Cooling Down Hot Processors
DonnaMai writes "Face it: the only scorching hot thing you want with a chip is salsa. Any other overheating is potentially counterproductive, and can be downright damaging to the microprocessor -- or other components. This article uncovers potential ways to chill the chips."
The easiest way to keep it cool to not run Intel.
How do I cool processors? Simple: I underclock them. Even a 10-20% less MHzs is usually enough to get rid of a noisy fan, i.e. the most stupid idea in the history of personal computers. Most of today's computers are I/O-bound anyway (Moore's law) so there is no performance loss whatsoever. Seems like an obvious solution.

There was nothing new or innovative in the article, and it had the depth of Paris Hilton as far as actual real world cooling suggestions.
/. I forgot for a moment...
There are a ton of different solutions out there both onchip and off including aircooling via different heatsink designs, watercooling, peltier cooling, and self contained refrigeration units.
This article barely scraped the surface of anything useful or interesting related to cooling.
Oh wait, this is
The problem is software bloat.
If applications were coded as if there were actual restrictions, if speed and efficency were a consideration, then this would be a valid option. 90% of the processing power in a computer would only be used when playing a game.

The bottom line is, despite significant advances in hardware, the "User Experience" still feels as sluggish and slow as it did in the days of Windows 3.1 on a 386. How much does XP do that the average user needs that Windows 3.1 and Word 2.0 couldn't? Can you IMAGINE how fast Windows 3.1 would be on modern hardware if the drivers existed?

Software piracy is victimless theft.
if you want a low powered machine.
buy one.
but you'll still need to cool the high powered beast when you need the power, unless you would like to get some nitrous shitter that only could run full blast for 20 secs and then explode.

Does anyone else care that the submitter, DonnaMai, ripped off the article for his/her "submission"? How is it that on a website for nerds, we can't think of a way to at least paraphrase or summarize an article?
Crap, I say!
From the Slashdot summary
and from the first paragraph of the article itselfAside from the removal of one sentence and a slight re-wording of the last, this is word for word the introduction to the article. If you were to submit this in a paper for a college (or even high school!) class, you'd be a good candidate for a plagiarism investigation.
Once again, Slashdot editors, there's a very simple way to deal with this -- change the author attribution. Rather than saying, "DonnaMai writes ...", use "DonnaMai quotes ..." or "DonnaMai poorly paraphrases ...". By properly citing the summary as a quotation or paraphrasing* of the article, you would avoid the impression of plagiarism.
* Yes, paraphrasing is allowed by fair use. In fact, if you're going to summarize an article, you want to paraphrase. However, paraphrasing is not, "Copy a sentence with a changed word here, drop a sentence there." You need to write a summarization in your own words, not take the article's words and (poorly) "massage" them so that they're not 100% identical (90% identical is still a problem).
hm......
Double the number of registers?
I dont think so.
How about parity (one extra bit) and ECC? Its been in the communication world forever.
The "optimal voltage" is dependent on the foundry process and the threshold voltage associated therewith. Latest and smallest (90nm) sits at a power supply of 1.1V and has gate oxide leakage problems like you would not believe. After all the gate oxide thickness is about 6 atoms right now.
Running at reduced power supply voltage does reduce power, but the penalty is paid for in several areas: reduced driver capability, not able towork at the fastest clock rate, susceptible to environemnt noise, much more sensitive to analog issues.
What you are describing now becomes an analog design issue.

Yes, but they are solvents for the plastic parts used on the MB. Over time, the plastic parts (such as slot connectors) will swell, and eventually they might break the solder joints.
The pcb itself might swell, and if it does, it will break the plated thru holes and vias between the layers in the board.
I can't believe nobody has said this yet, but the absolute FIRST thing you should do if your system is running over-hot is check the airflow and direction of all of your fans.
Most ATX cases like to have a fan blowing in the front, and other fans blowing out the back, check your case documentation. If one of your fans isn't working well, or is actually facing the wrong way, the entire airflow scheme goes straight to hell. I've seen this happen several times, but now that cooling is so critical incorrect fan placement is often a show-stopper.
Today's story? My buddy builds a new system with a new P4 3.4HT. It exhibits classic signs of overheating-- the fan sounds like a 747 taking off all the time, odd beeping, memory errors, and when his brother who actually built it for him runs 3DMark, it scores something like 40% of what it should have on CPU. Everest says it's running at >80C. Much freaking out is done, and they order a hardcore Thermaltake fan to replace the standard/weak one that came bundled with the processor. That comes, and it helps somewhat, so the processor isn't stepping itself down to non-melting temperatures, hanging at 65-70C full-performance. Memory errors still a bit of an issue.
So I come over to look at it. Dumbass neighbor (Best Buy Geek Squad employee/Frat Boy) had put the front fan on facing backward while assisting with the assembly, so the front 80mm case fan was blowing OUT of the case.
I unscrewed the fan, flipped it around, and two minutes later the computer was playing Far Cry and humming along at 40C, by far the quietest computer in the room.
Moral of the story? If you have a misplaced or broken fan, your cooling power drops massively. It pays to actually look at your case documentation now. Oh, and buy Antec.
