Hello forb1d, for small builds I recommend the 92mm Alpine 11 Plus CPU coooler w fan. Or the 5.88" heatsink USA profile with 140mm fan/s. Perfectdeal_US *eBay) has a great deal on 800mA drivers if you plan on running soft or you can use the Meanwell LPC-60-1400 if you want to run at 1400mA. If you can wait a month, perfectdeal_us will have some awesome 1.4A drivers.
