I have now had my cooltube installed for a whole day :thumbsup:. I cannot believe how much it is helping out, it has already brought the daytime temps from around 87-88F down to about 80F, and i dont even have an active exaust fan going yet :thumbsup::thumbsup::thumbsup:. Hopefully after i get my inline i will be temp problem free. I also have to cleane the cooltube tomoro, since i got it kind of dirty and smudged up tofay, when i was putting it together.
