Too many heatsinks

axescot · Sep 23, 2018

I'm working on a new build. The m2 ssd comes with a heatsink and the motherboard comes with a heatsink. Does it matter which one I use? The motherboard heatsink is much bigger. I'm assuming not to use both.

There is a second m2 slot which doesn't have a heatsink. Is one slot faster than the other?

M.2 drives can warm up with huge amounts of sustained writes.....but, they still dissipate about 10 watts max...

A little air blowing across it seems to go farther than a heatsink does, based on tests I've seen, where the heatsink even caused the tested M.2 drive to thermally throttle a bit sooner...

That seems odd. Here's an example where a heatsink reduced temperature by 20 degrees.

But now I'm thinking using the #2 slot because that would put the ssd under the video card, so the heat from the video card rises and doesn't go to the ssd. Is there a difference between the #1 and #2 slots, ie one is faster than the other?

When mounting a heatsink it matters its orientation, you want the air to blow "in-grain" like cutting a piece of meat in-grain to facilitate air flow, as long as this is the case, the bigger HS the better.
