Silent Pump for Water-Cooled PCs
Wycliffe writes "New Scientist has an article about a silent pump for water-cooled PCs.
The system, developed by a Californian start-up company, aims to silently solve the problem that the faster chips get, the hotter they become."
When are they going to move to water cooling for video cards? The GeForce FX fan sound can be compared to a vacuum cleaner.
My sig can beat up your sig.
These guys have been selling this for a while. I have one and it's awesome. Use it with CompactFlash to boot from, and there is absolutely NOTHING that spins or moves, so no sound at all. Great for your home entertainment system.
Unfortunately they don't support the very high end CPUs. When I bought mine the max was 1GHz PIII, which is still ample fast for most apps.
1)The processor is hot, the environment is cold.
2)This differential could be usd to produce energy.
3)Recovering some wasted energy may increase battery life.
Ok, just looked up and did the math. The theoretical maximum efficieny of an engine is
(Hot Temp - Cold Temp)/(Hot Temp)
with all temperatures in Kelvin.
So if you're at room temperature and your chip isn't melting, the maximum efficiency will be about 20%, unlikely to be enough to bother about.
Should I tell my friends and co-workers to avoid water-cooled solutions until the noise problem is solved? Seriously, when did water pump noise become a problem? There are very reliable and quiet water pumps out there. Here's an example: http://www.petguys.com/-015561105650.html This pump runs for years without any maintenance. IMO, this brand is tops, most all are very quiet in airless mode. This particular model pumps 270 gallons per hour (283ml per second), and costs $18.99 mail order. I've had several that have run for 4+ years without any maintenance. Also, this is the mid-level pump from this manufacturer. There are several that are smaller, and quite a few that are larger.
