so that 970 pro is hot as hell. Maybe I do actually have a cooling problem.

not burn on contact hot but hotter than is comfortable to touch
Fireduck
2019-02-28 22:00:23
that's probably fine.
Clueless
2019-02-28 22:00:34
looks up the temperatures
Clueless
2019-02-28 22:01:03
yeah, that's definitely fine. SSDs can survive up to 85C, nice.
Clueless
2019-02-28 22:01:30
I think they also have overtemp protection.
Clueless
2019-02-28 22:01:33
solid state is wonderful
Clueless
2019-02-28 22:01:55
but does it affect performance?
Fireduck
2019-02-28 22:06:17
cursory searching suggests they have built in throttling.
Clueless
2019-02-28 22:06:24
I wonder if those things could be overclocked.

https://www.pugetsystems.com/labs/articles/Samsung-950-Pro-M-2-Throttling-Analysis-776/ M.2 drives like the Samsung 950 Pro can give incredible performance, but they can sometimes run hot enough that the drive needs to throttle the performance to stay under safe temperatures. To help you decide if it is something you need to worry about, we decided to benchmark a Samsung 950 Pro in a variety of M.2 slot locations with a range of system configurations to show how much a Samsung 950 Pro might throttle in your system.

use the drives based on the low power phison controllers, or the 960 pro - that was lightning in a bottle from samsung

10W is a lot of power to dissipate in something like an nvme drive
Rotonen
2019-02-28 22:17:46
and as they have chips on both sides, any cooling solutions are just for show
Rotonen
2019-02-28 22:18:18
what gets problematically hot is the side flush against the motherboard

Liquid immersion
Fireduck
2019-02-28 22:18:50
yes, 3M Novec, as the usual par for the course is
Rotonen
2019-02-28 22:18:59
or just mineral oil
Rotonen
2019-02-28 22:19:12
how do you cool the mineral oil?
Clueless
2019-02-28 22:19:23
giant radiators outside?
Clueless
2019-02-28 22:19:30
have the reservoir large enough
Rotonen
2019-02-28 22:25:27
ha, I might try it for fun
Fireduck
2019-02-28 22:26:32
plenty of material on youtube, dunno about equilibrium dissipation oil mass minimums for ambient temperatures
Rotonen
2019-02-28 22:26:54
but i’m sure someone has bothered to do such tables
Rotonen
2019-02-28 22:27:48
if someone is charting kg/W/K, they know what they’re doing
Rotonen
2019-02-28 22:28:12
it’s a gradient never the less
Rotonen
2019-02-28 22:28:51
and the mass/power bit should be an approximation, or utter madness breaks out
Rotonen
2019-02-28 22:29:50
but do not assume a person can lift the system after filling
Rotonen
2019-02-28 22:29:55
plan ahead
Rotonen
2019-02-28 22:30:00
odroid h2 is not big
Fireduck
2019-02-28 22:31:40
oh for that thing, sure, any freezerbox it fits into should do :D
Rotonen
2019-02-28 22:32:23
you’re still hamstrung by the pci-e 2.0 on that one
Rotonen
2019-02-28 22:32:36
i thought of immersing your R900
Rotonen
2019-02-28 22:32:47
ha
Fireduck
2019-02-28 22:32:53
it would make it quieter
Fireduck
2019-02-28 22:33:06
but I think that 750W of heat would be too much
Fireduck
2019-02-28 22:33:11
and the cavitation bubbles are pretty
Rotonen
2019-02-28 22:33:48
Wife: Why is there a giant tub of hot liquid glowing in the basement?
Fireduck
2019-02-28 22:33:51
i think you’d need a few cubic metres of immersion tank
Rotonen
2019-02-28 22:33:54
Me: Mind your business, woman
Fireduck

oil bubbles on a hot processor surface
Rotonen
2019-02-28 22:34:54
you still want heat sinks to transfer from the chips to the liquid, right?
Fireduck
2019-02-28 22:35:08
you remove the heatsinks and lift it upright when doing immersion cooling
Rotonen
2019-02-28 22:35:20
optimally even delid the CPUs
Rotonen
2019-02-28 22:35:30
wow
Fireduck
2019-02-28 22:36:01
no, just direct contact and the convection flow increases the contact surface area for you
Rotonen
2019-02-28 22:36:31
the middle man of a heat sink just slows that down
Rotonen
2019-02-28 22:37:15
air is a pretty good thermal insulator, so such indirect surface area trickery pays off
Rotonen
2019-02-28 22:38:45
https://green.blogs.nytimes.com/2012/09/06/cooling-a-computer-server-with-mineral-oil/ In a yearlong trial, Intel found that substituting oil immersion for the circulation of air reduced its energy costs by 10 to 20 percent.
