Even if I haven't OC'd the NB frequency? Or should I OC the NB and add voltage to the cpu/nb?

[Neuromancer]

You were running HTlink at 2400 so I hope you are overclocking the cpuNB (it must be higher than HTlink)

1.575 on NB is a lot unless you are pushing past 3GHz on it. (Not really sure of required voltages for those kind of speeds TBH... doubly so on thuban)

[ny_driver]

I'm on a Deneb, but either way I never had the NB lower than the HT. Usually keep the HT below 2400 and the NB ~3GHz, but I tried it with both on "auto". For 3GHz NB I need ~1.51v

EDIT: will try again later.

UPDATE: I did a major overhaul tonight. I put the pump, and the feed line below the top of my reservoir, so the system is now gravity fed with no place for air to get trapped.

I'd say I have gained quite a bit. Right now the BIOS says the cpu is @ 5 Celcius and the reservoir is only @ -15 Celcius. Until now I have had to have the reservoir @ -32 Celcius to even see 5c on the cpu according to the BIOS. When I had the reservoir @ -45 Celcius this morning I actually saw 0 and N/A for the cpu.

Anyways I am expecting it to get much colder. And I'll post pictures tomorrow after I clean up the mess. Looks like a bomb-blast site when I get done doing a project.

^dont believe your bios temps past 0c they are wrong

[ny_driver]

I made it too flammable and ended up diluting it by taking out 2 gallons of the mix and replacing with water.

I think I need a higher flow water block or something. Even with the system gravity fed, it's just not flowing like I want.

flamable?

[ny_driver]

Yeah, alcohol is highly flammable and burns very hot.

What is the ideal mixture of fluids for a chiller? Obviously should have asked this question prior to now. I took out 6/7 gallons of that mix and replaced it with 6 gallons of anti-freeze/washer fluid. Now it is non-flammable again and I have some super high potency washer fluid in the garage.

Good thing I love wasting all my money.

I may look into a new pump and high flow water block. I plan to continue to use the chiller for 24/7 even though it's never anywhere near 24/7.

And finally...I think the pump is on it's last leg. At least I'll be an expert chiller builder by the end of this.

I never wrote down my mixture and it took some experimenting to find teh ideal mixture for my pump/setup/needs. I too have wasted a ton on the chiller experience

Didn't know you were running a flammable coolant this entire time, eek, glad that didn't turn out crispy

[ny_driver]

I was only running flammable denatured alcohol today for a short while. I soon removed it and decided the real problem was the block.

It came with the Swiftech h20-220 Ultima Extreme kit, but it is designed for a low volume system.... certainly not with a 3 gallon per minute pump.

I did a lot of stuff today and took quite a few pictures which I'll try to get to tonight. I opened up the block, removed the inner o-ring, drilled out the inlet hole to match the size of the outlet, and cut 4 grooves in it to allow more water and it worked like a charm.

Now if the Chiller isn't full the return coolant shoots right through the evaporator which is about 3 inches from the side of the cooler on that end.

I'm pretty psyched to see what it's like in the morning when starting @ -45 Celsius.

Definitely better already and my pump no longer sounds like it may die soon.

EDIT: I just realized I have been mis-spelling Celsius for awhile now.

Be back soon with some pictures.
