AIO watercooling tubes have large different temperatues before and after radiator

[Nesflaten]

Hi all. I have searched for 5-10 minutes on this topic, and have not found the answer. 

 

My system: 680 stock

AOI watercooling: Arctic Cooling Accellero Hybrid

Motherboard: ASUS P8Z77-V deluxe

Ambient temp: 22C

CPU: Intel Core i7-3770K

CPU cooler: Corsair H110

 

 

It is a few years old, and my GPU sometimes peaks at 100C. When I touch the tubes going to the radiator, they are very hot. The tube from the radiator is as cold as when off. the GPU idles at 36C, but a few months ago it idled at 28C. Even at idle, I can fell that there is a temp difference of the tubes. I do not feel a difference on the AIO on the CPU, 

 

What is the usual difference between the tubes? 

 

And if you have a solution for my problem, that would be awesome!

Since the tube that comes from your radiator should be colder (I think because the liquid is just being cooled by the radiator) I don't see a problem there. Maybe there is something holding the flow if the liquid back? I have to be honest to say that I don't have that much experience so maybe another member here can help you further. Good luck though!

I'm pretty sure that is a good thing. It means the liquid is moving the heat and dissipating as it passes through the radiator..

I think it might also be really slow flow speeds, but no way to check it i think

liquid temperatures before an after a radiator are only supposed to be a fraction of a degree

fluid in watercooling loops move so fast that all the liquid is the same temperature

this is why order of components in a loop does not matter

 

if he is noticing a difference between the tubing that means something is seriously wrong, probably lack of water flow

this is NOT supposed to happening, maybe his pump died or something got clogged

Thanks for the info. Total novice to watercooling, and about to take up my first adventure with it in the near future. This info should majorly help!

@Enderman, that sems quite reasonable. I will troubleshoot some more to be a bit more surebefore I change out the watercooling loop:S Might just change the GPU at the same time:P

 

@MblaZe7run: Good uck, you will hopefully not need this info;)

Comes to show how complicated things are. I took the radiator off the case and lowered it below the pump, rised it above the pump and repeated this a few times. Now it idles at 25C

And after a 2 week vacation, the GPU idles at 66 degrees celcius. I think the closed loop as leaked too much liquid. Better buy a new GPU then
