Review on 💻 Aluminum Radiator for Electronic Dissipation – 40mm x 40mm x 10mm by Fisseha Rodgers

hot melt pad does not conduct heat well. It's marked 3M but doesn't work like 3M pads. The lettering is also different from what identifies 3M thermal pads. 3M provides the part number and other text - see https://www.amazon.com/8-8x8-8x0-15mm-Thermally-Conductive-Adhesive-heatsink/dp/B07VJ6N6TM. The one already installed only has 3M. The adhesive works well, but the pad is more insulating than heat transfer. The cooler featured a 40 x 40 fan with an airflow of 5.75 ± 10% cfm. Air temperature inside printer case - 29°C Test results after starting a 3D print job for 30 minutes: With original gasket, stepper motor temperature: 70.1°C (hot to the touch VERY WARM) This is a big difference. Engine running at 70 degrees is not what I want. 43.5 C is normal, the fan speed is low and it is quiet. Gasket removal is cumbersome, so buy it without the gasket installed.
