XSPC RX 120.4 Radiator heat dissapation

Well currently I have a Corsair TX650 I think. Is that no good? Regarding the case I completly agree hence still looking for case but cant find sumin i like.

Ok so if I use some of those gentle typhoons at low RPM, how many rads will be enough to run my gear and keep it dead quiet? dual/triple/quad on the xspc rx 120 series? They are fat as hell
 
Your psu is fine and I wouldn;t change it yet. I was just pointing out that if you get rid of your watercooling fans and case fans then your psu may well become the loudest thing!

But it may be okay as you are a long way short of using all your psu's power.
 
I run a AMD1090t (not overclocked, long story why grrrr) and 2x GTX 260-Core216's overclocked to 700mhz on the core. I cool the CPU & both GPU's on a triple rad with Gentle Typhoons & load temps never go above 55C for GPU's & 50C for the CPU

Reason I will buy a fanless PSU next time. Pumps with a top + foam are silent to my ears, can't hear them.

I still wouldn't, always best to have cooling on the psu when needed.

Take this Corsair AX850 for example.

The fan doesn't even start spinning until 475W load. So you can have a silent system when your pc isn;t under massive load and a bearly audible fan going when needed.

I have always found fanless psu's make too much of a compromise but you can get away with one if your system is low power.
 
The better fanless psu's like mine are actually 800w server grade units that are badged at 550w.
Up to 400w it doesn't need a fan anyway - and 400-550w the case acts as a MASSIVE heatsink.
Also the unit I have has an extra lead - this directly powers a fan (your your choice) when the unit get toasty.

Best of both worlds as it don't void your warrenty if you want a quality psu fan.

The only down side is the cost :( and it's not as efficent as the very newest gold 80plus standard.
If i was to buy a psu now - i'd get one of the gold standard semifanless models like the seasonic X as it's already got as san ace in it :)

That does seem to be the major obstacle with decent fanless psu - cost!

And I beleive the corsair is just a seasonic with a corsair box on as well.

But there are plenty of decent high end psu's now with fans which don't get used at all until you are drawing around 500W.

That's why I always went overkill on my psu power - I found that getting say a 1000W psu when you only had a 500W draw meant almost silent psu operation as the fan would be running so slowly, you wouldn't notice it.

Even easier to acheive with the new modern psu's which have the fans switched off until needed.

I'd also go for this if buying a new psu.

The same principle can surely be applied to the radiator, i.e. fans off below a certain water temperature then turning on at another. Say, turns on above 45c, then off when the water falls below 40c. Fan rpm proportional to temp while running obviously prefered.

I don't know of an off-the-shelf product which will do this however.

There is and has been for a while but not cheap but they are very good.

Look at the mCubed range of controllers. ocuk sell one of the range. Many more models available if you look at their website.

http://www.overclockers.co.uk/showproduct.php?prodid=BB-005-MU&groupid=701&catid=57&subcat=189

monitors 8 anolgue sensors, 8 digital and 2 flowmeters.

All set up with software in windows. Fan profiles for each fan responding to temp.

The controllers are heavy duty so you can run pumps directly from them eg leave your laing d5 on setting 5 and have the fan controller adjust the voltage supplied to the pump up to the max for full control of your pump speed and water flow.

With the fact it can monitor and respond to changes in flow rates, water temp, cpu and gpu temp and fan speeds, you can set the software up to have full automatic control of your entire system.

It really is the dogs danglies as far as fan controllers go.

I reckon it would take some setting up but once done, you would be sorted.

Why isn't this an option? Or is it folding?

If it is, then you're cooling a fully loaded system which will cost more to silence.

As for whoever told you that a rad could only do 50W, they shold stop spouting BS. The specifications of most rads are available fairly freely: e.g. link found in about 5 seconds.
 
Bit strong Mike, I don't know of anyone testing the performance of a computer watercooling radiator without any fans at all.

50W clearly doesn't mean anything without a temperature difference, but 50W through ten degrees or so seems to be the right order of magnitude to me (for a radiator that doesn't have any fans attached).

Edit: Nice one Greebo, the mini ng in particular looks good to me. Thanks for the link :)

Running the rad passively i meant.

Martinm210 from extreme systems posted this.

I tried running the TFC 480 with only a 150 watt load. I ended up having to shut down due to overly hot water temps 50C+ after about half an hour.

You could probably do it, but you'd need something like a quad rad to cool 50 watts or something along those lines. The standard tube/fin type radiators common to today's radiators are just way too dense for passive cooling.

Tbh I forgot about them until your post and always said I would treat myself to one when I did my next build, which I have just finished.:(

I love the fact that you can switch fans off completely and set up whatever profiles you want in the software.

Add the fact it can control your pump voltage and hence your flowrate and the product is a winner in my book.

I can see it now. Gpu getting too hot, pump ramps up and fans on the gpu loop increase to keep it all under control and automatically decreases as temperature drops. Drool.:D

I think I may have to get one bought and get my new rig set up on it.

Didn't catch the passive bit.

Still, don't understand why someone who has such easily disturbed sleep needs to have the computer on at night?

Greebo, have you bought a bigNG now? If so, how do you find it?

I am in the process of assembling the kit for my next build (to be built over the Xmas hols) and I am looking for a pump and fan controller. This one seems to fit the bill, so I'd be interested to hear any feedback. I'd also be interested to hear of other alternatives.

Cheers
John
