Submission + - Intel's liquid CPU cooler: Is water worth the cost (extremetech.com)

MrSeb writes: "When Intel launched its high-end 3960X CPU last month, it also debuted a new liquid cooling solution. Typical boxed Intel CPUs ship with a heatsink+fan, but the company noted that the majority of its enthusiast customers bought third-party solutions. The new liquid cooler — it goes by the inspiring moniker of RTS2011LC — is meant to offer enthusiasts and OEMs an Intel-brand solution they’ll actually use. But is water cooling really necessary? Like its quad-core "Extreme Edition" predecessors, the 3960X still dissipates 130W — and more tellingly, Intel even states that it'll be releasing a sub-$20 air cooler for Sandy Bridge-E and Ivy Bridge-E chips anyway. So is it worth plunking down $85 for the new RTS2011LC? Does it provide the kind of performance that Intel's stereotypical "enthusiast" customers need? ExtremeTech goes hands-on to find out."

Few foreign governments expect the US to police the world. Taiwan, Israel, South Korea, Saudi Arabia, yes... certainly not Pakistan or Nicaragua. Most countries don't really want the US to play that role.

Social security expenses usually return to the domestic economy, buying american food and houses. Military expenses usually go to 1%s or foreigners, which store it away or spend it outside of US.

Comment Re:Tap Energy of Volcano? (Score 2) 469

IANAG, but I think removing heat wouldn't make such a difference.

There's some process in the mantle feeding this area, adding mass to it. The biggest problem is pressure, since that mass is used to compress the volume under the volcano. When the rock shatters, that pressure is communicated with the surface and then there is an upward flow.

Refrigerating the volume of rock under the volcano won't change much of its pressure.

From a geoengineering point of view, I think that what's necessary is a controlled eruption to alleviate the pressure. But I have no idea how deep it would be necessary to drill.

I would really appreciate if a geologist could correct me here (I'm a mechanical/petroleum engineer)

That money should be used to fund public universities. The government is a much better negotiator than individuals, because the government can fund the entire university itself.

Bad analogy: with a hundred thousand dollars, you can buy an ice cream truck, freezers, ice cream ingredients and hire one person to make and distribute ice creams for a summer. And that's a damn good ice cream truck.

Now show a hundred grand to someone selling ice creams and tell him you will spend that money on ice creams during the summer. And you will buy all that ice cream only from him and negotiate the price daily. Soon you will be buying 100 dolar ice creams cones.

Men demand sex and women demand security, but those are necessary conditions, not sufficient conditions.

Men won't date someone who won't put out or isn't minimally attractive, but once certain minimum requirements are met, men will demand mental or emotional attributes from their partner, besides the sex. For some men, though, those attributes are to shut up and take care of the house; others will be happy with someone who just isn't batshit crazy; and others demand a loving and humble rocket scientist.

Women won't date someone who can't or won't provide, but once minimum requirements are met, etc...

Of course those minimum requirements depend on the person, and those usually depend on how much that person can provide sex or security for their partner.

(...) we predicted the interests and Social Security numbers of some of the participants (...) the goal of Experiment 3 was to show that it is possible to start from an anonymous face in the street, and end up with very sensitive information about that person, in a process of data 'accretion.'

Comment Relativity still holds (Score 3, Informative) 412

The theory of Relativity still holds true, what this experiment (if it's accurate) changes is our idea of matter and causality: if neutrinos have imaginary mass, they are allowed to traver faster than light, as tachyons; and causality may have to be revised, from a onward moving arrow to a regular dimension, in which the future can influence the past.

Petroleum engineers have the best starting salaries. And we will be using oil until you retire.

Mechanical engineering has a lot to do with it, so it won't be a huge jump.

I did this myself, I am a mechanical engineer and I'm working in petroleum production now.

Many oil companies define themselves as "energy" companies now, meaning they also have bussiness in renewable sources. They also research on energy efficiency. Of course the big chips are in petroleum technology, but still those companies wan't to remain relevant when fossil stops being our main energy source.

Many governments give aid to renewable energy generation technology, and government contracts can sometimes be very favourable to the private sector.

Automobile engineering isn't a bad field to work in, but energy certainly has better opportunities. Energy companies will pay you full salary to do a doctorate in their field, for example.
