75F is a lot lower than I expected. I wanted to put it in my garage, but even my house air conditioner is only set down to ~77F during the summer.

I think it may be too early to assume this is the final answer. The complete quote from dan was:
It’s the ‘One we get Pro units in more hands’ part that I think is pertinent. At this point they still don’t have a lot of pro units up and running, and certainly not in the hottest part of summer where the issue with basics was so pronounced. As with the basic currently, they just might end up letting it run hotter than what the manual says.
One of the advantages of a peltier device is that you can probably switch the one in the GF out for a more powerful one. But that would also require a dedicated power supply since these things take a lot of amps. I think that post-warranty I’m just going to replace it with a copper block that has chilled water running through it. The location of the peltier makes it convenient to run some copper tubing out the back to hook the water chiller up to.

If you’re talking about the makerspace at Google’s Mountain View office, then that very same laser is the first one I ever used. It’s where I prototyped the Robot Turtles 3D edition.

Cool! The one I was referring to was actually the NYC office, but I have been to The Garage in my meanderings.

My understanding from other discussions is that the operating temp of the coolant is higher than 75F. The rate of passive heat dissipation via a heat sync is a function of the difference in temperature between the coolant and the air. If the operating temp is 90F* then they seem to be saying they need at least a 15F differential to dissipate the waste heat from the laser.
If you only have 10F differential, you can still run the laser, but the temperature would tend to rise to 95F or so before reaching equilibrium. Therefore, it would need to pause when the temp exceeds 90 and wait for it to cool to something lower before restarting.
*90F is a temp suggested in this post: Non-Pro Performance in warmer climates - #21 by PFI-Guy

IMHO good to see that @dan is across this thread, but disappointing that the only contribution to the conversation was about a Maker Space!
Some important issues are being raised here about GF operating environment and it would be good to have some official comments / reassurance…

they’re not going to comment on anything like that in the beyond the manual section, i don’t think.
I just changed the title because it’s not really “bad” per say. I mean, I ran a continuous score for 45 minutes in an 84°F room without the machine pausing due to heat.
Yes, people were hoping for more but considering this unit comes self contained and is completely plug and play I’m not sure this is a huge disappointment.
And as discussed in this thread, Heat Issues? Basic and Pro comparison?
It seems as though modification of the cooling is possible.
Unless my wife forces a move to the garage it’s certainly not an issue for me. Even then it would be a period of about 3 months out of the year where it may present an issue.r

Never seen an over temp warning. But we’re pushing that time of year in the WV mountains where I will be able to check if there is a new under temp setting. Operated for months early this year 10F to 15F below their minimum stated temp.

In my experience that’s the limit, I have wait to get around 78F to get going and sometimes after a long job I still hit the “cooling” message.
Oz = KS or Oz = Australia? …from one Oz…

Australia.
As the Emerald City was Washington DC, would that make Oz = Northern Virginia???
