While having two fans one one heatsink can have it's advantages i don't think this cooler would be very effective due to the design. Even though the heatsink has two fans there is still a 'blind' spot directly in the center where airflow is needed the most! On the plus side, 4700RPM is fairly fast but at close to 37dB, it would be quite loud.
i have another question as well...this is a concept idea would it be possible to cool a CPU using compressed CO2?...i mean spraying it across the cpu in a slow controlled stream and then using a small compressor to put it back into the tank...i just remember when i used to paintball how cold those things were after you pulled out a cylinder..i'm pretty sure that was due to the co2 contacting O2 and having a thermal reaction. So maybe the same effect can be duplicated and used for overclocking...just a thought, tell me what you think.
what about this one? - http://cgi.ebay.com/Performance-Hea...ryZ80149QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
In theory, yes. But it would be difficult to design and maintain and to not damage components, not to mention probably expensive!
http://www.newegg.com/Product/Product.asp?Item=N82E16835150010 that's a good heatsink, no small tiny fans spinning at 4k+ rpms. A lot better design for cooling and there's a lot more airflow.
Not too sure about this one. Simple design but i don't know how effective it'd be with the fans mounted on the side, as the air still would'nt be cooling the core of the sink! I may be wrong but it seems like a ineffective design. Plus the same as before - noise. Unless noise doesn't bother you!
well, i have built similar systems (my dad was an ac repair tech) on a small scale...like i built a mini fridge one time...but freon, that would be tooooo cold i think, co2 could work if regulated correctly and i could design a fairly cheap cpu cooling system using this method (that is assuming my theory is sound) the part that actually cooled the cpu would have to be airtight, the cylinder containing the gas would not have to hold high pressure (due to the compressor keeping the co2 moving consistantly) and i think there are suitable aquarium pumps out there that could run off 12v and effectively cool the cpu using this method...
Ninja, helpful again...i think that is within my price range and it looks like a solid design, thanks for the advice...
what's actually better than any air alternative (in my opinion) is the peltier effect. One side gets cold, one side hot. Cold side on copper plate touching CPU, hot side mounted with a big, quiet heatsink. The best setup would have it turn on when the CPU hit a certain high and stop at a low.
i like that HSF you mentioned ninja, the only problem is my mobo...the cpu is surrounded by capacitors.
It's pretty creative, but I'm not sure if CO2 get's cold enough to do the trick or can transfer heat away like water cooling or be freezing cold like a liquid nitrogen setup. Besides the transfer medium (H2O or LN2), you've got to consider the design of the setup. What you're describing as a setup seems to mimic a watercooling-style setup. While the pumping would do the job, you'd need to dissapate the heat somewhere along the line. Quite honestly, I'd see about finding a stock cooler for the socket type you have (Socket 370, 478, LGA775) and just using that if you won't be overclocking.
Hi Just little input here - If you are willing to go through all the trouble of CO2. Why not go for water cooling? It has to be cheaper than trying to adopt gas cooling and also everything is already out there. Just buy and install. No?
the CO2 thing was just an idea, i'm not planning on using it i might build one just to see if it can be done because thats what i love to do. And yeah, the system setup would be much like that of a water cooled device i think for heat dissipation a copper coil could be used (a very small one) not sure if it would be as efficient as water cooling but maybe it could...i'll just have to do a little expirimentation.
