That won't last long without insulation. And how will it fit if you do insulate?

It will fit because I've planned this before doing anything. How well it will work, dunno yet, but going to do a test run later outside the comp.

Did a dry run. More pics and some numbers.








Forgive the long tubings, wanna see the worse possible scenario for flow rate. Still pretty good flow.






Crappy probe, a long story...

Didn't time how long it took but the GPU block's at - 0.1C. The pelt is an 80w run at 12v or so I think, my multimeter's completely wet and crapped ATM (another long story)





1.9C on the ram chiller side. A 65w here at ~12v. This side is completely uninsulated and losing a lot of the cold to surrondings.

Ambient's a really warm 33C (hot day today!) and the test was ran without a fan on the rad and it got pretty warm after a while, and water's at 40C after a while.

show us pictures after you **** up all your stuff k? and since ram doesn't get WARM to the tough lets alone need a pelt i find myself saying WHY??

but to each their own. course you can't bring silliness into these kinds of forums and not expect some flak

Bobmont, the thing is I would either go with just ramsinks or peltcooled and not the in between straight water exactly because they dont produce much heat. Thus to get a big drop in temps I'll need to chill it. I remembered reading somewhere that rams are Cmos devices or something and performance would improve as temp drops just like the CPUs.

the clothes pegs look ghetto, but to be honest, it may be interesting to see how it goes

Pelt cooling your RAM is unnecessary.

DDR RAM does not run that hot to start off with, and anyone who's actually tested RAM would tell you: even a heatsink has no/negligeable effect on performance.

You would have spent your money/time more wisely by simply getting faster RAM.

By Pelt-cooling your RAM, you've had to purchase:
-a power supply ($20)
-a Pelt ($20)
and you've spent an outrageous amount of time building a mount for it, which doesn't even extract heat evenly.

I'm sorry, but you're just wasting your time.

I agree with Brad, I want to see how it goes. To my knowledge no one has attempted this yet. So your statements about it being worthless are pure speculation. Yes ram does not generate much heat, and water cooling it to ambient is probably pointless, but chilling below ambient, which is what is going on here as is evidenced by the frost may or may not yield some awesome overclocking results. So I guess the point is that everyone should encourage this first attempt, if it does not work then you can bash anyone else who tries while pointing to this thread as proof. If it goes well then your going to look stupid when it's your turn to put a pelt on your memory.

prb123: I hear what you're saying, and I admit, I'd also like to see if it has any effect, but logic dictates...

In electronics, a bunch of things happen to components when their temperatures change. In this particular case, cooling down a CPU will yield results, wether it's cooling to ambient/near-ambiant temperature or below. However, memory does not need to be cooled in order to run, like a CPU does.

And so we get to the point: if a CPU had no cooling whatsoever, it would fry. So a cooling solution has to be applied, otherwise the temperature will reach a maximum (somewhere above 90C).

RAM never reaches its maximum operating temperature, with no cooling whatsoever, and that temp is already near-ambiant.

So if you cool a CPU (as you are required to do), you will get better results, because you're taking a temperature down from its maximum, by a good 50C, and in some cases, even more.

If you Pelt-cool RAM, you will simply take an electronic circuit from near-ambient temperature, to below freezing, in a temperature range where the circuit was NOT designed to run. You will not cool it by at least 50C, and you will not get better results.

I predict that the RAM will not work at all. I predict that the RAM will be damaged. I also predict that it will be too difficult to isolate it so that no condensation will damage the RAM or Mother board.

Now if we had military grade components, it would be a different story, as they are specifically designed to operate in a wider range of temperatures, but as far as I know, that just doesn't exist for RAM.

Can't wait to see the results...

A note on temperature probes:

A lot of these are not designed to measure temps below freezing. Make sure you read the instructions/specs (you know, that thing you throw out the garbage right away? )

I think it looks great. Total OOOhhh and AAAhhhh factor going on there. Even if it is pointless guys, we are forgetting what boredom and the quest for the elsuive megahert will do to a man.

I support 100%

Maybe I'll just make myself one, for shits and grins.

I predict that the ram will work just fine. Ive seen computers suspended in a 3m insulated liquid then liquid nitrogen cooled to -240c. It was one hellova overclock.

just food for thought.
