I am working on a project using a Peltier Heat Pump that I need to put a heat sink on. Now if I understand this correctly, the heat sink needs to exceed the rated wattage of the Peltier by at least 50% to promote efficient heat transfer. Due to the project this is going on water cooling is out of the question, and the Pelter is 140w so I need a Passive/Fan cooler for at least a 210w CPU. As my budget is a concern in this project (I'm poor right now  ) I was looking at this one or this one. If you guys have a cheaper or higher capacity option in the same price range, please point me in the right direction. Thanks.
Edit fix f'd up speeling

All you self proclaimed IT guys and accused laser printer repair men can't recommend me a heatsink after 2+hrs and 50 views? ARFCOM: http://cdn.wegotthiscovered.com/wp-content/uploads/Heavy-SON-I-AM-DISSAPOINT.jpg No. It's below my pay grade. |

Well I will just keep that in mind the next time someone says "ARFCOM mechanics please diagnose my dumb ass car for free please!!!1!"  People who write code for a living (for example), aren't going to know shit about heat sinks, or exotic PC components available in the enthusiast market. You're asking more of a hobbyist question. In corporate IT, nobody builds their own machines for the company. I've been in IT for my entire adult life, and I don't know shit about the fringes of PC building. It would be like me asking you (a mechanic, I presume) to advise me on track day tires. You may very well have an interest in this sort of thing, but I wouldn't expect you to. It's the same kind of thing.

The problem is your price range. At that range I believe they all perform pretty similar. If you can spare a few more dollars I'd recommend the Noctua dh-14. One of the best air-coolers you can find out there.

Actually any mechanic worth his weight in oil should know about performance (granted not to the extent of someone who works in a performance shop) as most owners of higher end cars (I work for BMW...) tend to have some sort of performance mod on the car and a lot of the time, poor installation of aftermarket components causes the problems they complain about. All the IT guys I've met to this point build high end gaming machines for themselves, but alas I am not exactly in contact with any of them so I figured I would ask here. |

The Noctua's are supposed to be very effective, if a little more pricey.
Noctua ETA: Oops. Duped naibaf above. (and yes, I'd be nervous about strapping that to my mobo too)

It's been a few years since I've researched CPU cooling, so I'll keep my comments more generic.
Copper will perform marginally better than aluminum and probably isn't worth the extra cost for you, especially if you can afford to trade some extra space to meet the cooling requirements. This will probably mean a bigger set of fans and a slightly larger aluminum heatsink. There is a point of diminishing returns, but with a Peltier, I would exceed by as much as I can, up to 100%. As I'm sure you are aware, be sure to have a good method to be able to remove the heat from your case, otherwise you are pulling it off the CPU but keeping that energy right in the case. Most of the trusted manufacturers (Coolermaster, Noctua, Corsair, etc) will meet their advertised specs, so the real choice for you is to match based on price, noise, etc. Cooler Master makes some good products and it looks like they have some that fall in or below your price range that may work for your cooling requirements (although they will be louder probably than the two you posted). |

I used this Noctua in my latest build: http://www.newegg.com/Product/Product.aspx?Item=N82E16835608014 Excellent cooling, quiet. |

Noise is not an issue at all, either is heating the surrounding air as the element will be used outdoors in the open. I came to the same conclusion about copper based on what I've read over the past few days. |

I have always liked Zalman fans
This one is nice The one that i use |

No mention of how much wattage those support but the all copper construction and coiled heat tubes make it look like it would work pretty well... |

I use a Zalman 9900 and 9700 and both work great for moderate overclocking while remaining silent. In reviews on more extreme overclocking, these do not perform as well because moving more air doesn't scale up their performance as well as the more extreme coolers. If I understand Peltier devices, they move not only the heat from the device they are attached to, but also produce heat themselves on the hot side. I would go with the Noctua, since it seems more capable of handling larger thermal loads, albeit loudly. Plus, even if the Peltier doesn't work out, the Noctua may do the job on its own. For regular PC use though, I'd strongly recommend the 9900. It sometimes goes on sale for $40. |

I can't find how much wattage they use, But you should be ok with any heatsink you go with. The heat sink that i posted that i use. Uses almost no power found a review of the ZALMAN CNPS 7500 Cu LED and they say The Fanmate 2 unit is rated for up to 6W power draw, and will output ~11V to 5V depending on where the dial is set to.
