Warm 970 Evo Plus 500GB

[TheNaitsyrk]

Recently bought 1TB and 500GB models of 970 Evo Plus NVMe SSDs.

 

They run bit hot.

 

CrystalDiskInfo plays a melody when I open it and sometimes the one that has OS on it is at 52C idling.

 

Is that "normal"?

If they're anywhere near the graphics card, they're going to be in the way of the exhaust heat unless it's a blower style cooler.

 

EDIT: I see you have a water cooled video card, so there goes that.

52c is fine for a ssd, that won't hurt them and is far away from the thermal throttling limit. I wouldn't worry about it.

To be fair, my 1TB one gets hot too. And that one is not even close to the other one. I'm using top and bottom slot on the mobo.

Coming through again! Thanks.

These are extremely hot NVMe drives. I have the 1tb version as my memory controller was hitting over 100c when doing file transfers according to HWinfo64. I ordered me an EK heatsink for it and temps never get above 72c now on the controller. Here is a before/after screenshot from just running Crystaldiskmark.

Yeah, 960 wasn't that hot. I got the Plus version so that could be even hotter. Very helpful answer, thanks a bunch!

The irony with SSDs is NAND stores data more reliably at high temperatures, but the controller run faster at low temperatures.  So its always a balancing act but generally your data is safer at a higher temperature.

This only true for writing due to semiconductors being more conductive with heat. Data retention loss however, accelerates with higher temperature (http://www.ni.com/product-documentation/10126/en/#toc6).

Thus the balancing act and why you want cool idle temps and high writing temps.  Quite the dilemma.

I'd take idle temps over higher writing temps since I'm still writing to an SSD at a rate so slow, the drive is more likely to be "obsolete" than it is to run out of P/E cycles, where high write temps would help extend. Whereas high storage temps can render flash memory useless within days, at least that's the theory.

True, its why I decided to use the slot on the top of the motherboard with the heatsink for mine.  Its not like I need my boot drive to retain all data for 10 years without ever being rewritten.

I'm also a little wary about using the slot under the motherboard as the cooling there, in my ITX case particularly, is going to be lacking.
