Hi, thanks for posting your water readings. Nothing seems to be too much out of line.
The bacteria that deal with the water chemistry haven't had time to establish fully, so your Nitrite reading is a little high, although the NitrAte level will go down with a 20% water change (treated water, of course)......
If you could post your results daily then the reading will hopefully show a healthy pattern in their subtle changes.
Your pH is nothing to worry about unless it goes above 8, (but any big changes in pH would indicate a potential problem.) It can be gently lowered naturally if need be.
Is there anything 'living' in the tank, at the moment? ie. to provide an Ammonia source? And any live plants, also?
In addition, have you checked the readings for normal tap water, and (day old) tap water (at correct temp) after its been treated with de-chlorinator but before going into the tank?
You'll only have to do this once, but its worth making a note of.
I can't advise on fans, but just remember that electricity and water don't mix, so make sure that any fan you use can't accidentally be knocked .......
PS. This is a great article about cycling the tank
