I've an I5 and have almost never heard the fan and when I did it was barely discernible. Nor can a best buy be picked out without qualification because needs, desires, the willingness to compromise or balance between the needs and desires, cant be known by any particular respondent. I've been reading these forums for months and you respond to every single post where even remotely possible evangelizing the M3 which is OK when given as a simple presentation of objective fact but you presume to know what people need and want.
I'll give you a couple things to think about. When these things first hit I was at Best Buy when the doors open and outside of myself there were a half dozen customers and several employees playing with two SP4s, one an M3 and one and I5/8/256 and of course we began comparing them. When various drawing programs were opened up it soon became obvious that the I5 performed better with less lag, not huge but better. It also performed better with multiple apps open. I'm not talking about benchmark .0000001 better, I'm talking about noticeable stuttering with the M3 while the I5 was still chugging along.
In my previous post you might notice I said I would have considered getting the M3, that was because while it was without question a weaker part it was also not that much weaker and in most scenarios that I could imagine using the device in my day to day life would have been comparable in performance. But then it didn't matter, I need more storage than it can provide so it was never an answer for me. Even if it had the storage however I still wouldn't have bought it, I can afford to pay slightly more and enjoy the extra performance.
Before you start running on about your expertise you might want to be aware that I owned and sold my own PC company which is how I now enjoy the benefits of retirement. Then again I'm not nearly as smart as you are, I'm not even sure what I want or need sometimes, let alone what someone else should need or want.
