I use a Cooler Master MasterLiquid 240 on my 1600x and it stays under 60c under load, and its OVC to 4.25ghz.
Tried to do my best to make one similar in price, but better components like SSD, More ram, and a better cooler. https://pcpartpicker.com/list/nFTHD2
Why are the pictures so blurry?
Should have went with the Acer GN246HL 24.0" 1920x1080 144Hz Monitor for less than what you payed for that dell and a 144Hz refresh rate too so it would have been the ultimate choice.
Nice i'm using the Seahawk X in my build too!
