How many RADS does it take to cool a PC fan less.

Ory!
 Share

So I got the idea to cool a CPU/GPU/RAM by pumping all my liquid through a bunch of RADS with no fans I got my idea from JayTwoCence's video "This is the dumbest thing I've ever done...". My question is how many rads would take to cool a CPU, or more specifically how many watts can a single fanless RAD dissipate? My idea is to make a completely silent system by sealing my pumps in a box lined in a noise dampening material, to achieve the ultimate quiet system. The only part I haven't figured out is the power supply fan if you have any solutions please give me some ideas.

LTT made such a thing a while back but too lazy to find the link. Also, Seasonic makes fanless PSUs

Just FYI, "rad" is just shorthand for radiator, it isn't an acronym :)

honestly if you want to go fanless, oversized heatsink on a caseless system is the best.

There is a decent amount of math you would have to do here, calculate the surface area or the radiators, find out what temperature the liquid will be, calculate the heat transfer from the radiators to the ambient temperature of the room.

 

Maybe google a thermodynamics 101 course to try to figure it out

Somebody already mentioned fanless psus, but if you buy an extremely overpowered psu relative to your hardware the fan won't need to spin because efficiency.

 

Wow that sentence degraded quickly.

Or it won't click on the fan until it gets hot if you run out at 70% or more

not sure, i know a MO-RA3 360 from watercool can cool passively and that's pretty much 3x 360

still depends on a few things like input load, and ambient air temp and air movement.

I tried running my system passiv and works on idle (web browsing, watching videos, etc.) but under load the water temperatures increase slowly to about 35 to 40 °C which is the point where i turn the fans on because i don't feel comfortable with such high water temps. Roomtemperature was around 25°C.

Usually a truly fanless large system would use chilled facility water. For a PC, it would be easier to just run monitor, keyboard, mouse and audio cables into a soundproof room than to have a massive and extremely inefficent cooling system with fanless radiators.

 

The other issue is how many variables there are involved. Since the heat is passively dissipating to the ambient air many times slower than it would with even a low speed fan, youd need to know the maximum continuous heat input to the system, and then calculate the maximum dissipation to the ambient air at a given ambient air temp.

 

Then youd need to imbalance it in favor of heat dissipation so youre not putting more heat into the system than can be removed passively.

 

Which of course means huge amounts of mass and volume to get the necessary surface area.

 

To all those suggesting fanless PSUs: those usually specify installation with adequate airflow from the case fans.

 

I think a case with extremely quiet low speed fans and acoustic absorption panels would be a much more effective solution. They do make purpose built cases for silence with extremely quiet fans for liquid or air cooling setups. It wouldnt be 0db to have the pumps for the radiators either, so even if it was fanless it wouldnt be noiseless so making it fanless becomes rather pointless.

 

You could also use something like this to control any fan noise that does manage to escape the case.
