Gents,

Pleas help me out here - I've managed to work the coolant round most of the loop and have filled the reservoir twice but cannot get all of the air out between the block and the suction of the pump. I'm not sure if this is because the pump is not strong enough or if the air is so tightly trapped or because my piping arrangement is bad. Can you answer me how best to proceed without blowing out the pump or avoid re-filling .if i need a new pump so be it.

you should rearrange it to go res to pump. if your going pump to res the pump is still going to suck in air when your filling the loop. it'll make everything 10x more easier.

Starting to think maybe I should have pumped from the res, not to it. I work in mechanical engineering and it's fine is almost every system to pump to a tank but I'm now second guessing my arrangement.

see if you want to achieve maximum cooling in a system you take the shortest route from the element (radiator in this case) to the source (CPU) so there are no gains/loses between the two. I cant easily achieve going to opposite way due to the nature of the fittings/hose/case etc. Pump is making a bit of noise now, i've worked most the coolant around the system but not sure if pump is dying or just really struggling to get the last of the air trapped out? see below:

pump noise now

got to this point and now afraid to turn on again :p

are you going from RES - Pump? sorry i cant tell in the photo's
if the whole loop is full you can tilt the case around to get all the trapped air out. Thats how i got most of mine out but there will still be air in the loop for a while.

no from pump to res! I've worked the air all the way around a few times now doing some gyroscopic tilting but the it's not going back to the res or is going there working back into the loop. really frustrating because it's been so close a few times to having worked its way out.

will it help if i remove some coolant?

just cant seem to get a good flow of water around the loop - the air is constantly making it way around never staying in the res to pressurize the system. think i either need a stronger pump or rethink the arrangement so water draws from the res, not from the CPU block and back to the res

Well I think i blew my pump as there is 0 suction now. will have to buy another and will opt for a 400 instead of a 220 - just dont think it could manage the draw and be able to pump to the res, through the rad and the block.
