How loud are water pumps??

The D5 is extremely quiet. Not 120mm Yate Loon Quiet, but not far off.

No idea about the Reserator - never used it, and not really a comparison in terms of performance / capacity.
 
I've only ever used an eheim 1250, back in the day. It was audible back then, but very quiet. Whether that was because I was coming from a copper hedgehog + 60/80mm delta or because it was actually very quiet.

I take it the more modern pumps are much quieter than the old eheims? are they also more powerful?
 
The reserator one is silent if that helps

I have a V2 on a second system and its been running 24/7 for nearly 2 years and ive never heard it.
 
odd comparison... the reserator won't cool your pc and the D5 is towards the top of the range, you could look at a DDC 10w or ultra?
 
I couldn't hear my DDC Ultra (ddc2) + Alphacool top at all over the sound of my power supply in my Akasa Eclipse (known as not the quietest of cases) - psu is a Enermax Liberty 620W.
 
thanks for all of your comments so far.

The reason I made the 'comparison' is because I ultimately want to effectively cool my system, but at the same time reduce noise levels to an absolute minimum.

Therefore I was thinking an internal H2O solution for my 2 x 8800 GTXs, and an external solution for my MB and CPU.
The reasons - my CPU and MB generally stay a lot lot cooler at idle and stress levels than my GPUs do. Therefore I reckon I can get away with a passive H20 solution with my CPU and MB?
 
Passive on a QX9650 is a MASSIVE waste of money. With regards to the fact that temps will be rubbish, and why go for an unlocked top end CPU if you arn't going to overclock it...

I have overclocked it - just not massively yet (3.5GHz) - as i haven't got the time currently to get a good OC on it - will try to get 4GHz this summer.

Basically I want to stop my Zalman CNPS9700-NT revving up constantly when the CPU usage goes from 0-5% to 20->% cos it sounds annoying!

The whole H2O cooling thing is more to do with noise levels than temperatures. (although with regards to the GPU's, it's to do with both)

All idle:
My QX9650 @ 3.5GHz is running at 33/26/33/33 (yes 26 - dunno why it's so low?)
MY GPU1 : 57
MY GPU2 : 59

5 mins prime blend
QX9650 @ 47/43/46/47
 
gfx cards are always hotter than CPUs but temps are normally a much less limiting factor for stability/clocking.

Plus they react incredibly well to watercooling as stock heatsinks are cack, for example even in a multi block loop my 8800GTX is currently idling at 36 and loads at about 50ish.

However CPUs are much more temp sensitive and 5 mins of prime load has taken your CPU nowhere near its full temperature, also with passive water there is no airflow to remove the heat, you're just relying on convection so the heat buildup would be huge, I would imagine you could overwhelm a passive setup in no time with a QX cpu, especially if you chuck the mobo in there too, it would be too much for it.

Passive watercooling is a low heat output/stock/underclocked cpus for total silence, not for hardcore extreme CPUs.
 
If you want silence it's important to buy proper water-cooling not some dodgy external rubbish. You need cooling capacity which hugely exceeds your heat output so that you can use minimal fans to cool it all. Get a 120.3 radiator, preferably from Thermochill, and use Yate Loons. Get a small pump like a DB-1 and a low-flow block like the new XSPC with a T-line rather than a reservoir as T-lines are completely silent whereas reservoirs can suffer from whirlpool noise. Radiator on the roof of the case. Then do another similar loop for the gpus with the rad inside.

Yeah I coming round to that idea too.

I am just wondering how I will watercool all my components, and fit all of the equipment in my Coolermaster RC-1000.

I guess I can fit a dual rad at the top of the case.
A res and pump in the 5.25" bays.
but where can I put another rad - cos i'll need a dual loop?

thanks
 
Motherboard (if you really must although I wouldn't) and cpu on the bigger rad. GPUs on the smaller one as they need much less cooling.

ok.

my mobo - striker II extreme has a factory fitted water block/heat sink cobo on it. (uses 1/4" fittings) So should I water cool it anyway - would this prolong its life to some degree, etc etc

I find it funny that the CPU needs more cooling? But hey, i'm new to this.
 
If you've got a pre-fitted block it does seem pointless not to use it. an overclocked, overvolted cpu can generate serious heat. Secondly, it's highly focussed; generally the size of gpu dies is greater than cpus.

But it does all rather depend on what you're doing with your computer. I don't game but I run the cpus at 100% 24/7 because I fold so I only water-cool my cpus. Some games are way more intensive on the gpu than cpu in which case having a 4GHz QX9650 is a complete waste of effort. Many people spend way too much money on components they don't need. Is your 4GHz quad necessary? Would a 2GHz dual be just as good? Will it be run at load for any length of time? If yes, but only when a noisy game is running, why bother with water-cooling as you will only be able to hear the game. If you're video-encoding, are you time-limited; i.e. it must be finished in 23 seconds or would four hours be perfectly OK?

If it's just because you've got the money to do it, have you thought of buying your Mum some flowers instead?
 
well I have to say that having a 4GHz amazing CPU has got to be better at playing these latest games, for instance Crysis, as much as any other application. The CPU workload in the games is increasing all of the time. So in terms of future proof'ness, (as much as that can be used!), my QX9650 has got last longer than a Q6600 and then Q9xxx for instance.

Folding imho is a bit of a waste of time/ electricity/ money. Ultimately the people who do it 'could' help in the medical/other world I agree, but unless you really really feeling strongly about this cause, is it worth spending £1,000's on components and £100's on electricity each year? In my opionion - no.

I bought the components I did because I wanted the best system I could get for a 'resonable' price. The reason for the best components - best FPS in games, quick loading times all round, quick video encoding, anything else that requires a quick pc!!

Why am I considering a water cooled system?
Noise levels
I have:
5 x 120mm Fans
1 x Zalman CNPS9700-NT
1 x Cool spot
2 x stock GPU coolers
9 FANS!!!!:eek::eek::eek:
Crazy I think you'll agree. I NEED to cut down!
Cutting down on some of the 120mm fans or the cool spot won't help my temps as I have found. Therefore I have to keep all of those fans in there until I come up with a solution to replace them. My PC is quite quiet for a PC with 9 fans in it, but its still too loud for me.

you seem grumpy Mike, is it that time of the month? ;)

anyway I think you're missing the point, people who buy extreme edition CPUs fall into 3 camps.. extreme clockers who need the cooling for benching runs, hardcore gamers who prolonged load who want decent clocking and cooling and finally people who've bought the fastest CPU they can regardless of cost and have no idea about clocking and almost certainly don't require or access anything like the power they have.

Only the last one would benefit from a downgrade and no water but I don't think this chap falls into that camp.

@ the OP

you don't NEED a dual loop, a thermochill PA120.3 rad hung off the back of your case would be more than adequate to cool your 8800GTX sli, QX and mobo.

Just give up on the reserator.
