I used the push pins for a while. When I switched over to the bracket, my temps dropped about 3-6C. It's still a cheap cooler and even with purchasing the bracket separate, it is a lot cheaper than the coolers it is compared too.
Ah, I'm sorry. The Xigmatek should cost him around $45 total for the heatsink, fan and the bracket. I still personally prefer it over the majority of heatsinks.
