I didn't want to lock my GPU in place with water cooling.... so I just needed a unit large enough to do my CPU. Its a very nice size (like a wide mini-tower case) and quiet.... much quieter than any of my graphics cards cooled at 100% fan speed.... they sound like dust-busters from hell!!!

The load temps during this test stayed stable over the entire test. No real drift up...

I'll look at OCCT... but I am more than happy with RealTemp running in the background.

Is there any reason why you tested for such a short duration (169 seconds)?
During the test, the CPU core temperatures stayed stable and I suppose this is because the 2L coolant was still absorbing the generated heat while its own temperature rose from 18C to 19.5C. If the test was prolonged, coolant temperature would defintely rise above 20C and this would trigger on the compressor.
I think it is more interesting and important to see how your chiller system handles the heat from this point onward. Can the compressor handle a constant heat input? So far, this is still unknown.

no its not unknown i have saide it before his 85w chiller will die rather soon pulling a cpu that puts out 2 times as much heat as the chiller can move

if anyone wants to go into tank chillers they should look at 200W+ rateing to run 24/7

I have had it up and running for two nights now. Ran just fine for the 3 to 4 hours of use each night and each night I was targetting the upper limits proc freqs, using vcore voltages based on my previous experiences/proc temps.

The 'longest' bench I have run is 3dMark Vantage... which puts out a LOT of heat on the proc tests after 5 to 6 mins of full on multi-threaded gpu tests. I have watched the loop temps DROPPING during the final cpu tests after the compressor turns on. It can handle FULL cpu heat output....

I now need to step back and be patient. I know I can run previous stable proc freqs at MUCH lower vcores. When I find out how this new temp range impacts on vcore volts, I will do some longer benches. Right now, I haven't seen anything to suggest this 300W baby can't manage the 160W output of my proc... but I'm not going to jump into longer benches until I am ready.

Hi Shurik,

As I mentioned a few posts ago, I replaced my 85W peltier unit with a 1/4hp (300W+) compressor this weekend. Like you said, it is MUCH better...

if u got 300W then ur all good u dont need the rad just set ur temp to like 20c and make the chiller do what it dose best

HC-300A is 1/4hp which is 180W? How does it become 300W+?

From what I have read in the net, it seems to me the general consensus is to use 1/2hp (minimum). I have not seen much actual test data supporting this figure and this is one reason why I am interested to see how a 1/4hp chiller performs.

yes u are right 1/4hp is about 180w but thats the motor the chillers watage depends on the condensor 6x6 inch doubel row condensor can move 250w+ of heat

if ur building a direct on die evap phase to go sub zero 1/2hp is king

but for a chiller that dosent go sub zero 1/4 is more then enoghf i am actuly looking for a tiny 1/8 hp copressor to build a small sub ambient system just for a cpu to go 24/7 and not pay crazy power bills

Everything I have read about the Haelia HC-300A suggests it can provide between 280 to 380 Watts of chilling.... providing heat is often more efficient, and the 'heating' rating can be higher hence the estimated range for cooling, and the name: 300A.

Not sure exaclty how much 'cooling power' it provides in Watts... but this 1/4 hp chiller it is MORE than enough for my CPU at very good speeds and high voltage.

I had very low humidity last night and pulled the system down to 12C under load no problem...

if ur pulling down to around 12c get rid of the rad cause at that point it will put heat in the system by makeing ur water room temp or atleast turn the rad fans off

how cold can it go ?
