Question CPU Pump for a whole system?

[Koroxid]

hello there,
i am currently switching my air cooled system to a liquid cooled one. i got an eisbear cpu cooler+ reservoir + pump combo with a 420mm radiator that my friend gave me. however the pump wasnt in use for a long time and tryed it on my build (cleaned it before). i extended the loop with a liquid cooled gpu but i am not sure if the cpu pump have enough power to keep the water running. after booted in windows, i checked the cpu temps and noticed that the they jump alot (betweend like 35-50 degrees celsius) in idle already, after i started a game the temps instantly jumped to 80 and after a few minutes it was 94. the tubes around the pump were relatively hot and i think that the water isnt flowing (at least not very much). the bios says the pump is running at 3000 rpm. just wanna add that the pump is already 180 degrees rotated and the reservoir is completly filled by now
here is the image

It isn't particularly clear did you try the liquid cooled setup with just the CPU before adding the GPU block in?

Is the fluid clear? The window looks opaque and Alphacool specifically cites only using clear fluid in those.

It's also supposed to be a 2600 RPM pump from what documentation I saw that seems to match the style you have. Since Alphacool's documentation is lacking I can't tell for sure, but I'm assuming you have in/out correctly hooked up?

yes i did try it without the gpu before and the water was running i guess but since i am not entirely sure, so i want to try it later again. the fluid is a coolant from ekwb its called ek cryofuel mystic fog premix, but it flows like normal water. the pump is running at 2600 rpm i guess but the bios says something around 2800-3000 and the tubes are correctly set up

You should definitely try it with just the CPU to make sure that the pump is working. If it is working there then it likely is a situation where the pump doesn't have enough pressure to push the liquid through the loop with the GPU. The tubes do seem a bit long for the pump only having 1m maximum head, but I'm not sure cutting length there would be enough to get it working as the rad is also pretty big.

Ty for your Help. i tryed quite a few things by now. i put in only the small loop, checked for air in the system and checked if the tubes are correctly installed. Nothing really seems to help so i ordered the exact same CPU cooler and see if that will run better, otherwise i still have a big Pump that should fix that

Certainly sounds like it's faulty then, good luck with the replacement!
