Pros: This thing keeps my i5 2500k at about 31 degrees under normal load, and 38 degrees playing Battlefield 3 on High. The CPU temp registers consistantly lower than the motherboard temp. It isn't too big. Installation was pretty easy.

Cons: The design is a fan between two circular copper heatsinks. During the installation I guess I pushed the two heatsinks closer together, which blocked the fan, leading to a CPU fan fail warning from my MOBO. I checked the connection to the MOBO and tried again with same result... then noticed that fan actually wasn't spinning at all. I was a little upset and thought I'd have to RMA the heatsink, but then noticed it was just the heatsink blocking the fan. Not taking off an egg because I was thrilled once I pulled the heatsinks off the fan a bit, it worked great (was worried maybe the motor killed itself trying to push the fan blades while blocked). Nope! I would only like to see some type of stabilizer between the two heatsinks so you couldn't squeeze them into the fan.

Overall Review: I'd buy this brand again.

Pros: Worked great/fast for a little over two years.

Cons: Purchased in late 2011. A little over two years later (normal use), windows started randomly crashing (BSOD) and on reboot, the computer would say no physical disk found. Further reboots would then work as expected. Worried that the hard drive had problems, I ordered a new SSD and used Clonezilla to clone the bad SSD to the new one. At 98% complete, clone failed and Clonezilla alerted that the source disk had bad sectors. Tried again and clone worked. Just glad to be rid of this drive.

Overall Review: I gave it two stars because it worked fine for a bit and at least died gracefully enough I had time to plan for it... though only worked for two years, so I wouldn't recommend this SSD.
