Does quick connect limit my temps?

[TheNaitsyrk]

Hello there.

 

I have 5x 480mm XE rads in one loop for a CPU, one pump on each end of the loop, so two pumps. They all cool only one component the CPU. Water in and water out for the CPU has quick connect on each side. 

 

Will it impede water flow so much that my temps and radiator space won't matter?

 

I don't have a flow meter, and I'm contemplating buying one

depends on the quick connect to be honest.

i used some of those alphacool HF quick connects and flow was awful. i swapped them our for koolance QD3's and everything has been fine ever since.

To be honest, i think the main thing limiting you isnt flow rate but ambient temperature, theyre such big rads that the water is probably close to room temp by the second rad, maybe running the cpu on cinebench for an hour it might not be cool until the 3rd rad but i dont think at the VERY least that the last rad is doing much of anything bar impeding flow tbh, i could be wrong, but i think the issue isnt flow rate imo

 

But not gonna lie, dont know enough about water cooling to tell you about the quick connects or if having that many rads will actually help or not

Not in a way that will matter in the slightlest.

 

Basically your loop is so beyond overkill for even a 14900ks it wont matter at all.

 

Dont drop convenience for like 0.001 degree difference if there is even because well you gotta have a pretty darn powerfull pump to be flow limited and desktop watercooling pumps aint that. Unless you have a garbage special quick connect.

 

If you want colder temps you need colder water and probably if you disconnect 4 rads the temps on your cpu will simplt be the same. Its because so much heat exchange can happen that by the time the water leaves the rad its most likely at or near room temp again.

 

Since you can't really make heat exchange between the cpu nd waterblock better (the real bottleneck really) because thermodynamics n stuff the only way to go colder is go colder than ambient which I DO NOT RECOMMEND because condensation kills all electrical stuff.

That's my loop, quick connects are QD3s

That's my loop 

Wait are these in series? As in one after the other with no fresh air in?

 

That has basically the same cooling performance as 1 rad since there is no cold air comnming into the system eventually the air inside of thisbsystem will equalize to whatever is the coldest air that came out of the first rad

 

Sorry just saw they were flipped my bad

 

Anyways this is so much overkill nothing matters here. You can have crap flow it will still be darn fine.

 

You'd ebtter have a beefy af pump or even 2 inseries here tho

One D5 pump at the beginning and one at the end of the loop

The problem that I'm having is at LLC7 1.4V which is about exactly 1.359V under load (as per CPU-Z) and Core Temp shows exactly 420W of load. My temps start at around 78-80c hottest core 83c and then it ramps up to about 87C (85c average) under extended CB23 load 6.0 and 4.8Ghz. 

 

Some people I know have LLC8 1.390V which is probably like 1.41V in CPU-Z gets the same temps.

 

My ambient is 20c same as his. Trying to understand what I'm doing wrong here. Should I buy a flow meter?

Colder water = lowering ambient temp or stright up hooking to a chiller

Chillers are kinda meh cause too warm and condensation risk then you look at phase

Single stage too warm to keep completely under 0 (aka becomes pointless)

 

Next thing you know you are building a cascade system or dissassembling and modding a cryocooler and you are looking at days if not weeks worth of physical work, research, etc. a very power hungry cooler, -100c and under load temps, hundreds if not thousands of $ burnt, but 7ghz+ all pcores at 1.6v+

 

 

If you dont go straight up -100c cryocooler only other options are to keep binning more cpus or set your ac colder for lower ambient temps

 

Honestly id just settle if i didnt want to go out and build a cryocooler just for the cpu, 6ghz pcores and 4.8ghz ecores is already pretty decent

 

Yes i know diehards hate settling (ask me how i know and why im imc binning bloomfields + gulftowns) but there really isnt any other way at this point, you are stuck with lowering your ac temp for lower ambient temp, binning more cpus, or building a cryocooler, and only one of those seems to be the most feasable and that is lowering your ac temp

Its actually better to put them directly in series as that is far more efficient to create head pressure. That can be a fun lil "upgrade"

Quite literally you are at the limit of what 20c water can do. There just isnt enough of a temp delta.

 

Also you are under 100c so totally fine.

 

Keep in mind no cpu is equal and that also means no heatplate or solder job is equal. There are a bunch of variables here that can increase temps. I highly doubt its your loop.

 

If you want more water blasting through even harder just put the pumps in direct series (and make sure they run as close to same rpm as possible) and see what that gives.

 

You're on the bleeding edge here. Simply running into never accounted or tested for situations so variance is normal

I'm on direct die. Same way to cool.

No chillers thanks

Yeah you're simply at the limit and luck of the silicon lottery and minmaxing the super ultra tiny gains in the waterloop that wont really matter at all.

 

You've pushed your hardware about as far as possible in the constraints you put and theres little to nothing else to do.

 

It was never built to be in this shape and is thus tested within the manufacturers tolerances. Which can mean that you get these variations when pushing them well past normal circumstances.

I will test today with additional pump, as much as I think you're correct it will put my mind at ease

is there not a website that sells bined cpus? if you dont care about moeny just spend some and get a bined one.

My one is already binned, that website went bust btw
