Problem with CPU Liquid Cooling

Ok so im trying to figure out a problem, I've cleaned out the radiator ducts, refilled my resevoir with bi-distilled water with an anti-corrosion addative, and make sure all pipes and screws are snug and tight.

The problem I am having is with the pump above the cpu, it is making a very large amount of noise. It's never made it before, it is constant, and at a steady, fast pulse. It actually sounds pretty much like a cpu fan, it sounds mechanical. Before you ask, I have no idea the brand or model of my liquid cooling system, it was the generic from ibuypower.com. Can anyone tell me if this is a problem that will lead to overheating etc, cuz if so I need to turn it off sooner than later.

 

The CPU is the Athlon II X2 240 processor. It's a AM2 or Am3 (whichever is dual/quad core) 2.8 Ghz, and is not overclocked. As for a temp gauge I dont have one but the Core Temp application that comes with Windows 7 is saying that it is averaging between 25 and 26 deg C.

I do not have clear pipes so I dont know about any bubbles, however I did clean it using vinegar and used a new fish tank air pump to continuously pump the water through into a container to agitate and clean. I then used the pump to re-rinse for 30 mins, changing the water once every 10 minutes. After that I refilled with with bi-distilled water and an anti-corrosive additive. To be honest I have no idea how much of that was neccessary vs how much of that was frill, but I feel pretty confident that it is clean enough, and free of air, debris, or algae.

 

The sound isn't metallic, it honestly sounds more like a case fan when its slightly out of sync, and it didn't make this sound until after I cleaned it.

I went ahead and took it back out and routed power to it from some portable IT tools I collected over the years, and just held it in my hand, and the vibration is DEFINITELY coming from the pump. It does it when I'm holding the pump in hand and its not even touching the CPU.

So to the final question I guess. If it is the pump, but the temp is good, should I bother fixing something that isn't broke? I mean I wouldn't take an old car in for repairs over a few rattles unless a warning light came on.

 

Ya, I agree. Let your car run until there's no more oil left and your engine seizes for some odd reason!rolleyes:-D Seriously, you changed something in there or the issue manifested itself when you changed the water. Either way, if the pump goes I hope your CPU thermally shuts down before it blows up.

Off topic question if I may. Water cooling on a stock speed X2? It is nice but a total waste IMHO. Get a nice, compact Corsair H50 instead, water cooling without all the headaches.

 

well the idea behind the water cooling was to later upgrade to a quad core and oc that. the site i bought it from wanted like 50 bucks to do something i could do myself from bios. Im just not sweating it until I buy the upgrade.

 

Plus I'm pretty sure that low oil pressure or hot oil would give me a warning light...hence the statement following my "unless." Thanks for the total lack of contribution though.

 

Yeah - I know it's an old thread, but I had to comment on this:

Kind of rude, no? augie is a long time and respected member here at MG, and did post something VERY helpful IMO:

This is EXTREMELY helpful considering the OPs situation. Old-school "traditional" water cooling is more-or-less obsolete and unnecessary, even if planning to OC anewer quad/hexa/octa-core CPU, and especially on a stock AthlonII dual core CPU (the stock air cooler is sufficient for stock clocks). The newer high end air coolers are AMAZING, and the enclosed liquid coolers like the H50 or H70 are excellent and completely trouble free.

I think it was an important contribution even if it was a bit off topic.

So there! :neener

 

You're welcome and it was my pleasure to help.

Ya, I tend to do that at times.:-o Thanks for watching my six.

 

There's your problem the pump should be at the bottom of the case,it should be at the lowest in the circuit.

The reason for this is simple pumps can pump well but they can't suck well it puts a huge amount of strain on the motor.

You may get away with just moving the pump to the bottom of the case now but it does sound like you've burned out your pump,unless I'm misunderstanding and the pump is built into the cpu block or similar,in which case move your radiator above the pump.

 

After many years of building PC's using the AMD cpu's, I've found that they run much cooler than their Intel equivalents and the cooler that comes with them in the retail box is more than sufficient to keep them cool. My own AMD, 2X, 5200+ cpu with the stock cooler runs at little more than room temperature, even under the heaviest loads.
(I do take is all apart and give it a good cleaning, once a year)
I can lay my finger on the heat-sink any time and it's only slightly warm to the touch.
I'd NEVER put water inside my PC. That seems like a sure-fire recipe for disaster.

Just a thought from an old PC builder,
