Best way available would be to use Nitrogen cooling.  But don't take my word for it, ask them crazy Jap bastards.

Copper shims are used to prevent crushing the delicate cores on the Athlon XPs.  Actually that's what the rubber feet are for as well but those can easily be destroyed by wear.

Nitrogen? any link? so copper shim is just a substitute for the rubber?

Liquid Nitrogen.  Copper shims are better than the rubber.

i know, you have a link on liquid nitrogen?

liquid nitrogen is not readily available ....... i'm gonna try using pure alcohol instead of water ....... but your system have got to close to "air" tight when using alcohol ....... as it will leak easily heehehe just as i found out ...... currently testing for leaks ..... nde ko pa lagay cpu

here's my attempt at cooling ...........  AXP1600+(1.82volts Vcore) and EPOX 8K3A ..... running at 200FSBx8.5 = 1.7GHz  ..... MAZE3+black Ice Pro + pure alcohol + RIO600pump ............... idle temp 35-38C ....... load at 40-42C

i'm now running my XP1600+ AGOIA 0224 at 1.763ghz and 1.9Vcore ....... 196x9  ..... super stable na hehehehe idle 37-40C  load 40-44C    ...... temps depend on aircon ........ some of the fittings ...... i superglued to make a "airtight" system ..... as alcohol leaks easier than water ............. hmmmmm dapat siguro mag install na rin ako ng fire estinguisher hehehehe

alcohol?  Why use alcohol?  Water has a specific heat of 1.0, while alcohol is about 0.6



in terms of heat absorbing capacity, water is definitely much better... (I'd recommend that you use triple distilled water...



the only other chemical that I know of that has greater specific heat than water is liquid ammonia (about 1.15) but I doubt if the cooling system can handle its chemical properties...

danger den maze3 ----] padala ni kuya (nasira ko yung see-thru top heheheh pinalitan ko ng stainless steel top)

black ice pro ----] 2700

Rio 600 pump ----] less than 500 lang ata to e ..... me sale sa bangketa ko nakita sa g-hills papasok ng virra ..... 500+ lang yung pinakamalakas nila

clear tubings 10p/meter

a lot of patience



alcohol's viscosity is much lower than water ...... this makes it better at flowing and the best really i think is a combination of water/methanol ...... i will try again water/acohol combination ...... first try ko yun eh ang lamig nun kaso nag le leak pag me alcohol ........ it's molecules are smaller ata kaya kelangan "air" tight ang system mo di lang water tight



and i read an article also comparing both in actual test ..... and the alcohol won .... problem is it evaporates ..... so u better have an airtight system ......

alcohol evaporates easily ....... it accepts heat faster and dumps it faster as well ....... in a system using a reservoir instead of a radiator ...... water wins hands down ..... because it can hold more heat ....... but without a reservoir .... speed is the key ........ so far that i've noticed is my temps at idle and at full load (sandra's high stress continous burn in test) is like 2-3C difference only



remember when u were sick and mommy mixed water/alcohol to make punas punas you and to lower your temps ...... it's colder than just water

thats because alcohol is more volatile than water. that cold sensation is due to the alcohol evaporating off your skin.

I agree triple distilled is much better.

the best is "compressed" alcohol according to a physicist ................



alcohol performs better in the sense it's molecules are smaller than water ..... kaya nakakasingit sa mga cracks in the surface better than water does ...... it's viscosity allows it to flow smoother on the surface of the block than water ......... kung perfectly polished din ang inside ng copper block mo .... water will win

 whoa... says who?  water IS smaller than alcohol... compare their molecular weights... and their structures:



water is H2O : MW =18.015



ethanol is CH3CH2OH : MW=46.068



methanol is CH3OH : MW=32.042

 not exactly, there is a reason why water jackets are not polished... a smooth surface will cause water molecules to adhere to the metal surface, due primarily to its high surface tension.  If this happens, residual water molecules sticking to the surface of water jackets (copper block on your case) would not recirculate to the radiator... resulting to poor heat transfer between the copper block and the radiator.  As a workaround, engineers designed rough surfaced water jackets to create turbulence so that water would find it hard to stick to the surface... and still others decided to mix "water wetter" (a chemical simply designed to lower the surface tension of water without lowering its specific heat too much) to increase flow rate...



ALthough water has a high specific heat, which allows it to absorb great amounts of heat before its own temperature rises, this property also makes water lose heat slowly.  To work around this, engineers would create a large radiator to allow more surface area for the water to get in contact with so that it will loose more heat before it is recirculated back into the water jacket...
