00:19 Exaga> jnettlet: https://www.cnx-software.com/2019/03/29/clearfog-itx-workstation-ultimate-arm-developer-platform/
00:22 Exaga> oh forget that you've already seen it looking at the comments :D
06:22 jnettlet> Exaga: yep a very active thread. Was a lot of fun
10:01 Exaga> jnettlet: sorry i pasted the url after reading 3/4 of the main content
10:01 Exaga> then there's like a dozen posts from you in the comments :D
10:01 Exaga> talking about things that Einstein would struggle understanding
10:03 Exaga> the clearfog itx is grabbing attention so it's all good
10:05 Exaga> which reminds me... the 16 cores are cortex A72? this processor is of the "high performance" group of A-class cups and can get hot when under duress
10:05 Exaga> cpus*
10:05 Exaga> looking at the pics of the board on soldirun site there doesnt seem to be any mounting holes or slots for a cooler
10:06 Exaga> is that something you're planning to address on the honeycomb/clearfog itx?
10:07 Exaga> to be honest if i was using it you'd need to strap a glacier to the cores to keep it cool
11:11 Exaga> jnettlet: https://www.solid-run.com/webinar-layerscape-nxp-arrow-arm/#after_section_1 very imformative. thanks :>
11:27 jnettlet> Exaga: we have mounting holes and are currently testing thermal solutions. Generally our top choice will be a heatsink not much different than the one for the mcbin..maybe a bit larger capacity and then surface mounted pwm fans.
11:28 jnettlet> Right now are fan of choice is the Noctua 40mm variants just because they are quiet but still move a lot of air. Probably the 40x40x20mm variant will be the recommended solution.
11:29 Exaga> yes the noctua fans are very efficient and quiet. i have a couple of them
11:29 jnettlet> we are also looking at mounting solutions for cooling loops in case users want an almost silent solution.
11:29 Exaga> 40mmx10mm
11:29 jnettlet> we are using 40x10mm now and they need to ramp up a bit too much when the SOC is under load. the 40x20 should be fine though
11:29 Exaga> you know better than me, once a heatsink gets hot it becomes a radiator and then only active cooling will help further
11:30 Exaga> i have had endless issues with thermal limits on a lot of arm devices
11:30 Exaga> especially the rpi
11:30 Exaga> http://sarpi.fatdog.eu/index.php?p=rpi-cooling
12:22 jnettlet> If you can find them this is one of the best passive heatsinks I have found for SBC's. https://www.zalman.com/contents/products/view.html?no=567
12:22 jnettlet> unfortunately they don't make them any longer
12:26 Exaga> jnettlet: HAHAHA that's a bit big for my i2ex
12:59 jnettlet> you really don't need it for the iMX6 line, except maybe the iMX6Q if you are pushing it hard
13:06 Exaga> how hot does the honeycomb get under operation?
13:07 Exaga> i usually hammer all cores compiling
13:07 Exaga> and heat is always a concern for me
13:08 jnettlet> with a fan, not hot at all...like mid 60's, maybe 70 with an under powered fan
13:09 Exaga> 70'C ?
13:41 vpeter> I have one of those fans :)
14:29 jnettlet> yep
14:30 Exaga> that's a bit hot
14:31 jnettlet> for a CPU core? not at all
14:31 jnettlet> the SOC is rated to 105C
14:38 Exaga> hmmm i bow to your vastly superior knowledge on this lol
21:55 Exaga> jnettlet: i'm sure you get tired of people asking this. when is the honeycomb expected to be rolling off the production-line? rough-guesstimate-ish?
21:55 Exaga> trying to figure out how much time i have for getting the cash together
22:01 Exaga> and the biggest fanboy honeycomb website solidrun will ever see :>
22:02 Exaga> would be cool if half th onlinee slackware community bought one lol
22:03 Exaga> will be porting slackware arm to it, of course
22:03 Exaga 22:03 * Exaga dreams and dreams and dreams lol
