M.2 drives and heat

Post by Ghostwalker » Tue Jul 24, 2018 6:33 pm

In a giveaway thread in general, someguyrb asked if M.2's benefit from heatsinks.
The thread is locked because the giveaway is over, but I wanted to thread the discussion here in case anyone was interested.

AFAIK, M.2 drives definitely benefit from additional cooling.
Puget Systems did a test on when heat comes into play with drive throttling back in 2016.
A quick Google search brings up more recent articles from Tom's Hardware, Linus Tech Tips, and (an oldie, but still a fave...) Anandtech.

I don't currently have a heatsink on my M.2, but what I'm wondering is, what if we take it another step from passive cooling to a liquid cooling block?
I wonder if there's some performance overhead to be had with keeping the drive as near ambient as possible...

Partially true. The controller benefits from cooling but the memory chips won't benefit and may actually perform worse if heavily cooled. So suffocating drives under covers is bad and full coverage coolers aren't necessary. Naked chips and a small sink on the controller seems ideal.

huh, I would not have expected that about the memory chips, not that I really know much about them. I do know that I have one that runs incredibly fast for maybe 10 seconds, then the heat catches up to it gets throttled, I had it in a laptop until recently and hadn't found a cooler that would fit on it under the shell, but now I should really start shopping for a sink for it. it's internal sensor says it gets up to like 120°c or something, it's known to be a particularly hot drive, (wish I knew that before I bought it for a laptop :P ) so I was also considering looking for some kind of active cooling for it now that I have room. Anybody have any recommendations (passive or active) for coolers? would it be better to get a bigger spreader, or just like one of those little stick on squares with some fins for the controller?

In the review linked below, they saw a 7 degree (Celsius) reduction in temps by using the EK M.2 Cooler. To me that doesn't seem like much. I actually have this cooler on mine, but honestly I just put it on there because it looks good.

I added a link above as GN just covered this topic. Basically if you are never going to write to the drive you can make it as cold as you want for reads. For writes the NAND should be hot. Controller heat is never good so sink those babies as much as you like.

Glad you posted the link. I saw yours at the lan and forgot to ask you about the cooler. I just got a 970EVO and am ordering one of these!
