Full loop advice

[Nickolp1974]

Currently in my loop i have 2x 360x45mm rads, ek flt 80 with D5 pump, cpu waterblock and ram water block. I want to add vga waterblock to my 7900xtx nitro as it just chucks out way too much heat, if adding it to the same heat what sort of water temp increase can i expect?? this is important because of the ddr5 OC. Would i be better off adding a seperate set up just for the GPU?? or i could squeeze in another 360x30mm rad and would another pump help??? I dont run stock anything so max cooling is essential. Also thought about going external with an alphacool 1260xt45 but would prefer to keep costs down as much as poss. thoughts??

That's not a bad shout with the qdc's but I have to drain loop to install the VGA which is a pita it may just be easier in the long run to get it done

 

[Nickolp1974]

Should be fine with 2 x 360s. The D5 is more than capable of dealing with that loop alone.

Whats your current Water DeltaT over ambient?

iirc about 6-7c

 

[Nickolp1974]

If your gpu chucks out too much heat
Adding it to a loop doesn't
Alter that
The heat still gets chucked out
By the radiators

Or did you mean gpu temperature
Is too high?

A 5950x and an 3080ti with 1 x 360mm x 44mm rad
And 1 x 360mm x 58mm radiator (push/pull)
My coolant temperature now is 28-30c
In summer 38-40c (gaming temperature)

The alphacool would be a good choice
If you're able to position it
Somewhere it's not dumping heat into the pc room
Unless your pc is in a room large enough
That amount of heat/watts especially in summer
Doesn't majorly increase room ambient

gpu temp is ok i think for an 7900xtx but in an enclosed case everything gets hot because of it, under water the fans will push air out the case through the rads so within the case should be cooler even though the ambient temp will rise, just not so direct on the rest of the PC

 

[Nickolp1974]

Cheapest option
Just make sure theres plenty of
Airflow through the case

Next Cheapest option would be adding a gpu block

Next gpu block and another radiator

Next gpu block another radiator and a second pump
1 x d5 would be sufficient though
Only need 2 if separate loop for cpu and gpu
Or for redundancy if one pump fails

Most expensive option
Alphacool 1260 x 45 or x 60
Last I looked you could do the Alphacool 1260mm x 45mm
Plus a second pump and the other bits for
Under £300
Though that would be because could use fans
I already have
Not cheap but custom watercooling isn't nowadays
But the Alphacool is still way way cheaper than a mo-ra4

Though again would be ideal if could place it
Somewhere that gets the heat out the room
Down here in the sunny south east coast in summer
That's my biggest issue
Pc room temperature gets extremely hot

another option i just thought of, as i have to strip down to install gpu block i could add some bulkhead(if you can still get them) QDC's and loop temporarily and if i want to add an external i can, would be mainly for benching purposes, rest of the time run system without for daily

 

[Nickolp1974]

Yeah can still get bulkhead qdc
Can even get a pcie slot cover that you can
Use for them rather than drill holes
Or just putting them
Through an empty space
Qdc are pretty expensive per pair nowadays
Unless you can get some in MM
Or get the plastic versions
Which an ocuk competitor has loads of
Don't think ocuk have those

any idea on how the barrow ones are?? look like you can get a pair for same price as a single koolance

Adding a GPU to your loop will increase the idle temperature of your CPU and everything else. Under load, as long you have enough rad area and cooling to keep the rads cool should be fine, but when I used 3 thick 360s, but had a 3090 (with active backplate), my CPU never stayed as cool as I managed using a AIO. Still cool enough, but the extra heat in the loop pushed the CPU temperature higher.

this is what i thought and the memory is the most important factor as they are sensitive to heat and may lose stability. So ideal scenario is put gpu in its own loop??

 

[Nickolp1974]

Or put the ram on its own
Little loop?
Should be cheaper than a gpu block
And remove heat from the cpu
From the ram equation

Somewhere i have an Alphacool ddc with Little res
Runs off a fan header would work fine
For cooling some ram

rams ok with cpu, never had a problem with that. Already have GPU block on its way, so need to accommodate it. For Gaming other the ram, everything just runs stock but i enjoy a bit of benchmarking thats where better cooling comes into play, raised power limits on the xtx need water to be safe. Currently have a Lian li 011d dynamic, if all i did was game i would do like you said earlier and im sure it would be fine as is with the extra block. Now im thinking bigger case, seperate loop for gpu. So would need a pump/res with a small footprint, still need decent flow to get heat away quicker

 

[Nickolp1974]

heres an image if it works, running a combined OCCT, cpu+ram+light vga usage, for a little 9600x it was pulling 150w! T_sensor is water temp, closed case with fans at around 65%

 

[Nickolp1974]

as stated i like a bit of benching, but most are component dependent, rarely is vga and cpu used at full whack together and if they are its generally a lighter load on the cpu. So with that in mind i may scrap dual loop idea, that would save me£150, been looking at the XL evo version of my case, more room, flexibility and bit better airflow especially if i got the front grill also.
will 1x D5 cope though with 3 rads and 3 waterblocks??

 

[Nickolp1974]

yeah nothing complex regards ram block, 9600x is just a practice chip till either 9850x3d or 9950x3d2, I may just get the 8core if I end up with new case and bits. At stock or just above for gaming 3x 360 x 45 rads will be plenty/overkill but for the other hobby we'll see how that goes. 1st time i tried raising power limits on gpu just for a quick bench, 560w on timespy! https://www.3dmark.com/spy/60876538 not bad on air, wont push any more till its under water!!
this is screen after 2 hours of TM5 stability testing, water 33c max dimms 34c
