Ok sounds good. This batch is likely just fine, enjoy it!
If you are interested in better temperature control, do a quick search on this site for 'swamp cooler'. People are able to control their fermentation temps pretty well that way for very little money. I went a bit further early on in my brewing experiment, to a temperature controlled fermentation cabinet (fridge) (cost about $75, but I already had a fridge to dedicate to it). I can attest that this was probably the single biggest thing I have ever done to improve my beer. Steady temperatures within the range (a few degrees can make a difference) will do wonders for your beer.
Best of luck to you!
