10pcs Aluminum Heatsink Cooler Circuit Board Cooling Fin for Raspberry Pi,VGA RAM,IC Chips,Mosfet SCR, with Thermally Conductive Heat Transfer Pads

I would give this 5 stars had the thermal tape come preattached. As it is, the squares aren't all evenly cut, and since the heatsinks are so small, it's hard to line them up without overlap and then you can also get bubbles that you only hope will smooth out and not have air pockets in it when you put them in place.I picked up some 20mm heatsinks from another brand, and those came preattached. You can see the difference in looking at it, with these ones having bits hanging over one side because it's next to impossible to line them up properly.Otherwise, they do warm up nicely, so are pulling heat away from my backplate, and the tape, so far at least, is sticky enough and stays sticky through the crazy heat my GPU throws out.

They are exactly as advertised so if you need small heatsinks and adhesive thermal interface material, these are perfect. I'm using them to tool some easydriver stepper motor drivers. however I could see them working well on a Raspberry Pi or VGA Ram as stated in the description.Do take note of the dimensions, for some reason I thought these were 10mm when I ordered them (I did not really check) but was pleasantly surprised to find 14mm. totally fine for my use case but on the off chance your like me and just saw a picture and made an assumption...

Helped keep it's temp down with passive cooling. stuck 4 on it and went from to hot to touch to barely warm. thermal pads seem to work well and seem to have quite a good adhesive on them, time will tell how it's thermal stability is.

Ordered these for a small all-metal HDMI capture device I have that gets really hot when in use. I stream on Youtube and Twitch and so does my roommate. His same model capture device burned out due to overheating so I had to do something. These work to keep the device passively cooled. They're originally intended for the Raspberry Pi but they work just fine. I lined them all up on one side of the device, the side that gets the hottest and I've noticed the capture device is a bit more stable. I'm thinking of ordering some more for my Chromecast which also gets blisteringly hot.My package arrived minus the thermal adhesive pads by mistake but I contacted the seller and they corrected the program really fast.

I use these on a metal ruler to help dissipate the extra heat from laptops when I am overloading the video card and the ambient temp is high.

They arrived in a timely manner, as pictured. They are the perfect size for cooling individual VRAM chips on my custom RX-480, and the black color is a nice aesthetic. HOWEVER, do not use the included thermal pads! They appear to be off-brand, and not manufactured by 3M. Furthermore, they are not adhesive at all; as soon as I applied them to the VRAM they fell off with hardly any force. No matter what I tried, they would not stick. Will be buying Arctic Silver thermal adhesive to glue these so they don't fall off in my case.

There is not much to say, except perhaps that almost all makers of aluminum alloy heat sinks insist in anodizing their product despite the fact that aluminum oxide is a very effective thermal barrier, despite the extreme thinnest of the oxidized surface layer, and this reduces the effectiveness of the heat sink quite significantly.This product would be better (more effective at dissipating heat, and cheaper to manufacture) if left as bare aluminum.

Meh, these heatsinks are so-so. Since they are aluminum and don't conduct as well as copper, you may have issues if you are dissipating a lot of therms. I am also skeptical about the peel-and-eat thermal adhesive (which is not the old-fashioned gooey variety that conducts heat wonderfully.) I have them on the processors of a pair of 1 TB m2.SSD modules on my NAS' tiered storage and one of the modules is frequently crossing the 70°C mark under moderate load. The sinks are directly in the forced airflow and should get plenty of cooling, so the only thing to do is double down on the sinks by sticking a second one on the memory core to see if that helps with the overheating. If that doesn't help, I guess I will be very carefully yoinking the sinks off the modules and replacing them with copper.
