I am designing my watercooling setup, and I have come to a bit of an impasse. The setup will include a dual opteron setup on a Tyan K8WE motherboard. I will eventually be upgrading to a dual nvidia 7800 setup. Here is the situation: I have opted for the swiftech storm waterblock for both...

Huh? You need dual-link DVI for the 30" Apple Cinema Display. It WILL NOT WORK without it. Quality/performance has nothing to do with dual-link. Dual-link is simply the answer to the problem of not having enough bandwidth for the extremely high resolutions that the 30" ACD requires (or any...

Question: why are all the reviews maxxing out at 1600x1200? If this card is excelling at these resolutions, why aren't they cranking up the resolution to something higher? Apple cinema display 30" resolutions?

Your argument has a major fallacy. In programming multiple threads in a scientific model, synchorization doesn't have to happen in real-time. You apply the model, split the processing, and if one process ends up finishing before the other, it can simply wait for the other processes to catch up...

Are you overclocking? Are you looking to increase your internal RAID array? Are there any upgrades to the video requirements in the near future? If you plan to keep your existing setup, I'd go with PC Power & Cooling 510. If you plan on increasing your power requirements significantly...

AMEN to what DougLite said. I am going with 4 core, but the reason behind that is that I run a database server and use workstation programs (Solidworks, Adobe creative suite), in addition to playing games. The way I see it, if I have to have the hardcore programs running on the darn server...

Here's my rig! 32,768 PowerPC 440 700Mhz Processors; 70.72 TFlops Computing power. :eek: HAHA, I couldn't resist. BTW, this computer is called BlueGene/L DD2. It is owned by IBM. More info can be found here and here. :D

Wow...didn't know a database existed like this. But these are manufacturer's specs, right? Manufacturer's specs are sketchy at best.

I understand that a fan shroud will decrease noise and decrease the amount of "dead space" from the center of the fan (as well as back pressure), but does anyone have any real numbers as to how much efficiency is increased by including a fan shroud? The application I am using it for is a black...

You probably won't need 1/2" tubing for only the CPU and chipset. The pump powers up when you power up the computer. The CPU won't overheat in the seconds it takes to get the water flowing. The CPU block will always be filled with water regardless of whether or not your computer is on...you...

Personal preference. Both are good. Both companies get consistently high marks in the reviews, so you can't really go wrong with either. Honestly, I think the Danger Den components look better than the Swiftech :D

Umm...this is wrong...TDX has 1 outlet, RBX has 2

Honestly, it depends on the speed of your hard drives. If they are 7200RPM drives, I wouldn't worry too much. Higher drive temps will lower the life of your drives, but if you are like me, that won't be an issue (because I buy new drives every year or so anyways). If you are really worried...

Just to clarify things here: almost all "kits" do not include a waterblock for the chipset. Some kits don't come with ANY waterblocks. Some kits come with BOTH. With all that aside, I would suggest Danger Den (once again). Their kit doesn't include the chipset waterblock, but everything...

I was just wondering if it really is necessary? What kind of performance increases can you expect with a shroud (1" stand-off)? For example: what would perform better...a 2x 120 rad with a shroud or a 3x 120 rad without a shroud? Having a long and flat radiator vs a short and tall radiator...

I'd go with Danger Den. It is a nice balance of price, ability to customize, simplicity and performance. Also, it is one of the more documented water-cooling solutions out there (i.e. has many reviews and lots of community support).

Honestly, I am surprised no one has done a dB vs CFM shootout for fans. You don't need an anechoic chamber...just consistent testing methods. I guess the main problem is measuring CFM. Airflow meters aren't cheap. The reality of all this is higher CFM means higher dB. So nexus will...

Personally, I think that cmstacker 2 is fugly. But that's me.

This is the cooling scheme that I have planned out for the moment. Any suggestions are welcome :) Anyone have any experience with Gorman-Rupp pumps? Are they loud? Radiator->Reservoir->Pump-> 2x CPU (in parallel) -> two lines in parallel {1st: nVidia 2200, nVidia 2050, AMD 8131} {2nd: 2x...

Papst. Good luck finding them though.

I accidentally posted in the regular OC and Cooling forum, so I am reposting here (sorry for the double posts everyone). I'm working on a water-cooled dual opteron, dual gpu system. I am a little worried about the amount of heat the pump might put into the system (I am thinking of using a...

Oops...I'll repost there. Forgot about the watercooling forum Yeah...I planned to place the res before the pump intake, but the radiator directly after the pump output. I have access to industrial pneumatic fittings, tubing, etc. so all of that will be from SMC Pneumatics. As for...

A lot of it is trial and error. You try a setting...if it works, ramp it up a little...wash, rinse, repeat. Make sure that between tweaks you load the cpu (run benchmarks or something like that). I would tweak the CPU first. Work on getting it as fast as possible without any changes to...

I'm working on a water-cooled dual opteron, dual gpu system. I am a little worried about the amount of heat the pump might put into the system (I am thinking of using a Gormann-Rupp pump). I was toying with the idea of putting the radiator inline directly after the outlet on the pump rather...

1080i does, in fact, take about 1/2 the processing power as 1080p (if the field rate of the 1080i and the frame rate of 1080p were equal--which is the case). 1080i only shows 1/2 the actual number of lines of resolution that 1080p does every time the screen is refreshed. THAT being said, the...

I don't want to use peltiers but if I need to, I will. I, however, don't want it boiling my fluid, so how hot do peltiers get on the hot side? Another question on your thinktank...how much power are you consuming on the whole system (including all cooling apparatus)? Thanks -m

Law of Conservation of Energy: energy cannot be created or destroyed. Which brings me to my last question: Where are you getting 1 kW of energy to be dissipated? Assuming you are running a 600 Watt power supply AND all of your components are perfect heat generators, that means that you...

I have a couple of questions regarding the Thinktank: 1. How are your peltiers set up? Are they connected straight to the fluid case? How are you maximizing the amount of heat transfer from the fluid to the peltiers? Are you using a heatsink/coldsink combo to maximize heat transfer? (I...

Just wondering if any of you all considered working with R/C boat parts (i.e. propeller or impeller) to circulate the fluid. They use nylon propellers so you don't have to worry about incompatability of the fluid with the prop. You can mate any kind of motor to the propeller as well, if you...
