Summary: Maybe you can somehow disable the blue LED. I dont know. If you can its a 5 egg heatsink.
Pros: Excellent cooling. Small enough to fit into a rinky dink case and still have some clearence. VERY quiet. Maybe its my blown out eardrums from all the IEDs but i cant hear this thing running even under a heavy workload. Perfect for that HTPC you have your eye on.
Cons: Blue LED you cant turn off and its just bright enough to be annoying.
Summary: This HSF is being used on an Allendale 2.0GHz and is more than adequate. On a side note, Silverstone makes good stuff (at least the products I've purchased so far). I own two of their cases and love them!
Pros: I've been shopping around for a good CPU heatsink/fan to use with my HTPC. This was the third one I bought and likely the last. It's small, cools very well, fits fine within a mATX case and is fairly quiet.
Cons: The motherboard has a fit occasionally when powering up with this fan. It spins slowly... Too slowly in the motherboard's eyes evidently. At first I was concerned, but I kept checking the temps and all was well. I blame the board and not the fan... It's not like it's a big deal, hit "F1" and it boots normally.
Pros: Low profile is a great fit in mini-itx cases and small rack mount units. Fan runs quiet.
Cons: Not really suited for high temp environments. In my mini-itx box, it just couldn't push enough air and reached 170 degrees before I pulled it out. This was on a X3220 mind you, so not exactly a low power usage CPU. I would say snatch this guy up for CPUs with low thermal envelopes.
