are you just using it to run GPU? are you doing to overclock?
if it's just there to run the OS for GPU mining or you do not intend to overclock, the stock heatsink fan will be fine and is low profile.
i had that zalman for a AMD x64 processor; fucking huge, but quiet. this is a good cooler but you need more clearance in the case than you think.
Mostly GPU mining, but I may use it as a Plex Media Server. This is a PC where I'm piecing it over the next 3 weeks. Here's what I have so far
1. CPU: i5 4th gen (1150) cpu
2. M/B: ASRock H81 Pro BTC
3. Kingston 8gb ram (4x2)
4. Plastic Milk crate
5. 2 x PCI risers (ASRock Pro Kit)
I'm going to start with two GPU's (for now). Can you make a recommendation on a PSU? I see some 1000W that range from $150-400. The next phase in the purchase is GPU cards and PSU.
