Water temps

Robzere31 · 1 Aug 2017 at 20:03

Those of you with custom WC loops, what are your water temps.

Just wanting to compare my own to other setups, mine seems to max out after a good session around 38-39c
Gpu is around 45c & cpu 60c

This sound about the norm for a custom loop?

VKleita · 1 Aug 2017 at 21:13

What is normal ?

I remember reading somewhere that soft tubing can start to cloud going above 35c, that might be complete horse poop thou.
Ever since then Ive been paranoid about water temp.

it rolls between ambient and id say roughly 29c while gaming, if it goes above 32 one of my extra 200 MM fans kicks in and tends to sort everything out.

Robzere31 · 1 Aug 2017 at 22:24

Mmmm interesting, I have my fans running fairly low so might have a play around with fan speeds to see if they make any difference.

RSR · 1 Aug 2017 at 22:49

I've read around 40c should be the topend for hardline tubing but id get a bit nervous if it goes over 35c.

What case are you using and is it getting enough airflow through it?

Mine runs around ambient temperature or +2/3c more some times but all my fan curves are set to use the water temp as its data source. It's also silent as well unless I have the fans on a more aggressive profile.

Robzere31 · 2 Aug 2017 at 11:52

thinking on, front radiator fan placement, would you say intake which would mean hot air from the radiator going into the case, or exhaust?

Case is a Phanteks Enthoo Pro M BTW.

Me (And no I'm no expert)

I hate the idea of a rad Intake, your basically pumping waste heat over components that need cooling themselves.

Air movement can stall around VRM's etc and it always worries me that I could be adding temp to a hot spot already.

If thats actually true mathematically I dunno, but I don't like to take the chance.

Thats what I'm thinking.

Only problem I have is the front radiator would have to have its fans as pull only as theres not enough room to put the fans on the back of the rad blowing through.
I'm going to give it a try tonight & see how temps are affected. I'll also turn the rear fan which is currently an exhaust around so at least there is some fresh air coming into the case!

VKleita · 2 Aug 2017 at 16:36

Certainly worth a try

Only other solution is a case where you can fit them as exhaust rads :s

Due to my madcap setup, my water temps max out around 24-25 degrees in the summer with the fans set at 900rpm. Currently it's at 18.5 degrees C although I haven't done any gaming this evening yet. The highest my water temps have ever been was 27.8 degrees but that was back in that heatwave with the sun shining through the window that the radiator box is set on. Winter water temps are usually in the single figures up to 11-12 degrees after a long gaming session. No I don't get any condensation issues.

Mine sits around 28-30 on low fan level while loaded if it ever hits 32 the fans ramp up a bit to cool stuff down

Chaos666 · 2 Aug 2017 at 23:59

I usually get around 31-33* under full cpu load. That's just with a 240 rad and mu cpu.
When I used to have 2x r9 290 and additional 240 on the front it would reach 38-40

But that was pulling 600w from the wall

Robzere31 · 3 Aug 2017 at 12:47

Mmmm, well that didn't do much to improve things.

Turning the front fans around to make them exhaust & the rear to an intake I maxed out playing FIFA at
Water 43c
GPU 45c
CPU 60c

Just can't see why the water is so warm. Will investigate further tonight.

Chaos666 · 3 Aug 2017 at 21:02

how you measure your water temp?

Fundamentally it means your radiator/fans aren't upto the job.

What have you got?

Though, there's nothing particularly wrong with your CPU/GPU temps.

Xspc sensor on the top of the reservoir.

Radiators are 280mm & 240mm blackice full height.
Fans are 2x 140mm alpenfohn wing boost 2 exhausting out the top,
2x 120mm corsair performance edition on the front rad in pull setup as I can't fit them to the rad in push configuration. (I have a 30mm rad on the way to try out fans in push)
120mm alpenfohn wing boost 2 as an intake on the rear.

Previously tried the fronts as intake & rear as exhaust.

That's seems very high to me, that said I did see simlar temps when I was running my Evlov ATX case.

What fans and rads are you running?

EDIT: Which Black Ice ones are they? GTX's?

Also do you run dust filters on the case? Another thing what thermal paste are/have you used.

Its the same arrangement mine are in which are fine, which would suggest to me it would be air flow over the rads and/or possible a TIM problem.

Have a quick look at your build log, it seems you may have negative pressure in the case which may be not helping. Have you thought about putting some more fans on front rad to make it push pull?

Not enough room for push/pull but I'm planning on swapping to a 30mm rad in the front so I'll have room for push setup.

Just tried running all the fans at 100% & running a couple of benchmarks programs to stress the system.
Water currently at 29.8c after a 30 minute run.

Looks like it could be the fans? I thought the corsair performance fans were ok.
May look at those Corsair ML fans, are they as good as people say for radiators?

I run the ML120's in my build and they are very good another good recommendation are EK Vardars.

Are you running any drives below that front rad? If not you can take the little plate out and flip the rad which should give you enough for push pull on the front.

VKleita · 4 Aug 2017 at 09:52

Corsair performance , so the SP fans? they are designed for rads, the ML are a half and half so I doubt you will see a performance benefit.

If your using Corsair AF fans, then that might be your problem
