Hi there guys.

I've been running a leak test on my water cooling loop for 6 hours. There are no leaks so far but it is very warm. It's so warm that it would be incapable of cooling my AMD 9590 CPU. I'm using an 'Alphacool NexXxoS Cool Answer 120 D5/UT - Set' with a 'Magicool 1/4" Thread Inline Watercooling Filter'. The D5 pump is set to max speed (5/5).

The only thing receiving power is the pump itself and the PSU, of course, as it is a leak test. The loop is inside the case and is set up the way I would set it up when my PC is up an running.

The entire loop is very warm from the radiator to the reservoir. Are there any ideas of what could be causing this? Many thanks in advance.
 
Solution
As others mentioned, the pump will cause heat. That's what helps keep the pump cool, the cooling loop that it's a part of. The coolant will be no less than ambient room temps and without radiator fans connected to remove the heat generated by the pump it's not abnormal for there to be heat building up. Using a filter of any kind is going to restrict flow which places some additional stress on the pump. That too would likely cause heat to build.

Running a pump 'dry' or with air trapped in the system causing a dry pocket around the pump internally will cause it to burn up from lack of proper cooling. Without radiator fans running to actively cool it, you essentially have a large tub of heated water. The only real cooling capacity of a...


I wasn't ignoring the obvious. I down voted him because his response didn't acknowledge the comments that came before his. Earlier, he was trying to explain to that what I was doing was a leak test and it had nothing to do with temperature which showed he missed to point of this thread, even though I'm sure he gets it now.
 


It's okay, I do understand what the others have said. I just don't need guys like USAFRet telling me I'm just running a leak test and that it has nothing to do with temperature, it's not rocket science, or explaining to me how water cooling works. People before him already suggested that it could be the pump and I acknowledged that with my responses. That's why I felt he was trolling.
 


I'll tell you what. If you had genuine intentions I'll assume I took some of what you said the wrong way. If it is on me, I apologise. No point being negative. We're all grown ups here.
 
No, you didn't "acknowledge" it with your responses. What you did was refute it with your responses, or indicate it was irrelevant to what you were trying to do, which it's not. It's the ONLY thing that's relevant.

And just for the record, that "guy" USAFRet, that moderator, has forgotten more about computers than you are ever likely to learn, so it might not be a bad idea to listen when somebody with extensive experience is trying to help you see the issue by verifying what others have also already indicated.

And we consider being called "trolls" as highly insulting, so you might consider whether that's the best way to respond to other members unless it actually applies.
 
Thanks again for your help guys. I did what I suggested earlier by lowering the speed of the pump for the time being. I was able to run the pump for an additional 14 hours without the original heat issues. You seem to have confirmed my suspicions that the filter was a factor in the issue as it was the warmest part of the loop. I'll let you know in the future how I get on. Suggestions are still welcome.
 


I do listen. That's why I started this thread in the first place. I respect the fact you're defending a fellow moderator but I guess we'll just have to agree to disagree on this little issue and get back to the original issue.
 
There's no disagreement. I'm simply saying he was right, as were others, and you wanted to talk about something else, as many members tend to do. But either way, hope you eventually get your issue resolved. For me, I'd disassemble the system, throw the filter away, clean everything twice, reassemble it and move on.

Chances are that you've run it plenty long to filter out anything that was going to be filtered out. If you still have "stuff" in there after further cleanings, then something is wrong with something because there shouldn't be.
 


For the record, I've stayed on the issue I've raised throughout until this little dispute came along. However, thanks for your advice you've given on this thread.
