reference vs custom coolers

[mattjackson123]

i will be buying a new graphics card soon, most likely a gtx 970, and have heard that the reference single fan design is far better for cracking that the custom multi fan design. From what i have heard ( pls correct if wrong) is that reference cards run hotter and louder than custom designs. The card will be primarily used for wpa/wpa2 cracking, as well as some hashes here and there. I am wondering if it is essential to get a certain type, and also if a certain brand of card is noticeably better than the others

Reference cards do not run hotter, no. They run much cooler, but usually are louder. However, hashcat is far more important than your delicate ears, so...
