gotta buy air pump~

I prefer Whisper also.
 
I >HAD< a whisper running on my 55. It was kept inside the stand and I couldnt hear it at all unless everything else was dead silent.
 
I use a Rena, but the rubber feet fell off, so now I wrap it in many layers of toilet paper and you can barely hear it. So I think any good airpump would be fine, and all you need to do is wrap something around it and it will stay quiet. I haven't had any overheating issues
