How hot is too hot?

Looks like I'm running about 42C. I have the small fans attached and a larger fan blowing on them.
Topic: New GekkoScience product, the Compac A1 (Read 1476 times)
Shout out to the peeps at GekkoScience! Super quick shipping and quality products. Loving my 2 Compac A1s and USB Hub! Now to start tweaking settings!
Thanks!
Do you guys have a website I can purchase from directly? Thanks!

I'm running the 4.13.1 build from kano under windows 11, installed the compac a1 zadig driver and I can see the module when I issue a -n switch, but cgminer cannot see the ASIC. I am running a capable USB hub which supports up to 3A on which I am also running a 2pac bm1384 and a compacF 1397 without issues. Does anybody have Any ideas ?
What is a safe frequency to run these Compact A1s? What temps are safe? I have a smart hub and use the gekkoscience API.
Hello - Does anyone know where I can get the onboard plugin fans for the A1?
thanks!
thanks!
The only limitation is one of cost; the cost of adding a USB-C PD power supply to the design.
With standard USB, the power supply is pretty simple the host just provides 5V at up to 900mA(USB3.0 Type-A spec. Hubs tend to provide more power up to 2.5A) into a DC-DC converter to derive the core power supply for the ASIC.
However USB-C PD requires a more complex controller additional board space and the associated costs with it and a more expensive DC-DC converter solution that can operate at the higher input voltages from USB-C.
Data is on a separate set of wires, so you dont even need to draw power from the bus in self-powered devices and it is always available.
Otherwise I cant see anything that would prevent you from doing it.
When you are talking about the cost of stick miners like this in general, is all the additional cost of the parts going to matter?
I can see the added labor time of the design and testing but could it really be more then a few dollars more in parts?
Could be wrong, but when Canaan can get an Avalon Nano 3 out the door for under $100 then I can't see it driving up the price of a stick miner that much.
Just a thought.

You're right, but you're viewing the product development from the perspective of a user.
If you look at it from the perspecive of a small manufacturer, $5 on the BOM cost is many thousands of $ off your ROI if you're targeting a fixed MSRP and limited market size.

USB-C by itself defaults to 5v 2a (10w). Any higher requires USB-C PD which is now at v3.1 and will output higher voltages (up to 48v) and current (5A) for up to 240w when attached to the appropriate devices with the correct cables.
Which is kind of my point. You can get enough power out of the ports to do this. Are there any limitations as to why it can't be done?
According to the 1st post "260GH from under 8 watts" Even allowing for 20% overhead that's only 9.6 watts. Bumping to the 10W max but still under.
PD can go even more, just don't know if you can move data or do other things at the same time.
Probably not the most useful thing, but any reason it can't be done?

So I was thinking (always dangerous) could something like this be powered with USB C
I know my PC puts out enough power to charge my laptop, is there a reason it would not be able to run a stick at decent speeds?

Hello - Anyone know how to get this stick to work on the GekkoScience Hub??
Thanks!
Thanks!
hey, have you sorted this?

Should be possible but the speed's gonna suck, likely under 100GH.
Running w/o a hub I doubt. A PC USB port will not be able to deliver enough current, most have a limit or 1A or less.
Possible to under clock enough to run without a usb hub or fan?
Quick question, currently running the older version of kano's cgminer, launching with a batch file with these settings --gekko-compacf-freq 575 --gekko-mine2 --gekko-start-freq 300 --gekko-tune-up 60 --suggest-diff 442 --gekko-compacf-detect --
I'm running the Compaq F's right now, just curious if I pick up some of these new A1's and run the new cgminer, can I just add to this same batch file any necessary settings? If so, what would be the mandatory settings?
