Summary: This fan was a exact match for the existing fan on my Cooler Master TX-3...I just popped it into place, ran a PWM splitter to the fan control header on my motherboard...and my APU is nice and cool.
Summary: Purchased this to replace a dead fan in an hp pavilion. Amazed that this fan was so much quieter than the one the box came with. I even had to take the side off to look at it and see that it was working because it was so quiet!
Summary: I have a Cooler Master TX3 heatsink, which comes with one 92mm 4 pin fan. I recently upgraded to a motherboard with 2 cpu fan ports and I needed a second heatsink fan to match for a push/pull setup. This fan was a perfect choice! It is the exact one that came with my heatsink.
