Hey Jonah, Nice to see you again!
I am very happy with the performance of my 4" Hydrofarm (172 cfm) fan, and 4x12 Phresh Filter (rated for 200 cfm). I have been using it a little over 6 months, and I would say there is not even a hint of an odor. When it comes time for you to look at them - I think you will get what you pay for with fans/filters.
Your temps sound similar to mine, my humidity is a tad higher, usually floating between 40-50% humidity. Temps with lights on are low seventies, and I think around upper sixties with the light off.
That being said, my odor/air filtration cost me about $160 out the door - $90 for the filter, $60 for the fan. Oh yes, the ducting - got it for about $15 for a 20 foot run of it. So we are talking $175.
Could I have gone cheaper? Absolutely without a doubt- But I was thinking long term. What if I upgrade the size tent? Or add another? I wanted to have options. I am working with about 35 cubic feet - a 172 cfm fan is WAY overkill. I have all flaps opened and one port wide open and the sides still get sucked in quite a bit. I believe a fan controller would help with this.
The fan and filter are hung with zip ties to the frame, and connections are made with hose clamps, duct tape, and supported with more heavy duty zip ties. I cannot hear the fan because it is inside the tent, but more so from the air pouring out of the 4" ducting. Again, I think a speed controller would chill this out, or some kind of silencer. Not loud enough for me to worry though. If people are coming anywhere near or IN my bedroom, I could close the closet door and you barely hear it.
Safety and security should be the #1 priority when doing this- If odor has been noticed, or is a problem, I would definetly suggest getting a filter and exhaust fan combo. I mean, we all know it stinks - do you really want to be getting in trouble (if not medical) by the odor , when it is easily controlled? If anyone is reading this - ONA may help a odor problem or hide it but that's about it. There is no covering up flowering dank. If you are in a renting situation, there may be a time when an emergency takes place and staff/maintenance need to come in. Don't let the smell get you caught! This to me is #1, for your safety!
Lastly, when I was surfing the AFN for reviews on fans/filters - One of the last I read before making up my mind was a post by Muddy. If I remember correctly (and I am currently toasted) I think he said he was running two tents with his Hydrofarm, and has used it for years with great results.
Wish ya luck Jonah!
just curious whats your length x width x height?
Hope to hear from you again,
