Acetone in water cooling system
Acetone in water cooling system
as far as I can manage to make it go overclock my CPU up to 5.2ghz.
I got 5.1Ghz fully loaded at 1.450v and 80 degrees.
Now that we have real numbers to work with...
Actual water is the best you can use. Outside of silliness, of course.
Is this just for a one-time screen capture of that number, or is it meant for everyday use?
I tried my best to reduce the value as much as possible so I could push my CPU to 5.2ghz. I achieved 5.1Ghz under full load at 1.450v and 80 degrees. Now that we have concrete numbers, what do you think? Is this for a single screen capture of that result or for regular use?
For that "once magic number" simply immerse your rad in an ice bath.
Be careful of condensation!!!

Except for that, you cannot use ACETONE.
Use only distilled water. Swap the reservoir for a huge bucket or fish tank filled with distilled ice cube water. The cooler the liquid gets, the more heat moves in, which helps lower the CPU temperature. At 1.45v you have limited options to adjust and maintain stability without risking permanent damage, no matter the temperatures.
As discussed, it's clear that nothing beats water when active cooling is used (like a chiller or LN2). Water can handle a lot of heat. That’s why touching water at 212°F hurts a lot, while handling it in a 450°F oven feels only slightly uncomfortable.
Water possesses one of the superior specific heat capacities among liquids, whether measured by mass or volume. Acetone and other organic substances fall significantly behind. LN2 performs well because its boiling absorbs heat at temperatures well below ambient under room pressure, though its heat transfer is still moderate. For removing heat near room temperature, hydrogen is the preferred choice—though it demands strict safety measures. If you seek a non-conductive option without heavy precautions, transformer oil is a solid alternative, but be mindful of its effects on plastics and rubbers. Phase change introduces another dimension, leading into refrigeration applications. FWIW, water serves as an excellent solvent, which is why we generally avoid materials that dissolve in it.
Pure, distilled water is what many of us have talked about...this serves as your ideal 'coolant' for superior thermal transfer.
Beyond that, you'll need to consider two main paths with water-based cooling: sub-ambient TEC/Peltier devices—either directly applied or via an indirect coolant refrigerator. It's worth checking out Bryan6's work on this topic; he's been exploring it for several years.
You could also adapt a standard window A/C system by placing the evaporator in a large reservoir, like a picnic cooler. This method has been used for my beer brewing fermentation and could work well for PC watercooling with sub-ambient rated glycol. Using only water will cause the evaporator core to freeze solid, achieving very low temperatures.
Check your temperatures – are your chips functioning properly? This might be the most effective step you can take right now.
I’m not sure how you came across the acetone suggestion...
