    Default Water cooling the PCP&C 1KW - Looks easy!

    Ok, so everyone knows that PSU's get freakin' loud as hell when you start to tax them. Jonny remarked that the PCP&C 1KW was particularly bad.

    Then we see Koolance making a PSU with a self-contained water cooling system that looks sketchy at best.

    So I'm thinking, 'Why the hell doesn't some company release a powerful PSU that you can just plug into your existing water loop?' Then I start leafing through Jonny's reviews looking for a PSU with internals that might be easy to fit a custom water block to.

    I find this.

    Doesn't get much easier, does it? Hell, you might not even need a custom waterblock - have a look at these HDD coolers:
    Alphacool.
    Asetek 1.
    Asetek 2.

    There probably isn't enough headroom to close up the stock casing with the water blocks in there, but cutting out a rectangular chunk of the casing can be done with no skill required. If you have a case that mounts the PSU flush to the top, you might have a problem, but for cases like the G70, TJ07, etc. the PSU either has headroom or can be mounted sideways.

    And that's all you need for a water cooled PCP&C 1KW silent monster.

    So Jonny, is there anything I'm missing here? Is there a hidden internal heatsink that I'm not seeing that wouldn't get enough cooling and fubar this whole idea?

    Otherwise, I see that there are a bunch of threaded bolt holes in the metal heatsink mounting plates and some PCB with soldered contacts that might get in the way - can you tell me how feasible you think it'd be to actually get one of these HDD coolers mounted (somewhat) properly across those bare metal plates? Maybe three copper shims could help you out?

    Anyone think this could work?

    There's more to cooling a PSU than just cooling the heatsinks - other parts need airflow as well. Mag-amp coils on the secondary are also big heat producers.

    Unless a PSU was designed at the factory for water cooling, I don't think I'd try to do a mod. Especially on something that costs as much as the PC P&C units.

    Right. The Koolance is actually a liquid BATH for that very reason. You could water cool the tops of those heatsinks, but you still couldn't eliminate the fans for the very reason OKW provides.

    Arg.

    Ok then, that's not that bad - I mean, the fans are temperature controlled, right? So as long as your water loop is keeping the temperature sensor happy, you can live with the fans because they'll always be on the lowest setting, even under load.

    I'm not just some crazy guy out to water cool everything, I'm just trying to figure out a way to get a powerful PSU to be quiet under load. Tell me there's hope, Jonny!

    try changing the fan, if its outside warrantee of course,

    or dangerous, altering the fan control so it doesn't go as fast..may require specialist knowledge, or more simply, try spreading the load with multiple psu's, we have had processors and graphics cards, next its psu's to be duplicated.

    bizarre!!! running your pc off a cooker ring main....it won't be long, 40+ amps at 120/240 volts!! we may need it for 8 cores, 4 graphics cards, ad. infin.

    uk mains wiring std. is 240 volts at 13amps max. which makes a smidgeon over 3000 watts max., so room for 3 big psu's off one socket, running maxed out

    what's the power or current limit in the US for domestic normal stuff? Is it double our current, ie around 26 amps at 120volts, giving the same max. power? (power = current draw x voltage)

    The fan is a secondary issue, and could easily be changed if it were too loud. Warranty doesn't matter since it'd be void anyway.

    If I wanted to share the load between two power supplies, I could buy 2 500W units pre-made for water cooling. But using two PSU's takes up radiator room, hence this thread.

    I'm not a fan of high PC power consumption either, but I'm sure it's been discussed in other threads devoted to that topic.

    Koolance originally did have also a watercooled PSU, for some reason that just dropped off the face of the earth.

    I think your idea will work provided that you have proper contact and you still put in a very low rpm fan to cool the board down.

    At lower wattages, like the 500W, you can water cool because the components are not going to get that hot.

    For a 1000W, you'll need the liquid bath like Koolance or you'll need to combine water with air.

    I think Nicepants is on the right path.

    Interesting concept though. I'd like to see if designing a unit from ground up for WC would be feasable or not. Condensation in high humidity areas could be a big big problem.

    idea: 'packs' of water, sorta like the koolance ram blocks, but all inside the psu, connected together.
