Pros: small and gets good signal (when it's working)

Cons: After a day of use it starts to get disconnected randomly. I tried multiple USB ports and the same issue happened. Not reliable.

Pros: Good build quality... Looks good too

Cons: A bit heavy. Poor documentation as to how to use this in cases where you want to expand storage (non-raid). See below for further details.

Overall Review: I have a Asus Z87 gryphon motherboard with a moded bios. I can run NVME drives bootable and everything works fine. I got this card simply to expand storage, i.e. to use 2 NVME drives (one bootable and one for storage). The Z87 chipset supports pcie bifurcation, so in theory it should work. But sadly only the first m.2 slot gets detected. I tried fiddling with the bios (csm compatibility...etc) to no avail.

Pros: Best bang for the buck in terms of raw power. You just can't beat it at 250$. Overall very pleased even with the included cons.

Cons: 1- Fan becomes very whiny at above 70% fan speed. 2- There is a common issue with R9 290s in general. For some reason some of these cards reboot your PC randomly. After a lot of digging around in forums the problem was traced to the base 2D core clock. Basically when the computer is idling or under low load the GPU decreases the core clock to an extent that causes the PC to reboot for some strange reason. Remedy: use Asus GPU tweak to increase 2D clocks to 430MHz. This completely solves the issue. For further details look up "R9 290 random reboot".

Pros: Awesome product. Definitely helps with cooling mosfets. This thing allowed me to push a fx6300 to 4.2GHz on a cheap mobo. Comes with 5 extra thermal tapes.

Cons: None

Pros: Good size, will fit most cases. Runs very cool. Definitely good for overclocking.

Cons: none.

Pros: Cheap and looks good. Good selection of LED colors.

Cons: Mediocre air flow but the biggest con is the noise. These things are very whiny (I got 2 of them). Changing aux fan speeds from bios did not change the fan speed, it kept running at 1900rpm. I ended up removing them and using the 80mm fans that came with the case. Not recommended.
