Review: Seem to be solid and will do the job. - Seem to be solid and will do the job. Time will tell how well they hold up in actual use but working for now.
Review: Works fine! - Haven’t had any leaks. I took an x-ray because i wanted to drill and tap two holes to mount a couple of MOSFETs and I didn’t wanna accidentally drill into one of the coolant channels. It turned out the coolant channels inside the block were too narrow for screw size I wanted to use. I used super sticky thermocouple tape instead. I could probably still drill, and when I hit the cooling channel I could immediately stop drilling, tap the hole, and use a very short screw so that the screw doesn’t block the cooling channel, then add some locktite or rtv to the threads, but I did the lazy thing and used the thermal tape, lol

### ⭐⭐⭐⭐ Good heatsink for the money.
*by M***P on October 21, 2021*

Great little heat sink for the money barbs hold a 5/16 hose without clamps and does not leak. Only down side is the surface finish was not the best had to make the true and polish out the roughness but I have something that a nearly smooth finish is needed. This shouldnt be a problem for your average user.
