M11X Heatsink copper mod in Alienware M11x Posted November 5, 2016 On 11/4/2016 at 4:48 AM, akeean said: Another neat non-hardware fix: Use msi afterburner in your current game to display per core cpu&gpu usage. Then once you got a feel for if the specific game is gpu or cpu bound, set a speed limit for the component that is not needed to run vs fast, to give more thermal headroom for the part that you'll run faster thanks to nvidia boost 2.0 / intel turbo boost. I have a gt740m and a i7 4700mq, most of the time the cpu is not that stressed, while the gpu is at 99%-100% in a given game. In that case I use ThrottleStop to limit my cpu speed to a multiplier of 24 (so it runs at the top base clock of 2,4ghz instead of boosting up to 3,4 ghz) this gives me enough thermal capacity on the unified cooler with dual headpipe to overclock the gpu by 150mhz to the maxmum possible in msi. afterburner and keeping each part at under 80c, despite overclocking&a noticable boost in whatever game I'm on. Gotta get myself some copper shivs tho and mod the heatsink.
