So, I want to start by saying I have used arctic silver 5 in all of my builds for years. I only recently started playing with their ceramique, and would love feedback on which is better. I have not had issues with it other than this one time. I have a gaming laptop that I rarely use. I was working on the loop on my desktop so I fired it up and was playing warframe. I got an error screen from warframe indicating that it sensed that the computer was overheating / having issues. When I ran the montior program to look at temps my CPU was over 90 deg C! I had redone the paste and done some other work on it (I think swapped out wifi card) about 8 months ago, and it had pretty much been sitting since. It had quasi ok temps at rest, but they spiked quick when I tried testing it by gaming again. So, I ripped it back down and this is what I found when I took the heatsink off. I don't recall if this is a tube of arctic silver I bought from microcenter or off of amazon. Thoughts? I put a thicker layer and tinted the heatsink this time, the CPU will get to about 85 and level off gaming. Still high, but its a laptop with a baby cpu chip and I read that those get high. The bigger of the two is the GPU, and it stays cooler than the cpu does. Does arctic silver go bad? Too thin? Possibly fake product? Any thoughts?
