I don't have a SLK-900 therefore I cannot make that judgement. I was in "heatsink hell" for a year doing nothing but reviewing everybody's heatsink they threw at me. Some were small, some had screaming loud Deltas, some had 60 dBA fans, some were very strange looking....

This is the best for clip mount, cooling power and noise that I have worked with.

I did work with a previous SLK version a year back and it was impressive at that time of testing compared to the rest. The advantage to the SLK is that different fans can be mounted to it. The stock fan is loud though at 55 dBA.

SLK PROS

- can put other fans on
- will beat the 7000A-CU due to the SLK having tons more CFM. But won't beat it by much.

SLK CONS

- is most likely more prone to moutning problems from surrounding motherboard components.
- is louder
- is harder to mount the sink and fans


Stock sinks side by side...the CNPS7000A-CU is better.
