The Hyper 212 is regarded as the best bang for the buck because it's often 20-30$, like that Micro Center link. For $50, I'd rather spend $10 more and chose something like a Megahalems (or that Spire Thermax Eclipse II).
I hear nobody ever gets the rebates from sunbeamtech. I bought the cooler cause I figured I would get it for $25 after the rebate, but I then read about how it is a major ordeal to try to get it from them or to get newegg to pay for it, so I e-mailed them and they just sent me an RAM approval and have waived the restocking fee because it is unopened.
I got the Scyth Mugen 2 instead, which was $40 at micro center (cheaper than shipping over newegg.
Yea i just choose the sunbeam even if i dont get my rebate if thats the worst about this product then its ok by me. On the frosty tech review it keeps the temps low and performs well and isnt too loud either. So hopefully i can mount it ok and everything goes well.
I pretty much just returned it on shear principle, and I probably won't be ordering anything from them or tuniq (one of their brands) for awhile.
The mugen 2 ranks lower on frosty tech, but it ranks higher on other sites. I am overclocking this weekend and I'll see how it does. I don't believe it is that much worst, and think there is a lot of results that can change based on standard deviation. Also, I think Frostytech's methodology has its own set of problems, for all the good it does.
