Silence Is Golden
Target: System water temperatures to go no more than 10 degrees over delta, with fans at a maximum speed of 200rpm.

Backstory:
Firstly a quick backstory in to this build, I built a loop a few years ago in a much smaller NZXT case, finding space lacking I moved up to a core P5 shortly after with a 420GTX Hardware Labs Rad and various other bits, I ran this configuration for a while but eventually wanted better temps and less noise, I needed more rad space. It was hard finding a case that could hold more than 2 480mm rads, when I found the Level 20 XT it ticked all the boxes. In this build I will be using the radiator space available, putting in 4 x 480mm radiators.

This log is an evolution of an existing system rather than a new build, various parts have been ordered, and some still need to be ordered. This cooling system upgrade is also in advance of hardware upgrades that will be occurring in a few months. Spec listed below.

Hardware:
Intel Core i5 7600K @ 5.2GHz
Corsair 16GB DDR4 @ 3200MHz
Nvidia FE GTX1080TI @ 2GHz
Gigabyte Z270-X Ultra Gaming
Samsung EVO 500GB
Seasonic Focus Gold Plus 850W
Thermaltake Level 20 XT

Cooling System:
Heatkiller IV CPU Block
Heatkiller IV GPU Block
Heatkiller Tube 200 Reservoir
Aquacomputer D5 Pump
XSPC TX480 x 3 Radiator
XSPC TX360 x 1 Radiator
XSPC TX120 x 1 Radiator
Barrow 16/10mm Compression Fittings
Barrow 90 degree Rotary Fittings
EK Rotary Y Splitter
Mayhems 16mm/10mm Flexible Tubing
Mayhems X1 Red Coolant
Aquacomputer Quadro Fan Controller
Aquacomputer Ambient sensor
Aquacomputer inline water temperature sensor
XSPC inline water temperature display
Artic P12 PWM 120MM x 16 Fans


The cooling system feels quite hefty looking at the list above, a few people have mentioned to me that it is "overkill" but it doesn't feel it. The radiators are the XSPC TX range, these are ultra thin at circa 21mm with a FPI of 22. These will be paired with Artic P12 fans in push configuration on all radiators. The P12's will be hooked up to a Aqua Computer Quaddro fan controller which will look at the water temperature relative to ambient to calculate the delta. I am going to split the fans in too 4 channels and set them against a custom curve, with 2 channels of fans switching on at 200rpm when water temperature is 5 degrees over delta, and all 4 channels on at 200rpm when the water temp is 7.5 degrees over delta. When water temperature is less than 5 degrees over delta the fans will run at 0 rpm. At that point the only noise from my system should be from the pump, which will also be set against a curve. The pump/reservoir will also be sat on a heatkiller reservoir mount to decouple it from the case floor and on to rubber mounts.

Anyhow enough words, here are some pictures of the build currently:

Look at all that space! This case could easily fit in another 240mm rad in the back, hopefully that will not be needed though.

Wow that case swallowed the rads up!
Surely you have the space for thicker low FPI rads? What's the logic with going for slimline?
Are you having a rad or two between the CPU and GPU? Where's the water temp going to be measured?

A thicker front rad would not have fit, and if the top rads were thicker the 120mm rad would not have fit. That would be 480mm worth of radiator gone.
Additionally the XSPC TX rads are incredibly well suited to low RPM applications, they give me more space to work with and the price is great too.

In terms of runs, I am not sure what will be placed where as of yet, I need to have a play really and see what works. Before that I am waiting on some 90 degree fittings to squeeze on to the front rads bottom ports.

Not sure where the water temperature sensor will be placed as of yet. I don't think it will make a difference where it is placed as the fluid should reach an equilibrium temperature through out the entire loop provided flow is sufficient which it should be.
 
I wasn't questioning you to suggest you should've done it another way btw, purely curious as my understanding was the thinner rads may have left some thing on the table. You've certainly used the space effectively and I'm sure it'll be brilliant for years to come!
It won't really matter where the temp sensor goes, as you can tune to suit, I moved mine around a bit a while ago just to see where it was hottest but I have a 480mm x 60mm rad between each component so plenty of headroom too.
Works much better to have a rad between the CPU and GPU if you can.

Hi mate, I didn't take it that way haha, appreciate the input. Sweet! I will be posting here during setup and when running tubing. Hopefully I can find an aesthetic yet optimal setup.

One thing I am not sure about is the drain valve placement, I feel like the radiator lying flat on the floor might be the best place.
 
So almost all the parts have been ordered at this point apart from the hose clamps. I switched out the 11mm/16mm XSPC Tubing for 13mm/19mm Mayhems Tubing (plasticizer free) which was recommended to me by numerous people. I am hoping it is still a snug fit over a 1/2" barb even without a clamp. Will test fit and see how it feels when it arrives.

Any how the Aqua Computer D5 and Watercool Heatkiller Reservoir arrived today. Pics below :)


Lovely packaging

Why is 1 cable sleeved, and the other isn't? lol!

Got to love the outstanding heatkiller quality, second to none! Anyhow that is the D5 Reservoir sorted, now on to prepping the next bits of the loop.
 
interesting, Mine is PST version, but lowest is 600RPM...maybe it is because it is driven by the motherboard
Not sure why this could be the case, hopefully they do run at 200rpm with the fan controller! Reviews I have watched state that they have an audible hum between 300 - 500rpm, and around 1000rpm. So 200rpm hopefully is the sweet spot!

at 600rpm they are whisper quiet. it is noticable in a completely silent room but keybaord strike noise is louder than the noise from the fans. @1000rpm i can hear the motor hum @1100rpm no motor hum but air flow becomes audible in a quiet room @1200-1250 rpm air flow becomes audiable in a normal room condition with some ambient noise. it doesnt seem to get much noiser than that at full speed.

600rpm seems to serve me well atm. but i am just curous about 200rpm. might play around with their speed to see what i can get
 
Various parts arrived today. Currently just waiting on a few odd bits to come in from Germany. Did some prep tonight, cleaned the new radiators with warmish tap water to remove any flux, then flushed out the all the radiators, and blocks with 5 litres of distilled water.

Also tore down the CPU block and gave it a thorough clean.

Mine (PST version) run at 200rpm ok on pwm from my 450tomahawkmax.

600 is barely noticeable but at 200 there is no noise (that I can hear)
 
How is the airflow at 200rpm? Are they actually worth having on at that rpm

It's still reasonable as a case fan.
I'm not using them as rad fans, but it should work well with that much rad space.

Even a small amount of airflow through all the those rads should be effective.

The lowest I have set mine to run is about 600 as I don't really notice them at that rpm. Once I have had the PC at load I need 600+to control case temperatures anyway.
 
Had some time this evening to make some further progress.

Need to have a look at where to put this in the case

That seems like a lot of intake and not much outlet.
Hi mate,

I previously had all my top fans as exhaust, when only running a 480 and 360 as intakes, but the case was still getting hot (10 degrees over ambient in the case). Airflow is a major issue in this case due to all the glass panels essentially blocking airflow.

Given that I am using more radiators now, I do not want to be providing them with already hot air as this will drastically reduce the effectiveness of them, I would rather them use ambient air from outside the case, rather than the in case air which has already been heated up by the other radiators.

Additionally judging by the placement of dust filters, it seems like thermaltake intended the bottom, and top radiators to be intakes. I may well have to change this configuration if temperatures do not look great, or even modify the case to get more air circulation.
 
They (case manufacturers) always have dust filters at the top. Not entirely sure why that’s needed as usually it is always exhaust.

are you going to run the back fans a bit faster to get the hot air out?
