Ah, summer... how is everyone's water temp holding up?

Audioboxer · 10 Jul 2022 at 21:00

Admittedly the above screenshot is pulling 600w whilst in FF7R.

Resulting in the hottest my GPU has been all year tonight.

I've got 4 radiators in this build, even that's not saving me from this heat in the UK lol. I know that GPU temp is still great all things considered, but it's a noticeable jump from where I usually sit due to ambient increasing.

Normal load temps for me, like from a week ago, are more around 30~33 degrees on water and GPU around 37~40 degrees.

Winter is always the best time for watercooling lol

With the room at 24 - 25C, from running Division 2 for a few hours, hottest part of the water loop from the CPU was 36C. Loop at idle is 27C, Aqua Computer reported 35.1C as the highest. GPU 46C, Hot Spot 52C, Memory 50C. Highest CPU core was 64C with most of the others 60 - 57C. Fan speeds were 1100 and 1300rpm.

Water temps oh boy i saw nearly 54c after a few hours on Star Citizen last night, the gpu was hitting nearly 58c when usually it would sit around 44/45c. The room was HOT!

Surprisingly memory junction and hotspot were only around 65c peak. CPU never breached 60c, probably the coolest part of the system.

I hope that is at least hard tubing lol.

Yeah it's funny watching my ambient temps, water temps and GPU rise but the CPU stays the same. Just shows in my case my 5950x is limited by the ability to take heat off a 2 CCD chip, not limited by water or ambient temps. That'll be the case for nearly everyone with these modern CPUs and single core temps (seen during gaming).

Yeah thats with PMMA Acrylic tubing, no way soft or PETG would have survived lol. It was bloody toasty! The ambient temps were in the 30's lol, i was cooking in that room.

Looking forward to winter tbh seeing those chilly low 40's again and heating the room up to keep me warm lol.

All my years watercooling
Never actually measured coolant temp
But the other day I bought my first water temp monitor from mm
But it's too hot down here in the sunny South East
For me to be bothered to go fit the thing now lol

What are you guys using to report the temp?
Looks like corsair software in that image?
Should say I got a fitting with a wire on it not a lcd display one

I bought an actual water temp lcd reader that i soldered an Alphacool G1/4 probe onto it that gives me a temp read out. I don't have anything to compare it with though so i don't know how accurate the readout is. But judging from the ambient temp to the coolant temp is around 8-10c delta i don't think it's that far off.

Yeah I've got a Corsair XD5 which comes with a temp sensor you plug-in to the reservoir. The other temps (air) are measures from Corsair commander pro temp probes.

I've also got one of the in-loop flow meters that also measures temp. The resorvoir temp probe tends to read about 1~1.5 degrees higher than the flow meter screen readout.

I run my fan profiles off of my water temp. Makes it easy to have silent operation during no loads.

Mcnumpty2323 · 11 Jul 2022 at 14:57

Thanks guys
Think it's actually the Alphacool one I got
Though am banned by my missus from soldering lmao
After a slight accident where the soldering iron
Rolled off the worktop
and i caught it by reflex to save the carpet getting burned
Of course I caught it by the hot part
I highly recommend never ever doing that lol
So won't be attaching a lcd screen to it

But I actually have a commander pro somewhere
Had forgotten it has temp sensor capabilities
I could use that to double check the motherboard readings I think
As really don't like Gigabyte SIV software
Though don't want to install the commander pro permanently to read the temp
As it just more wires and control boxes to deal with

Aquacomputer - multiple probes in the loop and average the result to get a reasonable indication of temp. Probes on outside of case to get ambient. Aquasuite can then work out the difference.

I did wonder about multiple probes/sensors
Though I thought after the PC has been running
For a while
That the loop would reach equilibrium
So the coolant would be same temperature anywhere
Do you see any noticeable difference between your probes in the coolant ?

That's what im looking to do next on my SFF build, but the aqua computer quadro is out of stock atm so will have to wait until then.

BeeP · 11 Jul 2022 at 16:04

Air con in PC room, what is this summer thing you refer to?

Mind you I have to wear headphones as I cant hear anything over the air con....glad I spent ages making my PC super silent.

You could look at the Aqua Computer OCTO - 4 more fans for ~£18 increase and is in stock now. Can also put the pump (PWM) on it.

Note that the Octo/Quadro require Aquasuite running to perform any calculations.

The coolant should reach an equilibrium, however there is usually a slight difference between the sensors (due to measurement tolerance). So I just take an average to even it out a bit.

Its not usually a large difference, usually within 1C.

Mcnumpty2323 · 11 Jul 2022 at 18:52

Yeah 1c is within margin of error
Nothing to worry over
These sensors connectors don't have polarity do they?
Ie doesn't matter which way around they go on motherboard pins?

ballj · 11 Jul 2022 at 19:25

Nah they do not have any polarity. They are essentially resistors.
Take a look at film Thermistor for more info - think Aquacomputer uses 10k.

drakulton · 11 Jul 2022 at 19:29

The shower was a bit hot first thing this morning, but other than that, fine.

clone · 11 Jul 2022 at 20:52

This is why I have six 140mm noctua 3000rpm fans in my case, summer be gone

I use HWiNFO fro reporting the temps, I have a probe just in front of the intake fans to record the temp of the incoming air and one in the coolant loop just before the reservoir.

I`m not keen on the SIV software either but I set my pump and fan profiles in the bios and just use Fan Expert 5 to check the settings are the same, occasionally it has `forgotten` settings and I`ve had to reset them.
