Summary: 2. No automatic speed control. My BIOS has options to run the CPU fan on low and only ramp it up when things get hot, but the option seems entirely incompatible with this product. Runs at 100% the whole time unless I manually slow it down with the (included) controller, which then means it won't speed up when needed. And yes, I am plugging it into the right spot on my motherboard.
Pros: Nothing I can think of.
Cons: 1. LOUD - Let me clarify by stating I bought this for an HTPC build, so low noise is crucial. On anything but the lowest speed setting, this thing reminds me of an old, off-balance CD-ROM drive. That's the exact sound I think of when I hear this spin up.
Pros: I choose this cooler, because the fan actually faces the side window of my PC case, allowing the glowing LED FAN to be more visible. The blue glow nice & bright & sexy! I ran this with an AMD Phenom II X2 550 & I never had any heating issues.
Cons: Not compatible with Phenom processors that uses 95 watts or greater. I have to ditch this cooler in order to upgrade to a 6-core processor.
Pros: Does the job. Looks real nice and is very quiet.
Cons: Awkward installation for AMD users. The Intel spring clip is installed by default so the AMD version has to be installed in it's place. That means the fan has to be removed from the heatsink part. Not very hard but it took patience. The trick is to line the clip up in the channel and hold it while the screws go back in it.
Summary: *The heatsink fins can be bent easily if you're not careful, but you can just as easily bend them back if you accidentally do so not really a big deal.
Pros: *Keeps CPU cool.
Cons: *I would have taken a half egg off if I could but this is mostly user error: switching the latches from the Intel latch to the AMD is kind of a pain and you really have to make sure you don't mess it up otherwise you can't push it down to lock.
Pros: It looks good, easy to install if u follow instructions. Easy to mount in AMD 2.
Cons: In my system is not running higher than 715 RPM, ..it should run at a higher speed.. There's only 2 degree diferential temperature between this cpu cooler and the cpu cooler that came with my system. In other words , my system use to run idle 52 Degree and with moderate load 69 degree, and after and installed this CPU Cooler i only get 50 and 67 degree respectively.
