Ok, I'm Chilled. I'm Chilled. Relax....56K Warning!

nice setup man.

im just curiuos tho at your 920 @ 4.1 @ 68c,that does not sound all that good,no offense.but ppl can get that on regular water i suppose.i dunno??is that screenshot with the cpu loaded(primed,occt in the background?) i missed somewere.or is that good for a 920 at 4.1 on chilled water???.


and why are your volts that hi?they needed that hi?
guy below in the link i pasted is it D0 at 4.0Ghz (1.3v vcore)

if u clik the link and clik thermal specification it says 67.9 for 920,s????

I had my chiller setup similarly, boy did it rattle like crazy resting on that 2x4.

It's really not all that loud considering that it's a low end air conditioner. There is a slight rattle when the compressor is on, but it's nothing obnoxious. The fan runs 24/7, and when I go out there I pretty much have to look at the killawatt to tell/verify that the compressor is running....not just the fan.

nice setup man.

Just to point out: I'm not sub-zero, I am sub-ambient. Most folks go sub-zero with a chiller, so others see "chiller" and automatically think "sub-zero". I'm currently running water that is 63-68F/17-20C.

I think the main reasons for the temps and volts are:

1) I'm still running on an ApogeeGT Water Block. It's a bit out-dated, but I picked up a couple of holddown plates a few months back from Duniek. Trust me: A heatkiller Cu would drop that temp a bit. But with 3 rigs on the same WCing system--I have to be aware of block flow/restrictions. Mixing and matching blocks can wreak all kinds of havoc.

2) It's a C0/C1, not a DO. So, it doesn't OC as well at the same volts.

3) It was a fairly new OC and could still use some "tweaking". In the past: I was at 4.0 for a short while (few days). Ran 3.8 for 2-3weeks until I knew summer temps where going to force me to lower the OC for the summer. So, I moved it down to 3.4 for a week or so until I got this chiller up and running. Then I went back to 4.0, and then up to 4.1. Checked out 4.2+ and decided that 4.1 was good enough....at least for now. I'm not an OCer. I'm not a Bencher. I'm a Cruncher (Boinc: WCG + GpuGrid) that stumbles along in the OCing world. That said:

4) The volts are set at 1.38 (?). But go up to the 1.424 shown when under load. Truth is: If I could remember, or even knew, what half of the bios settings did....I would do a bit better. I'm not totally clueless, but I could definitely use some "growth" in that area. From what I have gathered from looking around 1.36-1.39 is not unreasonable for 4.0 C0/C1. Maybe I'm wrong.....

5) This i7 is a 24/7 cruncher and my everyday rig. I prefer (usually) a bit more voltage so things are "snappy" and respond well. I don't like limping along on the lowest voltage that I can get by with. Why it moves itself from 1.38 to 1.424 under load--I don't know. But the 1.424 was the same at 4.2+......

Well, that confuses me. I've always thought that the thermal specification would be like the high-end "safe" temp...or limit. But my understanding is that 90C is the new 70C (1366 v 775), and that quote seems to have something to do with: Intel Thermal Monitor’s automatic mode. The whole purpose of this chiller is to maintain what I consider a reasonable OC at a reasonable temp (70C or below) 24/7 throughout the summer. So, maybe somebody would care to breakdown what that actually means for me?

Ok, I read it, and I'm not sure what you are getting at..... , but here's the full quote:

I have a D0 at 4.0Ghz (1.3v vcore) and I hit just over that running OCCT with a large dataset, high priority, hyperthreading on. I max at about 86C in OCCT, Coretemp reads it at 83C. Idle I'm around 53-55C OCCT, Coretemp reads it at 50-53C.

For some reason Coretemp(and realtemp) register my temps 3C lower than OCCT does.

I run perfectly stable, not sure how you can get a 4GHz OC, even with a D0, and not go over 70C full load.

Emphasis added.

I've not checked out OCCT. I OC for 24/7 crunching stability and on this i7--I also use it for everyday use. As far as temp readings--which is right? Realtemp seems to be the standard, with Coretemp = or a close 2nd. Then there's Everest, OCCT and what else? I go by Realtemp with a 100 TjMax as I think most do these days. From what I can gather those guys are referring to air, not water. But the last statement sums things up pretty good: It's not easy running 4.0 or above under 70C.....and again: I'm using an ApogeeGT block--that says a lot.

Thanx! It was a lot of fun. I definitely learned a lot about the functionality of it all during the process. Sad to see it go, but I've moved on to this chiller..... But No Fear--I am keeping the car rads for now, because: I have a Plan....



A bit of an update:

Putting the tubing over the temp probe seemed to help, but only some. Ambient temps in the out-building directly effect the mechanical thermostat, so when temps outside (/in the out-building) get below the set temp--the mechanical thermostat shuts the compressor off and leaves it off. I've thought and thought, tried to insulate the thermostat, etc. I have quite a bit of experience from my +30yrs dealing with reptiles, aquariums, etc. I cannot see any reasonable, simple way to overcome this. So, I went ahead and bought 1 of these:



Ranco 111000

I looked at the Johnson Controls. I have a couple of Helix Proportional Controllers, but they are Proportional, so they won't work in this situation. Anyway, the Ranco have been around for a long, long time. They are used by zoos and aquaruims worldwide. Many, many animal keepers (public or private) use them. Convenience stores, restaurants for their coolers/freezers. In all: they are tried and true. Very reliable units.

They offer heating or cooling (not both on single stage), temp range from -30 to 220F, and a Differential range: 1° to 30°F.

They are designed for use with resistive loads (motors) and will resolve this issue 100%. The differential range will allow me to set the temps at which the compressor kicks on and off. With the mechanical thermostat it's 5F. Now I will be able to set it anywhere from 1-30F.

I'm hoping it gets here this coming week. I did not buy the wired shown, so I need to pick up the wiring, get it wired up and installed. Until then: My water temps are 63-68F and humidity stays ~50% in here, so condensation starts forming at about 84-85F/30C in here. I'll have to keep the A/Cs running until I get this setup. I usually turn them up to 82F when I'm not here/working. The ambient right at the PCs goes up to 85-86F which is too high=condensation.

Fingers crossed on no more major issues between now and then....
