How much does bong performance drop with high humidy?

[Illah]

It's not that humid in my place, but let's say hypothetically that humidy gets to 100% (very unlikely, but sometimes it can rise when the fog rolls in), what would happen? Would the bong simply stop cooling or would it just work very badly?

no cooling would take place if the humidity hit 100%
also you entire computer would short out....
as it would be swimming in a pool of water :)

Basicly the bong works due to evaperation.....
And if the humidity is too high that the water can not evaporate, no cooling can or will happen. As all of the cooling power of the bong is in the evaporation. The evaporation takes all the heat with it, as it turns to steam/vapour.....

That is also why you generaly do not want to collect the vapour, as the heat would then stay in the system with no place to go, as (once again) the heat leaves the system once the water turns to vapour.

That's what I was worried about. I don't think it's ever been 100% humidity where I'm at though, it was more of a hypothetical.

Has anyone on here ever had some big problems with the humidity?

A bong will still work well in 100% humidity as evaporation is only part of the effect.Heat will still be transfered to the air,but the water temp won't be able to drop below air temp without evaporation.The temp will probably end up being around 2 degrees above air temp

Yeah I was actually just thinking that a little while ago... As the droplets fall they're still getting the counter-current of air from the fan at the bottom, it would have to do something. Almost like a regular HSF, just blowing air on it.

OK, good to know it'll work even in bad weather. SF isn't too humid, but when the fog rolls in I guess it can be, but it usually doesn't last all day anyway. Thanks guys!

then all you have is a odd looking radiator.
temps will be high

at high humidity, (really high) the bong will still work every bit as good as a good rad setup. no more than a couple degrees higher than it would if it was dry and evaportating like mad. i used mine for about 6 months. i could notice a small change due to humidity but it was so slight that i never worried about it.

If you define performance drop as decrease in the below-ambient
temps you can get away with before condensation happens then
take a look at this (http://forum.oc-forums.com/vb/showthread.php?s=&threadid=82580&highlight=condensation) chart.

In simplest terms, if there is no evaporation because the
humidity is too high, the bong becomes a radiator instead
of a chiller.
