Glad you got it workin bro , did you mount and unmount to check the spread/contact of the thermal paste?

Sure did. Thanks I'm very happy now. i think I will go down and get 2 gallons Antifreeze and replace 2 gallons of the washer fluid, because it's only rated for about -25F/-32c. It seemed to stop getting colder and start warming a couple degrees when the coolant got ~5c below it's rated temperature. May have been geling up slightly.

Tell me something...if the chiller is @ -30c, what would the digital probe I intend to put on the chip say approximately? Software says the chip hasn't gone below 5c...do you believe that could be true?

Well, thats why I asked about the mount, wanted to make sure you had all the cold on the IHS.

-30c at stock speeds/voltage on a QX9650 was in teh neighborhood of -15c if I recall correctly. The efficiency on this type of chiller setup isn't at all nearly as good as strapping a pot onto the processor, but its sure fun.

You can look to improvements in efficiency between the bath temp and the cpu temp by making sure the entire line of tubing is well insulated. If you've already taken care of that, don't expect too much more in gains.

Running a chiller on gpu blocks usually lets you see gpu clocks screeeeeem in comparison to cpu overclocks. Its a bitch to insualte tho

I'm using Ceramique and I'm sure it's on there tight.

I better get a digital thermometer and see for myself.

I'm hoping it's actually below zero........hey is it safe to crank it to 1.7v now?

a decent k-type thermo is a handy tool in the subzero game...great investment.

1.7v would be safe if you could confirm a subzero temp at the IHS level, until then I'd stay patient unless you can replace the cpu out of pocket

I think Kal mentioned a great suggestion earlier. Using this chiller for GPU's and a DICE/LN2 pot for the cpu would be seriously epic. Either way, thanks for sharing this with us.

Yeah probably someday I will do that too. Thanks for the advice.

More problems.........sitting there @ 4GHz typing and the system froze up and would not reboot. The light on the mobo says cpu is not initializing because it never gets past that light which is the first to light up.

I removed and inspected everything to find the paper towel gasket slightly moist, but nothing else wet at all. I thought maybe "cold-bug" but after warming up and reinstalling the block(which I did not turn on), I get the same result. I reset cmos, removed battery and unplugged for awhile.

Seems that my cpu just quit.

I may look for a cheap 555BE or something to see if it's actually the cpu. Anyone got an AM3 cpu for sale?
