Should I use the ASRock motherboard heat spreader for WD Black 250 GB?


Hi community,

I’m building a new PC and bought an ASRock B365 Pro4 and WDS250G2X0C (the small WD Black that comes without heat spreader. Now this motherboard has its own heat spreader over one of its 2 M.2 slots that they call “M.2 Armor” and I’m wondering if I should put the SSD under that or use the “open air” slot instead.
The motherboard heat spreader is made from aluminum and has some sort of rubber as contact material. The WD NVMe has a sticker on top though, so it was probably not designed to be used with an external heat sink. Yet I’m wondering what’s the better option in terms of longevity and or performance.
Thanks in advance!

P.S. Both slots are PCIe3 x4.


To answer this, WD support gave me the advice to use the motherboard heat spreader as is after judging the pictures below:

(The red circle is where the heat spreader goes. The right side shows the the WD black currently seated in the second M.2 NVMe slot.)

As for the sticker on the SSD, unless you made your purchase in the USA and benefit from last year’s FTC ruling you will lose your warranty the moment you remove it and some retailers will also state so in the fine print. So the decision is yours, but as a EU citizen I must leave it on no matter how it conducts heat.

Hope that helps!

Best regards,
