions are on the Watercool website
And when you bolt it back in place, turn it 180°, which will be better to push air out in the future.
I think that somehow the water level gets to low and allows air to "sucked in" which of course promptly gets stuck in the rad
For now, unbolt the reservoir.. it would be nice if you could slide it into the case. Rest the case on its back (right side) and lift the res as high as the tubes allow. Keep it in place with whatever you can find.. rope, barstool, bookstand, ... open it up for bleeding and gently move the case and tap the hoses & rad until no more air comes out. Top up to the max and run it like that for a couple hrs/days with the occasional tilt/tap till you're sure you got rid of the air.
Note: I assume you know how to power the pump only? The PC itself does not have to be "running" for this. Cycling the pump a few times might help also.
When getting a new rad... HWLabs is very good.. but Alphacool ST30 will do very well also.. IF you do the rad-dance very well
if its impossible the slide the res inwards.. consider unbolting the radiator from the roof and lowering it (with the fittings side up) below the reservoir to get the air out of the rad... it looks as if there is enough "play" on the hoses for that.
