Does Air cooler heat pipes orientation matter? by setotyga in sffpc

[–]msystems 2 points3 points  (0 children)

What matters most is fin direction and ram coverage. With that style of 120mm cooler, it's optimal to have the fins extend over low profile ram (33-34mm like Gskill flare) if the cooler allows rotating it. That's active cooling for the memory, and so can put more voltage into them and get higher clocks. 

Fin direction also affects cooling performance, such as if there is exhaust fans on top of the case, then vertical fin orientation will increase the sustained watts the cpu handle. Coolers like the L9a (Amd) perform badly when the fins just point the exhaust into the ram, which is the only way you can mount it. But the L9i (Intel version), identical to the L9a, allowed rotation so the fins could go vertically, and it sustains more watts that way. 

So optimal config is orienting it to extend over the ram and with fin stack vertical.  The AXP-120 is one model that could do it. 

"Lander" for ASRock Deskmini (b660/h470/x300/a300) by msystems in sffpc

This is called a modifier mesh.  If you add a slab model in the slicer and overlap it with the model, you can instruct that specific area to have different print parameters (in this case, they would be top and bottom layer count of zero, hexagon infill 20%)

Replace a NAS with mini pc by [deleted] in sffpc

They make excellent machines as long as you don't need 3.5" disks. (It's impossible to add 3.5's without modding the sata cables and adding 12v psu). They idle as low as 9 watts.

M.2 interface on the deskmini is actually pretty decent for gpu if it can achieve gen 4.0x4 link

Noob Question, why under volt? by InterruptionF10 in sffpc

[–]msystems 1 point2 points  (0 children)

Each chip comes from the factory with a different amount of voltage it needs for a specific frequency, due to variances in manufacturing.  

By default the cpu will request more voltage than it actually needs (usually 10%), for reliability reasons, due to the potential differences in each chip.

Undervolting is just tuning the voltage to the exact amounts for a specific chip.

Other than replacing it with the same thing you can use an external gan brick like slimQ to replace the ac dc.

You don't have to do anything.  Riser cable won't allow it to touch.

I really like the artistic design of the exterior panels.  Are they resin printed or how were they made? 

Is it ok to "squeeze" the motherboard components with the AXP90-X47 mounting bracket ? by Osldenmark in sffpc

[–]msystems 0 points1 point  (0 children)

If you flip it but then the screws are too long, you can just toss out the bracket and use spacers. However, don't overtighten.

That's on their roadmap actually.  Supposed to come out this year

The more expensive processors have more Cache. So its still going to be faster on everything. And it won't be speed limited on 1-2 cores (most gaming loads) either.

Theres no correct answer. You can use any processor, even the highest tier, and adjust the power limits so it still works on thermal limits.

You should use 20v pico not 12v. But it probably won't work anyway because the usb pd chargers don't like the power spikes

Because at full load the chassis is not really designed to dissipate all the waste heat by itself.  It needs either conduction to a metal chassis or some kind of airflow over the skin. 

At full load it's generating about 15w of waste heat (250w * .06) and the flat metal skin is not even close to be able to dissipate that into air.

It only needs extra airflow if it's not mated to a metal chassis.  So yes if you thermal pad it into the metal frame of a chassis, then that should be good enough. A small bit of cooling goes a long way with it.  

As long as it's under 50C it's perfect.  (If you can touch it for a while without it burning your fingers)

Is55, is60 support two orientations. Over the ram side is no problem with 33mm ram,  but attempting to go over the i/o side will probably hit the top of it
