Cooling Wars: Episode IX - The Rise of Air v Water

[thesmokingman]

lol at 60c+ water temps the tubes are gonna feel like fresh cooked spaghetti noodles.

Spikes?
Sorry for asking the same question 2 times but the first one wasn't answered.

Sorry @ work and didn’t see, no spikes nice and mellow until shit gets real

I like how this thread turned into water cooler people's pretext board.

Hi,
You just said 80c water cooling not 80c water temperature though lol

Oh right sorry I get you now , you knew what I meant though.

Hi,
I do now but didn't before
You're spot on with the dead pump soon temperature though 60c bad

I've not run into 50c water you've run into though
Mine stays at or under 40c maybe it's the mora3 360 kicking in preventing that :/

 

[FireFox]

I am not all Watercooling.

Nice, but self harm, is not a good thing.

Hi,
Another build is born

 

[MxPhenom 216]

Water cooling is imo better for a gpu, mine is in the 20's idle and no higher than 50 load.

It would be the same way if CPU didn't have IHS. GPUs benefit a lot from water cooling because the block is slapped directly to the die.

lol at 60c+ water temps the tubes are gonna feel like fresh cooked spaghetti noodles.

And if you run PETG hard tubing, those tubes will start to unbend themselves and disasters can happen. That won't happen with acrylic tubing.

If your water temps get over 45c there is something wrong.

I only hit 50 with the right combo of load and not wanting to hear my fans.
And I am fine with that, I don't usually run it that way now ,it depends how far away the pc is from my sleeping ears .

Though I do set it up to run warm in winter for semi free, it's running Fah and Wcg anyway room heating, it's quite effective.

And is why I know the max allowed water temp .

Specifically I setup the temps fans etc how I want, and max cooling is just one mode, max room heating being another, with profiles it's easy to mix it up.

My tubing melted overnight​

Water is best when it is overprovisioned. There is no disagreement on that front. However, the main difference we have got is about air when I say, air is best when it is maxed out. They have different highlights imo.

High performance air cooling.. loud AF.. you can run those quiet Noctua fans but that isn’t high performance air cooling lol.. that’s cooling quietly.. mid performance

As much as I dislike winter as I age gracefully, it’s still good for computers with loud fans

Hi,
Seasonal overclockers fun time, air or water cooled because for these few months we all have something in common finally

Next year I will dip my toes in water. Waiting for the wave to take hold here for the 4th time. Many uncertainties right now.. mostly with my wife and kids, the care home she works at is closing and she might be home with the kids if they close the schools again. That means less moneys for my hobbies

That is why i run acrylic hard tube, it takes a lot more heat to effect its structural rigidity.

How much money you spend is not in direct association with what you get out of it. Hobbies can be utilities. PC can be free heating, believe me it just needs a good and efficient cooler and you have a cozy radiator with led lights.

I assume that the 80c your talking about is just temp spikes, right?

Nope, steady-state under all-core loads or heavy single-core loads. A single CCD consuming 120-130W gets hot. Well, with my current config it sits around 75°C, at ~4.55GHz/120W doing things like video transcoding. At stock it ran somewhere between 80 and 85 - though I've also changed my fan/pump profile since then. The reason is pretty simple: the Aquanaut is a reverse-flow water block, i.e. the DDC pump doesn't push water through the microfins, but sucks them out through it. That leads to relatively poor utilization of the cold plate, and thus high temps. My loop is configured for silence first, fans are controlled only by water temperatures and not component temperatures, which when coupled with low pump speeds means the CPU is allowed to run hot. Though I've configured Aquasuite to switch over to a 100% fan speed/60% pump PWM (which is essentially 100% speed - its PWM response is weird) profile if CPU load is above 90% for more than 10 seconds. That's what nets me temperatures in the mid 70s under full load - though IIRC Handbrake uses AVX. Haven't tested any lighter all-core loads after tweaking.

This is what a pretty typical desktop usage scenario looks like for me:

Yes, the intake is quite hot, they've just started ramping up the central heating in my building, and it's taking some time getting the radiators dialed in. Typical fall

I think 80°C is definitely biofouling territory. Whoever runs water coolers at that temperature is asking for it.

If your water is 80°C you're definitely not getting biofouling, unless you've sampled some extremophiles from your nearest volcanic sea floor vent. Most bacteria and other organisms die at around 60°C. The problem is that your pump, tubing, fittings, o-rings and other components wouldn't do well under that temperature for long. Plus the thermal transfer between water and a hotter component would be trash with just a 10-20°C delta between them. Also, where did you get 80°C liquid temps from?

That is how you get a dead system long term.

Lolwut? Show me proof of a CPU that died from runnning at 80°C with a TjMax of 95-100 and I'll give you $100. CPU/APU/GPU silicon has no problem with those types of temperatures unless there is something seriously wrong with it. Heck, most laptops idle in that temperature range (as that's their only way of being reasonably silent at idle). And while laptops do fail often, the CPUs are not what typically fails - that's mostly batteries or other components failing due to them not handling high temperatures well, not the CPU.

This was a reply to that. You need to dissociate between cpu life and loop life which is heavily compromised by temperature.

Yet you were the one bringing loop life into this, after I talked about my CPU temperature?

How much money you spend is not in direct association with what you get out of it. Hobbies can be utilities. PC can be free heating, believe me it just needs a good and efficient cooler and you have a cozy radiator with led lights.

Eeeh ... unless you're running some crazy HEDT CPU and a few GPUs that heating is negligible. Most electric heaters are 1000-2000W if they are meant to produce noticeable heat in anything but a very small room. A PC outputting 3-400W does obviously deliver some heat, but it's really not a lot. And calling it free is also a bit of a stretch, given that a $100 high quality space heater can do a lot more for a lot less.

That's an example of what people are afraid of with liquid cooling.

That is why i run acrylic hard tube, it takes a lot more heat to effect its structural rigidity.

Acrylic has other problems. I generally recommend soft tubing.

 

[mtcn77]

Also, where did you get 80°C liquid temps from?

Dow Chemical Company?

 

[Valantar]

Dow Chemical Company?

Uh ... what? Where in this thread. That was the question. Or are you just pulling in entirely unrelated and irrelevant information at this point? Heck, aluminium melts at ~660°C, so don't run your CPU that hot, I guess?

 

[freeagent]

No not the end of the thread.. different strokes for different folks!

I am a pussy by nature so I stuck with air all these years

That’s not to say I’ve been secretly wanting something better this entire time..

Somebody by the name of, 'you,' said you ran your water cooler that hot. Anyway, you don't determine biofouling, Dow Chemical Company does. That is where the biocides are produced.
