Any reason to water cool a power supply?

post #1 of 27
Thread Starter 
This may seem absolutely insane and might be something that most users just simply ask WHY?!? but i say why not?
I know power supplies have small heat spreaders on the internal components, presumably to cool off whatever bits get warm, (you can tell i am no psu expert). So my thought is, could there be a water cooled power supply?
I am not saying PSU manufacturers go out and start mass producing these things as that would be silly and there would be little if any demand for such a product. This is entirely a what if thread.

Lets think about this for a sec, you have water cooled CPUs, chipsets, GPUs, hard drives, and I have even seen people water cool raid cards that get too hot. With that being said what if there is one insane user out there that just wants to water cool every last inch of their PC? thoughts?

That's a huge disaster waiting to happen. Can you imagine what would happen if you had a leak (or worse) inside the PSU? Not only that, but someone would have to manufacture special blocks and fittings for various PSUs.

I remember koolance had some psu's that were watercooled (230w LOL, 1000w, 1200w & 1300w 110V AC/ 1700w 220V AC)
They seemed to work quite well.

Nothing wrong with water cooling a PSU. The reason to do it is to have a quieter PSU by removing the air cooling an installing a cooling plate directly to the rail(s) which in turn allows the Caps to run cooler.

Personally I would just go the route of overkill and get a PSU with more wattage than the system needs which allows the cooling fan to ramp up only when needed. Yeah it will cost more but it's the easiest way I know of to keep the dB level low. thumb.gif

As I said gents, this is strictly a what if thread smile.gif

I've actually been thinking about it for a while; but my reasoning is slightly different that just wanting to go overkill.

I have a SuperFlower fanless PSU (well actually Kingwin, but the OEM is SF), which I quite love. I dislike many PSUs because I simply don't like the fans they've put inside them; but I don't mind fans if they're super low RPM and I get to choose them. I'd love to hide my PSU away in the case I'm building, but it's not realistic if I'm going to be using a fanless power supply because of airflow restrictions.
Then I spotted this:

Might stick this and an inaudible 92mm fan on the power supply and then hide it away.

I understand the grave consequences should it leak during use, but I've seen many people on this forum who seem to react as if it has as higher chance of leaking than regular water cooling components. It's as if they're getting over the new watercooling user's fear of leaks all over again, but this time for just one component. For leak testing you can just use an external/spare power supply, or leak test the block prior to installing it, or just leak test it with air instead of coolant. My point is, it's just as likely to leak as the other watercooling components. If you're confident that your other components won't leak, then there isn't reason to think this PSU block would leak any more than those other pieces.

TL;DR:
obsessed with noise, could cool fanless PSUs in more closed areas, Alphacool makes block.

Hell yeah. Even though my PSU fan is equal to or quieter than my radiator fans I say why not. I bet you could modify a universal GPU block to replace the PSU heatsink.

Maybe not... You'd need a custom block somehow me thinks.

Zalman once had an overpriced line of power supplies that used heatpipes and a fin stack for extra cooling on one of the heatsinks, but with a fan:
http://www.hardwaresecrets.com/article/Zalman-ZM600-HP-600-W-Power-Supply-Review/402/3

Some fanless power supplies have heatsinks linking up with a large heatsink up top, like the aforementioned Super Flower fanless models. You could stick a rad where the top heatsink goes. See here, and page 4:
http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=244

I mean, it isn't that difficult to design heatsinks for the major active components (the ones heating up the most) and/or blocks that could transfer heat out for a water cooling loop. An issue normally with fanless setups is that components other than the heatsinked ones (like the capacitors) aren't too happy with high temps and heat up considerably based on proximity to the active electronics. But if you're able to draw the heat away from where most of the power is lost via liquid cooling, then you'll have lower temps throughout the internals. A little convection would probably be enough to cool the rest, even for kilowatt power supplies and higher.

Already made a couple years ago, seems abit more useful then watercooled harddrives but still pretty pointless.
