Easycargo 100pcs Heatsink Assortment Kit Small Cooler Aluminum Heatsink Set for Cooling PC Laptop PS5 M.2 CPU GPU VGA RAM VRAM VRM IC LED MOSFET Transistor Voltage Regulator (Preapplied Thermal Tape)

I purchased this because the TP4056 module (I also purchased along with this) is known to get too hot if you supply to it more than about 750ma. I stuck on a 9x9x6 with my heat sink tape and temp dropped 10c. Went from 56c to 46c. Now the chip on the TP4056 can handle up to 80c, but why stress it when you can slap on a tiny heatsink that cost a couple of pennies?

Nice compact kit, good selection of sizes but please understand what this is targeted at. These are for low heat output items, the largest size is 22x22 which is less than a square inch. .. it would have been nice if they had included a few more around that size.. (kit only comes with 2) you would put this on small chips, I'll primarily be putting them on consumer market router SoC's and wifi chips. Raspberry pi's would be a good candidate also, you could cool things like small Mosfets, VRMS, Ram, surface mount inductor coils, things like that. You could probably get these cheaper individually but you'd have to buy more of each size, But this is actually a pretty good value for the selection if you need a 1 and done kit and the case makes it easy to keep organized. These have no mounting hardware, you will need either thermal adhesive tape (don't just use double sided tape), or thermal glue (I recommend tape as it's easier to remove later if needed) Get the kit that has tape/glue included if you don't already have, or buy it separately. I bought the no-tape/glue kit cause I already have tape.

These heatsinks work well and come in a convenient storage box which is organized and has labels. They are basic aluminum heatsinks and don't come with any thermal adhesive or thermal pads so make sure to pick up some thermal interface material. Honestly, there really isn't much to say, they work well, are affordable, and come in multiple sizes. I would recommend these wholeheartedly and will buy them again when they run out/I need more.

After spending money here and there to get individual heatsink kits for my ever-growing Raspberry Pi and similar SBC collection (which have always come with adhesive tape pre-attached), I decide to purchase a bulk kit to always have some on hand. I should have paid closer attention as these arrived without adhesive so now I have to order and wait for some thermal glue to make use of them. If you already have some thermal tape, glue, or paste, this kit is perfect. Otherwise, look around and you can find some heatsink kits with pre-affixed adhesive for close to the same cost as this and a tube of thermal glue or roll of thermal tape. That all said, the quality of most of these heatsinks is pretty nice, particularly the black anodized ones. The smaller plain aluminum ones are pretty standard fare but there's far fewer of those than the anodized ones.

Nice collection of heat sinks for a reasonable price. Use these on a Vega 56 video card that guy converted to water cooling. Use these on the VR a.m. and they have maintained their position with the tape that I used and purchased as a separate product. I’m not sure if heat sinks are particularly effective in reducing VRAM heat, but they’ve stayed in place and the VRAM hasn’t gotten excessively hot.

Well made!

What do I mean by living on the edge. If you whipped up a circuit that requires the absolute maximum rating of, lets say a voltage regulator. You might get away with it by adding a heat-sink to the component. Electronics components have usually a maximum rating, if you can keep them @ 25C. The various sizes are excellent and there is likely a size you need. The temperature will probably go beyond 25C, but it will extend the operating range. The bad, you'll have to get some type of thermal glue, otherwise there is no way to attach the heatsink without a major mechanical gizmo. However this is to be expected.

These work great with adhesive thermal compound and can change the temperature from "unable to touch" hot to barely warm in ambient air, When it runs hot it just breaks sooner, this can add years to the life of your circuitry.
