Excellent Cooler
- Pros: Rock-solid mount using back-of-board mount. Positive screw mounts secure HS to processor. Lots of surface area. Not so tall that you cannot mount intake fan on case side over the top of the cooler.
- Cons: Need extra $10 mounting kit for 1156 and 1366 coolers. Fan itself and mounting clips extend enough to side to make contact with tall heat-sinked memory sticks. Without simple modification to fan clips, tall memory sticks severely limit directions fan can be oriented.
Fan unattractive color.
- Other Thoughts: The usual way fan clips connect to fan is to have bent "elbow" in wire fit into fan corner mounting holes. This will cause wire to protrude several mm out from the side of the cooler, possibly making contact with tall memory sticks.
By simply rotating this elbow 90-degrees with a pair of pliers, the elbow turns into a hook that will grab onto the mounting post and pull the wire flush with the side of the cooler.
Works well
- Pros: Made to fit in situations that you cannot use a taller / larger cooler. Dropped 9c off of idle and 8-10c off of load depending on ambient. You do not have to remove your mb if you use a AM3 board that already has a back plate, just unscrew your retaining clips and place the thin clear washers over the stand offs and assemble per directions. You can even use your orginal retaining clip screws. Nice and easy install if you're using AM3's.
Even though the fan is not PWM compliant it works on my mb using the CPU fan connector and having the BIOs set to Auto (ie PWM or Voltage). The fan speed varies based on heat.
- Cons: Cools well but has its limits, it is better than the OEM cooler and much quieter, but I wouldn't try to OC with this cooler. Save that for the 120mm or the new 140mm version (when its finally available).
Not enough clearance for RAM with heat tall heatsinks. I had to move mine, raising the FAN a few fins was not an option with my 128mm height restiction.
- Other Thoughts: This suited my needs nearly perfectly. Quiet, effective, and fit in the ~128mm space my matx case allowed. After spending about a month researching various coolers I selected this one. It was a good decision.
works great
- Pros: Small enough to fit in most cases -- the HUGE tower form core i7 heat sinks (158-160mm height) did not fit in my case that I've had for years.
- Cons: Flimsy fan clips. They work, but again are flimsy -- I had to take a pair of pliers to two of them to straighten them out. Of course I noticed I needed to do this AFTER trying to force them on (bending one of the heatsink fins in the process just a bit).
- Other Thoughts: This heat sink works GREAT and is compatible with 1156 sockets -- you just need to buy their separate mounting kit for $10. Hopefully folks that are looking for smaller heat sinks and not the huge 160mm ones read this and grab this along with Noctua's 1156 bracket kit.
