    Hello to all.

    I recently purchased the Samsung 970 evo plus 500 gb NMVe ssd.
    its working great, but the only issue I am having is the temps.
    I dont know if it normal or its overheating.
    It idles at about 55C and during benchmark it reaches 75C.
    Is it normal or do I have to get a heatsink something like this to cool it down

    I know that flash memory degardes overtime if they write on the cooler side, probably below 40C.
    Any suggestion is welcome.

    but I have read that flash memory on the ssd needs to run warmer otherwise it will degrade overtime if run cooler temps, below 40c.
    I am worried during the winters, with the heatsink on, the temps will fall way below 40c at idle.

    I haven't heard keeping them cool degrades them? Quite the opposite AFAIK. A HDD in cold temps could affect it, not an ssd.

    Heat degrades electronics over time.

    It's important to keep the controller cool. This is why my laptop included thermal pads that partially cover the SSD, it's meant to be installed on the front part where the controller is. A heatsink for a m.2 stick will not degrade the life of the stick, and will help keep the controller cooler.

    That does not matter.

    Early NAND had the chance of losing retained data when stored over a couple years without being powered on.
    Newer NAND is much more robust and won't 'leak' data as easily.

    Besides how often do you leave an SSD powered off for years?

    So should I just cut the thermal pads in half and put it on the front part on the ssd..???
    I just Ordered these https://www.aliexpress.com/item/32953049535.html?spm=a2g0s.9042311.0.0.58914c4dfahTcO
    I will just put the half of the pad on the front part, put the heat sink on and put the silicone bands on the front part as well so that the back half of the heatsink doesnt touch the flash chips.
    I put my finger on the silver controller for half a sec and it kind of burned my finger, it was 57C in HWMonitor at idle.
    Then I turned up the front intake fans to max which are blowing directly at the ssd and it came down to 48C.

    While doing an online research I read that only the controller needs to be cooled because even at heavy loads when the controller reaches 70C, I touched the memory chips with my finger and they were only warm.

    Since you are installing to a desktop system, use the whole heatsink. In my case, the thermal pads touch the underside of the case, and the case becomes a heatsink.

    I've installed a Silverstone TP02-M2 larger heatsink on my 970 Evo Plus 500. The SSD was madly hot under benchmark loads, and in games even without any use it would reach up to 65C on the controller simply by virtue of being above the GPU. This is in a very well ventilated Meshify C with Noctua fans. In benchmarks it would reach 75C in Anvil and 89C after Crystal Disk Mark with the default 5x1GiB passes. I just couldn't stand these sort of temperatures on a new SSD.
    PS: mounting the heatsink increased Anvil score from 14521 to 16788, although this model seems to have some sort of issues with the Read part in tests, compared to what I've seen on the web. Here's the before and after temps, I would most definitely buy this again, the impact on temps is dramatic.
