New loop high temps 65C

fenchu · 5 Jul 2015 at 09:36

Hi , i was hoping i could get some advice with referance to my setup i recently moved to water cool and built a loop for my titan-x the loop consists of

EK - XRES 140 D5 vario
Black ice GT Stealth 240 mm Radiator
2x Aerocool DS Edition fans Pull
2x Shark fin push
EK Water Blocks EK-FC Titan X - Acetal+Nickel & backplate

The only component on this loop is my Titan X the radiator is at the bottom of my case and my case is a phatnek enthoo prime see picture :-

I was recommended the components via another thread , my temps after 15 minutes of heaven stabilise at 65c which seems way to hot. The radiator is hot to touch and im not sure if its enough for my setup.

Should i install another 420 or 480 radiator into my loop with exisiting radiator or get rid of the raditor im currently using and rebuild loop with 420 or 480 radiator in top of my case ?

XSPC EX480 120mm Radiator - Black

XSPC EX420 Triple Fan Radiator
https://www.overclockers.co.uk/showproduct.php?prodid=WC-089-XS

these are the radiators i was looking at , at present i dont feel comfortable using my pc as i say under load im hitting 65c which cant be good for the tubing with it being rated at 60c same with the pump.

**edit raised case of floor half a meter removed air filter put it next to open window and still roughly same results 15 minutes of heaven and 63c.

*** solved / Fixed

Maybe try the rad in either push or pull, to eliminate any kind of problem with the mismatch of fans causing an airflow problem.

Also, what exhaust fans have you got in the case? Any in the top? The hot air might not be getting pulled away quick enough.

Can you try raising the case off the floor and see if that makes any difference? It sounds like it's restricted air flow more than anything if your radiator is feeling hot to the touch.

tryed rad in both push and push pull exhaust fans 2x 140mm top of case and 1 in back 2 are intake in front all are Phanteks PH-F140SP. Except the ones on radiator

Done this and ammended first post , rasied case half a meter of ground removed dust cover and only a 2c difference within 15 minutes of heaven i was at 63c.

I'm pretty new to watercooling, does volume of water make a big difference? The res looks quite small and with only the gpu in the loop, perhaps it's something to do with not enough contact time and enough water volume to move the heat away from the gpu block?

65c aint really that bad when some GPU's run in the high 80s on air?

As far as im aware the pump has a temp limit of 60c and the tubes 60c so i would consider it to be bad.

wel ive just ordered some more parts :-

XSPC EX420 Triple Fan Radiator
Phanteks PH-F140SP 140mm Fan - Black / White
XSPC HighFlex Hose 3/8" ID, 5/8" OD, 16/10mm, 2m, Clear
EK Water Blocks EK-ACF Fitting 10/16mm - Black

as i already have 2 phanteks in top of case i only needed to order 1 for the 420 radiator.

as said before its all about the heat has no where to go. either put your rad in the front or top or do as i have done and stand the feet on some chocks of wood

NoNameNoNumber · 5 Jul 2015 at 15:23

That's the core temp not the actual water temp... That will be much below 63°C...
Still not very good though. I have just finished a new WC build in and enthoo primo with 2x 480mm rads and my temps aren't great... Still working through it all methodically to find what's up.

BRIGGBOY81 · 5 Jul 2015 at 15:45

edit just seen he has raised the case. are you sure you have all the air out of the gpu block

FloppyPoppy · 5 Jul 2015 at 16:04

+ is the GPU block correctly seated. What thermal paste did you apply? did you apply the right amount?

EDIT just googled this, cant show the pic as the website has locked copying

We used a Core i7-5960X running at stock speed, a Rampage V Extreme and a custom water-cooling loop consisting of an Alphacool NexXxos ST45 280 radiator and Corsair SP140mm fans set at 7V to cool the Titan X, along with an EK-FC Titan X full-cover waterblock and Laing DDC pump.

So a slightly larger rad but not instanly different

they run unigen valley to test the temperature on it and their titan x on air overclocked hit 62?

and under water it hit 18

cant confirm these numbers are accurate but from my experience watercooling 2 x 780s in a loop with a cpu and motherboar cooling on 2x 480 rads 2, 240s and a 120, their temps are similar to what i had so not entirely sure about it.

well i tryed putting the case on feet approx half a meter high but only saw a temp difference on 2c. To put the res in the front thou i need to remove the drive bays do i not on the primo ? cant move it to top as i just ordered a 420 rad .

I need to get sensor for water temp to get better idea of whats happening there.

Well i have no air bubbles in line or resorvoir so im guessing yes + the block seems to be working right ie heat transfered to radiator.

thin even layer spread using mx4.

Just want to say thanks for the help so far guys im sure we can get to bottom of this

BRIGGBOY81 · 5 Jul 2015 at 16:33

just because you dont have any in your line or resevoir doesnt mean that there isnt any in the block water conducts heat so it will appear that its working. sorry but speaking from experience it is one of two things: 1 the block isnt seated properly :2 air in the block

Well im new to this so appreciate the feedback from more experienced users like yourself. Im 9/10s sure the block is seated correctly but i can redo again just for piece of mind when i fit new rad.

To get air out of the block then is there any effective way , as far as aware im best to tilt case side to side flicking power on / of.

Was thinking about upgrading fans as well on 240 to these :-

Corsair Fan, SP120 PWM High Pressure Fan 4 pin

or these :-

not just sideways i had to do most of mine upside down and every direction possible. also shake it like mad.

Ok ill give that a go once kids gone to bed and report back thanks

What speed is the pump running at

?

im on setting 5 at moment did try 2 but temps were about same 3c differnce roughly.

Flipped case over numerous times and shaken side to side but still no good running heaven same temps will try again later.

quick question , should the fins on the radiator be warm at all .. as there the only things cool.

BRIGGBOY81 · 5 Jul 2015 at 18:25

yes they should be warm and sorry to sound like iam repeating myself but it sounds like you have air trapped. mine took 2 solid days of rotating and shaking and turning the pump on to bleed mine.

there not warm at all even if i stop fans , the front entry ports and rear + sides are hot would this point to air trapped in radiator as the fins are not even slightly warm ?
