| well it hard to explain , but witte whase surely exprest by the Lnē . Lnē has a boiling point off -196°C or so , to get to that point u need to have a surten amount of Lnē . the stuff in cola (sugger , the stuff that forms gas dont know the name) in contact with Lnē make's it boil very fast at less Lnē . the controll is 2°C less controll but the heat absorption is mutch bigger , this what we need . becaus a quad puts out a huge amount off heat after 1.62vcore , normaal Lnē cant keep up and temps start to rise . the cola trick is a nice add , it whase found by a little fauld @ ZDnet when we benched there . little chunks of cola fall in to pot , there is where i saw what happed . so i did the same thing here @ my home and found out that it helps with high load heat out put . im really the finder of this trick so all credits come to me . if i get the WR in 05 il put out the trick on XS , im sure some will say that is allready know but if asked vince (kingpin) and no one did this . he will be testing it soon 2 no u guys know it so hehe

| so Coke is an accelerator for evaporating LN2 ? DId you spill some by accident to find this out?

| Indeed, Coke (like in Coca Cola ) really seem to have an impact on LN2 cooling performance. First you'll have take a small amount of coke and deepfreez it, then you'll have to break the frozen Cola appart into little chunks which are then trown inside you ALU/CU cooling tube. Then add LN2 and do the regular LN2 benchmarking stuff... What would be the cause of this? I don't think it's is because of a gas escaping from the coke-chunks, that way the effect would go away after a while which and on first sight that didn't seem to happen. Maybe it's because Cola is based on water, which on his turn can handle heat quite good and theirefore causes rapid LN2 boiling. Or maybe not, I'm no engineer In the end it's hard to judge for me if it really worked, because I didn't compare with or without Coke added, though there was not much swing between idle and load which I though was a real problem when benchmarking with LN2. Also, if this trick does work, this would also mean that there wold be a optimal LN2-Cola mix for each kind of tube. If you're bored you know what to do |

| lol yeah temp swinging , one thing u can be sure temps only go down this way . 4.8ghz 06 and i got to low temps and hitted coldbug . geoffrey i dont think there is a exact amount of cola/LNē mix , but i know that u dont have to use mutch . hope to see u playing around with LNē soon bro , give me call if u need the dewar

| il be shutting down the contest for now untill sunday when i and massman benched . have some bad and some good news . air liqued in aalter is closing from this friday , but the good part is that thy give me a number from where i can get LNē from now on . beernem is 1 mutch closer and i can get all evenighs after 5pm , hope the price will be the same .
