## Customer Reviews

### ⭐⭐⭐⭐⭐ These seem to be working good
*by J***N on July 19, 2020*

I have used these to mount new LED chips. The chips are 50 W and they do not require a driver to convert 120 VAC to DC. The chips are 40 x 60mm and the heat sinks are 40 x 40, so there is an overhang of about 10mm on each side. I tapped the heatsinks with a 6-32 tap and put Artic Silver heat compound on the surfaces before mounting solidly with four 6-32 screws.I have used a laser heat measure to measure the heat right in the center of these heat sinks. I measured 212 degrees F after the LED had been on for one continuous hour. The LED themselves have a thin aluminum back. When I measure the heat on the back edge overhang of the aluminum LED it only measures 100 deg F. So it appears the heat sink is drawing the majority of the heat right into the heat sink. Measuring the temperature anywhere on the face of the LED I do not get any temperatures over 100 degrees.I should add I did this in July and my garage is just that (a garage with two cars parked in it), with no AC. It was around 85 to 90 degrees inside the garage. So far, I am happy with these heat sinks.

### ⭐⭐⭐⭐⭐ great quality heatsinks
*by J***B on July 31, 2021*

product arrived well packaged. condition was satisfactory, have not installed them in my gpu yet, I need to cut them down to size. will update the review if I see the heat shedding is low.

### ⭐⭐⭐ Not copper
*by H***Y on February 6, 2025*

...copper colored, but not copper. Still a decent deal for 20 aluminum heat sinks that works great on a nema 17.
