Bad First Water Cooling Experience(Turned Good!)

post #1 of 22
Thread Starter 
When I bought the system in my sig I knew I wanted to water cool it but didn't expect it to be such a hassle. I decided on just a heatkiller with a xspc rx360 rad to get an idea for the concept. My problem was what to use for a pump. I saw that xspc made a res/pump combo and figured it would be perfect for now; it is cheap enough so that I could replace it with a better res and pump if I wanted to go "all the way" with water cooling down the road. This would be the 2nd Noob mistake I made as the first was not asking on this forum.

So anyway, I get it all hooked up and get a mild overclock of 3.8 @1.275v just to get an idea of what I get to work with. One of the cores temps almost hit 70c at load. After throwing a short temper tantrum (Flyers lost the Stanley Cup so I was moody) I soon came to realize mistake #3. I did not apply my tx3 properly, I made a horizontal line instead of spreading it with a credit card. After I got that taken care of, I noticed the rad still had some air inside it so I jumped the power supply and tried to work it out. This was when I noticed that in fact the problem was the pump.


In this picture you can get an idea of whats going on. The pump outlet is extended to the res outlet by about a 1/4" tube. I don't know how they connected it but its not working. The pump is just shooting the water around in the res and very little of it is actually making it through the loop.



Some pics of temps. Ambient is 31c. Using ripbot264 for load temps.




My question now is, what pump and res should I get lol.

As for the reservoir, it depends on if you want a bay res or not and how much you're looking to spend. Here are a few.

Here is your problem.

Flow Rate: 200 Liters per Hour
Also maybe try to reseat your block.

I thought the same things. I did reseat the block and did get a few degrees out of it but the temps still don't seem right. I figured 200 l/ph would be adequate for a heatkiller single loop w a 360 rad. The rad overkill should cover it. But after all that swag thinking (scientific wise ass guessing) flow is the problem here. You can actually see where the water hits and goes as it travels through by looking at the temps. Not to mention I can see the pump leaking inside the res and there isn't anything I can do about it

The better choice would have been the xspc 750 combo but........don't knock xspc they make some quality stuff. You also got one of the most restrictive blocks on the market too. Xspc is designed for low restriction systems. Water cooling is like anything thing else, there is some trial and error. Don't be so hard on yourself. If the pump is bad return it and keep on going. Machinery fails like anything else. It will all be ok. Breathe in Breathe out.

Not trying to knock xspc, I love the rx360 I got, it's just I feel that their single bay combo is a bad design. The pump can actually suck in air if the res is not filled to the top, and has the tendency to suck air coming into the res ..although it might have to do with the leak. The 750 looks better for sure, but I don't want to use 2 bay drives cause I wouldn't have anymore left.

Lol I will try to take it easy, but my ocd won't like it. Im just going to end up keeping the combo and fixing the leak with sealant. I agree that the heatkiller isnt helping but I figured from reading this, that I would be ok at around 1 gpm. Trial and Error, just like you said. Thanks man.

that pump res combo would be fine if it was working ok i had its bigger brother and i thought it was not that good so i swapped it for a mcp355 and the temps only dropped buy 2c.will a cpu loop it will be ok its when you start to ad a mobo or graphic card you need a better pump

Hopefully I can fix it, and spend the money towards a new video card so I can get a 2nd loop going w/ mobo and graphics.

Quick question. What do you guys think of setting up rads like this. Not looking for the best temps.
