Try the highest-powered peltier you can find and give it your PSU's 5V rail and see if that works. They should be pretty efficient at low voltages. Don't forget the anti-condensation insulation just to be safe. This is a lot of work, but if you can TAKE UP THE CAUSE we will thank you for it. The ide...

It is so big! Not portable at all! Zalman users can get another Reserator radiator for dual radiator. My computer is passively watercooled also, but it is internal and portable using the CORA 642 passive radiator from Alphacool. It is a different design from the Reserator and much more compact.

Yeah the OCZ does seem a better value. However, the Venice platform supports DDR500 (PC4000) without overclocking. There is an option for it on all Socket 939 boards. On dual-core CPUs the memory speed is very noticeable, but not on single cores. If you are running dualcore you might want to conside...

I'm using the crucial ballistix and it works great! It can easily do CL2-2-2-5 at PC3200. All PC4000 can do slower clocks with better timings. However, the memory does get pretty hot sometimes, hotter than BH-5.

No need for speculation. Passive cooling via peltier has already been shown to work well, especially with low-power CPUs like the 90nm Athlons (overclocked=55W). The trick is to use low voltage (ie. 5V from PSU), but I think the sweet spot would be to use 7V from a 350W Peltier. At 14V full 350W, th...

Doesn't installing fans to a watercooling system defeat the purpose of silent watercooling?

it's a closed system so none of this matters. you don't even need a res as mentioned above. however, water can evaporate slowly through the tubing, so a small res is a good thing.

I'm just judging by SPCR ratings. They gave the Enermax a 6 in terms of noise while the Seasonic S12 gets an 8.

If Romania doesn't have popular SPCR supplies, what about the Tagan and Epower stuff? I heard good things about them.

The Akasa Paxpower I cannot recommend since its max efficiency is only 75% which is poor. Their claims of 18dBA is very difficult to beleive due to this fact. The biggest reason you should avoid this PSU is because its 12V rail is 11.65V at idle, and around the same for load but maybe even lower. Th...

Ahhh so you don't work for CM, sorry I got confused. Welcome to SPCR.

I like Cooler Master's idea of running the Zalman 9500Cu "passive" with a nearby 120mm Nexus fan, with ducts to direct air. How would this compare to the Sythe Ninja "passive"?

SPCR reviewed a bunch of 2.5" drives. They indeed smoke the 3.5" ones, but are still loud. If you put your ear next to one, they still sound like helicopters. But they don't get hot so you can muffle them in thick foam and double muffle them in thick lead or uranium.

And that's the amazing thing. The XP90C seems to outperform the XP120 at around half the CFM. You guys better check my bold claim, but according to my tests and those of some others it seems to be true.

How does this compare to S12 under 150W? S12's are really loud if you put your head inside your computer and listen, so hopefully this provides a cheap alternative that is more silent. I modded a Nexus into a Super Tornado once and got that low-20's dBA down to 17-18dBA. waiting for review.
