Would that rather large heatsink work with the HiFiBerry on top without any danger of shorting?
I’m always concerned with heat buildup in electronics, but running in the 50’s is actually fairly moderate for most semiconductors. Certainly nowhere near the tragically bad cooling of an Xbox 360 or any Macbook for that matter.
I suppose some of the more CPU intensive synth engines (not the sample players) might drive those temperatures up to the point where a heatsink would be necessary.
That sounds like some sort of competitive challenge! Presumably you can rely on the Pi4 to throttle back if things get too hot? Perhaps the number of xruns will increase greatly as the already stressed CPU looses a proportion of its clout at that time.
I wouldn’t expect it to impact that much. I did a test with 8 layers of OB-Xd using a brass patch before it started xrunning and it didn’t get beyond 70C.
At some point you’ve got to ask, what the heck is desktop Linux doing to be able to push the 80C temp throttle within 30 minutes… Gnome, Chromium need to get a grip.
My fully enclosed road case Zynth using a Pi4 with heatsinks started to xrun at somewhere around 60C.
I’ve added a case fan to the front panel that blows directly over the heatsinks, and it now runs about 38C. The ambient room was about 19C in both instances. I have a 7" Pi Foundation display. This places the Pi mounted upside-down making a heat trap, so my build was not optimized for cooling.
I direct attached a dumb fan to 5V, next step hopefully this weekend is to add a MOSFET module driven by a GPIO pin PWM, and do some sort of temperature to fan speed mapping. Now welcoming suggestions as to which GPIO I should use…
We’re working on it, but designing and testing a good fanless cooling system has taken longer than expected. Also, we are adding some extra “feature” that would pave the road for new functionality …
Anyway, we hope to release the new kit before summer …
built in MOS Technology 6581 added to the zynscreen
A fully supported ported version of Cubase for the Atari ST from 1989 for touchscreens
A 17th MIDI channel
Wiimote integration as an expression controller
Folding Zynthian
Magnetic pogo pin connector for seamless connection of multiple zynths allowing pianoteq to run at 48KHz with 128 polyphony by connecting 64 zynths with two polyphony.
I’ve been considering the Pi4 as an upgrade to my 3B (non +)
Those who have it, is it a big improvement in performance?
I know some of the Synth presets can be quite demanding and some patches on the OBx and reMID are pretty unplayable. Most Synths do seem fine though.
Its looks like the LAN and USB ports have been swapped, so I’d have to re-cut parts of my case.
Would be interested to hear from those who have upgraded.
