5PCS Creality 3D Printer NTC Thermistor 100K, NTC 3950 100K ohm Thermistor Temp Sensor for Creality Ender 3/Ender 3 Pro/Ender 3 Neo/Voxelab Aquila, XH2.54-2P Connector (1m/39.4inch)

I was having trouble with runaways until I bought these for my 3D printer. Problem solved, and Ive got several backups just in case!

I purchased this product when the stock thermistor started having issues. I would only be able to print for several minutes before the printer would scream out an error at me (Ender 3). Replaced this one fairly easily, but you might want to watch some YouTube videos prior to installing it yourself.

Being new to 3D printers, I have no clue as to what is normal when it comes to parts. Not wanting to take chances on getting the wrong ones, I purchased these because the description specifically states it will work on the Ender 3 Neo and they’re from the same company as supplied the Ender printer I bought at Christmas. I even spent the extra $2.99 to get extra fast delivery. Alas, I found all 5 of the thermistors had glass bulbs which were .3mm larger than the one my Neo came with (1.91mm vs. 1.61mm) and wouldn’t fit into the hole the old one came out of, rendering them useless… or so I thought. I came across another review from someone with the same issue who said they resolved the problem by drilling the hole slightly larger. Finding I could get other thermistors built into a 3mm threaded bushing (going in the old screw hole), I figured I had nothing to lose by trying to drill the hole a little larger. TL;DR: a 5/64 drill bit is the perfect size (pretty much just cleaned out the hole) and I was able to position the print head in such a way that I was able to drill it out without taking everything apart. The thermistors fit perfectly now and I’m an hour into my print job; temperatures are holding steady. With any luck, it will last longer than the two months, the first one did before acting up. EDIT: I changed my rating from 3 to 5 stars. After more research, I determined the thermistors I received are probably a better quality (sized properly and not a distorted shape) than the one that was originally put in - and it was likely a thermal paste used on the old smaller one which was keeping the new ones from going in the hole. I did not install the new one with any paste and so far it’s working great; opinions differ on whether to use it or not. ALSO, Comgrow reached out after my initial review and offered a full refund which was a nice touch but refused. Perhaps, if I had reached out to them first, they would have suggested cleaning out the hole. A good learning experience nonetheless. I hope my experience helps someone else.

Thermisters worked perfectly and are of good quality. Very pleased with my purchase and its nice to have spares for when I need to replace them. Very good buy.

Great direct fit replacement. The wire was stiff enough to fish up the through the tube netting without bunching up.

They have worked perfectly, it went well for the cost and I liked the organization as they came to me, it was quickly to assemble and start printing.

Good direct replacement for creality and ender printers

Not good for ender 3 max to short

I bought these a while ago when I was having trouble with my prints and I made the classic mistake of making several changes to my printer all at once. I replaced heater cartridge, thermistor, and hotend all at once (I had accidentally engulfed all 3 in a giant blob of plastic that I didnt want the headache of dealing with). Historically, I had been printing with a brand of PLA at 210 C, but after I made the switch, I found I was getting pretty bad results with 210, and dialed it back to 190. I chalked it up to the fact that I had replaced the hotend with a new all-metal hotend and adjusted accordingly. But I recently learned that you would expect to _increase_ an all-metal hotends temperature, not decrease it. Ive been printing some temperature towers, and I seem to be able to print PLA at temperatures colder than it should melt at. Ive gone back and measured the resistance of these thermistors at room temperature, and theyre reading about 150 kOhms instead of the 100 +/- 5 kOhms theyre supposed to be. So I guess Im just happy that these thermistors didnt accidentally start a fire :/

Works great on my Elegoo Neptune 3
