What is your laser power and what are your water temps. And what is getting too hot. I have had different answers else where.

40W water between 15 and 20 C

I try to keep mine right around 65f/18c never let it get over 72f/22c I would think that anything over 75f/23c you would start to loose cutting power.

18 or 19 c for both machines

80w ~ 18.5-20c

In the winter I've run as low as 13.5, no problems. This summer my swamp cooler blew it's motor, and for a few days my garage shop was without any AC. I had temps hovering near 30 at times. I won't do cutting when it's that warm, but I'm not afraid to run Rowmark at 14% power for 20 minutes.

My average temp runs 24-25, simply because that's the room temp. I'm sure that's above the limit for many. I don't have a reefer cooler. I haven't done any 'extensive' testing to see if there's any noticeable power differences in temp differences, but in normal use, I haven't had to up my power settings because the water's warm...

I'm the tropics and (for the time being) without air con, so I try to keep mine below 23C (73F). Makes the chiller work a bit.

Of my watercooled units

180 watt 17-18C
200 watt 17-18c
230 watt 17-18c

air cooled and industrial vary by a bit more depending what power they are running at

Must be nice to be able to run it that cold. I'm sitting at 22-24*C. If I go any colder the tube sweats really badly.

Factory temp and humidity is controlled, 22 -24 C all year round so keeping the lower tube temps isn't too hard

I keep mine at 18c. I would keep it colder if not for condensation. I'm using an aquarium chiller and an Igloo 5 gallon drink cooler.

130W 19C generally. Sometimes up to 21C.

I am also in the tropics and run my 100W on a 5200 chiller that maintains 19-21C. My 60W runs on a 80 liter bucket of ambient temp. water - normally about 24-26C. But I found that in our summer (ambient 30-32C) I would lose considerable power when the cooling water got over about 27-28C. Chucking a few re-freezable chiller blocks in would usually cool it down enough to finish most of my jobs.
Love the new chiller though!

60W @ 14.9 degrees steady (but my workshop-temperature is only 16-17 degrees average)

I got condensation on my tube all the time because of the ambient temp of around 36 C and like I said my water temperature runs between 15 and 20 C. my cheap tube ( ebay $ 160) last around 1,300 hours.

80 watt tube. Temp hangs around 18.

Well the question is.......... Is Condensation bad for the laser tube.

Havent seen any so far. But humidity is normally low here, at least until winter rains/mist pick up in earnest.
