Comment: Re:Liquid cooling for datacentres? (Score 1) 118

If you live in a desert climate, air cooling sucks and if the dust is not dealt with at regular intervals things fail quickly. First dust starts to accumulate on the fan blades (unevenly) putting it out of balance thus placing greater strain on its barrings. Meanwhile, intel's ingenious design of their retail cooling fan and heatsink ends up being clogged with dust. The ambient temperature inside the chassis begins to increase as the chassis fan and PSU fans have now ceased, leaving only the higher power cpu fan spinning faster in vain packing the dust more tightly in an increasingly overheating heatsink. With no airflow coming into the chassis, the first thing that usually goes is the HDD. And is usually the first time a service call is generated from a user.

In my server closets I buy my own chassis with an easy to remove air filter on the front of each chassis, about every month I take it to the sink rinse it out, shake off the excess water and put it back. The closets have their own independent AC and room monitor with alerting sophisticated enough if for some reason the AC quit Servers would begin treating it like a power failure and begin shutdowns.

But for the poor PCs sitting on the floor of 100s of users all working as digital air filters. Unless regular maintenance is done (the dust storm blow job with the air compressor) they crash within 6 months to 1 year.

I really like the idea of liquid cooling. Just leaving a rig that I'm setting up for some running 24/7 with 2 8800GTX, QX9770, 2 Seagate 1TB, 3, WD 150 Raptor, evga 680i mobo, Tagen 1100W PSU 2 19" Dell 2007WFP in portiat mode sandwiching their 30" model in the middle.
Compared to last year, my electricity bill increased by 40% for this month My Kill-A-Watt reader registered an average 600W, but the heat would activate the main HVAC in my house much more often. All in all to run this rig costs close to $100 per month in energy costs.
If I could easily get that heat outside of the home, then I would only be expending 600W for the computer and saving 3KW each time the HVAC kicks on.

Another thing, the Cooler Master CMStacker is a POS. At least in the desert, it is nothing more than a dust storm in a box. So far I am using a great quality filtered rackmount chassis, but he wants CM with pretty lights lights. I'll show him where to the canned air is in costco and how to make small dust storms on his front porch every month.

Sorry for not having much of a point, my ambien as begun to kick in and will be typing in my sleep soon.

remove office writes "After calls from several prominent bloggers and a couple of presidential candidates themselves, CNN has agreed to release the footage from its upcoming June presidential debates uncopyrighted. Senator Barack Obama was the first candidate to call for all presidential debates to be released under Creative Commons, with fellow Demcoratic hopeful John Edwards following shortly afterwards. CNN will be the first to do so with their June 3rd and 5th Democratic and Republican debates. The NBC-Microsoft co-venture MSNBC hosted the first presidential debates recently but refused to release it under Creative Commons, opting instead to post only commercial-ridden clips online in Windows Media format."

Tjeerd writes "Gordon's plastic wafer is the product of the latest in a long line of "cold fusion" experiments conducted at the US navy's Space and Naval Warfare Systems Center in San Diego, California. What makes this one stand out is that it has been published in the respected peer-reviewed journal Naturwissenschaften, which counts Albert Einstein, Werner Heisenberg and Konrad Lorenz among its eminent past authors (DOI: 10.1007/s00114-007-0221-7).

+ - Ahead of the Crowd- Fujitsu's LED Backlit Notebook

Submitted by Anonymous Coward
An anonymous reader writes "While everyone is waiting for the LED backlit Macbooks to arrive, a few companies already have products with this feature available. One of the most interesting of these notebooks is Fujistu's new ultraportable, the Lifebook P7230. This sub-3 pound notebook has a 10.6" LCD and has a battery life of up to 6 hours thanks to that LED and some other powersaving features (Fujitsu says it goes up to 9.75 hours when an extra battery is swapped with the DVD drive). Companies like Sony and Asus have also started to offer LED backlit models and soon it will be standard, but in the meantime the P7230 is packed with features and is cheaper than much of the competition."
