If you can stay 50c max then its awesome.
Is anyone else understanding this? 62c is "the point where it gets little hotter" and it is the warning point "where the heat starts"? If I'm not mistaken, the heat has already started way before then... You know, because it is a constant variable, and heat doesn't just "start" anywhere.
I'm not sure where you are getting your information, but as far as I've ever heard there are definite reasons they don't want you exceeding the max temps. The foremost one that I can think of is that like all electronics, CPU's function more efficiently at lower temperatures. What this means is that as the temps increase, the voltage required to support a given clock speed is higher. As voltage increases, so do temps, so you can see if you kept doing this it would be a vicious cycle with more and more voltage being required to keep the same clock speed.
The problem is that electron migration starts to happen once voltage is increased too much. And to be short, electron migration is how processors die from overclocking, as the transistors inside basically stop functioning as they should. And before they fail, they also require ever more voltage to keep functioning. You can see why that is bad.
However, you are correct when you say that it won't break immediately when you hit 62c. There is no magic temp number that things break at
I don't claim to know everything about why the max temp says 62c, I just know enough to personally not feel like tempting fate and going over the max recommended temp, or voltage (1.55v).
Also, my 720BE has been kept nice and cool by my old Xigmatix 1283, so pretty much any tower cooler will help you out. If you have small amounts of room in your case you could also try something like the artic cooling freezer 7 pro (an old one but performs well). And like others have said, the 212+ is an excellent cooler for the price.
Good luck man, and let us know how its going
