Upgrading PC - impact on water loop?

Still with a target of getting my system as quiet as possible, will a single D5 pump cope with a CPU block, a GPU block, 1 x EK CE280, 1 x 280 Nemesis GTS and 2 x 240 Alphacool ST30?

I am thinking if I am going to break the loop down, I may as well only do it once.
I have some 5.25” bay adaptors coming for my 3.5” HDDs so I can free up all the space at the front of the Enthoo Primo for radiators. This will effectively add 480mm of radiator space, and if that is not enough, then I don’t know what would be.
It is probably overkill, but if I can have the fans just ticking over at 800rpm, then it should be pretty quiet.

My only concern is flow rate through the loop on a single pump, with all the restrictions in place.
I have a few days off work next week, so it is the ideal time to fiddle with my system, as I am changing the Z390 Aorus Pro out for a master to support a better OC.

Short answer is yes, it should be fine. You may find you need to push up the speed a little.
 
Thanks for the response.
Having done the sums, it seems like it may be cheaper (and possibly more efficient?) to drop an EK CE420 in the roof.

The Alphacool rads don’t seem to do well in the tests.

I have my D5 pumping through a 360, a 280, 140, Cpu block, motherboard VRM block and Gpu block and something like 11 right angle connectors (I know, that's quite a few but it's cramped in places!), I did find that unless I ran the D5 at around 75-80% it significantly impacted my CPU temperatures. Above that and it was fine though. I just run it at 100% constantly. Temperatures don't really change beyond 75%.
 
Great, thanks for the info.
I have coolant temp at 35 degrees before I overclock the CPU. Due to the radiators I have, at this temp, the top radiator (gts) fans are running at about 900rpm, and the bottom EK CE) at 1300 rpm. I think I may knock the fans on the gts up to 1100, and double check my pump speed.

I am still tempted to pop another rad in the case though. Probably just one.
The EK PE 240 looks pretty good in push at low to medium fan speeds.
I will fiddle a bit more before deciding which way to go tomorrow.

Imo the GTS is a much better rad that the PE. That being said, it's very restrictive.
 
Yes, so I am not sure adding a 240GTS is a good idea.
Anyway, folding at home is running on all cores and the GPU tonight. I will see what the temperature gets up to, and then OC the CPU tomorrow to see what happens with the temperature when I run the same test.
 
So after running Folding@Home on CPU and GPU during the night (a useful stress test) I saw a max coolant temperature of 36 degrees.
Yes, the fans were a bit noisy, as the EK Vardar Evo ERs were spinning at about 1300 rpm, but I don't think I will normally load the cores and the GPU like that in normal use.

My conclusion is that I probably don't need a new rad in my circuit, unless I want to decrease the fan noise, a bit.
 
Having just found a source for Magicool G2 slim radiators, I am tempted to add two 240mm radiators to my loop.
This can be done for roughly the same price as one 240mm Nemesis GTS. I know the GTS is a better radiator, but two Magicool will make a bigger impact overall?
The question is, are they any good?
These will be fitted at the front and side of my Enthoo Primo leaving the 280CE in the base, and the 280GTS in the roof.
 
So thoughts are still torn between a 420mm top rad, something like a EKWB CE 420, or adding a Magicool G2 slim 240mm (or HWL 240GTS). The CE will cost about €30 more, but will be offset by the sale of the 280GTS.
 
Yes, it is a shame they stopped doing it.
Current thoughts are a 240mm Magicool on the side of the Primo, exhausting out from the case, and to swap the 280 in the roof for a 420 later. I may try and avoid the restrictive 420 GTS, and fit something like a 30mm rad, or XT45 or CE420. I would like to go bigger (Nemesis GTX?), but I am not sure I have clearance with the Mobo.
 
Finally made a decision. I have bought an XT45 420 V2 to go in the top of the case.
Yes, it means the 280GTS becomes redundant, unless I find a way of squeezing it into the side of an Enthoo Primo.

If the additional space gives me enough cooling to run the fans slower, then it will be great. I am probably only going to have fans in pull, tucked in the top of the case, so it should look clean.

It was either an XT45 or 420GTS, but I don’t like the idea of restrictive radiators.
 
I have ordered another Noctua NF-A14 PWM to run a set of three on the XT45 radiator. I think these should be enough, and keep noise levels down to a sensible level.
