Pros: cools better than the fan/heatsink that had died. Copper. Solid. Clean. Comes with aluminium RAM heatsinks. I put one on my Raspberry Pi SoC. The rest went in the trash.
Cons: Seriously? the lights. What is the point of putting a little blue and red light on this? Even just one or the other wouldn't make it look like a police car. Save the few cents that the lights cost and make the fan of a little higher quality. Not really good for video card setups. The mount holes match many northbridges, but no modern video cards have holes at this distance. Knowing this, and intending it for use on an AMD HD3400, I also purchased some arctic silver th...
Pros: Works great as a northbridge or southbridge replacement cooler, or for small HTPC cards. The setup is the circumference of the top of a pop can. I'm glad it came with thermal paste and 8 copper heatsinks I can stick to things.
Summary: Originally used it in an older computer which didn't have the correct wire ends. I soldered in the plug from the old fan and plugged it back into the card. This is, of course, not what the manufacturer would recommend.
Pros: I installed it on a FireGL V3100. I don't have a way to measure temps right now but with all of that copper mass it has to be cooling better than my stock fan did. Installed onto the card easily except for the wiring.
Cons: It is a little bit too loud but I'm not sure a 45mm fan could be much quieter though.
Summary: Fits many amd/nvidia gfx cards including my GeForce 5700LE. The fan may draw more amperage than the stock gpu fan. So if you're on the edge of your psu's capacity you may see some random weirdness. Hardest part was trying to pop off the old heatsink/fan without damaging the pcb. Next time I'll look for a video tutorial before breaking out the sharp-edged objects.
Pros: Solid, very hefty chunk of metal to pop on the gpu. 8 small heatsinks with self-adhesive for the gfx card memory modules. Includes a heat transfer compound so you don't need to buy that separately.
