150mm Aluminum Heatsink 60x150x25mm / 2.36x5.91x0.98 Inch Large Heat Sink Cooling Radiator for CPU MOS Tube Circuit Board PCB Module Cooler Led Amplifier Devices with 24 pcs Fins - Sliver

Well machined (as in flat and smooth) so a .5 mm or thinned thermal pad works fine. Finish vg for the price.

This worked well for my project. I used two of them for some 100W 8 ohm load resistors. In my case, they were mounted in a box with a fan.

Using it to keep an LED driver that is inside a kitchen cabinet cool. Have paired it with a small fan. Driver used to shutdown after about an hour of use and used to be very hot. Now it only get slightly warm and does not shutdown.

Well made heatsink that suits many applications. Easy to drill into and tap holes for screws. The mounting holes works for 4-40 screws, probably also M3 screws.

I used this heat sink to build a small dummy load capable of dissipating 200 Watts. It is big enough to tune the finals of a transmitter and small enough to have it sitting on a desk without getting in the way.

Changed stock thermal pad for my RTX 3090 but it still has 104°C on the memory. Got this heat sink and add thermal pad then it reduced the temp to 96°C!

Fit my project and had 5 spots available to use for screw down. I drilled them out a little larger to tap in a 6-32 machine screw that worked just fine. This is a sold heatsink.

i put it on my gpu, the size an the curves didnt let it do full contact so next time imma two half size ones. even with out full contact it still works great.

I purchased these to use with a DIY Nelson Pass Class A amplifier kit - one per channel obvs. These are a bit of an odd sizing, but work exceptionally well for the standard half-size amplifier chassis out there on the market, in particular, the ones sized appropriately for the lower wattage class A kits. The amount of heat dissipation is very significant and even these modules with a high bias were thermally managed effectively. Very highly recommended. I do suggest running a quick tap through through the hole for the best mounting, but they're otherwise ready to go.

Good quality heatsink easy to cut and mount components. Good value for money.
