Pros: Ice Cold to the touch. This thing is a beast.

Cons: It was too big for my case. I had to dremmel the case wall to make room for the poky bits and the end of the cooler. Then when I got a new motherboard it slightly shifted the cooler so I had to dremmel holes again.

Other Thoughts: You can completely remove the fan! I had left mine on for a year and the inside (between the fan and the metal fins) became so completely caked with dust that the fan was ineffective anyway. So I removed the fan and just stuck it in my computer anyway. It works great! Just the airflow in the case itself is more than enough to cool my cpu. If you want a silent computer this heatsink is a great start.

Pros: The performance for the price is great. Keeps my 15 760 @ 3.5 at the low 60 degree range during prime 95. It is not ridiculously huge either.

Cons: Installation is not idiot-proof, as I learned the hard way. I damaged the push pins during installation and it would not seat properly. My 760 was reaching 99 degrees at stock. Do yourself a favor and get the screw in mounting kit. Spend the 9 bucks now. It made all the difference for my build.

Pros: Not quite as awesome as some people made it out to be, but it cools my Phenom II X4 940 pretty good. Gave me enough head room to get up to 3.4Ghz and max load temps only hit 51C. Was getting max load of 53C with my old Zalman 9500LED, but it didn't have what it took for this processor. The Xigmatech gives me idle temps around 39-40C at 3.4Ghz, so not bad, but before overclocking, it was only about 2-3C cooler at idle.

Cons: Quite big, and for AMD users you pretty much MUST get the crossbow bracket for an extra $10 to mount east/west so that it exhausts out of the back of the case. I am not one who cares about noise, so I would actually prefer a fan with higher CFM than the one provided.

Other Thoughts: Overall a good cooler, just disappointing to have to pay extra for mounting hardware that should be included. $10 for a couple pieces of plastic and some screws is not cost effective.

Pros: Working well. Keeps a 1090T running at 3.6GHz at 50C loaded with Prime95.

Cons: Fan is only 1300rpm at max, could be a little faster and still be quieter than other noise sources in the case when under heavy load

Pros: Cheap $15 When I bought it
Quiet
Q6600 nice and cool
Light Weight
With Bracket = Solid as a rock no worries of push pin popping out.

Cons: Wasn't able to hit 3.4ghz....hot running chip sadly but that doesn't effect the cooler! Sadly spending $60-70 for a better cooler just doesn't seem worth 200mhz.

Other Thoughts: Q6600 @ 3.2ghz 1.35v 34-36-34-31 idle and 55-55-50-50 load (85F room) fan is set to auto so many I could have it lower.
There might be better coolers out there but if your reading this then your not one of those people who overclock to the extremes.

They claim the fan dBa is 20 - 32 but at max speeds I don't hear but a whisper...yet a similar 24 dBa fan I bought from Scythe is like a jet engine at similar specs (rpm/size etc)

If anyone cares to explain this to me I will check in on the reviews.

Pros: Cheap. For the amount of material and the quality of the heatsink, it is a highly cost-effective product.

Cons: The included thermal grease--as with most heat sinks that are not made by Zalman--is nothing to write home about. Even with poor thermal grease and the fan attached to the back of the chassis, the cpu idles at 36 degrees. Not too bad.

Pros: Keeps my unlocked Athlon 440 very cool (25* idle, 32* load in 20* room temp).

Fits in my Antec 300

Very sturdy construction, doesn't feel flimsy.

Cons: The no-vibration rubber mounting things are annoying to work with, metal clamps are easier, but I guess are also inferior otherwise,

Pros: well designed cooler

Cons: missing the plate specified in the directions as "AMD plate". Unable to use with the AM2/AM3. :(

Pros: Cheap and reliable Heat Sink and fan. Great cooling performance for it's cheap cost.

Works well with AMD FX60 oc'ed to 3ghz

Keeps temperatures below 50's idle and ~55 Load on my AMD PII940.

Cons: Could use a fan with a higher Static pressure. (ie. so the air doesn't go over the top but though the tightly packed fins)

AMD setup forces fan to be Pushing/pulling air to the Power Supply. instead of towards the Exhaust fan

Other Thoughts: For the price. this is a GREAT cooler to get.

I've used this with Artic Silver MX.

Pros: Great cooler - cpu doesn't get above 50c even under load. That's pretty good for 6000' where I live. Once you get right mounting hardware, straightforward install.

Cons: This WILL NOT MOUNT on a 1366 motherboard WITHOUT THE MOUNTING KIT. Consider that extra $10 in your calculations and don't wind up waiting another week to receive the kit after you figure this out the hard way.

Other Thoughts: why the heck don't they include the extra mounting hardware? Sheesh.
