I am looking into a passive water cooling system. I wanted to get something like the Zalman Reserators 1 V2 but I can't find anything. My PC is currently the loudest thing in the living room other than when the TV is on and turned up loud enough to overcome it. I have a FX-8350 with the stock cooler on it. My GPU is a HD 7850 2GB. When I game I OC it to 1.2GHZ GPU and the ram to 1475Mhz and then the computer gets really loud. My main hobby is cars. I have a spare 5 Gallon Fuel Cell, Plastic and never been used. It looks like this http://static.summitracing.com/global/images/prod/large/bob-10992_w.jpg
With a 5 Gallon capacity, I figure I would just need to get a a pump, a cpu block, nb block and a gpu block. My case is a MSI Nighthawk. I don't feel that I would need to fill it more then half way up, just have the return loop go into the top of the tank and like spray back into the tank to dissipate the heat and the feed come out the bottom, into the pump and then go into the case. If I need a radiator I also have a spare oil cooler that I can fit a 200mm fan on. The fittings on the oil cooler -8an and the feeds from the fuel cell are as well. The return line on top of the tank is -6an. So I am going to assume I would need some adapters :D I plan on running distilled water and using copper blocks. Still reading on if a killcoil or chem agent is better to run. Thanks

Chris you say you don't want fans but you did say.



If you wanted to use 5 gallons of water as a thermal mass the CPUs heat will heat the water over time, which will require a radiator as a stabilizer which was your intention of using the spare oil cooler as a radiator.

Manofchalks suggestion was for you to consider the aftermarket air cooler as it's heat pipe cooling design requires low noise producing cooling fans, with probably...

I think it would work, if you included the oil cooler. The main challenge will be getting the fittings to work.
If you are still looking for something store bought though, you can look at something like phobya 1080 with the fan mounts removed. Two of those would def work without any fans at all.

There's your problem. Slap a cheap aftermarket heatsink to it like a Hyper 212 EVO and see if that solves your problem before you go to the effort of jury-rigging a water-cooling loop from car parts.

I found some adapters on summit. So I should be good there.That phobya 1080 is awesome looking, and it stands up!



Wrong post? Pretty sure a fan with a heatsink isn't close to passive water cooling. Just going to get the fittings I found and go from there. With 4-5 gallons I shouldn't have to worry about anything for a while.

Don't want fans.



This is freaking awesome.

Manofchalks suggestion was for you to consider the aftermarket air cooler as it's heat pipe cooling design requires low noise producing cooling fans, with probably no more noise than your 200mm fan suggestion for the oil cooler.

I'll further MoCs suggestion by suggesting to you that a Noctua NH-D14 can be run as a passive air cooling solution with no fans on it at all, I actually used it passively in the cooling fan roundup.

http://www.tomshardware.com/forum/331629-28-cooling-roundup-2012

Testing parameters for performance temperature tests were done using an overclocked AMD setup, a AMD 965 Black Edition CPU overclocked to 3900Mhz which was the maximum overclock attainable to be able to run a Noctua NH-D14 heat sink in passive mode with no cooling fans at all for the Control Temperature. The Noctua in passive mode was able to be stabilized by 1 hr running of Prime95 small ffts at an Idle Temp of 30c and Load Temp of 56c, the control numbers. Each test candidate was then slipped into the center of the Noctua and the individual results recorded after a 20min Prime95 small fft run, idle temperature recorded after a 10minute stabilization period, 23c ambient room temperature was maintained with a +.5 or -.5 variance.

Now if you are determined to go passive water cooling I seriously suggest rethinking schmuckleys suggestion he provided links to, as the creation of such a setup is leaving out the maintenance, and what you would be actually getting into.

A water cooling solution open to the air is plagued with contamination problems, bacteria, dust, getting into the water blocks, etc.

I went through all those problems in the exploring below ambient water cooling thread.

One last thing, according to the Watercool website, this rad can be used passively.

The heat exchanger can be operated in any
position; there is no difference between
horizontal and upright orientation.
It is possible to operate the MO-RA3
passive
(without fans) as well as active (with fans). In
passive operation, the heat quantity to be
dissipated should not exceed 200W.

It can be side mounted to a case, or stand alone with feet the 2nd link shows.
