PUMP header randomly died

[TheLUCKYfighter]

Hey there,

 

So I built a new gaming rig 4 weeks back and used (for the first time) an AIO. Upon receiving this 'new' AIO there were immediately some problems with it. For example, it came with no thermal paste (should have been pre-applied even) and there were some screws missing. Anyhow, I sorted this out with my seller and continued building. Next thing that happend was that the AIO sounded much more loud that seemed normal to me, this made me even more doubtful than I already was. However, after doing all kinds of (stress)testing everything seemed normal except for the noise. I played flawlessly for around 3 weeks until suddenly my PC shuts down due to overheating. I was very confused at this point and quickly pin pointed the problem to the pump of the AIO, which didn't seem to respond anymore. After all that happend, I simply returned it and got a new one. 

 

Now comes the interesting part though. Today I installed this new AIO but noticed the EXACT same problem (pump not responding, but fans spinning). Luckily however, no more missing scews or thermal paste. I had my fans and my pump seperatly connected, pump to the PUMP header and fans to the CPU header. As such, I tried to connect my PUMP to the CPU header to see if that changed anything. To my suprise, this fixed the problem. 

 

So it seems like my PUMP header randomly died while gaming? Is this even possible? Could a malfunctioning AIO cause such a thing? There is no visible damage. 

 

I do not plan to RMA the MOBO (although maybe I should) for multiple reasons. For one, it would mean I have to take apart my PC again in a drastic way and remain without a PC for some time. My AIO is actually intended to be used this way (variable pump speed) and the sound is now MUCH better with this new one (I changed it to constant earlier to reduce sound). Sadly, even if I was prepared to RMA, I bent one (uninportant) pin on it and heard they often don't accept an RMA if this is the case. However, maybe someone here has an explaination to what could have happend. Maybe even a fix.

When the pump died, it popped the fuse on the mainboard. 

 

Only option is to RMA the board or solder a new fuse in, I suggest the first option though..... it's actually a lot easier.

Could I just leave it like it is and stay with the CPU header for everything? Or might that bring more problems in the future?

Don't run AIO pump on the Cpu header, you'll loose that one too.... grab a molex to fan adapter or something instead. They suck, but it's a better option for the amp requirement of the pump. plus the PSU will just shut off via the protection if the pump shits it's self again. Which is likely and the nature of cheap pumps.

It's a Fractal Celsius+ S24 so it should normally not be that cheap quality. Why would I lose the pump when connecting it to the CPU header? The way Fractal instructs installing this AIO in the manual is to connect all fans/pump to the fan hub it comes with, and then connect that one to the CPU header. You should expect this to not be a problem in itself if it's in the official instructions, right?

When a motor shorts, it does what to a fuse? (that's just how I think about electronics....)

 

But really, it is a cheap pump. The Swiftec MCP 655 it's self cost almost as much as your entire AIO for example.

I think my main question is, assuming the pump will work correctly from now on, is there any remaining danger or significant negative to not RMA'ing the board and just ignoring the broken PUMP header?

Probably not. It "should" be fine, but for what amount of time, no idea my friend. Some AIO last years and years, some crap out in just days to weeks.
