Dynatron K666 60mm 2 Ball CPU Cooler

Pros: This heatsink was primarily designed for server applications. Which makes it design great for those low-profile case users. Heatsink works better than Intel's stock OEM heatsink. Keeps a 3570k cool under 100% load at 70*C. Even thou it was designed for a LGA1156, it will fit a LGA1155 socket too. 4-pin PWM 60mm fan makes it variable control by motherboard controler.

Cons: Heatsink pre-applied thermal paste is not protected when boxed. I found mine with bits of cardboard stuck to it. Expect to clean and re-apply TIM before use. Also the fan has a slight low-noise buzz sound. From a distance or in a well sound proof case this wouldn't be a bother. But the case that I use is a bit thin & airy, so the buzz sound does bother me.

Pros: have 3 of these on a few mini itx builds and they work great. solid copper base helps a lot. you can tell its quality by how much it weighs. FITS 1155 ITS THE SAME AS 1156 would be nice if it said it supported 1155 for searching options.

Cons: loud when full speed and its cooling capabilities are limited... but no duh its a 60mm fan dont expect it to cool a 95W i7 to 30C. but it does well on 65W i7 and 77W i7 ivy bridge.

Pros: Despite quality concerns I can see that it would be a functional product if fixed and applied. I didn't bother. I just RMAed after seeing the issues below.

Cons: Poor quality/poor quality control.
- Loose heatsink fins. They aren't really attached - one came right out and another is loosely fitted over the heat pipes.
- Copper fins are bent to one side.
- Mounting screw was bent 20-30 degrees making installation impossible unless I bent it back.

This thing is just a mess overall for the price they charge.

Other Thoughts: There are plenty of products in the similar price range that don't have any issues like this.

Pros: Keeps it below 60C with no issues. Fits in my cube case and on my gigabyte GA-P55A-UD4P. Easy to install. NO plastic parts which rocks.

Cons: Makes a high pitch whine when under load.

Other Thoughts: If noise doesn't bother you, it's a good cooler for the price.

Pros: Goes in easily, if you know what you are doing. Solid build. Cools well for a small unit. Screws beat push-pins any day.

Cons: Very whiny. My gut told me I should expect it from a 60mm fan, but got it vs. the K985 base on reviews here. Should have listened to my gut! Don't think I have a bad fan, it's just the nature of the beast. Not a bad unit, but where I have it, I can't live with the fan noise.

Other Thoughts: Got a P985 for an older 775 MB and love it. Will replace this with a K985 (same as a P985, but sized for an 1156 CPU.) Need installation instructions for this or the K985, see my review of the P985. Only difference is the brackets. They will only fit one way, metal bar against the CPU Housing. Peel the paper and they have sticky stuff to hold them on.

Pros: Fits in my Cube without touching anything. Mostly simple to install. Runs much cooler than my Intel top to bottom heatsink.

Cons: Slightly noisy but was expecting that from other reviews. On a scale of 1-10 it's a 2 at idle and 4 or 5 when working hard.

Other Thoughts: Like others have said, they should have covered the thermal paste with something... few tiny cardboard slivers.

Pros: Fits the LGA1156 perfectly. Snapped this on a XEON 3430 inside a Supermicro X8SIL-F-O motherboard. Fit no problems. I do like the screw in method which seems to fit tighter.

Cons: none as of yet. I did notice a few specs of dust like the other reviewers mentioned on the thermal paste. Not sure why they could not cover this.

Other Thoughts: Rather expensive for what it is.

Pros: Looks and feels very well made, a solid unit. The included brackets that stick to the back of the mobo make installation a snap, and you can orient the cooler to push air in any direction. The spring loaded screws ensure a tight fit to the surface of the cpu.

Cons: Not exactly a mirror finish on the base, but nothing worth docking an egg over.

Other Thoughts: As noted elsewhere, the thermal compound had little bits of cardboard in it due to somewhat lackluster packaging on Dynatron's part, but if you're buying a third party cooler you're likely buying your own thermal compound as well so in most cases this will be a non-issue.

Pros: + remarkably easy install
+ excellent side-to-side airflow through the heat sink...makes alot more sense than top-down airflow
+ very well constructed, very solid
+ nice price
+ keeps the CPU nice and cool
+ like the option of attaching it to push the air in any direction needed

All in all, a very good cooler and worth the money to replace the stock cooler.

Cons: - "runs quiet" is a very relative term...for me the fan whines a bit when using the PC for "normal" use (also a relative term), not to the point of annoynance or irritation, but it is noticable...which is why I'm knocking off one egg. The whine becomes more noticable when you start doing things that generate heat in the CPU and in the case, like increasing the clock speed of the CPU and/or RAM, for example. Not that you wouldn't expect more noise when the cooler is working harder trying to do its job under hotter conditions, so this is just an fyi, I suppose.
