I have an i7 4790k and the temps are hitting 80degrees under a 75% load (This is the stock intel cooler). So I was thinking about upgrading the heatsink to the coolermaster vortex plus. Will this bring down the temps and can you please give me a rough estimate of how many degrees it will be better than the stock cooler. Also is there any better option around the $20 - $40 price range?
