Subject: Z390 Pro4 and M.2

Z390 Pro4 is running with a Samsung M.2 SSD in slot M.2_1.
When I insert a second identical SSD in to slot M.2_2.... the temperature for the second drive is much higher than the first drive. Both drives are identical and both have copper heatsinks. If I swap the drives, slot M.2_2 is still at much higher temperature.

What is causing this? My PC case is very well ventilated and temps for CPU and MB are low. Now, I've noticed that the second M.2 slot is located right next to a heatsink with an 'AsRock' logo... which gets pretty warm. Is that causing my M.2 SSD drive to get so hot?

The proximity to the PCH heatsink could cause higher temps on that slot yes. That
said, it depends on how much hotter. As a general rule I try to keep M.2 drives
no hotter than 50c. If your temps are higher than that, see if you can improve
the airflow in that area.

@ Xaltar,
Thank you very much for your response.

Is there a way for me to replace the factory PCH heatsink with a upgraded version??a more effective aftermarket type that would dissipate heat quicker?

Generally speaking, I have never seen any benefit in changing the stock PCH heatsinks.
You can find aftermarket heatsinks that have more mass and will keep the PCH a
bit cooler but most will impede expansion cards or foul on board components.
Space is limited and height is restricted by the PCIe slots.

About the only "upgrade" that may help (a little) is replacing the heatsink with
an identical sized one that has more fins, thus more surface area.

Also, bare in mind that if you are using a downdraft CPU cooler (fan blows down
onto the motherboard/CPU) this will be helping the temps of the top SSD.
In other words, some of the temp deficit is coming from the improved airflow
over the top slot. Airflow around the CPU socket is typically better than most
other areas in the case by design.

In my system my triple fan GPU pulls air directly over my lower m.2 slot and
keeps it nice and cool. To facilitate better thermal dissipation you need to
effect one or both of the following:
Surface area
Airflow

Airflow typically provides the best results.

@Xaltar

Many Thanks for some very valid points... I am making some changes (Air Flow) based on your advice.
