Heat sinks? Well, I do computer hardware reviews for a website and I currently have a number of them in my inventory. Let me know if you have anything in mind. I did cases last year. Sold all but one. As for fans, I have noticed how some will behave differently than others. So far the best ones I have used are the Cooler Master JetFlo fans. They are loud when they spool up, but they move a lot of air (95CFM).
I was debating on just getting like a 212 evo to toss in. I didn't know if a better contact patch/material would minimize the initial temp spike compared to the aluminum Intel cooler.
The jet flos are nice, but I'm a San Ace/Delta enthusiast. My gaming rig has 6 pwm AFB1212VH in it. They'll pwm from ~700rpm to 3100.
