Hailea Ultra Titan HC 250 WaterChiller

[FireFox]

Glad to see your enjoying it

It's very quiet and efficient, temps set at 18c, rarely it reach 19c and it turns on for 1 minute.

 

[FireFox]

see if u can get that dew point, lower than me lol!

No windows open

 

[Nicholas Peyton]

enough poncing around at 18c, and push her a lil further lol

looking good ;-)

Great reading for a new chiller user -
Thanks for the info
Hoping for a little advice
I have bypassed the temp controller on my Hailea HC-1000 using the wire bridge method in post #20 so the chiller is in an always on state
and am using a 240V thermostat relay to control the on/off cycles from the mains power.
This is working perfectly

I am correct in assuming that the P1 code on the chiller when below -1.5° is the internal temp sensor bugging out at the cold ??

The controller has an LED display which shows current temp and the temp to sswitch off when running and reaches set temperature.

what temp is the coldest you guys have achieved ?
what temp is the HC-1000 safely capable of going down to ?
I'm currently @ -3°C

what is recommended delay time between shut down/start up ?
is 1 minute too short a time or should I stick with the 3mins that the chiller controller used ?

Currently no load - just 2 loops circulating.
Will takes some pics later and post up along with some shots when a system under it for benching session.

I have the HC-500a.

And yes the P1 code is just the sensor bugging out. Nothing to worry about. (It has lower and upper thresholds) if you go lower or higher than it will display "P1".

My Hailea is only half the power yours is. And the lowest I was ever able to get my coolant temp to was -14c. That was by only running the pump. Then bringing the PC straight back into windows from sleep mode. (the heat generated by a boot-up would of taken me back up to about -8c before I could even start a benchmark.

However bringing the PC back from sleep (or using software from your motherboard manufacturer to down-clock and under-volt your CPU) to get temp down. Then leap out of that condition and straight into your bench! (maybe a quick 3dmark run)?

The problem with Chillers today is they now use a refrigerant (gas) that is more economically friendly. (R134A). But unfortunately it also has a higher boiling point. The closer to that boiling point you get the more efficiency you lose. It's not possible to go below it. I think the boiling point of R134A is -26c.

You're chiller is more powerful than mine. So I guess you might make it to about -19/-20c.

For me to get to -14 not only did I have to do the above, but I had to place the Chiller by an open Window in Winter (-10c outside) so the chillers fan would be drawing cold air through it's self and into the room.

Under normal idling conditions with the chiller indoors -- I don't believe I was able to get lower than about -8c (then by the time your bench finished dumping a load back into the Chiller I'd be at between -1c and +2c coolant temp.

I had a lot of fun with mine ;-)

Interested to see how low you get yours.

Good luck; and let us know how you get on

Really Appreciate the response and so quickly too

Just finished reading another forum post about refrigerant being the limiting factor, so glad to hear that you are able to conform this
and it appears no other "hardware" issues will cause limitations.

I'm in Perth WA which is a Mediterranean climate, BUT it is almost Winter here.
Tonight's forecast looks to be the best conditions for the next few days - https://weather.com/weather/hourbyhour/l/ASWA0604:1:AS

I doubt I will get to your temps even with the bigger chiller because of my ambient temps.

One more quick question.....Did you insulate the tank and compressor of the chiller ??

Now that confirmed no hardware limits on the chiller I feel safer to dial down the temps - I had it down to -5° earlier but wanted to gather more info before going lower.

Cheers

Yeah, there's a post somewhere with all my pictures of how I insulated the tank (pipes leading into it) and tubing. And even my blocks.

No need to insulate the compressor.

Here's one of my posts you might like:

And you-tube video showing ice/frost build-up on my fully insulated 1080 GPU on Chiller:

My CPU is also under Dry Ice. (so just skip past that part)

Hope you have fun lol

Can you pretty please add me to your list of people allowed to view your profile so that I can search your posts for the thread with pics of insulation

this was last night when still above zero, 3°C I think.
I only did the wiring mod and added the external controller this morning.

Frost at 3°C

 

[fast fate]

Frost at 3°C

ambient was probs 15°C which means humidity was high 50's.
Kinda makes sense according to dew point calculator - http://www.dpcalc.org/

Weird, because if i am not mistaken with a 11c/12c room temp and the chiller set at 1c i never saw any kind of frost.

1st time running the chiller yesterday, so I didn't really know what to expect.
If didn't surprise me it was frosting up after checking the dew point calculator, but now maybe I am "slightly concerned".

circulating chiller loop only atm, ambient temp 21°C
coolant temp down to -7° very slow to drop temp now, so might be at limit for daytime use.
Hoping for better/lower temps during the night,
BUT even if not, I got a nice 10° drop in coolant temp from the thermostat bypass mod

coolant temp down to -7° very slow to drop temp now

Minus temp take longer.

Try now.

Hi Knox how's it going?

Long time no see.

I upgraded since we last spoke.

But my 7700k needs more than 1.35v for 5Ghz. So I'm stuck at 4.9.

Thinking about a de-lid.

Not used the Chiller for a while.

 

[fast fate]

Had a session with the modded chiller yesterday on a QX9650 chip.
Coolant temp delivered to the chip was never greater than -1.0°C.
For the most part coolant temp was between -2° and -3°.
I was somewhat surprised and very impressed that the chiller was able to regulate temp so well.
I suspected that the heat from CPU loop mixing with coolant from chiller loop in 10Lt. reservoir would results in high coolant temp.
BUT was excited to see that it was able to keep sub-zero for the whole session.

We played with CPU voltage at or above 1.75 Volt and (I think) the CPU temp didn't get above 35° which I think was pretty awesome.

Was amazing to see in real life (not just photos or screenshots) the temps, being as low as we had using the chiller.
I mean CPU temp (idle) of 5°C when ambient temp is ~20°C - that's just made me happy.

We were hoping to break for 5Ghz on the Socket 775 chip BUT fell just short at 4951 MHz.

There's still work to do on the OC, so feeling reasonably confident that it'll do the 5Ghz next session.
