below RM50?

i selling ball bearing fan size 120mm x 120mm x35mm dc 240 v with 2 meter wire n plug RM 50 each

make a shroud... it will focus the air into a single direction. make the outlet smaller so that the air is concentrated...

to concentrate the breeze flow so can lower temp.huuhu.

is it?

old chinese people say: got 1 good, no 2 good (有一好没二好)... depends on your ideas

upgrade to chiller la...

Just got home, searched all the unused chargers / adapters I have... most of it have input 220 / 230v but the output varies.

I have output of the following

DC 12V 250mA
12V~1A
9VAC 800mA

How do I know which is the strongest?

1A = 1000mA ampere bigger = stronger... but the fan.. wat rating is it? too high Ampere will fry the motors...

Haha, I really have no idea on electricity.. all my knowledge I haven given back to my teachers once I graduated f5..

Thank you Really owe people here big time for introducing so much to me!

I haven't buy the fan, just searched the adapters in my room last night.
I will play around this...

I have a question, how do you know that 12V~1A is AC or DC?
From the 3 adapters that I have, I know the first and third since it's written there DC 12V 250mA and 9VAC 800mA

What is the output of your adapter and the input of your fan?

Can't wait to DIY the fan and see the temperature drop to see what plants I can play with

What is the output of your adapter and the input of your fan?

I don't have good eyes, can't see it! Yesterday I went to a computer shop and they were selling fans, but I do not know how to see how good is a fan. Is it the rpm?

When I look at things, I tend to look at the expensive ones, but then when I check my budget again, the product will slowly drop in price too

I was checking this link and it mentions RPM, ranging from 2400 to 4500. Can I know how much RPM are the fans sifus here are using? Or its not a primary concern

7 purnama pon xkan abes citer pasal kipas nih.susah sangat, beli jelah kipas yg dah siap kat kedai aquarium. rm28 pon ada. aku gune kipas tuh. rpm dia pon ok gak. tsnye luqee. dia dah penah tengok da. cume bising sikit r. sendal r span kt tempat yg vibrate tuh. selesai. nk diy mcm susah bebenor.huhu.padehal, 1jam jer da siap.hahaha. don't makes things complicated lor. hoho

hehehe. what conductor that can make the water to decrease it's degree celcius when a fan concentrated to the conductor. any idea? means that the conductor touch with the water. this will prevent from water hydrating. don't think of keep the temp to 24c. 26-28 is good enough. the main achievement is minor water hydrates. this is better. isn't it?

so, this is busted method lor?ok. then, how come dolphin mini chiller that using fan can achieved certain decreasing celcius yah?

DIY chiller

u can DIY one, follow the link i gave above, but i calculated the price for its part before, the price is the same if u buy 2nd hand hailea chiller...sumore it is TEC bro...it is effective to certain extent only...it got limitations...
