Pros: None. Can't say much if you can't install it. Dissapointing as all of the reports I have read rated it so high.
Cons: The threaded portion of the supplied mounting screws. are too short to use on my MSI K9A2 Platinum AM2 mother board. Oh well. its just a waste of time and money, of which I can't spare a lot of either.
Summary: I tired to install this on two separate AMD motherboards and both had the same problem.
Pros: Nothing, since it's uninstallable.
Cons: The mounting screws for AMD CPUs are too short to reach and thread into the back-plate. Since it's too short to reach, it's impossible to install! This is particularly upsetting since this is completely a self-imposed design mistake. They could have just make the threads longer.
Summary: For a company that seems to have their designs well thought out, their quality control is severely lacking. When the naked eye can see a problem like warpage, something's definately wrong. This however is NO REFLECTION ON NEWEGG. They've been TOP NOTCH about it.
Pros: Nice design, packed well, very sturdy. The 6 heatpipes should do their job very nicely when combines with Arctic Silver 5
Cons: First thing I noticed was that it was pretty heavy. I looked for ways to rig up a suspension to assist with the weight issue to take pressure off the motherboard. Picked it out of the box to install it, and without even needing a straight edge, I could see the base was warped.
Summary: Like my last heatsink, this only only cools at 0.23C/W, a far cry from the 0.1C/W that Anandtech and other sites got from their review models (no doubt hand selected by Thermalright).
Pros: Still the best design on the market... If Thermalright manufactures yours correctly.
Cons: This is my 2nd heatsink (first had an issue w/ the heatpipes). This one's base is warped. On one side the image reflected in it bows outward, which indicates it is convex. However, It is not by design because the raised point is not in the middle of the heatsink where it would improve contact pre...
Summary: After numerous tests at different speeds and voltages, my Ultra 120 eXtreme is running at about 0.23C/W. This is far far worse than the 0.1C/W that working models show. I know it's not my rig because the stock heatsink still manages around 0.35C/W, which is very close to the performance it is...
Pros: Best heatsink -design- on the market. In theory provides the best cooling available short of dual 120mm radiator water cooling setups (and you'd need a good pump and block too).
Cons: Quality control is awful. Other people have had issues with their bases. My base wasn't terrible, but it still cools nowhere near what it should. Best guess is the heat pipes are defective. For heat pipes to function they need a small amount of fluid in them. If the fluid is the wrong mixture (ne...
Summary: I shipped a $2500 computer with a back up after this disastor of #$%%. The mounting system does not allow the heat sink to be compressed flat on the chip. I spent many hours studying and testing this heat sink.
Pros: Probably the best heat sink made if you modify the mounting system - but with the poorly engineered mounting system its 10 c hotter then the butterfly one. I truly think this is the best heat sink available today as far as its potential and ability to cool. Unfortunately it does not even get hot....
Cons: Does not fit flush do to poorly engineered mounting system. This heat sink cost me alot of money in time and a sub par computer. I love thermalright but this ... as cost me so much!
