First I want to know why all the stores near me label a can as "Compressed Air" when in actuality it is not air.
Specifically, they sell canisters that contain extremely flammable "1,1,1,2 Tetrafluororethane, Petroleum Hydrocarbon".
Question 1: Why do they call this "compressed air"?
Question 2: Is this stuff safe for use on hardware?
After using this canister for a few minutes and then coming back to it half an hour later, I noticed it got very cold and started to leak some water-like liquid from around the bottom.
Question 3: Why is it leaking?
I sprayed a ton of this into the heatsink fan of a Geforce FX 5800 that I am RMAing today. I noticed that it blasted a lot of the dust out of it but
there is still a whole crapload of dust piled up on the individual fins of the heatsink fan, and repeated sprayings have no effect whatsoever upon this dust.
Question 4: Why can't I spray that dust off?
Question 5: Is there any way to
get all that dust off?
Question 6: Are there any places that sell "compressed air" that is actually just compressed air and nothing else?
Question 7: Is pure compressed air safe to use on computer hardware?
Question 8: Would a portable air compressor be safe to use on computer hardware?
Secondly, I want to know if there is any sureproof way to keep dust out of my case. I don't want to use watercooling.
Question 9: Aside from watercooling, what is the most surefire way to keep almost all dust out of my computer case?
I'd greatly appreciate answers to all 9 of these questions.
