I have a pump/res combo with a Laing D5, pwm set to 60%. It goes to the 360mm reservoir first, mainly because of space constraints, but it's nice to get that bout of cooling right before the CPU. From the CPU to the 120mm Rad and then to the GPU, which is as effective space-wise as I can think of.

I can tell you 35C is THE highest temperature I've seen on my GTX 670 which tells me flow rate is sufficient. I have my CPU in the high 70's now running two cores of stress test.

I'm just talking out of my ass here, as I've never done water cooling. Jerry and LaurV et al will be much more informed and informative.

But is there any chance your pumps are fighting each other?

And/or, could your pumps be fighting to get past an "air bubble" trapped in the lines? Your diagram didn't clearly show the relative heights of each device.

I appreciate your help. The number of times I've been ignored for "not being knowledgeable enough" when common sense was enough... There is only one pump, so that won't be a problem, and I know it's providing enough flow as all the water cooling the GPU must necessarily be passing through the CPU block.

However, I will investigate the possibility of air in the CPU block. I doubt there's a significant air buildup in there, but it's possible the bubble is forcing water away from the critical area immediately above the core.

Default BSOD's

Well, the problems aren't stopping. Since setting up my watercooling, I've been getting a pretty bad number of BSOD's doing all various sorts of things; playing a round of League of Legends, watching a twitch stream, twice when restarting my computer, once when just looking at my desktop... etc.


I've started a memtest86+ test but that takes a while. I'm going to let the first test finish and then try other things because while this is going on, I can't do anything else. I thought I would start here and see if any good ideas come about.


So far, the BSOD's I can remember are:

Page Fault in Nonpaged Area
Bad Pool Caller
Bad Pool Header


Apparently there's somewhere else I can go to find more details. I'll probably end up posting in a few places because I know this forum isn't exactly tech support.

Of the places I've visited where people have had similar issues, one person fixed it by changing their RAM. I've tested mine extensively in the past and nothing has come up before. I'm working on this now.

A lot of people point toward the power supply as a common source of problems, but I've added five fans, removed three, and added one pump. Before the BSOD's I was running mfaktc on two GPUs, so power sounds okay.

One person fixed their problem by changing the motherboard and I really really don't want this to be the solution to my problem. I don't know how to determine if the motherboard is the culprit.


I think my next order of business is to start checking my hard drives. I have an image of my SSD from maybe December. I usually keep it more up to date but a program on my secondary drive considers itself a service so I can't only image my SSD anymore, and I haven't had the time to deal with that. Most of my data is on dropbox or backed up or both, so I COULD re-image my SSD but I would also rather not.


Because my CPU waterblock is misbehaving I've been trying to clock my CPU down a bit (and the first BSOD I had encouraged me to bring my voltage up a few steps, too) but I actually can't change my overclock settings. When I set my clock speed in my BIOS to 4.4 GHz instead of 4.6 GHz, it's back to 4.6 GHz by the time I'm into windows and opening CPU-Z. I've re-installed the overclocking software that came with my motherboard (ASUS AI Suite II) and I think it is somehow the culprit as it is very insistent on 4.6 GHz also.

Sadly, since I've started trying to work on that, I haven't had a successful shutdown, so maybe the software thinks my new (lower) overclock is unstable and it reverts to the last stable (higher) one.

This is a good reference for BSOD's with details for each Bug Check code and parameter:

The three you listed appear to be related to memory so maybe memtest86+ will provide clues.

Look into if your are overloading your PSU's "rails".

Thanks for the reference. I'll keep a log of the BSOD's I get and I'll cross-check them.

The PSU has a single 12V rail. Thanks for your continued help, though, Chris. Much appreciated.

You might be surprised...

I thought a machine I was in control of only had a single 12V rail, but instead it had several different 12V rails. This actually protected me from myself.

I can't find the thread at the moment, but by simply switching the power feeds (as suggested by another Forum participant) solved the problem at hand.

Did you actually "check" the PSU label before that?

AI Suite gets some pretty harsh evaluations over on the Asus and ROG fora. I used II for a long time on an older Asus AMD board. My current Crosshair V Formula-Z came with AI Suite III, which turned out to be a great disappointment. Its graphical elements (system monitor) were not as configurable as in the old version. It also seems to have caused considerable instability. Things got a lot better for the box when I fully eradicated AI Suite. Look on the ROG forum. There is an AI Suite cleaner app, at least for some boards and versions of the software. The normal uninstall leaves considerable garbage behind.

Try doing your OC from the BIOS.

The problem I'm having is that the BIOS OC is overrided by whatever the fuck AI Suite II wants, even after I've uninstalled it. Granted I uninstalled it the normal way. I'm going to check that thread out now.

EDIT: Currently my BIOS is set to 4.4 GHz with a slight bump in voltage in an effort to stabilize. OS (or whatever) defaults to the original voltage and 4.6 GHz, which I've been doing for ages.
