For your question N520 will be better than TX3
But I wouldn't go for N520. Since it has same price as Hyper 212 Evo while Hyper 212 Evo runs more cooler and quiter than N520 so I would recommend Hyper 212 Evo

He probably can't fit it in his case, so for
92mm height limit, the N520 is best. For 120mm, choose the 212 EVO.
Hello i measured my case width and it is about 160 mm but right now i cant buy stuff online. i know about the hyper 212 but i cant buy it online plus my cpu is overheating (about 80*c) and i need a cooler quick to get back to gaming
Oh yeah, sorry 92mm/120mm is the fan size. We need the height, which maktovic provided excellently.
The N520 looks like an excellent cooler and is definitely better than the TX3.
If you can do it though,
the Hyper 212 EVO does sound like a better option and would run cooler and would likely be cheaper, as well as quieter and overall better (http://www.tomshardware.com/answers/id-1732684/cooler-master-hyper-212-evo-hyper-n520.html).
If you can do a couple of days of no gaming, I think the Cooler Master Hyper 212 EVO (or even the Plus for cheaper) would do marvelously and would outperform both the TX3 and the N520.
Hope that helps!
