6x RAM COOLING - Factory Solutions vs. Custom

post #1 of 4
Thread Starter 
Please post shots. Post something you can buy, something you've installed, or what you've made yourself. Pls make the photos links to the shops where you found them if you can buy them, or post your own shots with air cooling already installed and tell us what you did.

I am considering custom rigging bigger fans if possible. 80mm fans might not fit, but they probably come close. So there has to be something in the 65-75mm range that would be the perfect fit to max air flow for hot rooms and high OC's. Mounting them might require some creativity, but there's gotta be an easy way. And keep in mind you could buy two more fans and chop them up for perfect shrouds.

I would love to have at it. I don't care it if is ugly, just want it to be quiet and well directed high-CMF.

Here are some 2 x 60mm fan systems you can buy:

And a 70mm x 15mm fan which I guess should fit in pairs over 6 DIMMs:

And here is a quieter 70mm x 10mm. Also could scrap two for shrouds:

Here is an other directly from G. Skill if you buy a pair of their crazy arse 4GB 240-Pin DDR3 SDRAM DDR3 2133 (PC3 17000) 9-11-9-28.

Probably not much of a bump from their Ripjaws X-Series 4GB 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) 8-8-8-24, but the memory sounds nice, and it looks like the cooling system is a 2 x 60mm.

But making shrouds would be very easy, just cut them in half and remove the fan intact.

attachment.php?attachmentid=205970&stc=1&d=1303004995

Then screw them on to the underside of your fans by using longer screws on the outside corners of your two unmodified fans, making sure the shrouds face inwards and face each other.

Then onto the first tricky part. Figure out a way to lock the two unmodified fans together using the inside corners (and/or by doing something fancier with braces).

Something ideal would be small custom metal braces. Just small flat metal bars that ran along the top of your two un-modified fans, with holes for each of the 4 screws on the fans. That would make it very solid if done with care. And mounting onto the MoBo should be no problem if you can manage that.

Then wrap the entire edge of both your fans and shrouds with black electrical tape, so as to seal the opening where the two halves are missing. Make sure to carefully tug on the tape so that it goes on with some tension. And cover the inside of the tape that is exposed with a second layer of carefully placed tape.

As long as the outside layer of tape has at least a little tension it should hold very well. There isn't exactly a lot of pressure generated by two 75mm x 15mm fans, lol, so for this use even TAPE should be ok. YMMV. All it has to do is hold together to keep the air aimed in the proper direction (straight down).

If you were careful, you should have a very efficient and strong shroud. Just don't bump the tape in the middle from under it when upgrading.


Now onto to the other hard part. You'll have to get the whole apparatus suspended right over your RAM. And make sure it is up to earthquake building code in case you live on a fault line. So I am thinking that a simple and easy idea might be the best idea here:

Scrap the legs off of one of these 2 x 60mm systems. Steal them for your own custom 2 x 75mm system! wink.gif


ALL IN ALL, this would give you about an additional 15mm of fan blade to spill over the sides of the out-most RAM modules, providing more even cooling between different RAM modules, and giving you a lot more even airflow throughout all of your RAM. Plus the obvious dB to CMF benefits.

Take it an extra step and put these on a dial. That way you'll be able to find the dB sweet-spot for your case. Making sure it isn't heard over the rest of your cooling, but making sure you are right up against that mark to get the max inaudible and even airflow over your RAM heatsink and spreaders.

Maybe the leg off a Zalman ZM-RC1000 would work. They are "only" $20 and it would look nice... though I would much rather come up with a way to make a custom one so I could claim it was all me.

This leg already has a contour designed into it where the side of your shrouds would rest. This is how the 2 x 75mm would be held up.

From looking at this picture I am not sure what the bottom screw is for. But the top screw seems to be tapped into the actual side of the fan casing. I don't have one of these so I don't know if this would work. But it looks like it should.

So use the top screw on the leg, and drill a slightly smaller hole into the side of your fans. Just make sure not to damage the blades of the fan while drilling this guide hole, and make sure not to drive the screw too deep through it so that it might get in the way of the fan blades when you turn 'er on.

A little super glue or some other adhesive could help make it solid, just sand down the surfaces a little. And if you apply it from the underside you'll never see it.
