Samsung 9100 Pro NVMe Gen5 Cooling: Motherboard Heatsink vs. NVMe Heatshield

Insights into benchmark results demonstrate how thermal management influences consistency and reliability in high-speed Gen5 NVMe drives.

When you compare two versions of the Samsung 9100 Pro NVMe SSD, you can see that they behave and perform very differently, especially when utilized in a Gen5 slot. High temperatures, like 94°C when under load, aren't good and can cause problems with how things work.

Anyone who wants to install one of these high-speed drives should compare the standard non-heatsink version to the heatsink-equipped version, especially when paired with a good motherboard heat shield.

Comparing the 9100 Pro with and without a heatsink

We wanted to check how the ordinary 9100 Pro without a heatsink would compare to the one with Samsung's heatsink. Many new motherboards have big, effective heat shields over their Gen5 M.2 slots. These could work better than the SSD's heatsink. Gen5 drives become hot, so if you want to keep the speeds you're paying for, you need to cool them down properly.

You can easily see the difference in size when you put a huge motherboard heat shield next to Samsung's heatsink. We wanted to see if this would really make things better in real life.

Test Setup and Initial Observations

We put the Crucial P310 drive in the operating system drive slot and the heatsink version of the 9100 Pro in the top Gen5 port. CrystalDiskMark and HWiNFO64 gave us information on temperatures and benchmarks. The drive reached 90°C when it was full.

More crucially, the read rates were limited to 12,000 MB/s, which is lower than this drive's capacity. An earlier test on a different motherboard showed faster speeds, suggesting that something was holding down performance.

We ensured the system was fully upgraded because write speeds were also lower than planned. After installing a clean version of Windows, updating the drivers, and updating the BIOS, we moved on to more changes.

BIOS Updates and Important Settings

The Intel 200S Boost is a new upgrade for computers with Intel Core Ultra CPUs. It enhances stability and performance without voiding the warranty. After updating the BIOS, we entered Advanced Mode, opened the AI Tweaker section, and enabled Intel 200S Boost to safely boost performance.

Samsung Magician also helped check the drive's health and set performance optimization options. The drive still reached 90°C and remained stuck at 12,000 MB/s read rates with low write speeds, even after all the updates.

Switching to the Non-Heatsink Version

To keep testing, we switched the 9100 Pro to a heatsink for the ordinary version and used the motherboard's bigger heat shield. We ran the same benchmarks again after formatting and setting up the new drive.

The read speeds stayed about the same at 12,000 MB/s, but the write speeds improved significantly and are now at the levels predicted. The decrease in temperature was much greater, which is more crucial.

The drive didn't reach 90°C; instead, it peaked at roughly 81°C and stayed below critical levels even after several benchmark runs. It reached 83°C in several runs, but that was still well below the heatsink model.

Compared to the stock Samsung heatsink, the motherboard heat shield performed far better in this configuration.

Additional BIOS Tweaks for Performance

You should look at the BIOS settings if the read speeds are excessively sluggish. To unlock the drive's full potential, you can manually update the M.2 slot to Gen5 in System Agent Configuration and then in PCIe Express settings, even if the drive is initially configured with a lower configuration.

Even though we couldn't reach 14,000 MB/s on this machine, the motherboard's heat shield's better cooling made a big difference.

Final Thoughts

When we used a high-quality motherboard heat shield with the non-heatsink version of the 9100 Pro, temperatures were lower, and write performance was better.

If your motherboard has a good M.2 cooling system, the conventional drive may run cooler and be more stable.
