TO say I am not happy is an understatement. I have just finished building my new PC and i went to fill the loop yesterday. I had intended to use ice white fluid however when it turned up the fluid appeared to be pink ( similar to a milkshake !!! ) as I was filling the loop but that is the start of my nightmare. When I had fill the loop ( the same way i always do ...fill res flick pump on then off ...top off res...rinse and repeat) I noticed some large air bubbles.so i topped the loop up ( still pink!!! ) and tried to rotate the case to get rid of the air bubbles but no matter what i did nothing would work...I could here the pump but it was as if the loop was pumping against a brick wall and would not move the air bubbles. There wasn't even any movement in the res like normal. Thinking the pump was toast I took everything out of the case and built it up out side the case ( well most of it apart from the CPU block and 1 rad ) and bingo it worked fine..well after i had nudge the position of the res. SO i spent another 4 hours re installing the loop into the case yet once again nothing it was as if i was pumping against a wall again My loop is as follows Phobya balancer 150 > DDC 1t Plus 18W >Alphacool NeXxos 240 > EK Monarch Ram Block > XSPC Raystorm > Xspc 360 Rad > Swifttech 120 rad > Phobya Balance. ( the reason for the additional 120 res after the 360 is I was going to be cooling my GPU in the same loop at a later date ) I have checked every where and made sure the rads etc are clear of blockages and they are.
