how many of you keep your fans on 24/7?

23-05-2008, 08:24 PM

any one? just started using a fan yesterday for my cherries tank (diy-ed the fan clip but haven't do up the power part

)...

to my surprise temp actually dropped from 30 deg to 25 deg over about 6 - 8 hours! now hovering between 25 - 26 deg. pretty damn satisfied with the fan.

so yea, back to the main question... how many of you keep your fans on 24/7?

I do leave my fan on 24/7 but... result is not really fantastic. on a hot day it could be like 30 degree or a cool day 27-28degree.

can i know which or what fan you used? sounds like u bought each part separately. lol.

where you live? nowadays so hot, even with fan on 24/7 the lowest i can go for my tank is only 27.5c
what type of thermomether are you using?
i guess 25C achieved by fan during this warm period is rather immpossible..
maybe you want to use those mercury thermometer to get a accurate reading.

An aquarium fan that cools your water by 5 dgrees C is really amazing. If this is the case, there will no longer be a need to get a chiller.

It doesn't matter how many hours you leave your fan on. It doesn't cool your air temperature like that.

i'm using a thermaltake 80mm fan i bought eons ago for my DIY PC hobby last time. rating is 0.70amp (very very powerful for an 80mm fan). its noisy but works great.

yea i diyed using a ac-dc adaptor and a self-made fan clip.

live in bukit batok loh... i'm using a boyu submersible digital thermometer.. previously before i added the fan, temperature was a constant 30 deg. after i added the fan, the temperature hovers around 25 - 26 deg.

i don't quite catch the last part what you're trying to say. care to share and explain? thks in advance!

i think it means that he doesnt lower the temp that much

EvolutionZ · 23-05-2008, 09:42 PM

im sorry but i think digital thermometer are mostly inaccurate.. try to get those mercury ones.. i seriously don't think fan can acctually get a tank down to 25C..
somemore this few weeks so damn hot.

I went to a friend's office on a very hot Sunday evening, office no aircond since Friday evening and windows are closed and facing western sun so it was quite hot actually when I walked into his office. He is using a fan for his 2 footer I think quite similar to yours, surprisingly water temperature is 24C!!! reading from a sera analogue therometer. I didn't believe when I read the reading but when I put my hand into the water.... it was damn cold even glass surface looks cold covered by a thin mist

mine twin fan very powerful one 80mm fan for my 2ft also only at 28c
