DDC Pump not moving liquid? or faulty gpu block

[Irregardless]

Im having major problems with my watercooling loop, and i am uncertain if it is the pump or simply user error, ive come across a few forum posts with similar problems, but the solutions that mostly have worked fro them have not worked for me. I Tried tilting the build an opening the top port on the res, but all was to no avail. The pump, as described in the video, moves the water once its beign filled the first time and* appears to pump out some air, but then it seems to stop working, Im not sure if something is blocking the flow, but it should not act like this.more details in the video*https://drive.google.com/file/d/1q3IpEw_ybBcRzqqf56ZVfWWHrg2RfWRB/view?usp=sharing

*i tested the pump outside of the unit with two radiators* in the loop without the cpu block. it did fill the radiatior but i am not sure if it is workin properly.* there is apparently issues with the pump and /or the cpu block
here are some more videos that i urge you guys to watch. Any help is appreciated

I see nothing wrong.

It looks like you need to fill your res up. In the last vid you can tell by the sound that its pumping alot of air due to a lack of fluid in the res(this will kill the pump). Eventually the air will lock the pump up.
Thats why your temps are bad and the reason why the back of the pump is hot. It needs water to keep itself cool. Top it off and you should be gtg.
Also try to keep the res level so its not allowing air into the loop.

how are the gpu temps at 90 degrees then? the liquid is flowing very slowly as well

You can open the GPU water block and see if that is the problem. Not sure how old the block is, but there could be gunk built up. Also not sure how old the pump is, as with age they will eventually stop working.
I would remove the pump and GPU from the system. With just the pump and GPU block, I would fill and run the setup. With the pump full of water, I would tilt the GPU block back and forth. This may clean the blockage.
Do your test (https://drive.google.com/open?id=0B7...lBSTY1WVgybVFV) but replace the CPU block with the GPU block. Let us know how this works

^ What kind of coolant have you been running in your system?? When was the last time you did maintenance on your water loop???
^ BE WARNED - Opening the block will void it's warranty. When you reseal the block - DO NOT over tighten the screws as this will crack the block. <- Do this as a last resort. After resealing - run the block for 1 hour to verify there is no leakage.

- From the 1st Avengers Movie - Tony Stark - I can't do the equation unless I have all the variables.

Thank You For Your Time

i got this gpu on polish ebay, the waterblock is only 1 year old. when i got i, i disassembled the waterblock and the gpu and flushed it like i did all the radiators with the solution of vinegar and water, there was virutally no gunk. the gpu waterblock has no leakage and the coolant flows through it. ut it seems to flow very feebly. im not sure if thats the issue with thermal paste or what, but it just doesnt seem to cool the gpu. . THE LOOP IS 1 WEEK OLD. got it on aquatuning.co.uk literally on 8th of august, and olny installed it on 18th theres a video of 2 rads gpu amd cpu in loop. and of only gpu and two rads -

Could the pump be a DC-LT? In temps of how its moving water it looks more like a DC-LT then a DDC in terms of how its moving water.

no. its ddc 100%
