Pros: Good price, the stick very well.

Cons: Cost more than the taller ones??

Overall Review: I used one of the on the back of my upper most 5770, because one of the taller Enzotech sinks was hitting my Noctua D14's fan clip. To the guy with the 5770, the problem with the ram on the 5770 is that the ram on the GPU side has a cheap aluminium heat spreader that gets no air flow. I installed ram sinks on both sides and I got about 200MHz more memory over-clocking out of it.

Pros: Cheap, would work in a low end system

Cons: Voltages are poor every rail is at least .02 off and is very erratic. Ive measured about a .01 voltage difference while running stock clock on a 4800+.

Pros: A really good value. Less than one half of the quad core version. AMD's epic backwards compatibility allows me to use it with my AM2+ board with DDR2 ram, and allows me top upgrade to AM3 mobo with only replacing the ram. Really cool compared to the quad core. A lot of over clocking head room with the stock heat sink.

Cons: AMD should start giving real thermal paste for the Black Edition CPU's or a different heatsink.

Overall Review: Do you self a favor, get some ArctiClean to take the stock thermal interface compound off and some Arctic Silver 5 to replace it.

Pros: Work at DRR 800 CAS 5 at 1.8V. Cool.

Cons: The thermal pads that hold the heat sinks on are loose. Not bad unless you don't handle them correctly. You should really never handle the ram by grabbing the faces. You should hold it by the top corners. You should NEVER pull ram by the faces or heat sinks.

Overall Review: I removed the stock thermal pads and used some diamond paste with a bit of Arctic Alumina to hold the heat sinks on.

Pros: Fast, Works. A ton cheaper than a SSD for GB/$ and (MB/s)/$

Cons: I have 1 in my MythTV box and it is the loudest thing in there because it is fanless. I have another 4 in my desktop in RAID5. When I do a lot of random read they make a bit of noise. Not loud enough to take an egg off as they are meant for speed. Get WD greens for things that need to be cool/quiet.

Overall Review: Also you have to have forced air over these things. One got up to around 60*C in my MythTV box until I installed the front fan for the case.

Pros: Cheap, quiet, works, and fits.

Cons: Not free. Must supply your own beer for installation as none is induced.

Overall Review: At this price there is nothing to complain about if it works. It burns DVDs and it's SATA so the cables are smaller.
