Was playing Battlefield 4 tonight, when my system turned off, and rebooting with a POST message saying:

"CPU Over Temperature Error"

First time I have ever seen that, and usually my CPU never gets higher then 50. I took my headphones off and noticed that my system seems a bit quieter, no pump noise really. Turned off the system. Let it sit for a bit, turn it back on, and noticed my GPU temp got to 50c on boot, it doesn't even hit 40c in games. Stuff seems to be fine now though at idle, GPU temp is 26c (still a bit high) CPU at about 23c (which is normal). I have noticed that lately my pump has been acting funny, but it is hard to tell that it is actually working now.

The what? Sounds like a Skyrim reference..........
then you go here and get your new pump.
you can test your current pump. but in any case you'll have to disconnect loop :(

Do you have a flow monitor? That's the best way to tell if your pump is giving up, aside from checking your usual idle and load temperatures.


I'd use vodka redbull directly injected into the loop compared to a resurrection scroll btw.

Think I'm thread stalking you. Normally it's RCoon who I seem to shadow.

I use a Primochill flow monitor (http://www.amazon.com/dp/B00DLUX0QW/?tag=tec06d-20) - for this exact reason, I'll know when my pump stops squirting and my PC needs a trip to the Laing D5 Viagra clinic

This is also a valid reason to employ quick disconnects before and after the pump unit!

EDIT: Stick your hand on the pump. If you can't feel a gentle hum, the pump is dead. Usually before a pump dies it makes a terrible grinding noise.

Yeah I switched almost all of my fittings to quick disconnects, this way I can detach pump, res , GPUs, CPU and motherboard without emptying the loop.

I never have to refill the loop, even when I switch out major components.

That's one of the reasons I don't use a case :)

It's a bit costly though, quick disconnects are expensive.

problem is that he already missed hell of a noise moment and now even touching it he wont make any difference if he hasnt touched it while it was working.

So going to bump this thread back up instead of making a new one. There must be a problem with this pump or the way I have it connected to the PSU, as itll have trouble either starting up (ill hear it click) or when it does it makes a audible high pitch screech noise, and when it is running, sometimes itll just turn off, like its not getting enough power. I have it connected to the PSU with a 3 pin to 4 pin molex connection. Been thinking about just getting a brand new MCP350 from PPCS that come default with just the 4 pin molex connection, rather then 3 pin.

Your connection should be good since the 3pin and the molex have max 12V!

Ever pull the top off the pump? And I assume its a 350 mpc. I had a problem with the power and turned out that when the power was plugged into the molex it would sorta pugh out the pin from the housing it self. I just pushed it in with atiny screw driver and never nad an issue sense. Id take the pump head apart and pull the iimpeller out and clean it up. I had a tiny clicking noise that pissed me off and what I found was a tiny piece of metal from a thread probably from production. Anyway the impeller being magnetic attract and sliver of metal and hey ya never know. ;)

the pump itself is two parts. mechanical and electronic motor.
mechanical part wont fail... its an impeller. but electronics will definitely fail.

more likely for the coil to fail. sudden load can cause too much current through and fail.

even if bearing fails, it would turn. unless bearing is made of plastic.

If the new on has the 3 pin connector with single wire for RPM monitor from mobo fan port then use it.

I have thought about using a Raven RFM15 a few times in mine, but don't know where it would fit in the case, the PWM header would read the sensor output.

funny, my pump just died too. it was a combo res with pump inside. turned on my system friday and noticed overheating, then pump not pumping.

got a new mcp665-b, no res, and can't seem to get water to go through cpu block. took it off and washed it out don't see any blockage.

very annoying process so far.
