Good value but instructions could be better

The hardware quality is excellent for the price. Installation took a bit longer than expected because the guide was vague, but once installed, it works flawlessly.

Solid construction

The aluminum block feels very sturdy, and the brass nozzle heats up evenly. I've been running PLA and PETG without any heat creep problems.

Works well after tuning

Had to re-level the bed and adjust the E-steps after swapping this in. Once calibrated, prints are great, but beginners might find the transition tricky.

Essential for high-speed printing

If you are pushing your printer speeds, this cooling block is mandatory. It keeps the filament cool right up to the melt zone, preventing jams.

Great replacement part

My original hotend wore out after a year, and this was a cheap and effective replacement. The silicone sock included is a nice touch for temperature stability.

Perfect upgrade for my Ender 3

This kit solved my clogging issues immediately. The cooling is much more efficient than the stock setup, and the print quality improved noticeably on overhangs.

5 FAQ

Q: Are the cooling fans 2-pin or 4-pin connectors?

A: The included fans use standard 2-pin connectors compatible with most Creality motherboard fan ports. Adapters may be needed for 4-pin PWM setups.

Q: How difficult is it to install for someone who has never opened a hotend before?

A: It requires basic mechanical skills and tools like hex keys and a wrench. We recommend watching a tutorial video specific to your printer model before starting to ensure proper alignment.

Q: What is the maximum temperature this can handle for ABS printing?

A: The assembly is rated up to 260°C, which is sufficient for ABS, PLA, PETG, and TPU filaments. Ensure your firmware settings match your filament requirements.

Q: Does this come with a thermistor and heater cartridge?

A: No, this kit includes the cooling block, heat break, nozzle, and fans only. You will need to transfer your existing thermistor and heater cartridge from your old hotend.

Q: Is this compatible with the Ender 3 V2 Neo?

A: Yes, this kit is fully compatible with the Ender 3 V2 Neo as it uses the standard M6 threading and mounting dimensions.
