Btw,does thinner will do the job well if i cleaning thermal pads?

can, its stated 95% pure isopropyl alcohol on the bottle, depending on brand and free of additives, again depending on brand la smile.gif

Thats where you are very wrong there. Alcohol has high volatility makes alcohol tend to vapourise. Alcohol at high percentage is used as antiseptic and almost pure alcohol(>99%) is used as a cleaning agent. All alcohol burns and ingestion of above 50% alcohol would be enough to kill.

try putting anything more then 75% pure isopropyl alcohol on a wound and permanent burn/scarring is incurred smile.gif that is why max used is 70% and not 99%

All alcohol does not burn on its own. But all alcohol above 30% does evaporate when exposed to ambient (more then 0c) temperatures





QUOTE(tomatos @ Mar 1 2008, 06:58 PM)
Please la inhaling of 70% alcohol is also bad. Alcohol at 10% is also volatile. Vapourisation is due to it being volatile.

You don't need to go clubs for high percentage alcohol, just go make your own illegal rice wine. Ya they probably could go above 60%.

We are talking about cleaning compound here and you said 70% was the best which is totally wrong.

Well noone specifically asked you to inhale 70% alcohol from the bottle or from plastic bag right? Normal usage is fine(cleaning etc etc), hell even smelling it is fine, but dont do it excessively la,i wont be responsible for your PHD tongue.gif

its not because it is due to vaporisation that it is volatile. It is very molecularly light and due to that it cannot store alot of energy and hence its melting point is -88.8C (184.35 K) and its boiling point is 82.3 °C (355 K) and that is why, when its exposed to ambient temperatures it will vaporize as well as carry a fair bit of energy off the surface it was on, and when its on your hand, its even more faster (hence the cold feeling). What more if it is lit up from a heat? This is referring to Isopropyl alcohol la, where as other types of alcohol are more or less about the same melt and boil point. Isopropyl alcohol cannot be drunk because it has a toxicity almost double of those from beer/wine (lazy to explain), and that is why you can die if you drink it.


Illegal rice wine is composed of ethanol, which is of a different substance then "cleaning compound", and different charateristic and and that is the one from beer, wine etc etc, those drinkable ones made from fermentation smile.gif

For cleaning compound, 98% is the best, but can you procure it without going through a lab? Best easy to get and use is 95% priced at rm 5 per bottle brows.gif

Those artic cleaners are about 80% pure.

it could be due to the fact that thinner is corrosive, it dissolves even paint, so you can guess what it might do to your cpu. i know that nail polish remover is actually a little corrosive towards plastics, but with metals i havent seen any problems. i usually clean my laptops' heatsink and proc heatspread with nail polish remover and up to date havent had any problems. i only noticed that it eats plastics a little, depending on the brand.

PS just did some checking, apparently it eats silicone as well, so letting the nail polish remover touch any non-metal part of the cpu is definitely a problem. but i would think that if your cpu has a thermalspread, like an intel for example, it shouldnt be a problem. if you're using an amd, then if you have nothing else, just make sure not to touch ANYTHING but the die. same would go for thinner i guess. in which case, you're probably better off with a pure alcohol cleaner.

its due to acetone in the nail polish remover that plastic is dissolved as its a solvent, same stuff metabolized by your body when overdosing on beer/wine and same stuff as some paint thinners in the market.

Why have to care about thinner?Why it is not normal as Alcohol?Since thinner also contains alcohol
*
because most thinners you purchase from hardware stores are made from petroleum, and having a layer of oil/petroleum on your cpu/hsf is not good right? smile.gif




QUOTE(hypermax @ Mar 1 2008, 10:45 PM)
If i am not mistaken, the reason behind not using nail polish remover for cleaning CPU is because it contains fragrant oil, which is likely to trap heat. Correct me if i am wrong.

that as well smile.gif

well, 70% is easily bought in the form of alcohol swabs which is for easy to use ( tear package and use) i have used both before, they are practically the same just that 70% leaves a slight water residue which is of not much concern because its wiped off with cotton wool or cotton buds biggrin.gif
