So, there have been a number of proven cases where this SSD will thermal throttle within a minute or so of continuous read/write (Source https://www.pugetsystems.com/labs/articles/Product-Review-Samsung-SM951-M-2-Drive-703/ ). I want to know, whats the best passive heatsink you can find to slap on this? Just perusing ebay for some small, relatively tall heatsinks to tie on (Not looking for adhesive, want it to be in sellable condition afterwards), this is what I've found. I don't know the exact size heatsink that would be preferable yet.
Edit: This seller has a number of oddball heatsinks. Here are a few, as well as his store
Any aluminum or copper passive heat sinks should work fine. My personal choice is copper - just because - it's kind of like why do I need a CaseLabs chassis (?) Why do I need a water cooled system? Why overclock everything? Because I want to and can. Your choice to be "safe than sorry" is reason enough. I will put sinks on my SM951 simply to avoid hassle at a later time. Who wants to disassemble a water loop to put heat sinks on a drive tucked up under graphics cards and acrylic tubing? In my case, better preemptive than a reactive hassle.
