A240g something is wrong

[Adab5]

I put together a240g kit with 

cpu  8700k on 1.31v in 4.9ghz

and gpu  1080 i on 2000 

 

when I stress test the cpu on Aida, my max temp (delid cpu) is - 63 

 

when end I stress gpu on unigane heaven- the temps are max 50

 

*but* when I test them both at once

when the gpu get to 48-50 

the cpu goes up to 80c!!!!

 

when the gpu idle the cpu stayes at max 63 and when the gpu is 80-100% the cpu is going crazy, 

 

I took some photos , did I assemble the kit good? I relay afraid I didn’t something wronggg it took me 10 hours to assemble.

maybe its because it is working on two different benchmarks concurrently?

you are not supposed to run them at the same time

Yeah but when I play game that taking 100% gpu and 50-55c

And 40-50%cpu,

the cpu going crazy in 60-65c on 50% use

 

the inside of the case is also *very hot* and the intake front radiator fans, taking in the case *very hot air* insted of cold

Coffe lake is not the coolest platform ever, so You might have to address your watercooling

8 series CPUs are not the coolest in the world (in terms of temperature) So go get some higher end cooling or live with it. 65 degrees is not that bad! Im running at 93 right now!

it means the rad is working, if the air were cool it'd be a problem

you're running a shared loop so that means the coolant has to go through the graphics card first, its temperature raises as it flows through the block and reaches the CPU block in that state, warm, that's why the CPU temp is high

as far as I can see you're using a single 240mm rad, kinda small for a 8700k + a graphics card

Is it ok that I did it as a shared loop, or I could do this better? (I have only 240 radiator) 

 

If if I add more 120mm radiator to cool the cpu liquid, will it help?

The why I setup all the tubes and rad is ok?

between the card and cpu? it might drop a few degrees but make sure it's thick and running in a push-pull config

the PSU is upside down you can tell by the amount of dust in the fan

[orbitalbuzzsaw]

@Adab5 I don't think anything's wrong. The 8700K is a toaster and the 1080 doesn't exactly run cool. On a single 240 rad that's about what I'd expect from that combo. I'd recommend adding another 240 rad to your system BUT be careful you're buying an ALUMINUM radiator - most rads are made of copper and you shouldn't mix metals in a loop

[IAnthonyFX]

you are fine, as explained before it is because it is shared loop, adding more rads will help but I would still keep it a shared loop for maximum peformance.

I also have the same a240g kit however i immediately added the 360mm expansion pack to be slightly overkill for my 8600k and 1080. 

 

At 4.9ghz on the cpu and 120% power limit on the gpu letting it boost as high as it'll go (like 2080mhz) i run about 60c on the cpu (non delidded) and the gpu max temp after hours of gaming of 50c. 

 

You are just riding the limit for 1 240mm radiator. You could try jacking up the fan speeds to try to compensate but theres only so much that little rad can do. 

 

EKWB has the fluid gaming expansion kits specifically for the aluminum loops which i highly recommend you pick up.

Thanks, I ordered extra 240mm rad

 

i will install him up, with exhaust fans, 

but how should I connect him to my existing  loop for maximum gain ?

Loop order isn't 100% critical, but i would splice it in between the gpu and cpu so the new rad dissipates the gpu heat before reaching the cpu

But this is worth the extra 100$ with shipment? , I’m loking for atleast less 10-15c in each of the component if I’m doing 240mm rad to each of them instead of boath together

Loop order is basically irrelevant.

 

Your components heat up the water as a whole and the heat is being dissipated trough the radiator. Yes, if you stress the GPU without stressing the CPU, the latter one will heat up – but not because there's hotter fluid coming from the GPU block in front of it but because the loop as a whole heats up. It will heat up regardless on where it is in the loop. The loop contains way too little coolant (~1-1.5l ish for common loops) for any significant local differences in coolant temperatures along the loop to occur. 

 

Once the radiators can entirely dissipate any heat induced into the loop adding more radiators will only result in less flow.

 

The only thing to bear in mind concerning loop order is putting the reservoir in front of the pump and at a higher level to not let it run dry and to prevent damages.

@Adab5:

Adding another radiator is a good idea but one 120 radiator won't do much. Did you delid your CPU yourself? Have you done everything correctly? Have you checked if your CPU block is mounted correctly? Did you check the PWM pattern for your pump in BIOS? A 240 radiator is enough to handle your system but higher temperatures are to be expected. An overclocked 8700k produces quite some heat and the GPU isn't helping in this cause either. EKWB's loop configurator estimates around 505W of heat for an overclocked 8700K and a 1080TI. One of their regular SE class 240 radiators is rated for ~257W. That means your loop will heat up and while it heats up the difference between loop temperature and room temperature gets bigger raising efficiency. Still: your loop will always run a bit hotter and you will need to crank up fan speeds.

Last question: what case do you use? If your case has poor airflow than it makes sense that your temperatures will be higher. Your loop needs airflow in order to work properly. Your fans need to pull or push the air from/to somewhere and the heated air needs to go somewhere.

Thank you , 

 

 

my case was Corsair spec-04 and  changed to fractal define s today,

 

my cpu is delieded correctly, and he is 15-20c less then before delid as expected (checkd on h100i before and after delid,on stock mode)

 

This is my situation as for today with the new case (almost same as old one)

 

my parts are overclock 

the gpu 1080 Ti is 100+555 so 2020 on 6100

the cpu is 1.335- and 4.9 ghz 

The pump is connect to pump header and in 2500 speed

I have 3 intake fan and 3 exhaust fans 

 

Gpu max 100% test after 5 hours- 65c

 

cpu - 78c after 5 hours of aida64

 

This is to hot for me, 

 

in Simple question, if the airflow will be good and optimal, can I expect , getting both cpu and gpu down in 15-25c each , by adding *more 240 rad* between them or in any other place? 

 so 480 total of rads insted of 240

Those temps are ok for synthetic stress tests considering you only have a thin 240mm radiator. Not great but ok. Your CPU was never cool in the first place and with 1.335V and 4.9GHz on all cores you're seriously pushing its limits. Under real loads you'll rarely to never see these kind of loads. Anything below 85°C for the CPU is ok. You still have enough headroom before it will thermal throttle.

Assuming you have applied and mounted everything correctly, flushed every part of the loop thoroughly before setting everything up, the PWM curve for your fans is adequate and you have placed those fans in good spots (top is probably the best position for your main radiator with the least restrictions imho) you can only add radiator surfaces. 240mm would be good, a 360mm better but I'm pretty sure the step between 240mm and 360mm won't do that much of a difference in the end. It's hard to tell by how much your temps will reduce.

 

For a system like yours I'd go with at least a 280mm high performance radiator like Hardwarelabs Nemesis GTS but since you chose the EK Fluidgaming line you're stuck with whatever EK offers as an Aluminium product.

So.. I added another 240 rad now it’s 2-240 rads

 

temps

 

gpu went from 65C to a woping 47c under 5 hours of 100% loaf and oc to 2030/6100

 

cpu- still 1.34 still 4.8 and  74c in prime 95 small ftt test, 

the cpu was 78 so it’s only 5c Lower, why am I not seeing any change on cpu ????? 

 

I added a pic of how I did the loop, 

 

[airdeano]

what are the temps at total stock? no overclock, no MCE auto voltage?

You are aware, that Prime95 puts your system under torturous loads with AVX? Voltages will go up under those loads. A lot of BIOS give you the option for setting an offset for AVX loads. Some Prime95 versions are worse than others in regards to AVX loads. 73°C under Prime95 isn't bad though. On air that CPU would probably boil at over 90°C. Anything under 85 is considered as absolutely safe. The limit is at 105°C. Your CPU will throttle down at that point.

 

It is a bit würde though that temps didn't go down a little bit further. Did you try reseating the waterblock? Are you sure you used enough thermal compound when delivering? Are you sure you applied your OC correctly? Have you tried stock clocks and voltages? Have you tried a different stress test?

I tried re paste thermal and nothing changed, 

 

I tried Aida 64 and the max is 67 (before the new rad it was 74) which is totally different, picture but still way less then I wanted the temps to go down  any other idea?

 

can  a pc in a daily use of hardcore gaming and a lot of video editing can stress more then Aida 64 ? Or I can concern those temps for the real max

 

 

and more thing

5.2hz on 1.39 in Aida 64 max of 77c

is it safe for 24/7 use?

Gaming will never put your CPU under those kind of loads. Especially not those AVX loads. You can try for yourself. Run HWInfo, start a game and reset the system stats. Play a demanding game. Would be surprised if your CPU would even get into 60s.
