Water cooling your PSU

I'm looking for anyone with advice on attempting this mod and if anyone has experiance and or pictures that would be great. I am planing on making my computer as quiet as I can, and the fan on my PSU is quite loud even with the speed cranked down (it's actualy starting to die too... i may get a new PSU with a bit more power, but still don't want the fan)

Also I want to put a waterblock on my 9800pro AIW and can't find any good info on either what block would fit, or how to mod other blocks to make them fit (i have seen referances to people modding the DD video block, but all the links are dead or the post is just no good anymore)

Thanks :)

*sigh* it sucks the forum upgrade ate my write up on this, I'll see about rewriting it.....

Yeah it did, I was wanting to read it too.
 
Copy cat... ;)

Here's my thread on the subject.

Go take a look though, seriously. I have a solution in there to keeping your heavily loaded PSU cool without going water. Sure, it doesn't have the "cool" factor that pumping water into it does, but it's quick, easy, and quite effective.
 
theres something about running water thru a psu with 120v that alarms me...
 
It makes a LOT more sense to get a fanless or really quiet PSU than to watercool it.

Just kidding bro...

I know :)

alot of people say that about WC the computer. "Gee, something about running water through my computer alarms me..."

those folks lack the [H]ardness

and your point is........?

and what if we don't have/don't want to sped the $$ for a fanless PSU? Or like the one we have, just want it totally quiet? And maybe we just want to do becuase we can......


I think I'l rewrite my PSU tutorial this weekend and put it back up. I also have another PSU I want to WC, I'll do a write up on that as well. It will be done a little differently than my others, a little more polish and less ghetto methinks :D

no its not that, i have watercooling, its just running water though my psu that i dont like...thats like having a watercooled toaster.
 
fanless PSU are not better than a watercooled PSU, as the fanless PSU will dump ALOT of heat into the case and raise the overall system temperatures (yes a watercooled PSU will raise water temps, but not by enough to really matter)

I have to disagree there. My PSU usually shows a temp of about 34c. Under load (two Prime95's running producing the maximum ammount of stress and heat) it can go as high as 51c (59c before my cardboard "tunnel" mod in my there- see above link). We all know that as PSU's heat up they drop in efficiency and output. A 520w PSU that outputs 520w @ 35c might drop as low as 400w @ 55c, so in that sense it make perfect sense to water cool a PSU. If you can keet it to even 40c and have it's output not dip below 500w you are much better off, especially for those that are OC'ing and have a lot of devices.

I still plan on water cooling mine, and have devised a plan from looking at water cooled PSU's, both modded and commercial units. I want mine on a seperate loop though, and plan on using an red for an 80mm fan and a small Eheim pump. The whole thing will fit in the top two drive bays of my system (where the cardboard tunnel is now) and won't pull any air from the system. It will get air from in front of the case and pass it through the PSU and rad (which may reside outside the case and behind the PSU).

Unlike with a CPU or video card, where heat will hurt your overclocking ability, nobody cares if the PSU gets hot. As long as it doesn't cause instability (and if it does, you need a bigger PSU, not just to make your current one more efficient) the PSU can get as hot as it wants. As far as dumping heat into the case, if you're watercooling your internals it won't matter because everything else can be warm no problem.
 
The PSU will generate less power at a higher temperature then at a lower temperature. One of the things that overclocking in most cases requires is a lot more electricity than a stock clocked processor. While a bigger and beefier PSU should theoretically take up the slack, some people don't want to risk it. There is nothing worse than showing up to a LAN with a super-overclocked FPS killer machine and finding out that a sudden increase in temperature makes your stable overclocks anything but.

That said, there was some guy who watercooled his entire machine and actually made waterbocks for the PSU. I think it was called the "Stealth PC" or something... he was running one 120mm fan to circulate stagnant air and that was it. He even watercooled the drives. It was amazing, everything was lapped and a mirror finish.

Well, I care because at 60c+ my last power supply, a $175 PC Power & Cooling 510w plain Jane ATX PSU cooked itself to death from the heavy load, and they are supposed to be the best. If the cooler the better for the CPU, why not for the PSU?

umm, no. my write up was done in feb of this year. ;)

Hey, I just realized... I was talking to the thread starter, not you. LOL...

You really do need to post that again though.

Something was wrong with it or you had it next to the fireplace. Your system did not overload it.
