17 R4, heatsink upgrade?

Hi!

My Alienware 17 R4 gets very hot. I already changed the thermal paste and cleaned it, but it improved a little. I think his heatsink is very inefficient. Why have an i7-8720HK and have to run it at 2.9GHz playing, or Undervolting? At 4.3GHz overclocking, throttling. Temperature hits over 95°C and often 100°C.
Has anyone upgraded heatsink to this one?

Are you Overclocking? if you are just Stop. Turbo Boost is pretty much overclocking but it actually can control your frequency whenever the temps get too high or low.

Most games are GPU based and only require a 4 core and 8 thread cpu at minimum. So i found out that when I overclocked my Alienware 15 r1 to 3.7Ghz it made no difference whatsoever to my gameplay performance with a Overclock or not. I just undervolt and leave it like that.

 

Hope it helps.

Hi!

I found a post on the notebookreview forum about heating Alienware.

It looks like a chronic Dell problem. The heatsink has no uniform contact with the Die and causes overheating. This generates a very different temperature between Core 0/2 and 1/3. In my case, the temperature reached 95C on Core 0 and 80C on Core 1, for example. The problem is not overclocking or heatsink's inability, but the poor quality of construction and assembly.

I made some adjustments and got a better adaptation of the heatsink. It improved, but it didn't solve it. I made a temporary wedge in the heatsink with the back cover pressing the heatsink in the Core 0/2 region and now the temperatures have become lower. I mean, much lower! The difference in temperatures also dropped, about 3-5C between the Core.

Look:

Also I forgot to mention. You should put some high quality thermal pads on the heatsinks and the PCH.
