I want to watercool a few things....

[sandman001]

Alright, I'm running dual loop right now. One for the cpu, and one for the gpu.

I'd like to watercool my mosfets, my PSU, and hard-drive.

These seem to be straight forward enough, and I'm fairly sure I can do them with the tools available. I have a dremel with a bunch of attachments, a hacksaw, a table saw.

For the hard-drive, I pretty much just plan on one that wraps around it, and mounts in a 5.25" bay. Like, with some copper pipe soldered to some copper sheet that goes onto the sides and maybe the top of the hard-drive. Seems easy enough, unless there is a flaw in my thinking.

The PSU, I pretty much plan to cut down the heatsinks, and basically attach some copper pipe to them. I was thinking maybe some Arctic silver and some threaded rod and a couple nuts to hold it on. Or should I just use Arctic Alumina Epoxy?

The Mosfets, this could be the tricky part. As you can see here (http://www.xbitlabs.com/articles/mainboards/display/s754-roundup_23.html), the mosfets aren't ina lin or anything, and there are some caps and coils in between them. So, Any ideas how to do this?

I also have a picture representing these ideas, but it's too big.

you are going to try to watercool the mosfets? I'd like to see a pic when that happens :)

it's been doen before, but those mosfets were generally ina line, so easier to make a block for.

I've been doing some work on one of those anyway- power supply.

I am still doing some brain-crunching to figure out better ways, but I can give you a report on my "quick and dirty" method: it works just fine. :)

All I did was make a (mostly) U shaped loop that I fastened to the top of the heatsinks with cable ties- dropped just about 10c in the psu and case temp also went down (in an mATX case with full-size ATX power supply.)

I have more ideas on how to do this, but I think my next test will be using thermal epoxy to attach the tubing/block.

[sandman001]

did you use anything to transfer the heat? like AS or anything?

If not, and you got good results, I might simplify it, by just using zip-ties and some thermal compound. Basically what you did.

rogerdugans, when are you gonna pust some picks of this Matx you keep talking about??

Im working on A WCed lan rig now....

would also like to water cool the psu

lol- I need to get off my lazy posterior and post some pics!!!

Allrighty: I have a couple of things I need to do to improve airflow today anyway- pics WILL be up.

Please harass me with pms If I don't! :D:D

AS far as what I did for improving the contact between tube and heatsinks.....
nothing (yet). ;)

I had the system built and configured so I did a quick'n'dirty job.
I will be improving on it at some point, but one of the things I need is a 2 1/2 " pulley for 5/8" rope: I need to make a tube bender that will do TIGHT radius smoothly.

Thanks Roger, I will jsut do that, as I think it poses less of a risk to my nice new PSU.
