I read something awhile back about Eric suggesting ordering the silicone heater with a hole in it so the thermistor can be replaced. Any ideas how big the hole should be? My idea was 15-20mm, but I’m not sure if that’ll leave enough surface area for the thermistor to stay adhered to the heat spreader
I leave a 25x25mm hole in all my heaters, drill a small divot in the spreader, and place the thermistor in some thermal paste (very small amount). Then secure it to the heat spreader with some polyimide tape
Very helpful, thank you! I neglected to ask if it would be a good idea to go ahead and order a spare as well. Have they been fairly reliable in your experience?
Mine from alirubber have been running well for years. Same with people I know who bought keenovo brand. I think if it is properly spec’d, wires are strain relieved, etc… That you should see a good service life.
Cool, thank you.
So, for whatever reason, alirubber hasn’t responded to my inquiries so I turned to Ebay. The seller, jsr2industries, was very responsive and I was able to order a 380mm x 380mm heater with a 25mm hole for $65.80, shipped. I expect to have it middle of August. I’ll let everyone know how it turns out!
