Got Haswell? You might just need a new power supply then. Check out the new Coolermaster V850 - this PSU has FDB fans which are supposed to be extremely cool and quiet. The V-series uses a fully modular cable system and is any colour you want, so long as it's black. Cabling is done with the extra slim flat-ribbon type cables that are so popular with circa 2013 chassis. This makes cable management a breeze and results in nice looking clean builds with the best possible airflow.
