Here's the deal: I have a cramped mini itx build with minimal airflow (someone else built this system for me sadly) and my cpu (i5 4670k) is suffering from high temps (50-55 C idle, 85-90+ C load in some games) as a result. If the info is needed, my motherboard is the Asrock H97M-ITX/ac and my case is the Coolermaster Elite 130 Mini ITX. Because I have very minimal space to work with, my first priority is to look for something that is no larger than the stock cooler in terms of size (height and width!). So what you guys recommend as the best all around cpu cooler given these constraints? Also, I don't know much about thermal pastes and if it's worth to purchase an aftermarket one it in terms of its effects on temperatures. I'd love to hear your thoughts on that as well.
