hot temperatures with custom loop

[pummetje]

Hey guys i hope everyone is doing fine

I have a little issues with my watercooling setup because it gets a little hot when idling and after some battlefield and other games the idle gets even hotter ( same after 30min idle)

My temperatures for cpu idle is 40c and gpus are 43c idle after gaming this idle is 50c for the cpu and 45c for the gpus.

During gaming my cpu is around 60c and gpu around 55c and my ambient room temperature is around 20c sometimes a little higher but not over 25c.

 

i know the 4790k still has ''ok'' thermal paste between ihs and the die itself but im not planning to delid it sometimes the idle temps are 30c but it will increase and stay 40 or higher 

and i know the r9 290 cards run pretty hot because they have 250watt tdp for a single card but load temps are great and the cpu and gpus normally dont have that high temperature at idle.

 

The things i already tried :

 

- Remounting all the waterblocks and renewing the thermal paste with some new ek ectotherm paste ( did this multiple times )

- Cleaning the loop i have opened all waterblocks and cleaned waterblocks in the inside and cleaned my radiators with vinegar + boiling water 

all blocks and radiators look like new after cleaning.

- New clean advanced lrt tubing 

- New coolant i went from feser one to mayhems x1 

- Removing all airbubbles from the loop ( i did this with shaking the pc and radiators alot and there is no air anymore in the loop )

- Adjusting the fans and all fans on full speed dont make alot of improvements 

- Adjusting the d5 pump to speed 5

-

Checked for kinks in the loop but there are no kinks

- there seems the water is moving at a decent rate i see the water coming in the reservoir ( i see water moving in the reservoir and when i bleeded the loop air bubbles moved pretty fast ) 

 

specs of my pc : 

 

GIGABYTE G.1 Sniper 5 with EKWB fullcover waterblock

Intel core i7 4790K 4.5ghz 1.25v vcore 1.2v ring voltage rest of voltages are on normal with ekwb supremacy clean waterblock 

corsair dominator 16gb 1333mhz 1.6v with ekwb monarch waterblock 

2x sapphire r9 290 with ekwb fullcover waterblocks and ekfc terminal paralell

asus xonar essence stx soundcard

coolermaster silent pro m 850 watt power supply

Swiftech mcp655 pump (its a D5 ) with ekwb X-top v2 pump top

 

the radiators are 1x ekwb 240mm radiator and 1 huge copper car radiator its the length of the 750d from corsair and half hight of the 750d

on the car radiator there are 2x 230mm fans from bitfenix

 

here is a little youtube video so you can see the flow in the radiator and tubing routing etc

i really hope someone can help me with this because it seems really weird the load temperatures are pretty amazing but idle is a big problem 

thanks alot

What kind of rad is that?

double 120mm, 140mm or 200mm?

Can't really see that clearly...

[ind3x]

Which way is your water pumping?

If you're pumping water through GPU's then into CPU then you'll obviously have higher CPU temps.

But what rads are you having?

is that 2 240mm's?

[wardude1]

first of all it is a little high but not that big of a deal.

secondly you have connected everything in one loop which might cause the water run pretty slow which might explain it. and you are pomping the hot water of the dual 290 to the cpu wich is also ineffective if you want a cool cpu.

but is a sweet cooling setup

Loop order doesn't make a tangible difference in performance in terms of PC watercooling since the fluid is moving around so quickly. 

 

@pummetje 

Your idle temps for the CPU is a bit high but your loaded temps don't seem to be too far out. I would double check to make sure the block is properly seated. Also I assume you are using a 200mm or 230mm dual rad?

water is going :

 

pump>230mm rad>ram>cpu>gpus>external car rad>mobo in>mobo out>res and all over again

load temps are great and the blocks are mounted a couple times again followed by the manual

there are 2x bitfenix spectre pro 230mm fans on the car rad and on the 240mm there are 2x noctua nf-f12 fans

[The Benjamins]

1. you have 3 parts being cooled by a 240mm rad, thats pushing it; EDIT maybe the car rad is not that effective
2. intel 4790k get hot when pushed passed 4.5 GHz

the gpus at 55 is fine, they work fine at 90

and sadly the 4790k may have some issues with the TIM so you can cool it as efficiently as the 290s

 

adding a rad will help

 

I think its just the 4790k OC that is causing it. I cant keep my 4770k cool at 4.5 to save my life. I run it at 4.4 and it gets up to 70 on high load. when my R9 290X stays at 50 MAX

Is the environment your in very humid from what you have it should be good cooling with the car rad and 240mm rad. Only other thing I can think of is the car rad isn't very effective at cooling since those usually have very high RPM fans due to it's fin density. Currently those 230mm fans are only at a max of 900RPM.

i have 1x 240mm rad + a car radiator in the loop with 230mm fans so it should be enough right? the car rad is copper and pretty big

I blame the 4790K OC. I hate how my 4770K just can't be cooled

The 4790K has that Intel TIM issue fixed I can push mine to 4.8GHz with no problems with temps or thermal throttling.

it could be a bad OCing part (specifically his)

 

what are you OC setting like voltage and stuff. you could be running a high voltage.

[W-L]

 

-PICS-

 

 

Try cranking the fans to max RPM and check temps that's a double stack fin array, and from the looks of it super dense. Most car rad fans are around 2-4K RPM. 

 

Also just a side note but make sure the rad tanks are copper or brass ends since it will become a mixed metal loop if they aren't, but Mayhem X1 should take care of dissimilar metals also.

I got mine at 4.8Ghz @1.275V, it idles at around 30-35C once the loop warms up.

everything exept the cpu is overclocked and the cpu voltage is 1.25v so its not alot of vcore 

i can insert a aida64 page with all voltages

cranking the fans to the max make alot of noise and doesnt really make that much of a diffrence it still is about 40c idle and gpus 41c

 

the tanks in the radiator is copper so thats not a problem i guess

[f5alcon]

The idle seems high, My idle is 28-32C but load is about the same, and really as long as you are not getting into the 90s it doesn't matter.

it will not reach above 75 with occt avx but i think my idle temps are quite alot 

like about a ago i played battlefield for 30 minutes or so 

cpu 69c and gpu 55c max and after idling for 20minutes the grapicscards are still 46c and cpu 50c

i dont think its normal

I am just saying how some chips out of a lot run better then others.

Ya that not that high, I would check thermal paste, also what pump you have? maybe the car rad is too hard for the pump to push the liquid through fast enough. if you can get you flow rate or see how it is flowing check it ( you may be about to see how its flowing by looking at your res.) do you have the pump slowed down or is it going at max? does the air being blow though the rad feel hot, warm, cool?

 

I do feel like you loop is not pushing out the heat fast enough. your 290 should be at 45-50 IMO. (based on mine running at just under 50 MAX)

[W-L]

yes that is possible that he has a hot running CPU I ahd a buddy who had one that idled at 40-50C and would thermal throttle with the stock cooler during stress tests which was not the best.

Are the fans PWM? I agree that the idle temps are high, just that it doesn't matter, there is not a performance difference, nor does it impact chip life to idle 10C hotter.

i have a swiftech mcp655 with ek xtop d5 running at the max speed

with only cpu stresstest like aida the rads are 30c with battlefield the rads are 40-41c

the fans on my 240 rad are nf-f12 pwm and car radiator fans are 3pin 230mm bitfenix spectre pro

all other case fans are pwm and i can controll all fans with gigabyte fancontrol software and the fans are running at 1000-1100 rpm on 240 rad and 700-800rpm on car rad
