Flow Rate Query

[Hood]

No changes in sound or temps.

same reading from the MB or a fan controller.

flashing light seems ot be the same, same as the spinny thing (mines a clear type)

rpm of the pumps are not changing.

Think i was better off not knowing lol

Wait till it spikes again and you still have no idea what it is doing.

Well yesterday and this morning back to 2.4LPM.

Both pumps have been reading about 4400-4700RPM. No noise other than the usual whine after the first 30 seconds or so of running.

I'm planning to pull out the multimeter tonight as Creakin suggested and see what is being reported without the amplifier. For what it's worth the green light on the amplifier does appear to flash slightly slower now than it did on Saturday when reporting 3.3LPM.

Well I finally got my act together last night and took (almost) everybody's advice on here...

I've removed all the QDCs and one of the 560 rads. After bleeding the loop I got....wait for it.... 5 Litres/Min!!!

I didn't have enough time to check temps (it was 1am when I switched off) but it will be interesting to see what the overall effect is.

Might try adding in the second rad again on the weekend to see what (if any) effect there is on the loop temps and flow rates.

I guess that Creekin was right - friends don't let friends buy QDCs.

I know a few guys on the WWW have done flow-testing on them, again, it also depends what pumps you are using - if not needed, get rid of them, and you should see 5-7lpm with that setup of yours.

So, I am happy that your flows are in the predicted window - you can put the rad back, won't be causing much of a restriction. Now, if you really need to have it there in the first place is another story.

Enjoy your new-found flow.

At this stage unless temps are an issue I'll probably leave the second rad off. Scary how badly flow rate was affected by the QDCs.

Current plan now is to try to mount the rad on rear of the case somehow, probably with some sort of standoff brackets and platform attached to the bottom. At least that's the theory but we'll have to see how it flows...

you could make some diy qdcs- old school styles 2 sets of:

2 of these : http://www.pccasegear.com/index.php?...ducts_id=19002 with one of these in the middle http://www.pccasegear.com/index.php?...ducts_id=16319

Should be less restriction as the are just fittings - not impeding in the flow of water.

yeah i just use taps instead if at all
dont even need the d plug really...how "quickly" do u need to strip ur loop?
not an f1 pitstop remember

its just alot simpler and easier in the long run to drain the whole loop and work on it "dry" IMHO

Are you sure the flow sensor isn't actually busted? I know it's easy to believe it's all working perfectly when you start getting good results but the fact is that it's been fluctuating like crazy, with and without the QDCs. I'd want to test it to make sure. If they're only $20, just grab another (although it it means draining the loop I completely understand why you'd want to stick with what you've got).

Also, am I mistaken or do you have the tubing back-to-front on the CPU block? From memory, the lower socket is 'in' and the upper is 'out' but it looks like you've got it the other way around (unless you've rotated the CPU block).

I might next time I order some stuff just for the heck of it, but I want to see if temps are higher or lower than what I was getting beforehand.

You are correct that 'in' is the lower socket and 'out' is the upper. I've got the loop's water flow going through the radiator and GPUs first before the CPU then back to the reservoir, so is all correct.
